IMPACT OF ORGANIC MATTER AND SOIL TYPES ON THE DEVELOPMENT OF FUSARIUM WILT OF CHILLI

The research was conducted to find out the most significant concentration of organic matter and soil types for diminishing disease incidence on chilli. In contemporary studies, two experiments were conducted to evaluate the impact of organic manures (OM) and soil types on the development of Fusarium wilt in greenhouse in pots which are filled with infested soil, under completely randomized design (CRD). In first experiment, different levels (0.5, 1, 1.5 and 2%) of cattle and poultry manures were evaluated. Cow manure expressed 33.23, 25.20, 22.26 and 17.23% and poultry manure exhibited 38.23, 27.26, 23.30 and 19.30% disease incidence at 0.5, 1, 1.5 and 2% OM, respectively. In second experiment, two varieties of chilli pepper viz. Desi and Maxi were grown in different soil types i.e. sandy, clay and sandy loam soils. These varieties (Maxi and Desi) expressed 63.27 and 49.27 percent disease incidence respectively in sandy loam soil whereas similar varieties exhibited 36.27 and 29.57 percent disease incidence in clay soil. Similarly, these varieties showed 25.23 and 23.43 percent disease incidence in sandy loam soil. It was statistically concluded that minimum disease was expressed by cow manure at 2% OM and sandy loam soil among other soil types.
