Abstract
Abstract With the economic need for conservation of fuel, equipment, time, and labor, reducing inputs becomes increasingly important. A field experiment was conducted to determine the effectiveness of cultural practices such as in‐the‐row subsoiling, reduced preplant tillage, and reduced post‐plant tillage on silt loams and clay soils of the Mississippi River Delta and loessial plains. The experiment was conducted at the same sites on four soils for five growing seasons. The yield response of cotton (Gossypium hirsutum L.) to these cultural practices was determined. Minimum seedbed preparation averaged two tillage trips less than conventional seedbed preparation and post‐plant mechanical cultivations averaged 3.3 trips each year. At harvest, no significant difference due to cultural practices were found with plant population, plant heights, or percent lint at first picking. Lint yield differences as influenced by seedbed preparation were nonsignificant. Post‐plant cultivation resulted in 100 kg/ha higher lint yield on those soils that restricted root penetration. No differences due to tillage were found in the seasonal petiole nitrate concentrations indicating that mechanical tillage did not appreciably influence the ratio of nitrogen (N) to dry matter in the cotton plants. Soil water content of the conventional seedbed preparation with post‐plant cultivation was generally higher than the reduced seedbed preparation. This was attributed to an increase in infiltration and decrease in evaporation of water.
