a randomized complete block design with three replications was performed in rice research institute of iran, rasht in 2008, to find the effect of supplement foliar application of nitrogen and potassium on ’daylam‘ hybrid rice grain yield, its components and grain protein percentage. foliar application of 20 kg nitrogen (5 percent n) and 15 kg potassium (3 percent k2o) in different pre-anthesis ...
to evaluate the effect of various levels of nitrogen fertilizer on nitrogen use efficiency and grain yield of canola cultivars, a split plot experiment based on randomized complete block design was conducted in 2007. factors were: nitrogen fertilizer at four levels (zero, 50, 100 and 150 kg/ha) in the main plots and canola cultivars at three levels (‘clover’, ‘opera’ and ‘okape’) in the sub plo...
in order to evaluate the effects of nitrogen levels and its split application on growth indices and their relationship with grain yield of rice (cv. khazar), a field experiment was conducted at rice research institute of iran with 11 treatments arranged in a randomized complete block design with 3 replications in 2008. nitrogen fertilizer levels (10, 20 and 30 kg.ha-1) were applied according to...
Although the nitrogen nutrition index (NNI) is a widely used indicator of plant nitrogenstatus, no model of NNI calculation for spring barley (Hordeum vulgare) reflecting also specificmalting requirements on grain has been published. The aim of this study was to determinean optimal range of the nitrogen nutrition index (ratio of nitrogen concentration in shootbiomass to critical nitrogen concen...
Intercropping is one of the effective components of sustainable agriculture. In order to assess the effects of nitrogen application and planting arrangement on linseed and berseem clover leaf area, light absorption and their yield an experiment was conducted as a split plot based on randomized complete block design with three replications at the Research Farm of College of Agriculture, Isfahan ...
