Abstract:
A field experiment was conducted in the rabi season at Department of Vegetable Science, N.D.U.A. & T., Faizabad (U.P.) during 2015-16, to find out the suitable doses of organic manures for sustainable production of Sweet Potato (Ipomoea batatas L.). The total of eleven doses of organic manures along with different combinations was evaluated by using randomized block design. Earliest initiation of buds (7.93 days) was observed in T₁ (FYM @ 20 t/ha). T₁₁ {recommended dose of FYM (10 t/ha) and NPK (50:25:50)} was identified as a good combination for number of leaves per plant, leaf area, foliage weight per plant, number of vine per plant, inter nodal length, number of tuber plant, fresh weight of tuber per plant, length of tubers and yield per hectare. However for all organic sources, treatment T₇ {FYM @ 10 t / ha + Poultry manure @ 2.5 t/ha + Azospirillum (5 kg/ha) + PSB (5 kg/ha)} could be used for improving growth and yield along with related traits of sweet potato. Hence, it is suggested that these remunerative treatment of organic doses help in successful crop production of sweet potato.
