Abstract

The variety 012Rof p.vulgaris was inoculation with two important strains of rhizobium bacteria namely USDA-2674 & USDA-2669 and a local strain ENRRI-2in addition to starter dose of 20/kg/n/ha.the inoculation seeds were sown the Shambat Research farm with objective of selecting the most efficient strain.
the USDA-2674 strain gave increased yield in Shambat Research. the application of the nitrogen fertilizer with inoculation resulted in increasing the dry matter weight. High dose of 120/kg/n/ha proved to be of adverse effect on symbiosis in addition to the high cost.
