Title of Thesis : “Effect of different sources of organic manure and their combination on yield and nutrient uptake by chilli (Capsicum annum L.) in lateritic soil of Konkan” ====================================================== ABSTRACT The present investigation entitled “Effect of different sources of organic manure and their combination on yield and nutrient uptake by chilli (Capsicum annum L.) in lateritic soil of Konkan” was conducted at Vegetable Improvement Scheme, Pangari Block, Wakawali during Rabi season 2014-2015. The field experiment was laid out in Randomized Block Design comprising of thirteen treatments replicated thrice. Treatments comprised of T1 [25% N through FYM + 75% N through Urea], T2 [50% N through FYM + 50% N through Urea], T3 [75% N through FYM + 25% N through Urea], T4 [25% N through Vermicompost + 75% N Urea], T5 [50% N through Vermicompost + 50% N through Urea], T6 [75% N through Vermicompost + 25% N through Urea], T7 [25% through N Poultry manure + 75% N through Urea], T8 [50% through N Poultry manure + 50% N through Urea], T9 [75% N through Poultry manure + 47 75% N through Urea], T10 [25% N through Groundnut cake + 75% N through Urea], T11 [50% N through Groundnut cake + 50% N through Urea], T12 [75% N through Groundnut cake + 25% N through Urea] and T13 [Absolute control]. The initial experimental soil was sandy clay loam in texture, slightly acidic in reaction and low in electrical conductivity. The soil was to be found very high in organic carbon and was low in available N and P2O5. The soil was high in available K2O. DTPA extractable micronutrients (Fe, Mn, Zn and Cu) were found to be 28.86, 114.0, 0.372 and 2.752 (mg kg-1), respectively. It was observed that the substitution of N through poultry manure to the extent of 50 per cent (and remaining 50 per cent through urea) was observed to be the best treatment amongst different combinations of organic manures with urea. It produced highest yield (Green, dry matter of green chilli pod and stover) of chilli and weight of fruit per plant while application of 75 per cent N through Poultry manure and 25 per cent N through urea recorded highest plant height at different stages (i.e. 30, 60 DAT and at harvest). The quality parameter as indicated by ascorbic acid and capsaicin content, the NPK uptake by green pod and stover was also recorded maximum in combined application of organic and inorganic fertilizers. It was also observed that the residual available nutrients in soil also significantly influenced due to integrated nutrient management. It could be concluded from the above investigation that the different combination of poultry manure with urea (50 per cent through poultry manure and 50 per cent N through urea, 75% N through poultry manure and 25% N through urea) was found to be the best treatments in increasing yield (stover and pod) of chilli Var. Konkan Kirti as well as improving the soil properties in lateritic soils of Konkan.ennullThesis
