Nitrogen Fertilizer Effects on Soybean Growth, Yield, and Seed Composition
While previous research has been contradictory, potential grain yield responses and seed protein increases have led to con tinuing interest in N fertilizer application to soybean (Glycine max (L.) Merr.]. Field experiments were conducted at seven lo cations from 1990 to 1991 in Alabama to determine soybean response to N fertilization at various growth stages. Treatments included a factorial a...
متن کاملYield, Soil Nitrogen Uptake, and Nitrogen Fixation by Soybean from Four Maturity Groups Grown at Three Elevations
The exploitation of the soybe an [Glycine max (L.) Merr.] -Bradyrhizobium japonicum symbiosis in varied environments requires an understanding of factors that may affect fixed and soil N assimilation. Temperature affects both soybean maturity and N requirement, and soil N availability. Five soybean varieties belonging to four maturity groups (00, IV, VI, and VIII) and their respective nonnodula...
متن کاملsoybean (glycine max) yield and yield components responses to nitrogen supply and weather changes in the south-east of england
two year field experiment was carried out on two early maturing varieties of soybean (glycine max (l.) men.) bred in russia. the purpose was to investigate the possibility of production and to study the effects of nitrogen supply on soybean seed yield and yield components. a range of zero to 100 kg n ha in 1995 when plants suffered from water deficiency and zero to 100 kg n ha -1 in 1996 when p...
متن کاملShort communication Cucumber yield and nitrogen metabolism in response to nitrogen supply
Cucumber plants (Cucumis sativus L. cv. Brunex) were grown under controlled conditions in an experimental greenhouse and treated with four rates of N in the form of KNO3 (N1, 5 g/m ; N2, 10 g/m; N3, 20 g/m; and N4, 40 g/m). The intermediate N rates (N2 and N3) gave higher utilization of NO3 ÿ in the leaves (highest NR activities) than treatment N1 (inadequate) and N4 (excessive). This latter ra...
متن کاملyield and yield components reaction of soybean cultivars to inoculation by bradyrhizobium japonicum bacteria and nitrogen
some research indicates that n2 fixation in soybean cannot provide adequate nitrogen for proper yield. therefore, the effect of nitrogen and bradyrhizobium japonicum bacteria on some agronomic characteristics and quality of soybean cultivars was examined based on split plot in a randomized complete blocks design with three replications in 2012 at kerman township. treatments including control (w...
