Integrated effect of bio fertilizers, organic manures and inorganic fertilizers on growth & yield of chickpea

A field experiment was conducted on vertisols of Agricultural Research Station, Amaravathi, Guntur dt, Andhra Pradesh during rabi of 2017-18 & 2018-19 to find out the influence of bio fertilizers and organic manures on growth and yield of chickpea. A desi variety JG-11 was grown in Rabi in Krishna zone. All six treatments were randomly allocated and replicated thrice in a randomized block design The results of the study indicates that even though soil pH, EC not significantly varied, significant variation in yield is attributed to the increased uptake of N and P. Application of bio fertilizers influenced the dry matter accumulation at all growth stages and yield of chickpea. Higher dry matter accumulation and yield of chickpea was recorded with 100 % RDF (20:50:0:40) followed by 50% RDF + vermicompost@2.5 t ha-1 + Rhizobium + PSB @2kg ha-1 applied to chickpea during both the years of experimentation. Proliferation of microbial population was observed in organic manure treated plots.
