Studies on influence of sowing dates on quality hybrid seed production of sorghum, CSH 16 revealed that the parental lines of CSH 16 sown on 1.10.2014 were near to synchronization of flowering and took more days for completion of flowering as compared to the other two dates (17.10.2014 and 31.10.2014) of sowing. Higher grain yield plant 1 was recorded when the parental lines were sown on 01.10.2015 as compared to the later sowings. Delay in sowings by 15 days and one month i.e., from first of October to mid of October and end of October, reduced the yield of the crop by 13.89% and 53.28%, respectively. Germination percentage of the hybrid seed harvested from crop sown on 1.10.2014 was highest (90%) to the hybrid seed harvested from the crop sown on 17.10.2014 and 31.10.2015. Therefore it is evident that early sowing (first week of October) of parental lines of sorghum hybrid CSH 16 results in higher hybrid seed yield with seed quality.
