Abstract
The effect of harvest time on yield of ubi Nagara (Ipomoea batatas) at medium deep swampland, South Kalimantan. Quality of Ubi Nagara tuber affected by harvest time and intensities of tuber damaged caused by pest (hama boleng) or (Cy/as sp) attacked. The study conducted at Habirau, Daha Sub District, South Kalimantan in wet season 1994. Variety of Kiyai Baru was planted at 1 x 1 m space. The trial used Randomized complete block design, with five replications. Five harvest time were tested i.e. 1) 90 days after planting, 2) 100 days after planting, 3) 110 days after planting, 4) 120 days after planting, and 5) 130 days after planting. Basal fertlizers were 90 kg N/ha, 60 kg P205/ha, and 60 kg K2/ha, represented by Urea, TSP and KCI respectively. The parameters observed were: weight of wet tuber, amount, length, diameter, and yield of tubers. Ubi Nagara can be harvested at 120 days after planting, and the highest yield of 46,13 tlha obtained at 130 days after planting. Less intensity of pest (Cy/as sp) attacked to Ubi Nagara tuber.
