INFLUENCE OF ARBUSCULAR MYCORRHIZAL FUNGI ON PLANT GROWTH PROMOTION AND BIOLOGICAL CONTROL OF VERTICILLIUM WILT OF TOMATO (LYCOPERSICON ESCULENTUM).
Tomato ( lessThan i greaterThan Lycopersicon esculentum lessThan /i greaterThan Mill) is an important vegetable crop and is known as productive as well as a protective food because of its therapeutic values. Arbuscular mycorrhizal fungi are known to enhance plant growth mainly through nutrient uptake. Indigenous arbuscular mycorrhizal fungi lessThan i greaterThan Glomus fasciculatum lessThan /i greaterThan (Thaxt.) Gerd. & Trappe, was inoculated in field conditions using three different cultivars of tomato viz., PKM-1, Gaurav and Monarch. Various morphological parameters, nutrient levels and disease incidence were evaluated. A significant increase in shoot and root leaf lengths, shoot and root fresh, dry weights, biomass, dry matter production and nutrient levels NPK were recorded in AM fungi treated plants over controls. There was a maximum reduction of disease incidence by 53.18% in Monarch cultivar in the plants inoculated with AM fungi in combination with the pathogen lessThan i greaterThan Verticillium dahliae lessThan /i greaterThan compared to only pathogen inoculated plants. This was followed by 49.55% and 45.48% in Gaurav and PKM-1 cultivars respectively. All the three cultivars have shown positive response to lessThan i greaterThan Glomus fasciculatum lessThan /i greaterThan recording significant increase in plant growth and reduction in percentage of disease incidence.
