Effect of different organic amendment on population dynamics and incidence of Fusarium Wilt in chick pea

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 Fusaruim oxysporium f. sp. ciceri (F. oxysporum f.sp. ciceri). 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 survival and incidence of F. oxysporum f.sp. ciceri. Among above amendments reduced pathogen population. The population of F. oxysporium f. sp. ciceri was least in neem cake (4 x 10-3 /g) followed by cotton and castor cakes and the highest in control followed by groundnut (22 x 10-3 /g), safflower (21 x 10-3 /g) cakes. Chickpea wilt disease were the lowest observed in neem cake treatment (0-10%) and the highest in control (70%) followed by groundnut (25-35%) and soybean (25%) cakes.
