Abstract

                                Field experiments were conducted during 1995-96 and 1996-97 to study the effect of phosphrous, bacterial culture inoculation and micro-nutreints on growth. nodulation and yield of chickpea in rice based cropping systems of Chhattisgarph plain region of Madhya Pradesh. Grain and straw yield and yield attributes of chicpea increased with increasing levels of phosphorus. All these characters were further increased with the inoculation of PSB (Phospate solubilizing Bacteria) over their respective levels of Phosphorous. Inoculation of rhizobium culture further enhanced the grain yield over their respective levels of phosphorus and PSB. Maximum per cent increase in grain yield of chickpea over TI (Control) was recorded under T12 (60 kg P205+ PSB+ RC + Seed treatment with Mo and FE) followed by T9 (60 kg P,O,+ PSB+ RC) and T6 (60 kg P.0. +PSB). Maximum impact of PSB and RC (34.1%) was observed with the application of 30 kg phosphorus (TS) and it decreased with increasing the levels of phosphorus.

Key words : Chickpea, PSB, Molybdenum, Iron, Yield
