Effect of NPK fertilizers on yield of oil and npk contents of sesame seeds (Sesamum indicmt)

Abstract

A pot experiment was designed in a 3® factorial combination with partial confounding to measure th« effect of N ( 0, 90, 180 kg/ha ), P and K ( each at 0, 22, 44 kg/ha ) on yield of oil and NPK contents of sesame seeds ( Sesamum indicum), individual application of N, P and K fertilizera produced significant impact on oil content of sesame seeds. Amongst them P showed its effectiveness most. N and P combinations were welleffective in increasing oil content. NPX at the highest levels was most promising in yielding oil. NPK at the medium rates also exhibited a nearly similar effect on oil content. N, P and K content of seeds were significantly varied by N application alone. In all respects, N ( 90 kg/ha ) plus PK ( each 22 kg/ha) played better in increasing the amounts of N, P and K in seeds.
