The treatments comprised of organics (FYM, Vermicompost, Biogas spent slurry, redgram stalk, in situ green manure), inorganics (N, P2O5 and KjO) and biofertilizers (VAM, P-solubilizers and Free nitrogen fixers ). Application of organics viz., FYM (794.08 kg ha"'), redgram stalk (781.60 kg ha"') and BSS (738.61 kg ha"') along with 100 per cent RDF increased the fruit yield by 26.14, 24.12 and 17.31 per cent with an additional income of Rs.5110, 4350, and 1670 ha"' respectively over 100 per cent RDF alone. The growth and yield components, N, P, K, Fe, Cu, Mn and Zn uptake both at flowering and harvest increased significantly with application of organics (FYM/rcdgram stalk/BSS) and inorganics (100% RDF > 50% RDF). The microbial population (Mycorrhizal spore count, rhizosphcre population of P solubilizer, FNF, TBC, TFC) increased by two to three folds due to application of organics. The incidence of Murda and leaf curl index (LCI), the per cent and weight of discoloured fruits reduced significantly due to application of organics. The quality parameters viz., ascorbic acid, capsaicin and per cent oleoresin content increased with application of organics and inorganics. Inoculation of VAM + P solubilizer along with 50 per cent MRP + 50% SSP (883.02 kg ha') increased fruit yield by 21.63 per cent, with a net returns of Rs.20,990 ha' as compared to 100% SSP alone (725.97 kg ha' with net returns Rs.14,960 ha'). The growth and yield components, uptake of N,P,K, Fe, Cu, Mn, Zn both at flowering and at harvest, the microbial parameters like mycorrhizal spore count, PRC, rhizosphere population, P solubilizers FNF, TBC, TFC increased significantly with dual inoculation of VAM+P solubilizer with 50% MRP + 50% SSP. The per cent and weight of discoloured fruits, incidence oi Murda and LCI were minimum. The quality parameters like, ascorbic acid, capsaicin and oleoresin yield (91.64 to 131.00 kg ha') increased with application of VAM + P solubilizer in combination with 50% MRP + 50% SSP.ennullThesis
