| Abstract:
The propagule of true potato seed (TPS) has a promising potential for potato production in developing countries. The TPS tended to produce smaller tubers and lower yields. The trials are conducted in Wageningen, The Netherlands, from May to August 1991 on sandy soil, using TPS hybrid. The objectives of the research were to investigate the effect of planting depth and hilling up on the growth and yield in potato crops grown from true potato seed (TPS). A 2 x 3 factorial experiment in a randomized complete block design with three replications was used. One month old seedlings of TPS were planted with all leaves above ground (normal planting) and two nodes were buried (deeper planting). Hilling up treatment consisted of hilling up 1 x and 2 x (2, 4 weeks after transplanting, respectively), and they were compared with no hilling. Plating with all leaves above ground was the best technique because it tended to produce a higher yield. Hilling up was not necessary because it neither increased yield significantly nor increased marketable yield. By hilling operation, the quality of tuber was improved due to less greenish tubers. | |
