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. T
1 FYM @ 20 t/ha,T
2Poultry manure @ 5t/ha,T
3 Neem cake @ 4t/ha + Azospirillum5kg/ha + PSB5kg/ha, T
4 Vermicompost @ 5t/ha + Azospirillum5 kg/ha + PSB5kg/ha, T
5FYM @ 10t/ha + Vermicompost 2.5t/ha + Azospirillum5 kg/ha + PSB5kg/ha, T
6FYM @ 10 t / ha + Neem cake @ 1t/ha + Azospirillum(5 kg/ha)+PSB5kg/ha, T
7FYM @ 10t / ha + Poultry manure @ 2.5t/ha + Azospirillum5 kg/ha + PSB5kg/ha,T
8 Vermicompost @ 2.5t/ha + Neem cake @ 1t/ha + Azospirillum5 kg/ha + PSB5kg/ha,T
9 Vermicompost @ 2.5t/ha + Poultry manure 2.5t/ha + Azospirillum5 kg/ha + PSB5kg/ha,T
10 1/2 Recommended dose of Fertilizers + Azospirillum2.5 kg/ha + PSB2.5kg/ha,T
11 Recommended dose of FYM and NPK 10t/ha & 50:25:50, The experimental results revealed that the use of T
11 Recommended dose of FYM and NPK 10t/ha & 50:25:50 was found better with respect to all the growth parameters like number of vine per plant, inter nodel length (cm). The yield contributing characters such as number of tuber plant
-1, weight of tuber plant
-1 and yield ha
-1 (q) of sweet potato crop were significantly higher by use of T
11 Recommended dose of FYM and NPK 10t/ha & 50:25:50.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.
