Abstract:

Nearly 75% of the world’s flowering plants are dependent on insects for pollination, with honeybees being well known for their importance for several crops. The Experiment was conducted to know the effect of pollination involving Apis cerana as major component in the study concentrated on onion crop growth. The open pollinated plot sprayed with cacambe (10) was found significantly superior by recording highest number of seeds/umbel (930.44 seeds/umbel) which resulted in 65.92 and 126.40 per cent increase over open pollination without spray and caged plot without bees, respectively. The same treatment found to get the superior test weight (4.19 g/1000 seeds), higher net plot (4 m x 4 m) yield of 1.42 kg/plot. In case of qualitative parameters also the cacambe (10%) showed the significant result over the other treatments viz., maximum root length of 4.39 cm and maximum shoot length of 9.92 cm with an increase of 26.09 and 39.60 per cent over pollinated without spray and caged plot without bees, respectively. The next best treatments was jaggery (10%) (9.86 cm) and Bee-Q (1.25%) (9.79 cm).
