Abstract

A study was conducted during the winter (October to February) of 2008/09 in the farmers’ field to standardize the appropriate dose of nitrogen and potash for the higher productivity and profitability of TPS technology at Mangalpur, Chitwan. The planting material used for ware potato production was seed tuber of a first generation clonal progeny of hybrid TPS namely, HPS II/67. The treatment consisted of four levels of nitrogen (50, 100, 150 and 200 kg/ha) and four levels of potash (40, 70, 100 and 130 kg/ha). The treatment consisted of four levels of nitrogen (i.e. 50, 100, 150 and 200 kg N/ha) and four levels of potash (40, 70, 100 and 130 kg KO/ha). Nitrogen 50 kg/ha produced the lowest yield per plant. Similarly, potash 130 kg/ha produced significantly higher yield per plant which was at par with 100 kg KO/ha. The treatment combination of 150 kg N/ha and 100 kg KO/ha gave the highest tuber yield (30.42 and 29.18 mt/ha) respectively, and large sized tuber. The highest physiological weight loss was observed at nitrogen level 50 kg N/ha and potash 130 kg/ha. The dry matter percentage was recorded to be the highest with nitrogen level at 150 kg N/ha. On the contrary, the lowest level of potash produced the maximum dry matter. Therefore, the study showed that potato production through clonal progeny of HPS II/67 should be done with fertilization of 150 kg N/ha and 100 kg KO/ha to optimize yield at Mangalpur, Chitwan condition.

Keywords: ware potato, standardize, clonal progeny, parameter.
