Abstract

An experiment was conducted during 2010-11 to study the Impact of nutrients and organics on quality, biochemical status and yellow vein mosaic virus disease incidence of okra. The results pooled over two seasons indicated that the yield and quality parameters viz., yield/plot, total carbohydrates and protein were the highest, while crude fibre was the lowest were observed with application of Pseudomonas fluorescens. The enhanced activities of total phenol, peroxidase and polyphenol oxidase (PPO) in healthy and infected leaves due to application of P.fluorescens (seed treatment @ 10g kg-1 + soil application @ 2.5 kg ha-1 with FYM + foliar spray @ 0.2%) in split doses were found to be responsible for the reduction in whitefly population and yellow vein mosaic virus disease incidence.
