Abstract:

Chickpea, Cicer arietinum L., is one of the best legumes for human consumption and widely grown in India, and other parts of the world. Fusarium wilt caused by Fusarium oxysporum ciceri, is the most important disease of chickpea throughout the world and particularly in the India. The effect of 108 spore/ml of T.asperellum gave maximum (96.00 a) percentage of seed germination. In minipot trial, there were 25% increased of percentage of germination of seeds and shoot length but 27% increase of root length and 45% increase of vigour index in compare to control. In microplot trial, 75.25 % and 67.15 % crop protection respectively in two consecutive years were achieved by applying T asperellum. Similarly pulse yields and plant dry weight (25.9 & 30.12) were higher in compare with control and than both F.oxysporum ciceri and F.o.c.+ T. asperellum treated plots. Microplot field trials T.asperellum treated plots gave higher number of pods per plant ( 47.25 ; 44.50 ) than control, F.oxysporum ciceri treated, and F.oxysporum ciceri + T.asperellum treated plots (8.25 & 12.25 ). T. asperellum treated plants yielded maximum functional nodules. Therefore, T.asperellum is very active growth promotion including enhancing functional root nodules and fusarial wilt management in chickpea crop. This biocontrol agent (BCA) and Plant growth promotion (PGP) agent in a dose of 108spore /ml by seed dressing may be alternative to chemical fertilizers and fungicides in chickpea cultivation and other crops.
