EFFECT OF NITROGEN AND FYM INTERACTION ON YIELD AND YIELD TRAITS OF POTATO GENOTYPES UNDER LADAKH CONDITION

Abstract

The experiment was carried out at Regional Agricultural Sub-Station, SKUAST-K, Kargil during 2004 and 2005. The treatments consisted of 4 genotypes of potato (Kufri Chandramukhi, K. Jyoti, PP-48 and PP-2500), 3 levels of N (60, 120 and 180 kg/ha) and 2 levels of FYM (15 and 30 t/ha). Genotype PP-2500 recorded highest yield followed by Kufri Chandramukhi, K. Jyoti and PP-48. The interaction effect of genotypes, levels of N and FYM was significant in both the years with maximum tuber yield recorded with 180 kg N + 30 t FYM/ha, which was statistically at par with 120 kg/ha N + 30 t FYM/ha. It was concluded that potato genotype PP-2500 and Kufri Chandramukhi supplemented with 120 kg N + 30 t FYM/ha was the best for commercial cultivation under cold arid conditions of Ladakh.
