Effect of cover crops and application of nitrogen fertilizer on tuber yield and nitrogen use efficiency of potato (Solanum tuberosum L. cv. Sante)
Inclusion of cover crops in crop rotations has several benefits such as supplying nitrogen for the next crop. To investigate the effect of cover crops and different levels of nitrogen fertilizer on tuber yield, yield components, and different nitrogen efficiency indices of potato, a filed experiment was conducted as split plots arrangements in randomized complete block design with three replica...
متن کاملInvestigation of Rate and Method of Nitrogen Application on Nitrogen Use Efficiency and Seed Yield of Safflower (Carthamus tinctorius L.)
Nitrogen fertilizer management has a special priority for safflower economic production. Increasing the efficiency of this element, in addition to increasing economic benefits, also reduces environmental pollution. Therefore, a factorial experiment was conducted in the form of statistical design of complete randomized blocks with three replications at Safiabad Agricultural and Natural Resources...
متن کاملOptimizing nitrogen application rate and plant density for improving cotton yield and nitrogen use efficiency in the North China Plain
Plant population density (PPD) and nitrogen (N) application rate (NAR) are two controllable factors in cotton production. We conducted field experiments to investigate the effects of PPD, NAR and their interaction (PPD × NAR) on yield, N uptake and N use efficiency (NUE) of cotton using a split-plot design in the North China Plain during 2013 and 2014. The main plots were PPDs (plants m-2) of 3...

متن کاملThe Effects of Different Concentrations of Nitrogen Sources on Growth of Micropropagated Potato Cultivars
The use of nitrogen in nutrient media is essential for growth and helps identify highly productive media for potato (Solanum tuberosum L.) micropropagation and adventitious shoot formation. Three potato cultivars (Agria, Marfona and Savalan cultivars) were examined for their growth response with medium containing four different levels of KNO3 (1, 1.25, 1.5 and 1.75 times as much 1.9 g l-1) and ...
