Crop rows
A row crop tractor

A row crop is a crop that can be planted in rows wide enough to allow it to be tilled or otherwise cultivated by agricultural machinery, machinery tailored for the seasonal activities of row crops.[1] Such crops are sown by drilling or transplanting rather than broadcasting. They are often grown in market gardening (truck farming) contexts or in kitchen gardens. Growing row crops first started in Ancient China in the 6th century BC.[2]

The distinction is significant in crop rotation strategies, where land is planted with row crops, close-growing grains, and sod-forming crops in a sequence meant to protect the quality of the soil while maximizing the soil's annual productivity.[3]

As much of 20% of crops worldwide are irrigated, with some crops such as rice and maize benefiting from the extra water.[4] During the growing season, the inter-row spaces are hoed two to four times and the rows are weeded to conserve moisture and improve aeration. As a result, the soil's microbiological activity increases and mobilization of nutrients is intensified. Row crops are valuable precursors of spring grain crops, flax, and hemp. The beneficial effect of row crops extends to the second crop.

Examples of row crops include sunflower, potato, canola, dry bean, field pea, flax, safflower, buckwheat, cotton, maize, soybeans, and sugar beets.

A row crop is an agricultural crop planted in straight rows spaced widely enough to allow mechanical cultivation, such as tilling or weeding, between the rows using specialized farm equipment. This planting method optimizes efficiency for large-scale farming by enabling the use of and implements tailored for row-based operations, distinguishing row crops from close-sown or broadcast varieties like hay or grasses. Common examples include commodity crops such as corn, soybeans, , , , , and , which are primarily annual grown for , oil, , or other uses. Row crops form the backbone of modern commercial agriculture worldwide, particularly in regions like the U.S. Midwest and Southern states, where they dominate cultivated cropland and drive economic output through food, feed, fuel, and export markets. In the United States, major row crops like soybeans, corn, wheat, and cotton account for a significant portion of farm exports, valued at approximately $60 billion annually as of 2023, supporting rural economies and global trade. Production practices emphasize soil preparation, precision planting, pest management, and crop rotation to maintain soil health and yields, with extension services providing guidance on sustainable techniques to address environmental challenges like erosion and nutrient runoff. The cultivation of row crops has evolved with advancements in since the early , shifting from labor-intensive methods to high-yield, technology-driven systems that enhance productivity but require careful . Today, they represent a critical segment of global , with ongoing research focusing on resilient varieties and to adapt to climate variability and market demands.

Definition and Characteristics

Definition

Row crops refer to agricultural plants that are cultivated in straight, evenly spaced rows sufficiently wide to permit the passage of mechanized equipment for operations such as , cultivation, weeding, and harvesting. This planting arrangement, often achieved through seeds rather than them, allows for precise spacing that supports uniform growth and efficient machinery use. In contrast to other planting methods, row cropping differs from broadcasting, where seeds are sown broadly over the soil surface for close-grown crops like hay or pasture grasses without distinct rows, and from intercropping, which mixes multiple crop species in the same area to maximize land use. It also stands apart from perennial plantings, such as orchards or pastures, which involve long-term, non-annual establishments not requiring annual replanting or row-based mechanical intervention. The primary purpose of row cropping is to optimize large-scale, industrial agriculture by emphasizing uniformity, accessibility for machinery, and streamlined management practices that enhance productivity and reduce labor intensity.

Key Characteristics

Row crops are characterized by their uniform row spacing, which varies by crop but typically ranges from 30 to 40 inches for corn and similar row crops to provide sufficient clearance for agricultural machinery such as tractors and cultivators. This spacing facilitates efficient mechanical operations while allowing for optimal plant density, varying widely by crop—for example, around 25,000 to 35,000 plants per acre for corn—to maximize access to sunlight, water, and nutrients by reducing intra-row competition and promoting even resource distribution. Higher densities in narrower rows can enhance light interception and nutrient uptake, though wider spacings are preferred in mechanized systems to avoid equipment interference. Unlike perennial crops, row crops exhibit annual or seasonal growth cycles, completing their life from seed to harvest within a single of 6 to 12 months, necessitating replanting each year to maintain . This cyclical nature allows for and but requires precise timing for planting to align with environmental conditions like and availability. The linear arrangement of row crops makes them particularly suitable for row-specific practices, including and furrowing, which involve creating raised beds or channels to direct water flow and improve drainage. These techniques, combined with inter-row cultivation, enable effective by disturbing soil between rows without damaging crop plants, while also mitigating through water shedding from ridges and reduced runoff velocity in furrows.

