Effect of abundance of pollinators on yield parameter of Niger, Guizotia abyssinica (L.f.) Cass. Grown at different dates of sowing

HR Kachhela and JJ Pastagia

The experiment on effect of abundance of pollinators on yield parameter of Niger, Guizotia abyssinica (L.f.) Cass. Grown at different dates of sowing was undertaken at college farm of Navsari Agricultural University, Navsari during Kharif, 2016. For the purpose, crop was sown at seven different dates and observations on number of pollinators visited during flowering period as well various yield parameters were recorded from the crop grown at particular dates of sowing. The mean number of pollinators visitation was higher on the crop sown on 30th July (15.36/m2/5 minute) which was statistically at par with the crops sown on 10th August (14.56/m2/5 minute) followed by 20th July (13.39/m2/5 minute) and 10th July (12.89/m2/5 minute). The crop sown on 30th July recorded significantly higher Seed yield per hectare (625.90 kg) which was at par with the crop sown on 10th August (531.56 kg). Positive and significant relationship was observed between the abundance of pollinators and yield parameters viz., number of seeds per capitulam (r = 0.667), seed yield per plant (r = 0.806) and seed yield per plot (r = 0.815). It indicates that the abundance of pollinators or increase in pollination activity at particular date of sowing increased the seed yield of Niger.
