Abstract:

An experiment was conducted entitled Effect of nitrogen and potassium on growth, yield and quality of orange fleshed sweet potato (Ipomoea batatas Lam.) was carried out during the rabi season, 2018-2019 at Horticultural Research Station, Peddapuram, East Godavari District of Andhra Pradesh. The study was carried out with 4 levels of nitrogen and potassium and was laid out in a factorial randomized block design (FRBD). The different levels of nitrogen had significant influence on the plant growth parameters, yield parameters and quality parameters. The soil application with 120 kg N ha-1 has recorded highest values for all the studied parameters except starch and reducing sugars. While the highest starch and reducing sugars were found with application of 30 kg N ha-1 and 90 kg N ha-1 respectively. The influence of different levels of potassium on all the studied parameters was significant except reducing sugars and recorded the maximum values with the application of 120 kg K ha-1. The nitrogen and potassium interaction effects were non-significant for most of the parameters except for vine length at final harvest, number of branches per vine, number of leaves per vine at 90 DAP & at final harvest, total leaf area per vine at all growth stages, root tuber girth, root tuber yield per vine, root tuber yield per plot, estimated root tuber yield per hectare, beta carotene, starch which were differed significantly. The maximum values for all significantly differed parameters were found with application of 120 kg N ha-1 and 120 kg K ha-1. Among the different treatment combinations, it was found that the treatment combination of nitrogen at 120 kg ha-1 and potassium at 120 kg ha-1 (T16) proved to be the best for cultivation of orange fleshed sweet potato.