History

Early Development

The origins of row crop farming trace back to ancient civilizations where rudimentary aligned planting emerged as a response to the need for organized cultivation amid challenging environmental conditions. In , around 3000 BCE, early farmers developed the seeder plow, a wooden implement pulled by oxen that created furrows in the soil while simultaneously dropping seeds such as and into them, effectively establishing proto-rows for more efficient sowing and management. This innovation, refined by the 2nd millennium BCE, allowed seeds to be buried at consistent depths, reducing exposure to birds and wind while facilitating water distribution in the arid Tigris-Euphrates valley. Similarly, in , evidence of (corn) cultivation dates to approximately 7000 BCE in regions like the Balsas River valley, where indigenous groups managed early and planting in the region's variable rainfall and volcanic soils. By the 1st century CE, Roman agricultural practices further formalized row planting as a means to enhance efficiency and maintenance. Lucius Junius Moderatus , in his comprehensive treatise De Re Rustica, advocated for precise spacing in aligned rows—such as three-foot intervals between plants and five-foot gaps between rows—for crops like vines and cereals, enabling easier access for weeding, fertilizing, and harvesting with hand tools. Columella emphasized that such systematic arrangement minimized labor waste and maximized yields by allowing cultivators to navigate between rows without damaging plants, drawing on earlier Hellenistic influences to promote this method across the empire's diverse climates. These texts influenced subsequent European farming, where row-like planting was recommended for small-scale operations to optimize exposure and aeration. Prior to the , row adoption remained constrained by reliance on manual labor, limiting its scale primarily to suppression in modest fields. Farmers hoed or pulled by hand between rows using sickles, adzes, or simple mattocks, a labor-intensive process that required entire families or communal efforts during the to prevent competition. Without mechanical aids, rows served mainly as pathways for foot traffic and basic rather than large-scale production, as seeds remained more common for grains due to the time demands of precise planting. This pre-industrial approach sustained needs but restricted expansion, as manual weeding was highly labor-intensive for row-planted crops like .

Modern Advancements

The represented a pivotal shift in row crop agriculture, driven by technological innovations that addressed the challenges of expanding cultivation into the fertile but tough soils of the American Midwest. In 1837, blacksmith developed the first commercially successful self-scouring steel plow, which effectively sliced through the dense, sticky sod that had previously resisted cast-iron plows, enabling deeper and more efficient tillage for row-planted crops. This breakthrough facilitated the rapid settlement and agricultural development of Midwestern regions, allowing farmers to convert vast grasslands into productive fields for row crops such as corn and , thereby supporting the region's emergence as a major grain-producing area. The 20th century accelerated these advancements through widespread , particularly in the post-World War II era, when surplus military technologies and increased investment in agricultural research spurred the adoption of tractors, combines, and other machinery tailored for row crop operations. This mechanization boom complemented earlier genetic innovations, such as the commercialization of hybrid corn seeds in , which produced more vigorous and higher-yielding plants suited to uniform row planting and significantly boosted productivity. By the 1970s, the introduction of broad-spectrum chemical herbicides like , first marketed in 1974, transformed weed management in row crops by providing effective, non-selective control that minimized manual labor and enhanced crop establishment. These developments collectively reduced operational costs and increased scalability for large-scale row crop farming. Entering the , technologies integrated digital tools into row crop systems, with GPS-guided planting emerging as a cornerstone by the early 2000s to optimize row alignment and variable-rate applications. These systems enabled automated steering of equipment, ensuring precise seed placement and spacing that reduced overlaps, conserved inputs like and fertilizers, and improved overall field efficiency for crops such as soybeans and . By the mid-2000s, autosteer technologies had become standard on modern machinery, marking a transition toward data-driven row crop management that further amplified yields while addressing resource limitations.

