Objective. To investigate the effect of seed treatment cultivated plants with complex bacterial preparation Azogran (based on Bacillus subtilis IMB B-7023 and Azotobacter vinelandii B-7076) initial stages ontogenesis under laboratory conditions. Methods. Microbiological (cultivation microorganisms was carried out periodic culture conditions — A. B-7076 in Ashby liquid digest medium, a mineral m...

in order to evaluate effect of azotobacter chroococcum strains on yield, yield components and qualitative indices of winter rapeseed (brassica napus l.), an experiment was conducted during 2009-2010 growing season at research institute of rice in rasht. the experimental design was completely randomized block, with three replications. investigated treatments were including control (without seed ...

introduction cultivated sunflower is one of the largest oilseed crops in the world. sunflower seed is the third largest source of vegetable oil worldwide, following soybean and canola. nitrogen is one of the most important elements for crops to achieve optimum yields and quality. phosphorus (p), next to nitrogen, is often the most limiting nutrient for crop and forage production. phosphorus ava...

Double inoculation of soybean with Bean pod mottle virus (BPMV), a member of the Genus Comovirus, Family Comoviridae, isolates V-S98-1 and V-S98-15, together with Soybean mosaic virus (SMV) a member of the Genus Potyvirus, Family Potyviridae) isolates 2K-38, S98-51 and S98-52, was compared to single inoculation with each of the isolates, on Hutcheson, Hutcheson Roundup Ready® (RR BC3) and Hutch...

introduction: use of unbalanced chemical fertilizers especially p, having low absorption efficiency and low solubility compounds with soil components, has resulted in the production and use of bio-fertilizers (17, 23 and 29). bio-fertilizer is a preservative material consisting of one or several specific beneficial micro-organisms or their metabolic products used to supply plant nutrients and d...

introduction fertilizers are the key components which provide plant nutrients' needs in recent years (omid jangir & sing, 1996; kapoor et al., 2007). in many cases, using chemical fertilizers has different negative environmental effects such as soil, water and air pollution, which increase environmental hazardous and production costs (jangir & sing, 1996; kapoor et al., 2007). biological activi...

in order to study the effects of integrated application of bio-fertilizer and chemical fertilizers on yield and yield components of corn, an experiment was conducted in 2008 in dezful city, (khoozestan province) in a factorial arrangement based on complete randomized block design with four replications. treatments were integrated application of biological and chemical fertilizers in four levels...

Given the hypothesis that co-inoculation with plant growth-promoting bacteria (PGPB) enhances beneficial effects of Rhizobium tropici greater mineral nutrition, optimizes biological nitrogen fixation and reduces use fertilizers in bean plants, objective this research was to evaluate synergistic associated Azospirillum brasilense, Bacillus subtilis, Pseudomonas fluorescens their combinations, on...

Fusarium head blight (FHB; scab) caused mainly by Fusarium graminearum is a devastating disease of wheat and barley around the world. FHB causes yield reductions and contamination of grain with trichothecene mycotoxins such as deoxynivalenol (DON) which are a major health concern for humans and animals. The objective of this research was to develop an easy seed or seedling inoculation assay, an...

The field experiment was conducted during Zaid season 2021-22 at Crop Research Farm, Department of Agronomy, Sam Higginbottom University Agriculture, Technology and Sciences, Prayagraj (U.P). soil the plot sandy loam in texture, nearly neutral reaction (pH 7.2), low organic carbon (0.48%), available N (171.48 kg/ha), P (13.6 kg/ha) K (215.4 kg/ha). treatments consisted three levels Gibberellic ...
