A field experiment was conducted to study the impact of Sulphur(S) and Phosphorus (P) on yield, nutrient status of soil and their contents in pigeonpea (Cajanus cajan) during the year 2008-2009. Seven treatments were studied in Factorial Randomized Block Design with three replications. The treatment combinations were derived from three levels of sulphur (0, 20 and 40 kg S ha(-1)) and four level...

Nitrogen fertilizer is an important kinetic energy for potato production. To study the effect of nitrogen(N) application and topdressing ratio on growth yield, different N levels: N75 (75 kg ha−1), N150 (150 N225 (225 ha−1) base/topdressing ratios: T1 (2:8), T2 (5:5), T3 (8:2), T4 (10:0) were used to find best operation. The results showed that higher yields can be obtained when 120–180 ha−1 wa...

Purpose. To study of yield formation and protein content in the grain different ripening varieties soft winter wheat under condition using various types doses fertilizers. Methods. Field laboratory (determination content), calculation (collection protein), mathematical statistical. Results. It was found that fertilization systems reliably increased wheat. The use N75 this indicator by 1.2 times...

this study was performed to assess the effects of nitrogen fertilizer and vermicompost on qualitative and quantitative yield of chamomile ( matricaria chamomilla l.). it was conducted at the research fields of ran company located in firouzkouh, iran, in 2013. treatments were consisted of 1) control, 2) 100% nitrogen from urea, 3) 100% nitrogen from ammonium nitrate, 4) 75% nitrogen from urea an...

Field and laboratory experiments were conducted to assess the response of wheat external auxin application nitrogen. Studied factors in field experiment different concentrations (0, 50, 100 ppm) nitrogen fertilizer 75, 150 kg/ha). In experiment, germination traits produced seeds from maternal plants under treatments assessed. Results showed that no with had higher stem leaf yield than 50 ppm kg...

in many crops, incorrect management of nitrogen and water is one of the most important factors in the resources productivity such as water and nitrogen. in order to evaluate the effects of different nitrogen levels (zero, 50, 100 and 150 kg ha-1) and irrigation application rates (100, 75 and 50% of water requirement per species) on corn, sesame and sugar beet, three separate experiments was con...
