A field experiment with eight treatment combinations of bio-pesticide and application methods was conducted to study the efficacy in improving the planting value and maintenance of seed quality of sweet pepper in storage. The studies revealed significant effect of bio-pesticides on seed yield and quality. The bio-pesticides apart from increasing the defence responses of the plants had also increased the seed germination percentage, seedling emergence and growth characteristics. Furrow application with mustard oil cake was most effective for enhancing plant height, fruit number per plant, fruit length and girth, seed number per fruit and yield. Seed treatment and furrow application with jatropha oil was equally effective as furrow application with mustard oil cake. Minimum days to 50 % flowering and fruit setting were observed in seed treatment with jatropha oil and seed treatment and furrow application with jatropha oil respectively and lowest infestation of insects was registered per plant in combined application of insecticide and miticide. Considering the maintenance of seed quality, seed treatment with jatropha oil, seed treatment and furrow application with jatropha oil along with furrow application with jatropha oil and furrow application with mustard oil cake were most promising treatments even after 180 days of storage. These treatments recorded higher germination, root and shoot length, seed vigour index, seed viability and less seed infection than the synthetic pesticidal treatments.
