Alkaline soils with low buffering capacity are susceptible to amendments such as biochar or biofertilizers, which could drastically alter their pH. For that, this study aimed evaluate the effectiveness of a and biofertilizer addition improve soil characteristics use nutrients reduce doses chemical fertilizer. we measured initial effect on characteristics. Then, changes produced by cultivated so...

in order to evaluate the effects of organic fertilizer complements application (aminol forte, fosnutren and kadostim) on grain yield, milling properties and nitrogen use efficiency of two rice (oryza sativa l.) cultivars, a field experiment in factorial layout and a randomized complete block design with 10 treatments and 3 replications was conducted at rice research institute of iran in 2009. t...

BACKGROUND AND PURPOSE Intensive agriculture is practised in Taiwan, and compost application is very popular as a means of improving the soil physical properties and supplying plant nutrition. We tested the potential of inoculation with thermotolerant microorganisms to shorten the maturity and improve the quality of biofertilizer prepared by composting. METHODS Thermotolerant microorganisms w...

in this study, the effect of irrigation regimes and plant nutrition were evaluated as split plot arrangment based on randomized complete block design with three replications in 2010. treatments consisted of irrigation regimes at three levels: well-irrigation, irrigation disruption at vegetative growth stage, and irrigation disruption at reproductive growth stage as main plots and combination of...

Biofertilizer can be used to replace chemical fertilizer so that soil quality is maintained and pollution avoided. The study aimed determine the effect of biofertilizers with different compositions microorganisms on growth maize plants. research was carried out in a greenhouse. Maize plants were fertilized by two kinds microorganisms. first biofertilizer contained Azotobacter sp, Azospirillum R...

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...

Farmers usually apply more chemical fertilizers to enhance the yield of strawberries in soilless culture. Humic substances and biofertilizers are now considered essential nutrient sources sustainable agriculture. The objective greenhouse experiment was observe effect humic fulvic acid (humic substances), biofertilizer on root growth, nitrogen (N) phosphor (P) growing media, populations N-fixing...
