Effect of organic amendments against soybean (Glycine max l.) charcoal rot caused by Macrophomina phaseolina (Tassi.) goid

Abstract

The pot culture studies were undertaken to evaluate the efficacy of organic amendments for management of charcoal rot (Macrophomina phaseolina) of soybean (Glycine max L.). Among the 11 organic amendment tested, neem seed cake (@ 50 g/kg potting mixture) was found effective with significantly highest seed germination 79.99 %, reduction over pre-emergence seed rot 72.11 % and reduction over post-emergence seedling mortality 78.78 per cent. There was significantly least pre-emergence seed rot 20.00 % and post emergence seedling mortality 15.55 % recorded.
