SUMMARY

Four maize hybrids were subjected to various viability and vigour tests to evaluate the effect of planting season on seed yield and yield attributing characteristics during 2016-17. The results
revealed that the crop grown during rabi season showed its superiority in yield and yield components over kharif season by registering maximum field emergence index (31.97), seedling establishment (78.82%), days to 50% tasseling (122), days to 50 % silking (127), number of leaves per plant (12.98), number of cobs per plant (1.42), plant height at maturity (1.80m), cob length (33.08cm), number of seeds per cob (424.08) and seed yield (99.36g/cob). Among the hybrids, maximum yield and yield attributing characters was recorded in HPQM 5 in both the seasons with maximum field emergence index (29.85), seedling establishment (75.07%), days to 50% tasseling (91.00), days to 50 % silking (94.50), number of leaves per plant (13.47), number of cobs per plant (1.52), plant height at maturity
(1.81m), cob length (31.75cm), number of seeds per cob (444.38) and seed yield (112.61g/cob) whereas minimum was observed in HM 9 in both the season with field emergence index (24.10), seedling establishment (64.03%), days to 50% tasseling (87.17), days to 50 % silking (90.67), number of leaves per plant (12.08), number of cobs per plant (1.04), plant height at maturity (1.56m), cob length (25.64cm), number of seeds per cob (395.50) and seed yield (76.43g/cob). Therefore it can be concluded from the study that more yield can be achieved during rabi season as compared to kharif season, thus rabi season can be considered as a better option for production of quality seed in Hisar region.
