Abstract
Extract of organic matter was used with Rhizobium legume inoculums and without it , and other compositions treatments from organic matter and NP- fertilizer ( control , 100%NP (160+160-NP 27-27% ) 1.5%C + NP50%, and 1.5%C) in tow calcareous soils (18% , 31% -CaCO3) to study the treatments role in infection achievement and growth and yield of plant. The treatments were carried out in the pot experiment 2009-2010agriculture season.
The results indicated a significant increase in emergency percentage 95% with treatment C1.5%-C + NP50% + R. legume inoculum - 18% CaCO3), which recorded the best results for the characterization of plant and contents , roots nodule numbers included in two growth stages(50 ,53 nodule/plant) and 8 branches numbers ,98 cm height of plant , 51 gm/plant yield and beast contents. in addition of soil contents from N,P , and total microbial content. The treatment saved50% of fertilizer recommended of N,P through the content of the treatment and added microbial activity which improved the performance of calcareous soils.
