effect 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...
Crop Rotation Effects on Soil Microbial Populations, Biomass and Diversity under Wheat in a Brown Loam
The inclusion of grain and green manure (GM) or forage legumes in cereal production systems on the Prairies does improve the fertility and quality of soils (Wright 1990; Campbell et al. 1992; Green and Biederbeck 1995; Biederbeck et al. 1998). Legume-based cropping systems can also reduce nitrogen losses and greatly increase the proportion of crop residuecarbon that is sequestered in stable soi...
متن کاملIntegrative impacts of soil tillage on crop yield, N use efficiency and greenhouse gas emission in wheat-corn cropping system
Wheat-corn cropping system is one of the most important grain production systems in theworld. However, the integrative impacts of soil tillage on crop yield, N use efficiency (NUE)and greenhouse gases (GHGS) emissions are not well documented in this system. Thus, a twoyear field experiment was carried out in a typical wheat-corn cropping system with four tillageregimes during the wheat season, ...
متن کاملDoes agricultural crop diversity enhance soil microbial biomass and organic matter dynamics? A meta-analysis.
Our increasing dependence on a small number of agricultural crops, such as corn, is leading to reductions in agricultural biodiversity. Reductions in the number of crops in rotation or the replacement of rotations by monocultures are responsible for this loss of biodiversity. The belowground implications of simplifying agricultural plant communities remain unresolved; however, agroecosystem sus...
متن کاملSimulated yield and profitability of five potential crops for intensifying the dryland wheat-fallow production system
Greater precipitation use efficiency (PUE) and economic returns by increasing cropping frequency through the addition of summer crops to the dryland winter wheat-fallow (WF) cropping system have been reported in the semiarid Central Great Plains of USA. However, due to the highly variable nature of precipitation and uncertain water availability, selection of a crop with assured positive net ret...
