Abstract

The present study is aimed to find out the effect of biofertilizers on performance of blackgram (Vigna mungo L.) , investigations were conducted at Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir, Shalimar, Srinagar during Kharif, 2009. The research material consisted of Black gram variety PU-19. the treatments consisted of combination of three levels of bio fertilizers viz., Rhizobium, PSB and Rhizobium +PSB, replicated three times in Randomized Block Design. The combined inoculation of Rhizobium + PSB slightly improved growth characters (plant height, dry matter production, number and weight of nodules per plant at maximum flowering) and the yield attributes(branches and pods per plant, seeds per pod, 1000 seed weight), than Rhizobium and PSB inoculated separately. Whereas a significant increase was recorded in straw yield with combined inoculation of Rhizobium + PSB over separate inoculations. Combined inoculation of Rhizobium + PSB proved beneficial for boosting seed yield of blackgram under temperate condition of Kashmir.
