Multiplication of Arbuscular Mycorrhiza on Chickpea and their Co-inoculative Impact with Trichoderma sp. on Chilli Wilt

Abstract

Fusarium wilt has emerged as a serious problem in all chilli growing areas of India. Due to difficulties in disease management and lack of stable genetic resistance in chilli cultivars, integration of arbuscular mycorrhiza and Trichoderma were used to manage the disease. Different mycorrhizal fungi were raised and maintained on chickpea in earthen pots. A further experiment was conducted and Plant height, Root length, Dry weight of root and shoot, Mycorrhizal colonization (Phillips and Hayman method), Sporocarp number (Gerdemann and Nicolson method), SPAD chlorophyll content (SPAD meter) and NPK content were investigated. The present investigation deals with the beneficial effect of Glomus intraradices and Trichoderma harzianum on chilli wilt under greenhouse. In soil (Chickpea) sporocarp population of Glomus intraradices (5283) in 100 g soil and mycorrhizal colonization of Glomus intraradices (87 per cent) was observed. Chilli plant showed a significant increase in the Plant height, Root length, Dry weight of root and shoot, SPAD chlorophyll content and NPK content as compared to control. The results revealed that mixed Fusarium oxysporum + Glomus intraradices + Trichoderma harzianum inoculation contribute best growth and development of chilli plant under greenhouse experiment at 90 days after transplanting.
