a consortium of biofertilizers (azotobacter chroococcum and bacillus subtilis) was applied in conventional as well as organic matrix entrapped granular forms as sole nutrient source in two different doses for cultivation of wheat (triticum aestivum l. cv. pbw-343). a double dose of conventional biofertilizers increased the growth of wheat plants as measured on 30, 60, 90, and 120 days after sow...
in order to evaluate the effect of balanced application of chemical phosphorus fertilizer and seed inoculation with phosphate solubilizing bacterium and arbuscular mycorrhizal fungus and on the yield and yield components of maize (zea mays l.) under normal and limited irrigation conditions, a split-split plots arrangement based on randomized complete block design with three replications was con...
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...
introduction savory (satureja hortensis l.) is an annual herbaceous plant that belongs to the lamiaceae family. nowadays, the use of biofertilizers is increased in agriculture and their role in increasing the crops production has been demonstrated in many research works (vessey, 2003; chen, 2006; mahfouz & sharaf- eldin, 2007). one of the most important visions is sustainable production of enou...
in order to reduce consumption of chemical fertilizers and in order to evaluate the effect of biofertilizers on yield and yield components of sunflower nuts (helianthus annuus l.), the research was carried out with using factorial based randomized complete block design with three replications at agriculture and natural resources researches station of khoy in 2011. the first factor was three su...
Global warming and climate change are the most potent cause of natural disasters like droughts, high temperature, extreme cold in some places, rising ocean level. One important these poor cropping patterns extensive use agrochemicals. These chemical fertilizers increase level salts soil also make acidic.