Types and Examples

Major Row Crops

Corn (maize), known botanically as Zea mays, is a tall annual grass that grows to heights of 2-3 meters, featuring a single main stalk with broad leaves and tassels for pollination. Its growth habit necessitates wide row spacings, typically 76 cm (30 inches), to accommodate machinery and optimize light interception for high-yield potential in row systems. Globally, corn dominates row crop acreage, with harvested areas exceeding 200 million hectares as of 2024, underscoring its role as a staple for food, feed, and industrial uses. Soybeans (Glycine max), a with an erect, bushy growth habit reaching 0.6-1.5 meters, exhibit high-yield potential in row configurations due to their indeterminate or determinate varieties that branch profusely. A key agronomic trait is their symbiotic nitrogen-fixing roots, which associate with to convert atmospheric into usable forms, enhancing and enabling yields up to 3-4 tons per hectare in rotations. Worldwide harvested area for soybeans stands at approximately 134 million s as of 2022, supporting its status as a major protein and oil crop. Wheat (Triticum aestivum), a cool-season annual grass with a tillering growth habit that produces multiple stems from the base, thrives in narrow rows of 15-20 cm to maximize tiller density and grain fill. Its agronomic profile includes robust root systems and vernalization requirements for winter varieties, contributing to high yields of 3-8 tons per hectare under intensive row management. Global wheat harvested area reaches about 222 million hectares as of 2022, making it one of the most extensively cultivated row crops for human consumption. Cotton ( spp.), an indeterminate perennial shrub managed as an annual, develops a woody base with branching stems up to 1-2 meters tall, bearing bolls of and . In row systems, spacings of 76-102 cm (30-40 inches) support its sprawling habit while facilitating mechanical cultivation, with yield potentials of 1-2 tons of lint per hectare. Harvested area globally is approximately 32 million s as of 2022/23, highlighting its economic importance in production. Rice (paddy varieties of Oryza sativa), a semi-aquatic annual grass with tillering similar to wheat, is grown in flooded rows to control weeds and support straight growth up to 1 meter. Its agronomic traits include high tiller production and responsiveness to transplanting, enabling yields of 4-8 tons per hectare in intensive systems. Paddy rice occupies approximately 168 million hectares worldwide as of 2023, serving as a dietary staple for billions. Barley ( vulgare), a cool-season annual grass similar to , features a tillering and is grown in rows typically spaced 15-20 cm apart to promote dense stands and efficient harvesting. It is valued for its versatility in , feed, and , with global yields ranging from 2.5-4 tons per under optimal conditions. Worldwide, barley occupies about 50 million s as of 2022, contributing to diverse agricultural systems.

Regional and Specialized Types

In arid and semi-arid regions of and , and serve as key row crops valued for their and ability to thrive in marginal soils with limited water availability. These crops are often planted in rows by smallholder farmers as a resilient alternative to more water-demanding staples, providing and while hedging against erratic rainfall patterns. In the U.S. Southeast, and represent prominent cash row crops adapted to the region's and sandy soils, with Georgia leading national production of both. are typically sown in rows to facilitate mechanical harvesting, contributing significantly to local economies through and . , transplanted into rows after propagation, supports high-value flue-cured varieties suited to the area's growing conditions. Specialized row crops include vegetables such as tomatoes and potatoes, which are cultivated in intensive systems to maximize yields on limited land through precise spacing and management. Tomatoes in these setups often involve staked or trellised rows for efficient space use and disease control, while potatoes are hilled in rows to promote tuber development in high-density plantings. Cover crops like clover can also be established in rows as living mulches, offering soil protection by suppressing weeds, fixing nitrogen, and reducing erosion between main crop seasons. Row spacing adaptations vary by crop purpose and region; high-density vegetable systems, such as those for tomatoes or potatoes, commonly employ narrower rows of 12-18 inches to optimize light interception and resource use. In contrast, fiber crops like cotton typically use wider rows of 30-40 inches to accommodate machinery and allow for bushy growth that supports boll development.

