Summer Cropping Effects on the Abundance of Meloidogyne arenaria Race 2 and Subsequent Soybean Yield.
A summer-planted crop of alyceelover significantly (P < 0.05) increased the soil abundance of Meloidogyne arenaria race 2 juveniles by 3.7-fold when measured in the following spring. Maize, sorghum, and soybean had no significant effects on residual nematode numbers over the same period. Summer plantings of aeschynomene, cotton, hairy indigo, tespedeza, millet, peanut, and sorghum-sudangrass we...
متن کاملBiological Nitrogen Fixation of Summer Legumes and Their Residual Effects on Subsequent Rainfed Wheat Yield
Biological nitrogen fixation is the most important biochemical reaction for life on earth. Phosphorus and rhizobium inoculation increased N2-fixation by legumes. Legumes in rotation with cereals contribute to the total N pool in soil and improved cereals yield. In view of importance of grain legumes and the role they can play in maintaining soil productivity and succeeding cereal yield, rotatio...
متن کاملeffect of seed priming and irrigation regimes on yield,yield components and quality of safflowers cultivars
این مطالعه در سال 1386-87 در آزمایشگاه و مزرعه پژوهشی دانشگاه صنعتی اصفهان به منظور تعیین مناسب ترین تیمار بذری و ارزیابی اثر پرایمینگ بر روی سه رقم گلرنگ تحت سه رژیم آبیاری انجام گرفت. برخی از مطالعات اثرات سودمند پرایمینگ بذر را بر روی گیاهان مختلف بررسی کرده اند اما در حال حاضر اطلاعات کمی در مورد خصوصیات مربوط به جوانه زنی، مراحل نموی، عملکرد و خصوصیات کمی و کیفی بذور تیمار شده ژنوتیپ های م...
Impacts of projected changes and variability in climatic data on major food crops yields in Rwanda
This paper investigated the response of major food crop yields namely beans,cassava, Irish potatoes, maize and sweet potatoes to ongoing changes in climate inRwanda. The projected daily precipitation and temperature data for the period2000-2050 used in this study were generated by stochastic weather generator(LARS-WG) from daily raw data for the period 1961 -2000. These data werecollected from ...
متن کاملEnsiling of crops for biogas production: effects on methane yield and total solids determination
BACKGROUND Ensiling is a common method of preserving energy crops for anaerobic digestion, and many scientific studies report that ensiling increases the methane yield. In this study, the ensiling process and the methane yields before and after ensiling were studied for four crop materials. RESULTS The changes in wet weight and total solids (TS) during ensiling were small and the loss of ener...
