Abstract:
In order to study effect of biological fertilizers on vegetative characteristics, dry matter and yield of corn, a factorial experiment in randomized complete block design with three replications was conducted in the city of dareshahr in 2010. Biological factors examined include 4 levels of nitrogen fertilizer (nitroxin, nitrokara, super nitroplas and control) and 4 levels of biological phosphorus fertilizer (biophosphore, phosphate fertilized 2, mc1 and control), respectively. Results showed that biological nitrogen and phosphorus fertilizers on all traits (stem diameter, stem height and dry matter) had a significant impact. About of biological nitrogen fertilizer, the highest dry matter intake of 17961 kg/ ha super Nitroplas respectively, which increased 41% compared to control. About of biological phosphore fertilizer, the highest dry matter intake of 17961 kg /ha with the consumption phosphore 2 fertilizer respectively, which increased 41% compared to control. The survey results showed that the use of biological fertilizers, dry matter of corn through improved vegetative characteristics (stem diameter and stem height) increases.