Cultivation Practices

Planting and Maintenance

Soil preparation for row crops begins with practices tailored to the row-based planting system, which facilitates machinery access and uniform seed placement. Conventional involves plowing and disking to create a fine , inverting to bury crop residues and while aerating the ground for root development. In contrast, conservation methods such as no-till leave surface residues intact to reduce and improve , with seeds placed directly into undisturbed using specialized planters. , a hybrid approach, disturbs only the narrow row zones—typically 6-8 inches wide—to warm and incorporate fertilizers while preserving residue between rows for moisture retention and suppression. These types are selected based on , , and row spacing standards, which generally range from 15 to 40 inches to optimize light interception and equipment operation. Planting row crops primarily employs direct seeding via drills or planters that create furrows at precise depths and spacings, ensuring even distribution in straight rows for efficient cultivation, often using GPS-guided precision technology for variable rate application. Seed drilling is standard for major row crops like corn and soybeans, where seeds are metered into the soil at rates of 30,000-40,000 per acre for modern corn hybrids, with depths of 1.5-2 inches to promote germination. Timing is critical and crop-specific; in temperate zones, corn is planted in spring once soil temperatures reach at least 50°F (typically April to May) to avoid chilling injury and ensure rapid emergence within 10-14 days. Soybeans follow similar spring planting windows, often May to early June, when soils warm to 60°F for optimal nodulation and growth. Transplanting, though less common for large-scale field row crops, is used for certain vegetables like tomatoes or peppers in row systems, where seedlings are set into rows after 4-6 weeks of greenhouse growth to extend the season and reduce field exposure risks. Ongoing maintenance during the focuses on protecting row crops from competition and damage while sustaining . Inter-row weeding through mechanical cultivation—using sweeps or rotary hoes—controls weeds between rows without disturbing roots, often performed 2-4 times post-emergence when crops are 4-6 inches tall. Pest scouting involves weekly field walks to monitor for , diseases, and deficiencies, enabling targeted interventions like threshold-based spraying to minimize chemical use. , such as alternating corn with soybeans in a two-year cycle, prevents depletion—particularly nitrogen drawdown by corn—and disrupts pest cycles, improving long-term field productivity. These practices, integrated with and fertilization, support vigorous growth until maturity.

Harvesting and Post-Harvest

Harvesting of row crops typically involves mechanized equipment to efficiently collect mature plants while minimizing losses and damage. For row crops such as corn and , combine harvesters equipped with row-specific headers are standard, where corn heads use gathering chains and stripper plates to align with and remove ears from spaced rows, reducing stalk breakage and foreign material intake. These headers must match the planter's row spacing—typically 30 inches for corn—to avoid misalignment losses of up to 2.5 bushels per acre. For , table headers with bars cut across rows at adjustable heights to capture heads effectively. In contrast, delicate like often rely on mechanical pickers with rotating spindles that selectively remove from opened bolls, achieving 70-97% efficiency while preserving over hand-picking methods. Hand-picking remains viable for small-scale or high-value operations to avoid trash , though it yields typically 15-20 kg per day per worker in labor-intensive regions like , or up to 50-100 kg per day for experienced workers elsewhere. Timing harvest is critical to balance yield, quality, and machinery efficiency, guided by maturity indicators such as kernel moisture content and physiological markers. For corn, optimal harvest occurs when grain moisture reaches 19-25%, allowing combines to operate without excessive kernel damage, though field drying may extend to 15-18% for direct storage. Physiological maturity is confirmed by the black layer at the kernel base, typically at 30-35% moisture, after which deterioration accelerates if not harvested promptly. Desiccants, such as sodium chlorate or ethephon-based harvest aids, are applied to cotton when 60% of bolls are open to accelerate leaf drop and boll opening, promoting uniform row maturity and reducing regrowth in variable fields. These chemicals, applied at rates like 4.5 lb/acre for sodium chlorate, enable timely mechanical harvest above 60°F, minimizing weather-related losses. Post-harvest handling focuses on preserving quality through drying, cleaning, and controlled storage to avert spoilage from mold, insects, or respiration. Grain from row crops like corn and wheat is dried to 14-15.5% moisture using continuous-flow systems at 120-160°F, preventing heat damage while removing excess water—wet corn at 25% requires about 22 hours versus 12 hours at 20%. Cleaning follows to eliminate broken kernels, foreign material, and fines via screens and aspirators, reducing biological activity and aeration issues in storage. Storage occurs in ventilated silos or bins at cool temperatures below 60°F with aeration at 0.1-0.25 cfm per bushel, maintaining viability for 6 months or more and doubling safe holding time per 10°F drop. Quality grading adheres to USDA standards, assessing factors like test weight (minimum 56 lb/bu for U.S. No. 1 corn), damaged kernels (≤3%), and foreign material (≤2%) post-dockage removal to ensure market value. For cotton, grading evaluates fiber length, strength, and micronaire via High Volume Instrument (HVI) systems, with mechanical harvest often increasing trash content to 14-18% if not pre-cleaned.

