Effect of growing season on the oil content percentage of five sesamum genotypes in six developmental stages

Abstract

In the current investigation, the oil content percentage of five sesamum genotypes (Uma, Amrit, Nirmal, CUMS-17, Prachi) in six developmental stages (7 DAA, 14 DAA, 21 DAA, 28 DAA, 35 DAA and 42 DAA ) were estimated in three growing seasons (summer, kharif and rabi). The field and lab experiments were carried out in Seed Science and Technology Department, OUAT, Bhubaneswar. The oil content percentage increased consistently up to 42 DAA but there was no significance difference between 35 DAA (maturity stage) and 42 DAA. Prachi and CUMS-17 (46.6%, 44.9%) recorded the highest oil content percentage in seeds throughout the period of seed development, respective at maturity stage and Uma was the lowest (41.6%). By comparing the three growing seasons, the kharif harvest seeds recorded the highest oil content (44.9%) followed by summer (43.5%) and rabi (42.6%) at maturity stage.
