Using biological fertilizers and pesticides based on beneficial soil microbes in order to reduce mineral fertilizers and chemical pesticides in conventional agriculture is still a matter of debate. In this regard, a European research project seeks to elucidate the role of root-endophytic fungi and to develop molecular tools to trace and quantify these fungi in the rhizosphere and root tissue. T...

this research, for lowering the use of chemical fertilizer, was carried out using combinations of biological and chemical fertilizer on bean in rasht region in 2012 growing season. the experiment was conducted based on randomized complete blocks design with 12 treatments and three replications. experimental treatments included: control (no fertilizers and no inoculants), chemical fertilizers (n...

this experiment was conducted in 2012 at the research field of alborz research station, research institute of forests and rangelands, karaj, iran, to study the effect of chemical and biological fertilizers on sage (salvia officinalis l.) and replacing biofertilizers instead of high doses of chemical fertilizers. the experiment was conducted in factorial in the form of a randomized complete bloc...

The present investigation deals with the role of Plant Growth Promoting Rhizobacteria and chemical fertilizers alone or in combination on urease, invertase and phosphatase activities of rhizospheric soil and also on general impact on growth of safflower cvv. Thori and Saif-32. The PGPR (Azospirillum brasilense and Azotobacter vinelandii) were applied at 10cells/mL as seed inoculation prior to s...

Basil belongs to the Lamiaceae family, is one of the most important aromatic and medicinal plants, which it widely cultivated in many countries. The areal parts, especially leaves of sweet basil are widely used to enhance the flavor of foods such as salads, pasta, tomato products, vegetables, pizza, meat, soups, marine foods, confectioneries and other products. This study was conducted to inves...

iran is among the biggest emitters of greenhouse gasses in the world. agricultural sector has a remarkable role in non-renewable energy consumption and then, the environmental impacts in this country. in this regard, the environmental impacts of watermelon production as the most important melons produced in guilan province of iran were investigated through the life cycle assessment (lca) approa...

to evaluate the effects of fertilizing and deficit irrigation regimes on some chemical properties of soil and plant, an experiment was conducted during 2007 and 2008 growing seasons. experimental design was a split plot based on a randomized complete block design with four replications. the treatments consisted of three deficit irrigation regimes (main plots) and six soil fertilizing systems (s...

Plant diseases need to be controlled to maintain the quality and abundance of food, feed, and fiber produced by growers around the world. Different approaches may be used to prevent, mitigate or control plant diseases. Beyond good agronomic and horticultural practices, growers often rely heavily on chemical fertilizers and pesticides. Such inputs to agriculture have contributed significantly to...

The problems of chemical substance applications in different spheres of industry and agriculture and their effects on groundwater quality and human health are described. Sources of groundwater contamination from industrial and municipal wastes, agricultural pollutants, etc., are listed. The experience in the application of chemical fertilizers and pesticides in the USSR is described. A brief es...
