in order to study on the effect of nitrogen, vermicompost and nitroxin biofertilizer on growth indices and phenology of sesame a field experiment was carried out at behbahan in summer of 2009. treatments were arranged in a factorial experiment based on rcbd with three replications. three rates of nitrogen fertilizer (50, 75 and 100% of region recommended nitrogen rate,) as a first factor, three...

canola (brassica napus l.) is one of the most important oil seed crops. in order to evaluate the effects of integrated fertilization (chemical, manure and biofertilizers) on canola (b. napus variety hyola 401) yield and uptake of mineral nutrients in saline soil and water, a field experiment was conducted in randomized complete blocks (rcbd) arrangement with eight treatments in three replicatio...

Effects of biofertilizers and stacosorb polymer* on yield and yield components of fennel (Foeniculum vulgare Mill.) under drought stress were evaluated using a split-factorial experiment based on a randomized complete block design (RCBD) with three replications at the agricultural research farm of Lorestan University, Khorramabad, Iran in 2013. The factors included drought condition (stressed a...

more nitrogen use efficiency in crops is important for maintaining and developing sustainable agriculture. in order to study the effect of different levels of mushroom compost and different resource of nitrogen on yield, yield attributes and nitrogen use efficiency of wheat (triticum aestivum l.), an experiment was conducted at faculty of agriculture, ferdowsi university of mashhad, iran, durin...

BACKGROUND: Nitrogen is a basic plant component, playing a decisive role in the intensification of plant production. Bio-fertilizers play a very significant role in improving soil fertility by fixing atmospheric nitrogen, both, in association with plant roots and without it, insoluble soil phosphates and produces plant growth substances in the soil. OBJECTIVES:</s...

to study the effects of biological and manure fertilizer on quantity and quality characteristics of roselle (hibiscus sabdariffa l.), an experiment was conducted as split plot based on a randomized complete block design with three replications at the agricultural research center of zabol university, iran during growing season of 2012-2013. treatments included three manure level; 0, 10 and 20 t....

to study the effect of different fertilization systems on forage quality and secondary metabolites ofmedicinal forage in additive intercropping of alfalfa and fennel an experiment was conducted as split plotbased on randomized complete block design with three replications at college of agriculture, shaheduniversity in tehran, 2011. the main plots were allocated to different levels biofertilizer...

introduction: soil fertility management is a key factor in achieving sustainable agriculture. use of organic fertilizers is one of the methods that without environmental harmful effects with improvement of chemical and biological conditions increases soil fertility. nitroxin contains a collection of the best strains of nitrogen fixation bacteria of the genus azospirillum and azotobacter. these ...

cultivation of high efficacy crops in resource utilization, especially with higher water and radiation use efficiencies is one of the important strategies to achieve the goals of sustainable agriculture. align with these guidelines and in order to estimate light extinction coefficient and radiation use efficiency of sesame a split plot arrangement of two factors based on randomized complete blo...
