Abstract

Sweet potato (Ipomoea batatas L.) root tubers and vines are important for human and animal nutritional requirements, respectively; the vines being additionally used for propagation, but root tuber yield is greatly affected by vine harvesting frequency. This study aimed at assessing the potential effect of vine harvesting frequency of sweet potato German 11 cultivar on attributes of root tuber yield under sprinkler irrigation after 140 days from planting. Treatments used consisted of vine harvesting once (VHO) at 8 weeks after planting, 2 times (VH2T) at 8 and 10 weeks after planting; 3 times (VH3T) at 8, 10 and 12 weeks after planting; and 4 times (VH4T) at 8 weeks, 10 weeks, 12 weeks and at 14 weeks after planting. No vine harvesting was the control. Treatments were arranged in a randomized complete block design (RCBD) and replicated three times. Results revealed that vine harvesting frequency had a relative effect on all root tuber yield attributes of sweet potato. The lower the vine harvesting frequency the higher the yield obtained. Vines harvested once (VHO) at 8 weeks significantly (P<0.001) increased root tuber dry matter (DM) (29.3%) and total root tuber yield (14.5 t ha-1) as compared to VH4T, and also gave optimum results in all the root tuber yield parameters measured. Based on the results, optimum German 11 cultivar production capacity is achieved when vine harvesting for livestock feeding and propagation is done only once at 8 weeks.
