Soybean growth and yield under cover crops

Cover crops and herbicide timing management on soybean yield under no‐tillage system

The objective of this work was to evaluate the effect of cover crops and timing of pre-emergence herbicide applications on soybean yield under no-tillage system. The experiment consisted of four cover crops (Panicum maximum, Urochloa ruziziensis, U. brizantha, and pearl millet) and fallow, in addition to four herbicide timings (30, 20, 10, and 0 days before soybean sowing), under no-tillage sys...

Root growth and yield of maize as affected by soil compaction and cover crops

The yield of rainfed crops is commonly limited by the availability of soil water during the summer growing season. Channels produced by cover crop roots in fall/winter when soils are relatively moist may facilitate the penetration of compacted soils by subsequent crop roots in summer when soils are relatively dry and hard. Our objective was to determine the effects of fall cover crops on maize ...

Yield losses of soybean and maize by competition with interseeded cover crops and weeds in organic-based cropping systems

Weed management is a major issue in organic farming systems. Although interseeding cover crops is one alternative to herbicides, cover crops often suppress not only weeds but also main crops. Therefore, using cover crops for weed control without adverse effects on main crop growth is important. To verify the effect of cover crops on competition between main crops, cover crops and weeds in snowy...

Effect of Incorporation of Leguminous Cover Crops on Yield and Yield Components of Maize

The low and declining productivity of many tropical soils are the major constraints limiting the realization of the improved genetic potential of crops that are now available. The need to take appropriate measures to check this decline in soil productivity is urgent as the rate of deterioration is on the increase and if not checked will have serious implications for future food demands of the i...
