: In order to study the effect of different nitrogen levels on yield components and seed yield of three barley cultivars, an experiment was conducted in 2011-2012 in a research farm of farming building of Islamic Azad University Khorasgan (Isfahan) Branch located in Khatunabad village (latitude 32o /40' N and Longitude 51o /48' E). A split plot layout within randomized com...
ABSTRACT- Declining land productivity associated with decreasing soil organic carbon and nutrients is a significant issue in monoculture production. The field experiment with different rates of fertilizer systems (60 kg ha-1 N + 100 kg ha-1 P, 300 kg ha-1 Bio-organic (organic fertilizer), 3 kg ha-1 Bioumik (biofertilizer), 30 kg ha-1 N + 50 kg ha-1 P + 150 kg ha-1 Bio-organic fertilizer and 30...
To investigate the effect of biofertilizers and N levels on yield and yield components of wheat, a two-year study (2012-2013) was carried out in Isfahan by using strip split plot based on randomized complete block design in three replications. Four treatments of biofertilizers (control, Nitroxin, Supernitroplus, and Vacosium seed plus) were assigned as vertical factor and four N levels (0, 25, ...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Background & Aim: In order study the effect of Thiobacillus, sulphur and organic materials on vegetative growth and essence production in lemon balm (Melissa officinalis L.) was conducted in pots in field condition at Shahrekord, Iran on 2008. Experimental: The factors were ten soil treatments inclusive 200 kg/ha sulphur, 400 kg/ha sulphur, 600 kg/ha sulphur, 200 kg/ha sulphu...
in order to increase grain yield, nitrogen use efficiency (nue) and nitrogen apparent recovery fraction (narf) in wheat (triticum aestivum l.), this experiment was carried out with 5 or 6 treatments and 3 or 4 replications in 14 locations at 22 different sites in iran during the 2004-05 growing season. the experiment was designed as a completely randomized block. the effect of n sources and tim...

Rapeseed needs a sufficient amount of nitrogen for optimal seed yield, but the efficiency of this plant in using nitrogenous (N) fertilizers is low, which causes an increase in N consumption in the cultivation of this plant. The need to maintain a high grain yield necessitates the use of a suitable timely program and manage the consumption of N fertilizers. Thus, a field experiment was conducte...
بادرشبی با نام علمی dracocephalummoldavica، گیاهی است نهاندانه، دولپه ای، پیوسته گلبرگ، از تیره نعناع. اسانس بادرشبی در صنایع داروسازی، آرایشی و بهداشتی، غذایی و عطر سازی کاربرد های فراوان دارد. به منظور بررسی اثر تیمار های کودی مختلف بر عملکرد و اسانس گیاه بادرشبی، این تحقیق در قالب طرح بلوک کامل تصادفی با سه تکرار انجام گرفت. تیمار ها شامل 1: شاهد. 2: (t/ha 100کود دامی). 3: (t/ha 50کود دامی +...
in drought stress condition, it is important to estimate the n and k requirement of sugar beet. a drought-tolerant sugar beet genotype, bp karaj, was evaluated in split plot factorial design based on a randomized complete block design with four replications at motahari research station, karaj, iran for three years. main plots were allocated to irrigation treatments including normal irrigation (...
