Effect of sprays of bee attractants on qualitative and quantitative yield parameters on seed onion crop (Allium cepa L.)

Abstract

A field experiment was conducted to study the effect of sprays of indigenous bee attractants on qualitative and quantitative parameters of N-2-4-1 variety of seed onion crop (Allium cepa L.). Among different treatments, sprays of bee attractants Jaggery solution (10%) was found to be the most effective as it recorded significantly highest number of seed per umbel (843.25), increased in seed set over control (31.60%), test weight (4.19 g/1000 seeds), seed yield per plot (753 g), seed yield per hectare (1145.83 Kg), germination (86%) and lowest deformed seed (6.95%). However, the parameter number of umblets per umbel is non-significant to the treatments.
