Effect of Rhizobium Strains and Biofertilizers on Foot, Root Rot and Yield of Bush Bean in Sclerotinia sclerotiorum Infested Soil

Abstract

A glasshouse experiment was carried out to find out the effect of Rhizobium strains and biofertilizers on foot and root rot (Sclerotinia sclerotiorum) and yield of Bush bean. Six Rhizobium strains and three biofertilizers were used for seed treatment. Rhizobium strains (BINAR P36 and BINAR P6) and BINA biofertilizer resulted maximum reduction of seed rot, and foot and root rot of Bush bean in pot. In addition, these treatments increased germination, plant stand, shoot length/plant, root length/plant, shoot weight/plant, root weight/plant, vigour index, plant height, number of green pods/plant, weight of green pods/plant, weight of seeds/plant and healthy looking seeds in pot trials. Among them Rhizobium strains (BINAR P36) showed best performance. Key words: Rhizobium, biofertilizer, foot and root rot, Sclerotinia sclerotiorum, yield, Bush bean.   DOI:10.3329/jbs.v16i0.3744 J. bio-sci. 16: 73-78, 2008
