Studies on Bio-chemical Changes in Dry Root Rot (Macrophomina phaseolina) Infected Plants of Mungbean (Vigna radiata L.)

Mungbean (Vigna radiata L.) is one of the most ancient and extensively grown leguminous crops of India. It has proved to be an ideal crop for spring and summer/ kharif season. Mungbean belongs to family leguminosae and sub family papilionaceae. It is a short duration crop and rich in protein and vitamin B. It contains 24.5 per cent protein and 59.9 per cent carbohydrate. It also contains 75 mg calcium, 8.5 mg iron and 49 mg R-carotrne per 100 g of split dual (Bhowaland and Bhowmik, 2014). It has the capacity to fix atmospheric nitrogen through symbiotic nitrogen fixation. It is also used as green manure crop. Mungbean is prove to fungal disease, among them dry root rot incited by Macrophomina phaseolina is a soil borne pathogen. Macrophomina phaseolina survives in/on seed and persisted in the soil in the form of black sclerotia which are produced in large number on infected host tissues and are subsequently dispersed in soil during tillage operations (Sheikh and Ghaffar, 1978).
