Response of Sweetpotato [Ipomoea batatas (L.) Lam.] to Five Rates Each of Nitrogen and Phosphorus under Guinea and Sudan Savannah Agroecological Zones of Ghana
A multi-locational field experiment was conducted to evaluate the effects of increasing rates of nitrogen and phosphorus on sweetpotato growth and yield at Bawku and Nyankpala. Shoot yield increased by 31%, 63%, 94% and 125% in Bawku and 49%, 98%, 148% and 197% in Nyankpala, when nitrogen was applied at 30, 60, 90 and 120 kg？ha？1, respectively. When nitrogen was applied at 30, 60, 90 and 120 kg？ha？1, storage root yield increased by 30, 46, 48, and 37% in Bawku and by 13, 17, 14 and 3% in Nyankpala, respectively. The optimum nitrogen required to maximize storage root yield were 80 and 62.5 kg？ha？1 for Bawku and Nyankpala, respectively, in a split application at 2 and 6 weeks after planting. Storage root yield increased by 4%, 5%, 2% and ？4% in Nyankpala and by 54%, 81%, 82%, 56% in Bawku, when 40, 80, 120 and 160 kg P were applied. Optimum phosphorus required to produce the highest storage root yield in this study are 67.5 and 101.3 t？ha？1 for Nyankpala and Bawku, respectively. The maximum net return to investment occurred when 60 kg N？ha？1 and 40 kg P？ha？1 were applied at Bawku and Nyankpala, respectively.
