Implication of Solarization against Soil borne fusaria in leguminous crop fields in Kalli paschim village in Lucknow, India: A Tropical Country

Soil solarisation is a technique to trap sun's energy helps to increase the temperature of the soil.This higher temperature is unsuitable for most of the plant pathogens results decreased in their population. It's a very beneficial technique for management of pathogen microbes in tropical countries where sunlight is available for a long period in a day time. Soil solarisation also helps to increases the productivity of soil both by suppressing the pathogens as well as by increasing the metabolic rate of soil materials, which helps to enhance the fertility of the soil. This procedure is also enhancing the bulk and bustle of antagonistic microbes. The purpose of present study is to test the effect of soil solarization on population dynamics of two pathogenic soil fusaria i.e. Fusarium oxysporum f.sp.ciceri and fusarium udum causing wilt in chickpea and pigeonpea crops. All treatment comprises treated plots and untreated (control) plots at different depth i.e. 5, 10 and 15 cm on 7, 14 and 21 ^st days of experiment. It is found that in solarized plots the population of pathogens significantly reduced in compared to control plot. Significant increase in temperature is found in solarized plots in comparison to control with increase in days of experiment.
