An experiment was conducted to study the effect of organic sources of nutrients on orange fleshed sweet potato (Ipomoea batatas L.) under Godavari alluvial soils at Horticultural research station, Dr. Y. S. R. Horticultural University, Kovvur, West Godavari District, Andhra Pradesh during Rabi 2018-19 to study the effect of different organic sources of nutrients in sweet potato hybrid PSP-1 under organic conditions. The experimental design adopted was the mixed factorial RBD with three levels of organic manures (FYM @ 13.6 t/ha, Vermicompost @ 8.3 t/ha and Neem cake @ 9.3 t/ha) and with five levels of foliar sprays (Seaweed extract @ 3 %, Humic acid @ 4 %, Jeevamruth @ 500 l/ha, Arka microbial consortium (soil drenching) @ 7.5 l/ha and Water spray). The results revealed that the basal application of vermicompost @ 8.3 t/ha along with soil drenching of Arka microbial consortium @ 7.5 l/ha recorded highest starch content (20.24 %), total sugars (3.28 %), reducing sugars (0.50 %), ascorbic acid content (3.49 mg/100g) and β-carotene (14.22 mg/100g).
