Comparing the Efficiency of Nitrogen and Phosphorus Bio-fertilizers on Quality and Quantity Yield of Pishtaz Wheat Cultivar

In order to evaluate the effect of nitrogen and phosphorus bio-fertilizer on quality and quantity characteristics of Pishtaz cultivar wheat, a factorial experiment was carried out in a randomized complete block design with three replications in 2013- 2014 at Lorestan province. Factors include 4 levels of biological nitrogen fertilizer (Nitroxin, Nitro Kara, Supernitroplus and control) and 4 levels of biological phosphate fertilizer (bio-phosphorus, phosphate fertilizer, phosphate to grow and control). The results showed that the maximum amount of grain yield, biological yield, grain carbohydrates content and protein content with 568 grams per square meter, 1329.2 grams per square meter, 73% and 13%, respectively belonged to Supernitroplus treatment. Sources of phosphorus bio-fertilizers increased the amount of these traits compare to control treatment. In resources of phosphate bio-fertilizers the maximum amount of biological yield by 1325.2 grams per square meter was obtained in phosphate to grow treatment that increased the 40% compared to control. Biological yield differences in this treatment with control treatment were significant at the 1% probability level. Overall the results of this study showed that application of phosphate bio-fertilizer by Supernitroplus caused improving yield components and finally improving the quality and quantity of wheat compared to control treatment.
