Background: Egyptian clover (Trifolium alexandrinum L.) is one of the most important annual, winter, multi-cut fodder legumes grown in northern India. Many a times, poor activity of pollinators cited for lower seed production in berseem. Therefore, an appropriate local food-based bee attractants need to be identified and their effectiveness in enhancing berseem seed yield needs to be assessed. Methods: The experiment was conducted to evaluate the significance of bee visit on yield parameters of berseem. In addition, the effect of attractant (jaggery and sugar at 10%) in enticing honey bees towards the berseem flower was evaluated at ICAR- IGFRI, Jhansi during 2017 and 2018. Result: Both the attractants (jaggery and sugar at 10%) are equally effective in drawing the Apis dorsata towards berseem and higher bee visits (8.75 and 8.54/m2/5 min) were recorded one hour after application. Maximum seed setting percentage was recorded in plots sprayed with jaggery (83.53) followed by sugar solution (82.58), which is significantly superior over farmers practice i.e. crop left for open pollination (74.86). Maximum seed yield was obtained from plots sprayed with jaggery solution (8.15 q/ ha). The bee visit had significant positive effect on seed yield (0.685*) and 1000 seed weight (0.671*).

The effect of different modes of pollination on quantitative and qualitative parameters of Egyptian clover, Trifolium alexandrinum L. was studied at Forage Section, Department of Genetics and Plant Breeding, CCS, Haryana Agricultural University, Hisar during 2012 and 2013. Maximum seed setting (81.5%) was recorded in A. mellifera pollination with an 8 frame colony (BP-8F) followed by 4 frame colony (BP-4F) (75.1%), open pollination (OP) (73.8%) and 2 frame colony (BP-2F) (71.5%). Maximum seed yield (2662.3 seeds) was observed in treatment BP-8F followed by BP-4F (2373.8), OP (2316.3) and BP-2F (2235.5). Still lower yield of 2103.0 seeds was found in hand pollination (HP) treatment that was significantly higher than the without insect pollination (WIP) treatment (1114.2). Minimum 1000-seed weight was observed in WIP (2.64 g). The seed weight of BP-4F (3.30), HP (3.20), BP-2F (3.17) and OP (3.03), the heaviest seeds were recorded in BP-8F (3.62 g/1000 grains) and it was at par with the treatment BP-4F (3.30 g). Highest seed germination per cent was recorded in BP-8F (94.7) followed by OP (90.7%). Lowest germination was found in WIP (84.7%). Though some work has been done on this aspect in India but comprehensive pollination studies has not been worked out.

Field investigations were conducted during the winter seasons of 1992/93 and 1993/94 to find the optimum sowing time and time of last fodder cut for the fodder and seed production of Egyptian clover (Trifolium alexandrinum L.). The delay in sowing from 1 October to 15 November decreased the green and dry fodder yields but increased the seed yields. Total green and dry fodder yields (of all cuttings) for 1 or 15 October sowings were significantly higher than the 15 November sowing in both years and 1 November sowing in 1992/93. Increase in seed yield from the 15 November sowing was greater than from the 1 and 15 October sowings. Straw yields followed similar trends. Delay in the last cut for fodder, however, increased green and dry fodder yields but decreased the seed yield. The percentage increase in dry fodder yield with each successive delay in last cut for fodder was higher than that of green fodder yield. The 11 April cutting date of fodder produced the highest green and dry fodder yields but the lowest seed yield. Two years mean data showed that the 2 March cutting date of last fodder gave the highest seed yield. It is concluded that higher seed yield of Egyptian clover can be produced by sowing on 15 November and giving the last fodder cutting on 2 March.
