Evaluation of Nitrogen Fertilizer on Yield and Yield Components of Bread and Durum Wheat Genotypes
The present study aimed at investigating the effect of different levels of nitrogen on yield and yield components of bread and durum wheat. To this end the experiment was conducted in 2010-2011 in south west of Iran as split plots based on randomized complete block design with three replications. Main plot included four levels of nitrogen 60, 120, 180, 240 kg.ha-1 and the sub plot included four...
متن کاملNitrogen 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 کاملDepth of nitrogen fertiliser placement affects nitrogen accumulation, translocation and nitrate-nitrogen content in soil of rainfed wheat
A field experiment was conducted to examine the effects of different depths ofnitrogen (N) fertiliser placements on N accumulation, remobilisation and NO3−-Ncontent in soil of rainfed wheat. Nitrogen was applied on the surface (D1) and inthe 10 cm (D2), 20 cm (D3) and 30 cm (D4) soil layers from 2010 to 2012.Compared with D1 and D2, D3 and D4 treatments obtained significant higher Ndistribution...
متن کاملEffects of manure nitrogen on vegetables’ yield and nitrogen efficiency in Tanzania
Due to an increasing demand of leaf vegetables, and hence their economic importance in the tropics, it is very common that excessive fertilizer N rates are applied to vegetable gardens and fields to attain high yield. This calls for more information on their nutrient requirements. In this study, we designed experiments to explore the effect of organic N levels on the yield and agronomic N use e...
