the nutrient elements uptake in many of soils, is a problem because of high ph and plenty of calcium ions in them. some of these elements are phosphorus and microelements. it is possible to increase absorption of these nutrient elements by addition of sulfur in soil and biological oxidation. the rate of this reaction is very slow and thiobacillus bacteria are the most important oxidators of sul...
BACKGROUND: Bio-fertilizers being essential components of organic farming play vital role in maintaining long term soil fertility and sustainability.OBJECTIVES: Study yield and growth indices of sorghum in response to consume chemical fertilizer and Nitroxin bio-fertilizer.METHODS: This research was conducted via split plot experime...
BACKGROUND: Fertilizer management plays an important role to achieve sustainable agriculture. OBJECTIVES: Current study was conducted to assess response of agrophysiological traits of wheat to apply different level of fertilizer and biologic fertilizer (Phosphorus and Nitrogen). METHODS: This research was carried out via factorial e...
This research was performed to study the effect of direct planting and transplanting of potato minituber on its yield and yield components. The experiment was designed as a randomized complete blocks with nine treatments and three replications. Treatments were one direct and eight indirect planting. In order to prepare the nursery, two types of pots (peat and nylon) and four types of substrates...
fusarium head blight (fhb) disease caused by fusarium graminearum is one of the most destructive diseases of wheat that in addition to the loss of product quality and quantity is able to produce the dangerous carcinogenic toxins in human and animals. in this study, the effects of different fertilizer treatments (vermicompost, chemical fertilizer and mycorrhiza) on performance components and exp...
In order to study of the effect of combined biologic and priming on growth characteristics and phosphorus (P) and potassium (K) concentrations in Nigella sativa L., an experiment was carried out in the greenhouse of Agriculture Faculty, University of Birjand with factorial CRD statistical design in 2011. Factors were 1- Bacteria treatments a (Pseudomonas sp 168), b (Pseudomonas sp 187), c (comp...

BACKGROUND: Management of water deficit is a great factor to sustainable crop production, especially in arid and semi-arid regions. Vermicompost is an organic compound that is microbial active and rich in nutrients that results from the interaction of earthworms and microorganisms with organic matter decomposition. OBJECTIVES: This research was carried out to ...
to study the effects of different fertilizing systems using green manure and zeoponix on grain yield and its components in sunflower, an experiment was conducted at the research farm of collage of agriculture, tarbiat modares university in 2010 and 2011. the experimental treatments were arranged as split plot design on the base of a complete randomized block design with three replications. two ...
