Study of genetic diversity in bread wheat germplasm using nitrogen uptake and nitrogen use efficiency characteristics
In order to evaluate the traits related to nitrogen utilization and to identify the superior genotypes, 33 bread wheat landraces along three check cultivars of Chamran and Koohdasht (from Iran) and Gobustan (from the Republic of Azerbaijan) were studied in simple lattice statistical design with two replications under two treatments of non-usage and application of 200 kg/ha ammonium nitrate fert...
متن کاملthe effect of nitrogen rate on nitrogen use efficiency index in wheat (triticum aestivum l.) cultivars
in order to investigate the effects of different levels of nitrogen rate on yield and seed yield components of wheat cultivars, an experiment was conducted on araghi mahalleh (gorogan) research farm in 2008. treatments, nitrogen in the form of urea (0, 90, 180 and 270 kg/ha) and cultivars (tajan, falat and n81-18) were arranged as factorial based on randomized complete block design with four re...
متن کاملEfficiency of nitrogen fertilization in spring wheat
An assessment of the nitrogen fertilization efficiency should not only include quantitativeand qualitative yield changes, but also an analysis of formation some indicators such as: Nharvest index (NHI), N use efficiency (NUE), N utilization efficiency (NUtE), N agronomicefficiency (NAE), N physiological efficiency (NPE) and N apparent recovery fraction (NRF).The objective of the study was the e...
متن کاملDeconvoluting nitrogen use efficiency in wheat: A simulation study
Cereal producers are under pressure to increase yields and maintain profitability against a background of environmental constraints and high ertiliser costs. The production of high yields requires high inputs of N, and excessive N can lead to pollution of watercourses. This provides an ncentive for the maximisation of nitrogen use efficiency (NUE), defined as grain yield per unit available soil...
متن کاملwater use efficiency of four dryland wheat cultivars under different levels of nitrogen fertilization
it is suggested that cultivars of wheat (triticum aestivum l.) with regulated growth and development would be able to produce higher yields under water-limited conditions, which is crucial in future food production. water use efficiency (wue) is worthy of exploration in this regard. in this study, the effects of nitrogen fertilizer levels (0, 40 and 80 kg nha-1) and a plant growth retardant (ch...
