Abstract:

Biological fertilizers are natural inputs that can be applied in sustainable agriculture as an alternative to chemical fertilizers. In order to study the effect of biofertilizers on yield and yield components of corn, an experiment was conducted in factorial design based on randomized complete blocks with three replications in Eyvan, Ilam province, Iran 2011. Treatments were four levels of Nitrogen biofertilizer (nitroxyne, Nitrocara, supernitroplas and control) and four levels of phosphorus biofertilizer (biophosphate, phosphate fertilizer 2, phosphate fertilizer 3 and control). The results indicated that phosphorous and nitrogen biofertilizer levels had significant effect on all of studied traits. This result showed that with Nitroplas, stalk diameter, ear height, ear diameter and corn plant yield produced 3/16 cm, 112/47 cm, 6/21 cm, 11874 kg per hectar respectively and Nitrocara resulted in 198/3 cm plant height. Application of phosphate fertilizer 2, resulted in 190/8 cm, 2/95 cm, 108 cm, 5/59 cm and 11998 kg per hectar for plant height, ear diameter, ear diameter, ear height and yield respectively. Interaction between Nitrogen biofertilizer in phosphorus biofertilizer on kernel weight, cob diameter with phosphate fertilizer 2 + supernitroplas resulted in  414/88 gr and 7/16 cm respectively and phosphate fertilizer 2 + nitroxyne produced 27/1cm in ear length. In general, the result of this study showed that using various resources of biological Nitrogen and phosphorus fertilizer increase grain yield by improving yield components.
