EFFECT OF SPLIT DOSES OF N AND K AND FYM LEVELS ON THE PRODUCTIVITY OF SEED POTATO IN COLD DESERT REGIONS OF H.P.

major cash crops of Himachal Pradesh. The high altitude disease free potatoes are preferred for seed in various parts of the country. Due to poor soil status, fluctuations in day and night temperatures and desiccating winds, yield of potato is very low in Spiti Valley. The integrated use of fertilizer nutrients i.e. N and K, and FYM play vital role in boosting production (7, 8, 9). But due to high mobility of N and K resulting in their loss on account of frequent irrigation. The present investigation was undertaken to study the response of split application of N and K and doses of FYM in seed potato production in cold desert region.
