Interactions among leguminous trees, crops and weeds in a no-till alley cropping system
Trees improve the soil quality and their rapid growth in the tropics make agroforestry systems potentially effective for establishing low-input agricultural systems in this region. This study assessed the effects of the biophysical interactions among leguminous trees, weeds, cotton and maize in an alley cropping system. The experiment comprised six treatments: Clitoria + Gliricidia; Acacia ...
متن کاملGround Beetle (Coleoptera: Carabidae) Assemblages in Organic, No-Till, and Chisel-Till Cropping Systems in Maryland
Ground beetle assemblages were compared in organic, no-till, and chisel-till cropping systems of the USDA Farming Systems Project in Maryland. The cropping systems consisted of 3-yr rotations of corn (Zea mays L.), soybean (Glycine max L. Merr.), and wheat (Triticum aestivum L.) thatwereplanted to cornand soybeanduring the2yrofÞeld sampling (2001Ð2002).Eachyear, ground beetles were sampled usin...
متن کاملIncreased Dryland Cropping Intensity with No-Till Barley
for increasing cropping intensity, improving soil quality, and controlling erosion in the conventional fallow areas For most of a century, the wide spread practice of growing only (Papendick, 1998). However, research with spring crops, one crop every other year in a tillage-based wheat (Triticum aestivum L.)–fallow rotation has degraded soils and contributed to environmenand in particular with ...
متن کاملConversion to No-Till Improves Maize Nitrogen Use Efficiency in a Continuous Cover Cropping System
A two-year experiment was conducted in the field to measure the combined impact of tilling and N fertilization on various agronomic traits related to nitrogen (N) use efficiency and to grain yield in maize cultivated in the presence of a cover crop. Four years after conversion to no-till, a significant increase in N use efficiency N harvest index, N remobilization and N remobilization efficienc...
متن کاملCover crop root contributions to soil carbon in a no-till corn bioenergy cropping system
Crop residues are potential biofuel feedstocks, but residue removal may reduce soil carbon (C). The inclusion of a cover crop in a corn bioenergy system could provide additional biomass, mitigating the negative effects of residue removal by adding to stable soil C pools. In a no-till continuous corn bioenergy system in the northern US Corn Belt, we used CO2 pulse labeling to trace plant C from ...
