ThesisItem Open Access INTEGRATED NUTRIENT MANAGEMENT FOR CHILLI (Capsicum annuum L.) IN ALFISOLS OF NORTHERN TRANSITION ZONE OF KARNATAKA(UNIVERSITY OF AGRICULTURAL SCIENCES GKVK BANGALORE, 2001-08-02) SHASHIDHARA, G. B.; NADAGOUDA, Dr. V. B.Field experiments were conducted at Agricultural Research Station, Hanumanamatti, University of Agricultural Sciences, Dharwad during 1996 and 1997 in a fixed site to study the effect of integrated nutrient management on growth, yield and quality of chilli under rainfed condition. 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.ThesisItem Open Access INTERCROPPING OF GROUNDNUT WITH MINOR MILLETS ON ALFISOLS OF NORTHERN TRANSITION ZONE OF KARNATAKA(University of Agricultural Sciences, Dharwad, 2015-07) HONNATTI, SHIVARAJ D.; SHASHIDHARA, G. B.The field experiment was conducted at Saidapur farm, Main Agriculture Research Station, Dharwad on Alfisols during kharif season of 2014 to study the effect of intercropping of groundnut with minor millets viz., foxtail millet, finger millet and little millet under different row proportions. Millets were intercropped with groundnut at different row proportions (2:1 and 4:2) along with three sole treatments of millets and groundnut. Growth parameter of groundnut viz., leaf area, leaf area index, total dry matter production and yield attributing characters viz., number of pods per plant, pods weight per plant and test weight were significantly higher in 4:2 row ratios of groundnut + millets intercropping systems compared to respective sole cropping. Sole groundnut recorded significantly higher pod yield (3047 kg ha-1) and haulm yield (4147 kg ha-1) over intercropping systems. Yield components such as number of tillers, grain weight per panicle, number of panicles and test weight were significantly higher in groundnut + millet intercropping treatments in 4:2 row ratios. Sole finger millet recorded significantly higher yield attributing characters, grain yield (2628 kg ha-1) and haulm yield (3028 kg ha-1) than other cropping systems. The highest Groundnut Pod Equivalent Yield (GPEY), Land Equivalent Ratio (LER) and Area Time Equivalent Ratio (ATER) were recorded with groundnut + finger millet (2916 kg ha-1, 1.22 and 1.17 respectively) followed by foxtail millet (2792 kg ha-1, 1.21 and 1.13 respectively) in 4:2 row ratio. Net and gross returns were significantly higher in sole groundnut (` 1,26,857 ha-1 and ` 83,778 ha-1). However it is on par with 4:2 row ratios of groundnut + finger millet (` 1,21,584 ha-1 and ` 80,497 ha-1 gross and net returns respectively). Maximum benefit: Cost ratio was realized with groundnut + finger millet in 4:2 row ratio (2.96), whereas it was on par with sole groundnut (2.94).
