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 کاملuse of spectral reflectance values for determining nitrogen, phosphorus, and potassium contents of rangeland plants
this study was carried out to determine nitrogen, phosphorus, and potassium contents of rangeland plants using spectral reflectance value. the measurements were made in 1 m2 area of different parts of a rangeland. a portable spectroradiometer capable of measuring the wavelength range of 325-1,075 nm of the electromagnetic spectrum was used to collect spectral data. spectral measurements were ma...
متن کاملEvaluation of Yield, Nitrogen Use Efficiency and Radiation Use Efficiency of Wild Majoram in Response to Organic and Chemical Fertilizers
In order to investigate the effect of urea and Azocompost on economic yield, nitrogen use efficiency (NUE) and radiation use efficiency (RUE) of wild majoram, a factorial experiment was conducted based on randomized complete block design with three replications at Yazd and Mashhad, Iran, during 2012-2013 growing season. Four urea levels and four Azocompost levels (to provide 0, 40, 80 and 120 k...

متن کاملEffect of phosphorus on arsenic uptake and metabolism in rice cultivars differing in phosphorus use efficiency and response.
A hydroponic experiment was carried out to investigate the effect of phosphorus (P) nutrition on arsenic (As) uptake and translocation within the seedlings of rice cultivars. The experiment occurred in three stages: I 5 days of acclimatization (nutritive solution); II 10 days under P (0.0 and 0.09 mM) and As (0.0 and 100 mM) treatments; III 5 days under recovery. The As exposure had significant...
