The objective of this study was to examine the impact of starter nitrogen fertilizer on soybean root activity, leaf photosynthesis, grain yield and their relationship. To achieve this objective, field experiments were conducted in 2013 and 2014, using a randomized complete block design, with three replications. Nitrogen was applied at planting at rates of 0, 25, 50, and 75 kg N ha-1. In both ye...

to investigate the effect of wild mustard plant density and nitrogen fertilizer on morphological characters, yield and yield components of canola a split-plot experiment based on a randomized complete block design with 3 replications was carried out in bu-ali sina university of hamedan, in 2009. 4 levels of nitrogen fertilization (100, 150, 200 and 250 kgn h-1) were assigned to main-plots and p...

Sorghum (Sorghum bicolor (L.) Moench) is the fifth important cereal crop after wheat (Triticum aestivum L.), maize (Zea mays L.), rice (Oryza sativa L.), and barley (Hordeum vulgare L.) in the world. It is cultivated in about 46 million ha with a total production of 62 million t (FAO 1998). Asia and Africa account 86% of the total area under sorghum, but their contribution towards total product...

in order to study the effect of nitrogen level on physiological characteristics, grain yield and yield components of tetraploid wheat genotypes, a split plot randomized complete block design field experiment with three replications was conducted in 2007 at research farm of isfahan university of technology. four levels of nitrogen fertilizer (20, 80, 140 and 200 kg/ha) were chosen as main plots ...

in other to evaluate grain yield, rate and effective grain filling period of four barley (hordeum vulgaris l.) cultivars in different planting dates, a factorial experiment based on a randomized complete block design was conducted in the islamic azad university of ardabil research station in 2009. the treatments applied were: three levels of different planting dates (september, 23; october, 16 ...

The study was carried out for two consecutive years (2005-06 to 2006-07) to evaluate the wheat response to five different levels (0, 4, 8, 12 and 16 kg ha) of manganese (Mn) alongwith 150-100-60 kg NPK ha application. The experiment was laid out in randomized complete block design (RCBD) with three repeats under irrigated conditions at Agriculture Research Farm Karor, District Layyah. NPK was a...

A field experiment was conducted during kharif season of 2013 to find out the effect of ecofriendly modified urea materialsunder aerobic and puddled rice cultivation on growth andyield of rice at College Farm, PJTSAU. The results revealed with application of natural nitrification inhibitors (NNI)significantly improved plant growth parameters and inturn grain yield over prilled urea (PU)in both ...
