Wastewater from the sweet potato starch industry is a large source of nutrient-rich substrates. We assessed whether this wastewater could be used to produce Paenibacillus polymyxa biofertilizer for foliar application to tea trees. Using the central composite design methods we experientially determined that the optimal culture conditions for P. polymyxa were pH, 6.5; temperature, 29.0 °C; and in...

introduction canola is the world third oil crop with 25 to 55 percent oil content (hezbavi & minaei, 2008). in recent years, tendency towards expansion of the acreage of canola in iran has been increasing and for the years 2010-2011 an area of 93000 ha with a total production of 190000 tons has been reported (ministry of jihad of agriculture, 2013). application of biological fertilizers which a...

BACKGROUND: Vermicompost in sustainable agriculture is very useful for improving soil porosity and thereby providing more nutrients to crop. OBJECTIVES: Current research was conducted to evaluate effect of biofertilizer (vermicompost) under different level of irrigation on crop production and protein yield. METHODS: This study was c...

Two field experiments were carried out during the winter seasons of 2000/2001 and 2001/2002 at the Agricultural Experimental Station (at Abeis) Alexandria University, to investigate the response of globe artichoke plants cv. French, to the inoculation with Halex2 and Microbein biofertilizers under varying N levels (0, 45, 90 and 135 kg N fed -1 ). The results indicated that increasing N applied...

BACKGROUND: Bio-fertilizers are best eco-friendly approach for plant and soil environment. Also, micronutrient element such as iron plays a key role in the formation of chlorophyll and photosynthesis. OBJECTIVES: This study evaluated the effect of growth bacteria and Nano iron fertilizer and ordinary iron fertilizer on some physiological properties of Tritical...

objective: many agronomic practices may need to be adjusted to maximize yield and quality of sugar beet. thus agronomic package must be always modified. this sutdy was laid out for evaluation of changes in carbohydrates and sugar yield in sugar beet (beta vulgaris l.) under different biofertilizers and irrigation closed time at dorud region of iran, during 2013. methods: the experimental design...

introduction safflower) carthamus tinctorius l.) is a tolerant plant to water deficit due to long roots and capability for high water absorption from soil deeper parts. safflower can growth successfully in regions with low soil fertility and temperature. behdani and mosavifar (2011) reported that drought stress affect on yield by reducing yield components and agronomic traits. biofertilizer dur...

This experiment was lay out in order to evaluate the effects of different biofertilizers on seed yield, protein and oil of rapeseed in Iran. The experiment was a factorial design with three replications. Treatments were four nitrogen biofrtilizers (control (N1), Nitroksin (N2), Azotobacter (N3) and Supernitroplat (N4)) and three phosphate biofrtilizer...
