Crop Diversity for Yield Increase
Traditional farming practices suggest that cultivation of a mixture of crop species in the same field through temporal and spatial management may be advantageous in boosting yields and preventing disease, but evidence from large-scale field testing is limited. Increasing crop diversity through intercropping addresses the problem of increasing land utilization and crop productivity. In collabora...
متن کاملNitrogen, Aldicarb, and Cover Crop Effects on Cotton Yield and Fiber Properties
ducted with modern cotton cultivars (Touchton et al., 1984; Bauer et al., 1993; Daniel et al., 1999; Larson et Thrips, primarily Frankliniella spp., can damage cotton (Gossypal., 2001). Grass cover crop residues generally have a ium hirsutum L.) seedlings. The objectives of this study were to determine the effect of winter cover crops on thrips populations in high C/N ratio, which causes N immo...
متن کاملTopography Mediates the Influence of Cover Crops on Soil Nitrate Levels in Row Crop Agricultural Systems.
Supplying adequate amounts of soil N for plant growth during the growing season and across large agricultural fields is a challenge for conservational agricultural systems with cover crops. Knowledge about cover crop effects on N comes mostly from small, flat research plots and performance of cover crops across topographically diverse agricultural land is poorly understood. Our objective was to...
متن کاملPrioritizing Crop Management to Increase Nitrogen Use Efficiency in Australian Sugarcane Crops
Sugarcane production relies on the application of large amounts of nitrogen (N) fertilizer. However, application of N in excess of crop needs can lead to loss of N to the environment, which can negatively impact ecosystems. This is of particular concern in Australia where the majority of sugarcane is grown within catchments that drain directly into the World Heritage listed Great Barrier Reef M...
متن کاملWheat Yields, Nitrogen Uptake, and Soil Moisture Following Winter Legume Cover Crop vs. Fallow
Long-term use of fallow in dryland wheat (Triticum aestivum L.) systems can increase erosion and decrease soil fertility. One possible solution is to grow a green manure crop during the fallow period. To evaluate the short-term effects of substituting a winter legume green manure for fallow in a 2-vr wheat rotation, a series of experiments were conducted in the Sacramento Valley of California f...
