Effect of calcium carbonate and organic mater in Rhizobium lequme inoculums activity and their effect in lequme growth and yield
ANBAR JOURNAL OF AGRICULTURAL SCIENCES,

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.