Economic and Agricultural Role

Production and Yield

Row crops, including staples such as corn, soybeans, wheat, and rice, constitute a significant portion of global agricultural output, with total primary crop production reaching 9.6 billion tonnes in 2022, where maize, wheat, and rice alone accounted for nearly half. In the 2024/2025 marketing year, global cereal production, encompassing key row crops like corn and wheat, is forecast to hit a record 2,990 million tonnes, up 4.4% from 2024, driven by expanded harvested areas and improved yields in major producing regions. Regional production is concentrated in a few leading countries; for instance, the United States dominates corn output at 377.63 million metric tons (31% of global share), followed by China at 294.92 million metric tons (24%), and Brazil at 135 million metric tons (11%), contributing to a worldwide total of approximately 1,219 million metric tons. Similarly, rice production is led by China with 211.86 million tonnes and India with 178.31 million tonnes, supporting a global milled equivalent of 535.8 million tonnes. Soybean output centers in Brazil (169 million metric tons, 40% global) and the United States (118.84 million metric tons, 28%), with total production forecasted at 425.4 million metric tons. Wheat production, projected at 793 million metric tons globally, is spearheaded by China, India, and Russia, which together account for about 41% of the total. Yield factors for row crops have been profoundly influenced by the adoption of hybrid varieties, which enhance genetic uniformity, resistance, and overall productivity compared to traditional open-pollinated seeds. In the United States, for example, corn yields stagnated at around 26 bushels per acre (approximately 1.6 tonnes per ) until the late but have since risen to averages exceeding 170 bushels per acre (over 10 tonnes per ) through hybrid development, representing a genetic gain of about 1.9 bushels per acre per year since the mid-1950s. For , modern hybrid and semi-dwarf varieties have elevated global average yields to 3.5-4 tonnes per , a substantial over historical levels of 2-3 tonnes per in the early , primarily due to better efficiency and lodging resistance. These advancements stem from techniques that promote hybrid vigor, allowing row crops to achieve higher accumulation and grain fill under conditions. Production trends for row crops show consistent increases attributable to biotechnological innovations, particularly since the introduction of genetically modified organisms (GMOs) in the mid-1990s. For , GMO herbicide-tolerant varieties, first commercialized in 1996, have expanded to cover 94% of U.S. planted acres by 2020, contributing to yield gains through reduced competition and simplified management, with global GM production adding an estimated 180.3 million tonnes cumulatively from 1996 to 2015. Overall, GM crops have boosted global farm output by facilitating higher yields in pest-prone areas; for instance, in 2018 they generated an additional $18.9 billion USD in farm income, with a cumulative $225.1 billion from 1996 to 2018 while increasing production volumes across row crops like corn and . According to FAO data up to 2024, these biotech trends, combined with , have driven a 56% rise in primary crop production since 2000, with row crops benefiting from expanded GMO adoption in over 30 countries and a global biotech area of 206.3 million hectares. Projections for 2025 indicate continued growth, with yields rising 1-2% annually due to these factors.

Market Dynamics

Row crop markets are characterized by active trading, primarily through standardized futures contracts that facilitate and hedging against risks. Corn and soybeans, two of the most prominent row crops, are traded on the exchanges, including the historic (CBOT), where contracts specify delivery grades, quantities, and locations to ensure liquidity and transparency for global participants. These futures markets handle billions of bushels annually, allowing producers to prices ahead of and processors to secure supply amid fluctuating conditions. Price volatility remains a defining feature of row crop markets, driven by external shocks that affect balances. Weather events, such as droughts in key producing regions like the U.S. Midwest or excessive rainfall in , can sharply reduce yields and propel prices upward, as seen in corn market swings tied to La Niña patterns. Geopolitical factors, including trade tensions between major importers like and exporters, or conflicts disrupting Black Sea grain flows, further amplify uncertainty, with studies showing elevated geopolitical risk indices correlating to heightened futures volatility in grains. The for row crops spans from farm-level production through processing, distribution, and , creating interconnected economic flows that influence global . In the United States, soybeans exemplify this chain, with harvested beans processed into meal for feed and oil for various uses before ; this pathway supports a robust export sector, where shipments to —a primary destination—have exceeded $15 billion in value during the . For instance, in 2022, U.S. soybean exports to totaled $16.4 billion, accounting for nearly half of all U.S. agricultural exports to the country and underscoring the crop's role in dynamics. Policy interventions, particularly through the U.S. Farm Bill, play a pivotal role in stabilizing and incentivizing row crop markets via subsidies and demand-side supports. The Farm Bill's crop insurance provisions, authorized under Title XI, subsidize up to 60% of premiums for producers of row crops like corn and soybeans, reducing financial exposure to yield losses and encouraging acreage expansion; extensions of the 2018 Farm Bill through 2025 and into 2026 for key programs have maintained these supports at over $10 billion annually in federal outlays. Complementing this, energy programs and mandates under the Renewable Fuel Standard bolster biofuels demand, requiring blending of corn-derived into and thereby sustaining elevated production levels for row crops amid volatile markets.

