in order to study the effects of plant density and nitrogen rates on yield, nitrate and protein of silage maize (ksc 704) in shahrekord area, an experiment was conducted during 2007 growing season at the agricultural research farm of shahrekord university. the experimental design of the experiment was randomized complete blocks with factorial arrangement with four replications. treatment consis...

The present study were carried out in the Department of Genetics and Plant Breeding, Faculty of Agriculture, NDUAT, Faizabad during rabi season 2014-15 and 2015-16 entitled “standardization of biofortification and hydropriming for enhance seed yield and its quality parameters in chickpea (Cicer arietinum l.)” The objective of the study was assessing the comparative performance of yield and qual...

in order to study the effect of irrigation interval, n fertilizer and superabsorbent on yield and qualitative traits of sesame (sesamum indicum l.), a split-split-plot experiment was coducted in a farm in khusf of birjand, iran in 2009 on the basis of a randomized complete block design. the main plot was devoted to irrigation interval at three levels of 6, 12 and 18 days, the sub-plot was devot...

A study was conducted to investigate the effect of different planting densities and nitrogen doses on essential oil content and yield in herb and leaves of basil (Ocimum basilicum L.). The research was conducted during 2007 and 2008 using split-plot randomized complete block design with four replications. The experiment consisted of four plant densities (30×20, 40×20 and 50×20 cm) as the main p...

abstract lowland rice (oryza sativa l.) in south asia is under stress, as nitrogen removals by crops are higher than their replenishment through fertilizers. limited information is available on optimizing nitrogen dose in lowland rice to turn out higher yield. the present investigation aimed to optimize nitrogen fertilization and it’s response to the growth and yield of lowland rice. we evaluat...

Objective: A field experiment was conducted in order to study the effect of phosphorus and manure application on agronomic performance and seed yield of groundnut. Methods: Factorial combination of two groundnut varieties (‘Werer 962’ and ‘Oldhale’), Three rates of phosphorus (0, 90 and 180 kg P2O5 ha-1) and three rates of manur...

to study the effects of plant density and nitrogen rates on the ability of canola (regent  cobra; an inbred variety) to compete with weeds, an experiment was conducted as a factorial complete block design with four replications. the treatments included four levels of plant density at 150, 190, 230, and 270 plants m-2, and four levels of nitrogen (n) fertil-izer at 0, 46, 92, and 138 kg ha–1. r...

nitrogen is one of the most limiting nutrients for cereal production in many parts of iran. the effects of crop residue incorporation [0 (control), 25 and 50% of wheat (triticum aestivum l.)] and nitrogen (n) levels (0, 150, and 300 kg ha-1) on corn (zea mays l.) grain yield and nitrogen use efficiency were investigated at agricultural research station, shiraz university, shiraz, iran for two y...
