Drought stress is one of the abiotic factors that reduces crop production. The use of biofertilizers can mitigate the negative effects of drought stress and reduce chemical inputs on agricultural systems. In order to investigate the effect of combined management of chemical and biological fertilizers on yield and quality-related traits of black cumin (Nigella sativa L.) under different irrigati...
Fertilizer management is essential for achieving sustainable agriculture and protecting the environment. To evaluate the effect of Nitroxin bio-fertilizer application on quantitative and qualitative traits of corn hybrids a farm research was arranged via split plot experiment based on the randomized complete block design with four replications in 2013. Main plots were Included: use of the chemi...
In order to study the effect of phosphate biofertilizer and chemical fertilizers of nitrogen, phosphorus and sulfur on some growth and yield components of Camelina sativa L., a study was conducted based on a factorial experiment; this was done in a randomized complete block design with three replications at Kazeroon during the 2016 growing season. Treatments included bio-based phosphorus (P)...
A highly effective biological fertilizer (bio-fertilizer) can be produced cheaply in countries that have a source of a suitable type of zeolitic rock (tuff). Such rocks occur worldwide in areas of past or current volcanism. In the event of explosive volcanic activity huge volumes of silicic glass and other debris are projected into the atmosphere. Reaching high altitude the fine material is sep...
In order to evaluate the effect of arbuscular mycorrhizal (AM) fungi and Pseudomonas fluorescens bacteria on phosphorus fertilizer use efficiency, mycorrhizal dependence and grain yield and dry matter yield of maize under water deficit conditions, a field experiment was conducted as split-split plot arrangement based on randomized complete block design with three replications. The treatments in...
In order to study the effect of application of nitrogen, phosphorus and biologic fertilizers on yield and yield components of native bean, an experiment was conducted as factorial in randomized complete block design with three replications in Lahijan, northern Iran in 2013. Treatments consisted of chemical nitrogen fertilizer (0, 60 and 120 kg ha-1 urea), chemical phosphorus fertilizer (0, 40 a...
Compost is the product resulting from the controlled biological decomposition of organic material that has been sanitized through the generation of heat and stabilized to the point that it is beneficial to plant growth. Compost bears little physical resemblance to the raw material from which it originated. Compost is an organic matter resource that has the unique ability to improve the chemical...
chemical fertilizers are threat in hman life and today application of biological fertilizer find more important. this study performed in order to evaluate the effects application of biofertilizers with urea fertilizer on yield, protein percentage and numbers of eyes in plant, plant height and chlorophyll spad in potato var. marphona. a factorial experiment was conducted based on randomized comp...
in order to evaluate of biological fertilizers and micronutrient elements effects on yield and some agronomic traits in rapeseed (brassica napus l.), an experimental was performed as factorial arrengement based on randomized complete blocks design with three replications in 2012-13 in research station of shahid chamran university of ahvaz, iran. in this experiment, micronutrient elements were i...
Reduction of chemical fertilizer consumption in the production of agricultural products, using bio-fertilizers as a suitable substitution or complementary for chemical fertilizers has privileges from ecology and economical aspects. The advantages of applying of bio-fertilizer are providing plant with different nutrients in accordance to the natural ability of plant, enhancing and improving soil...
