low nitrogen (n) use efficiency is considered to be one of the major problems in wheat production fields all over the world. this experiment was conducted to evaluate the effects of nitrification inhibitor (ni) 3, 4- dimethylpyrazole phosphate (dmpp) on the yield and nitrogen use efficiency of spring wheat (triticum aestivum l.) cv. bahar during 2011 at shahrekord university. a factorial experi...

This study setout to investigate the effect of wheat residue, tillage, and nitrogen fertilizer management on some agronomic traits of soybean as a split split plot based on randomized complete block design with three replications. The main plots included wheat residue management: collecting and leaving residue and sub plot included tillage (without tillage and conventional tillage), and the sub...

Effects of organic manure (poultry manure) applied alone and integrated with inorganic fertilizer (urea) on yield and yield component, N-uptake and soil fertility in wheat-maize cropping system was evaluated in a field experiment at Nuclear Institute for Food and Agriculture, Peshawar, Pakistan. Poultry manure was applied alone and were integrated in different proportions with mineral nitrogeno...

Appropriate fertilization practice is crucial to achieve maximum wheat grain yield with minimum nitrogen (N) loss. A field 15N micro-plot experiment was conducted to determine the effects of application methods [split application (SA) and band application (BA)] and N rates (60, 150 and 240 kg ha-1) on the wheat grain yield, urea-15N fate and N efficiency in Jiangyan County, China. At high N rat...

residue management has a direct impact on soil physical and chemical characteristics which in turn have identical effects on sustainability of crop production in agroecosystems. the effects of wheat residual management practices (burning, plowing under and removal) on soil physical and chemical characteristics were investigated in this research. treatments were compared in a complete block desi...

in order to evaluate the effect of nitrogen (n) and seeding rate and presence of rapeseed residues on yield and yield components of wheat, a field experiment was conducted in cropping year 2011- 12 at college of agriculture, shiraz university (badjgah), shiraz, iran as split-split plot arranged in randomized complete blocks design with three replications. treatment included presence and absence...

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 ...

Wheat (Triticum aestivum L.) variety mixtures represent a relatively unexplored avenue for maintaining yield and improving flour quality. A field experiment was conducted to examine the responses of three spring wheat varieties in pure variety and in variety mixtures under continuous cropping in Northeast China. Three modern spring wheat varieties, along with a three-variety mixture and a t...

plant growth regulators (pgrs) are widely used for lodging control in winter wheat (triticum aestivum l.) grown at high n rates. although the introduction of semi-dwarf wheat cultivars had largely solved the problem of lodging, evidence was already accumu-lating that the timely application of a growth retardant such as chlormequat (ccc) or ethephon could increase the grain yield of wheat, by th...
