“…The treatment Bp-4F was recorded (95.1%) and BP-2 F (94.5%). The same trend, Kumar et al (2021) recorded the minimum seed germination in without insect pollination (79.33%) but (91.17%) in open pollination.…”

“…Similarly, Bondok et al (2016) showed the BP-4 F and BP-2 F treatments were significantly heavier than without insect pollination 3.56 and 3.30 g, respectively. The same trend Kumar et al (2021) found OP recorded higher 3.01g/ 1000 seed weight, while without insect pollination lighter 2.57 g. Also, Singh et al (2012) indicated lower 1000-seed weight (2.47 g) in plots caged with A. mellifera colony compared to open pollinated plot (2.51 g) and was the lowest under without insect pollination 2.22 g).…”

“…The same trend, many workers have studied modes of pollination (Hassanien ,1953, Narayanan et al1961, Chowdhury et al 1966Malavia et al1999). Similarly, Kumar et al 2021 found the minimum seed set was recorded in the without insect pollination (6.45%), while hand pollination was found over without insect pollination (8.65%). The plots for open pollination showed 74.86 percent of seed setting.…”

“…2016) and better quality of fodder (20% crude protein), high digestability (up to 65%) and high palatability (Singh et al 2019) and (FAO, 2011). Berseem is characterize by succulent, high palatability, green manures, soil fertility (Graves et al 1996, EL Nahrawy, 2005, Bakheit, 2013and Kumar, et al 2021, and nitrogen-fixing (Stewart et al 2008 andSingh et al 2019). Egyptian clover has been established as one of the best winter fodder crop in Egypt, it is the king fodder in Egypt (Badawy et al 2018).…”

“…Egyptian clover is grown for forage and seed yields, its also the essential honey producing crop (Bakheit 1989). Synergistically, honey bees are necessary for berseem clover pollination and to increase seed yield (Roy et al, 2005;Goodwein et al, 2011;Abrol, 2012, Jat et al2014and Kumar, et al 2021. About 75% of the world's flowering plants are need to insects for pollination (Bezabih and Gebretsadikan, 2014).…”

The effect of honey bees as a pollinator on quality and quantity of Egyptian clover (Trifolium alexandrinum L.) seeds was studied to get acquainted of the colony numbers (No. of frames) on seed production during 2019/2020 and 2020/2021 winter seasons. The honey bees, Apis mellifera, had significant effect in all seed treatments and four frames gave the highest seed setting. Over the two seasons, the maximum seed setting was recorded with four honey bee frames (81.6%) followed by three frames (75.5%), open pollination gave 72.1%, two frames gave 64.7%, one frame gave 59.6%, and without honey bee pollination in greenhouse gave 11.5%. Maximum seed yield was obtained by treatment of four frames (1.03kg/plot) followed by thee frames (0.944 kg/plot), two frames (0.822 kg/plot) and one frame (0.7 kg/plot). While the open pollination gave 0.89 kg/plot and without honey bee pollination gave 0.155 kg/plot. Maximum 1000-seed weight was increased by number of honey bee frames since the weight by four frames was 3.23 g/plot, by three frames was 3.07g/plot, by two frames was 2.77g/plot, and by one frame was 2.68 g/plot. The 1000-seed in open pollination treatment weighted 2.95 g/plot and 2.60 g/plot in free-honey bee pollination. Maximum seed germination was recorded in four frames of honey bee (94.5%), followed by three frames (93.5%), open pollination (92.8%), two frames (92.2%), one frame (89%), whereas the minimum seed germination was recorded in treatments of free-honey bee pollination (83.5%).
