dc.description.abstractAbstract: Field investigation entitled “Effect of organic sources of nutrients on cotton based intercropping system” was carried out during kharif season 2019-20 at research farm of Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (Maharashtra). The experiment was laid out in Strip Plot Design (SrPD) with four mainplot factors i.e. intercropping system (T1 – Cotton + Blackgram 2:1, T2 - Cotton + Sunhemp 2:1, T3 - Cotton + Pigeonpea 6:1 and T4 – sole Cotton and three sub plot factors i.e. organic integrated nutrient management (N1 – 100% FYM + Vermicompost, N2 – 75% FYM + Vermicompost + 25% Neem cake and N3 – Control) replicated three times. The varieties adopted are AKA-7 (Cotton), Blackgold (Blackgram). PKV-Tara (Pigeonpea) and Local (Sunhemp). Plant height (cm) was higher in cotton + sunhemp (2:1) intercropping system. Leaf area, number of sympodial branches, dry matter accumulation, root length and root dry weight was highest at 120 DAS in cotton + sunhemp (2:1). Higher chlorophyll content was recorded in cotton + sunhemp (2:1) intercropping system. Total leaf biomass added (kg ha-1) and total biomass added for in-situ decomposition (kg ha-1) was higher in Cotton + Pigeonpea (6:1) intercropping system than other intercropping system. Number of picked boll plant-1 and seed cotton yield plant-1 was higher in cotton + sunhemp (2:1) intercropping system due to the better growth of cotton crop. Seed cotton yield (kg ha-1), stalk yield (kg ha-1) and lint yield (kg ha-1) was higher in sole cotton rather than other intercropping system. Higher seed cotton equivalent yield (kg ha-1), system productivity and total uptake of N and K (kg ha-1), GMR, NMR, B:C ratio and system profitability was recorded in cotton + pigeonpea (6:1) intercropping system. Among the organic integrated nutrient management treatments, application of 75% FYM + Vermicompost + 25% Neem cake influenced plant height (cm) at 60DAS, leaf area (dm2) at 60 DAS, sympodial branches at 60 DAS, dry matter accumulation plant-1 (g) at 60 DAS, SPAD reading at 60 DAS, seed cotton yield (kg ha-1), stalk yield (kg ha-1) and NPK uptake. Soil fertilitystatus was higher in 75% FYM + Vermicompost + 25% Neem cake treatment. Treatment with 75% FYM + Vermicompost + 25% Neem cake recorded higher seed cotton equivalent yield (kg ha-1), Gross monetary and comparable net monetary returns (Rs. ha-1).en_US
