Abstract: Chickpea (Cicer arietinum L.) is one of the most important pulse crops in India. The crop is grown in Western Maharashtra mainly in Rabbi season. The chickpea is severely attacked by Rhizoctonia bataticola (R.bataticola). Organic amendments, such as neem, soybean, castor, safflower, groundnut cakes and vermicompost, compost, FYM, gypsum, poultry manure were applied to chickpea, which was reduce the incidence and survival of R. bataticola. Many of these amendments reduced pathogen population. The lowest R.bataticola population was observed in neem cake treatment (4.5 x 10-3 /g) followed by castor cake (6 x 10-3 /g) and cotton cake (8 x 10-3 /g) as compared to control (30.5 x 10-3 /g).In case of organic amendment level assessment it observed that as level increases the population of microbe’s decreases. Least incidence of Rhizoctonia root rot was observed in neem cake treatment (0-10%) followed by gypsum and poultry (5-10%) at different growth stages as compared to control (70%) Groundnut cake (15-40%) and safflower cake (25-35%) showed least adverse effect over incidence Rhizoctonia rot of chickpea.
