Abstract
Mung bean (Vigna radiate L.) belongs to the Leguminosae family and one of the most popular short duration pulse crops of India. It is one of the essential food legumes cultivated worldwide. is an excellent source of high-quality protein and contains about 22-25% protein, 1.0-1.5% oil, 3.5-4.5% fibre, 4.8% ash and 62-65% carbohydrates on dry weight basis. It is easily digestible and hence it is suitable for all age group of people and green fodder to feed animals. Rhizobia are Gram-negative bacteria that can form root nodules in leguminous plants and provides the nitrogen through fixation process which can limit the use of chemical fertilizer. Trichoderma belongs to the Deuteromycetes class of fungi and has been exploited as biocontrol agents against a diversity of plant pathogenic fungi.
In the present investigation, mung bean cultures and Trichoderma isolates were screened for their compatibility. Trichoderma asperellum and Rhizobium MB 17a were found compatiblemwere then optimized for their growth interaction. The coculture was found to be more effective when tested for their antagonistic activity against Macrophomina phaseolina. The coculture recorded higher plant growth promoting traits including IAA production, ammonia excretion phosphate solubilization, , zinc solubilization, siderophore production, HCN production and ACC utilization. were evaluated for growth promotion of mung bean under pot culture conditions during 2020. Rhizobium and Trichoderma coculture gave best results in improving growth and seed yield of mung crop.
