Impact of NPK fertilizers on the growth, yield and oil content of sesame (Sesamum Indicum )

Abstract

A pot experitneiu was conducted in a 3^ factorial design with partial confounding to evaluate the effect of HPK on S e s a m u m indicum ( var. Ganga ). NPK did not signiHcintly affect the height of the plant in the eatly statje of growth Increased height was attained at maturity by N, P and NP fertilization. In csntraat, K, NK and NP produced some growth retarding effect. N and NP combinations appeared to be effective in pod setting but P, K and PK combinations proved to be of no use in this respect. Yield of seeds was in general at par with pod setting. The highest yield was recorded at 224 kg/ha with each of N, P and K. Yield of seeds in general followed the same pattern as pod setting. N, NP, NK and NPK treatments appeared to Increase oil content in seeds by more than 5 tinr.es.
