Abstract

Sesame flowers are often visited by a myriad of insects and they play an important role in crop pollination. Determination of role of insect pollinators on qualitative and quantitative yield parameters is of great importance. Hence the present study was conducted on two selected sesame varieties, HT-1 and HT-2 at the CCS Haryana Agricultural University Research Farm in Hisar during the kharif of two consecutive years, 2017 and 2018. The results revealed a significant difference in all the recorded parameters, viz., capsule setting percent, number of capsules, 1000 seed weight, seed yield, germination percent, seed vigour and oil content in the provided treatments. Bee pollinated plots were found to be superior, followed by open pollination, while the plots without insect pollination had shown the lowest improvement in the observed parameters. Among the bee-pollinated treatments, Bee Pollination-8F (Apis mellifera F. hive with 8 frame strength) was the best treatment, followed by Bee

Conclusion

The present study provided evidence that insect pollination can improve sesame yield parameters. The impact of open pollination (OP) and a variety of bee-pollinated treatments (8F, 6F, 4F) on yield parameters were significantly greater than that of the without insect pollination treatment (WIP). In both the selected varieties, the plot with eight framed beehive was found superior followed by a plot with six framed and four framed hives. Bees were successful in transferring pollen from anthers to stigma, allowing ovules in the ovary to fertilize on time. As a result of frequent visits of A. mellifera hive bees, the ovary was properly filled, resulting in an increase in capsule setting percentage, capsule weight, seeds per capsule, and seed yield. Further, there was the enhancement in other important quality parameters viz., seed germination, seed vigour and oil content. These results imply that pollinators visiting crops at the right time of phenology could boost sesame yields.
