Allelopathy of Aspergillus japonicus on Crops
Steffens and Robeson, 1987). The compound inhibited the onion seedling elongation by 4, 32, 40, 68, and 94% The seeds of some dicotyledons fail to germinate and grow well at concentrations of 1029, 1028, 1027, 1026, and 1025 M, when contaminated by Aspergillus japonicus Saito. One strain of A. japonicus isolated from the seeds of contaminated rape (Brassica respectively. Penicillium oxalicum, w...
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 کاملCover Crops in Sustainable Food Production
Cover crops are important components of sustainable agricultural systems. They increase surface residue and aid in the reduction of soil erosion. They improve the structure and water-holding capacity of the soil and thus increase the effectiveness of applied N fertilizer. Legume cover crops such as hairy vetch and crimson clover fix nitrogen and contribute to the nitrogen requirements of subseq...
متن کاملWinter Cover Crops in Illinois: Evaluation of Ecophysiological Characteristics of Corn
Understanding ecophysiological characteristics of corn (Zea mays L.) under winter cover crops (WCCs) can improve management and farmers’ acceptance by increasing the positive effects and decreasing the negative effects associated with their use. This study was conducted to quantify the effects of WCC on corn development, growth, and yield through the evaluation of ecophysiological characteristi...
متن کاملEfficacy of Cotton Root Destruction and Winter Cover Crops for Suppression of Hoplolaimus columbus.
The efficacy of rye (Secale cereale) and wheat (Triticum aestivum) winter cover crops and cotton stalk and root destruction (i.e., pulling them up) were evaluated in field tests during two growing seasons for Hoplolaimus columbus management in cotton. The effect of removing debris from the field following root destruction also was evaluated. Wheat and rye produced similar amounts of biomass, an...
