Effect of Macrophomina phaseolina on rhizosperic soil factors of resistant and susceptible variety of Mungbean

Abstract

Macrophomina phaseolina (Tassi) Goid. incitant of dry root rot disease in mungbean is the most devastating disease in all the mungbean growing districts of Rajasthan. Different soil factors viz. soil temperature, soil moisture, pH, electrical conductivity and organic carbon were also observed at initial infested soil and rhizosphere soil of resistant MSJ-118 and susceptible RMG-62 varieties of mungbean. Soil temperature, pH and electrical conductivity decreased from initial infested soil, seedling and flowering stages of both varieties. Organic carbon increased from initial infested soil and rhizosphere soil of resistant MSJ-118 and susceptible RMG-62 varieties whereas moisture content was remains almost same at initial infested soil, seedling and flowering stages of both varieties.