Environmental and Sustainability Aspects

Benefits to Farming Systems

Row crop agriculture enhances farming systems through significant efficiency gains, primarily enabled by , which reduces labor requirements and supports larger-scale operations. Mechanized planting, cultivation, and harvesting in uniform rows allow for faster and more precise field operations, minimizing manual labor while increasing productivity. For instance, the adoption of machinery in row crop production has historically contributed to rising agricultural output with fewer workers, enabling farms to expand and contribute to global by boosting crop yields to meet growing populations. This scalability is particularly evident in major row crops like corn and soybeans, where mechanization facilitates consistent, high-volume production across vast areas. Rotations within row crop systems further support and fertility by diversifying nutrient demands and reducing depletion from practices. By alternating crops such as corn with soybeans or , farmers improve , enhance nutrient cycling, and increase overall fertility, leading to higher long-term yields without excessive external inputs. These rotations also promote by breaking pest and disease cycles, allowing for more resilient ecosystems within the farm. (IPM) strategies, tailored to row configurations, minimize chemical overuse by combining monitoring, biological controls, and targeted interventions, thereby preserving beneficial insects and reducing environmental impacts while maintaining crop protection. The adaptability of row crop systems to challenges is bolstered by techniques, such as variable-rate application of s, which optimize inputs based on variability and conditions. This approach enhances , reduces waste, and improves crop resilience to stressors like or erratic rainfall by ensuring nutrients are delivered precisely where needed. For example, adjusting rates in row patterns can lower leaching risks and support sustainable yields under changing climates, contributing to broader farming system stability.

Challenges and Mitigation

Row crop farming, particularly through conventional practices, contributes significantly to , with average annual losses on U.S. cropland estimated at approximately 4.6 tons per acre (about 11.3 tons per ) as of 2017 according to the USDA National Resources Inventory, though rates have continued to decline with conservation efforts and can still exceed 10 tons per in intensively tilled fields. This erosion is exacerbated by the exposed soil between rows during planting and cultivation, leading to the loss of essential for long-term productivity. Additionally, runoff from row crop fields carries sediments, fertilizers, and pesticides into waterways, making agricultural the leading cause of impairments to rivers and streams . and from these sources, often linked to tile-drained row crop systems like corn and soybeans, contribute to and hypoxic zones in downstream waters. Monoculture systems dominant in row crop production further diminish by simplifying habitats, reducing and populations, and limiting soil microbial diversity compared to more varied cropping systems. This loss affects services such as natural and , with studies indicating significant reductions in wild diversity in intensive row crop landscapes. To address , conservation tillage—leaving at least 30% on the surface—has been widely adopted, covering about 70% of major U.S. row crop acreage like corn and soybeans by the early . Cover cropping during off-seasons suppresses by protecting and enhancing infiltration, reducing leaching by up to 61% in Midwestern row crop systems. Vegetative buffer strips along field edges and waterways trap sediments and nutrients, mitigating runoff pollution by 40-90% for particulate and sediments in agricultural settings. Emerging regenerative practices, including integrated with cover crops, further build and reduce rates to below 2 tons per hectare annually in adapted systems. technologies, such as GPS-guided variable-rate application, enable targeted inputs in row crops, cutting use by up to 15% and other inputs like by 20-30% while maintaining yields, according to 2025 analyses of U.S. Midwestern farms. These approaches, often combined with brief rotations, enhance overall resilience against . As of 2025, USDA initiatives have expanded climate-smart practices in row crop systems, promoting and adaptation to climate variability.
