Two sesame cultivars (Sesamum indicum L.) were evaluated using various 3 different sowing dates (20 th June, 10 th and 30 th July) and four nitrogen levels (0, 40, 80 and 120 kg N ha -1 ) at the New Developmental Farm of The University of Agriculture, Peshawar, Pakistan during summer 2012. The experiment was laid out in randomized complete block design (RCBD) with split plot arrangement using f...

In order to investigate the effect of urea, Azocompost and cutting on growth characteristics of Oregano, a factorial split-plot 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 kg N.ha-1 each) for Yazd location )0, 43.5, ...

in order to study on effect of plant density and nitrogen on yield and yield components of visia faba (faba bean), the experimental design was implemented by randomized complete block with three replications at 2010- 2011 in lahijan. the experimental factors were three plant density (25×25 cm, 35×35 cm and 45×45 cm) and four nitrogen fertilizer (0, 20, 40, 60 kg ha-1). in this experiment, featu...

The effects of nitrogen (N) addition on productive and physiological traits of Triticumdicoccum were assessed under two N levels (0, unfertilized, and 90 kg N ha−1) in fieldconditions, in two growing seasons. In the study case, the N supply (90 kg N ha−1) was appliedin three-split applications (20% at pre-plant stage, 40% at tillering stage, 40% at stemelongation). In unfertilized conditions, t...

the effect of nitrogen (n) levels on n uptake by high weed densities at early growth stages of corn (zea mays l., cv. double cross 370) was investigated for two years (2008-2009) at the agricultural research station of shiraz university. the experiment was arranged in a split-plot arrangement in the randomized complete blocks design with three replications. two levels of weed control (weedy and...

in order to study the competition effects of redroot pigweed (amaranthus retroflexus) and millet (panicum miliaceum) on maize performance under different rates of n fertilizer, a field experiment was conducted in 2009 in the research fields of tarbiat modares university in tehran as a randomized complete block design with factorial arrangement of treatments and three replications. accordingly, ...

The influence of inorganic fertilizer application on the flavonoid, phenol and steroid content of the leaves of Ocimum gratissimum and Gongronema latifolium was investigated. Cultivated O. gratissimum and G. latifolium were treated with NPK (15:15:15) inorganic fertilizer at 100 kg/ha, 200 kg/ha, 300 kg/ha, 400 kg/ha and 500 kg/ha treatment levels in plastic planting buckets derived using the f...

in order to investigate the effects of nitrogen fertilizer levels and intercropping ratios on yield and other morphological traits of two crops, field experiments were conducted during two years (2010-2011) in the research field of the school of agriculture, shiraz university, shiraz, iran. the study was carried out in a factorial experiment laid out based on a completely randomized block desig...

in order to investigate the effect of nitrogen fertilizer on tea yield and yield components in supplemental irrigation and rain fed conditions an experiment was conducted at feshalam tea research station in fouman (guilan) during (2008-2010). in this study, line-source irrigation technique and the strip plot experiment on randomized complete block design was used. six levels of nitrogen, zero, ...
