Abstract
A field experiment was conducted at Main Experiment Station, Department of Vegetable Science, Narendra Deva, University of Agriculture & Technology, Narendra Nagar (Kumarganj), Faizabad (U.P.) during the Rabi season of 2015-16 to access the Response of different organic sources on growth and yield of sweet potato (Ipomoea batatas L.) cv. NDSP-65.The experiment was conducted with randomized block design replicated three times with eleven treatments viz., T1 FYM @ 20 t/ha,T2Poultry manure @ 5t/ha,T3 Neem cake @ 4t/ha + Azospirillum5kg/ha + PSB5kg/ha, T4 Vermicompost @ 5t/ha + Azospirillum5 kg/ha + PSB5kg/ha, T5FYM @ 10t/ha + Vermicompost 2.5t/ha + Azospirillum5 kg/ha + PSB5kg/ha, T6FYM @ 10 t / ha + Neem cake @ 1t/ha + Azospirillum(5 kg/ha)+PSB5kg/ha, T7FYM @ 10t / ha + Poultry manure @ 2.5t/ha + Azospirillum5 kg/ha + PSB5kg/ha,T8 Vermicompost @ 2.5t/ha + Neem cake @ 1t/ha + Azospirillum5 kg/ha + PSB5kg/ha,T9 Vermicompost @ 2.5t/ha + Poultry manure 2.5t/ha + Azospirillum5 kg/ha + PSB5kg/ha,T10 1/2 Recommended dose of Fertilizers + Azospirillum2.5 kg/ha + PSB2.5kg/ha,T11 Recommended dose of FYM and NPK 10t/ha & 50:25:50, The experimental results revealed that the use of T11 Recommended dose of FYM and NPK 10t/ha & 50:25:50 was found better with respect to all the growth parameters like no. leaves plant-1, leaf area cm2, foliage weight plant-1 (g), length of vine (cm), no. of branches vine-1, inter nodel length (cm). The maximum net return Rs. (Rs 222343.5) and benefit: cost ratio 3.6 were recorded under Recommended dose of FYM and NPK (10t/ha & 50:25:50 This was found suitable remunerative treatment and help in taking decision for successful crop production of sweet potato from farmer’s point of view.
