اثر کود بیولوژیک فسفره و کود شیمیایی فسفره بر خصوصیات مورفولوژیکی و فیزیولوژیکی لوبیا قرمزرقم صیاد

In order to evaluate the effect of solver microorganism of phosphorus and stay the effectiveness of biofertilizers and comparison of them to chemical fertilizer in bean crop in the country, a one - year experiment carried out in the field of cultural research and natural resources station of Boroujerd city. Sixteen treatments in three replications carried out as split plot experiment in random complete blocks in this experiment. Experimental treatments are: 1- treatment of phosphorus biological fertilizer in three types of phosphate biological fertilizer (fertile 2), Bio super phosphate biological fertilizer and MC1 biological fertilizer and control treatment without using of phosphorus biological fertilizer. 2- treatment of phosphorus chemical fertilizer (triple super phosphate) in four levels of 25%, and 50% and 75% and 100% in using fertilizers based on soil test. The results showed that using phosphorus biological fertilizer with optimum level of phosphorus chemical fertilizer and also the interaction effect phosphorus biological fertilizer and phosphorus chemical fertilizer have positive and significant effect on bush height, length of sheath, number of nod, biological yield and yield of bean, as in the studied zone, using the bio super phosphate biological fertilizer has the highest seed yield with yield of 412.20gr in square meter. And the highest seed yield belongs to using 100% phosphorus chemical fertilizer with yield of 462.93. Also in study the interaction effects of phosphorus biological fertilizer and phosphorus chemical fertilizer on seed yield. It is cleared that the highest seed yield belongs to using MC1 biological fertilizer and using 50% phosphorus chemical fertilizer with yield of 524.06. Finally we can recommend the using of MC1 biological fertilizer and phosphorus chemical fertilizer at level of 50% in bean crop in the studied zone.
