ABSTRACT
In present year, demand of onion in domestic and international market is increasing day by day but non-availability of good quality seed is limitation for profitable seed production programme of onion. Hence an experiment was conducted to study the effect of dates of bulb planting and application of foliar nutrition on plant growth and seed yield of onion during the Rabi season 2015-16 and 2016-17. The experiment consisted of five dates of bulb planting with four application of foliar nutrition. The experiment was laid out in Randomized Complete Block Design (RCBD) with two factorial concepts. The experimental results revealed the significant effect of dates of bulb planting and application of foliar nutrition on growth and seed yield. Significantly highest values were recorded in the growth parameters like plant height (45.83 and 51.17 cm), number of leaves (29.50 and 36.00) @ 40 and 60 DAP and less plant disease severity (11.48 %) and seed yield parameters like number of umbels per plant (8.13), umbel diameter (8.13 cm), number of seed per umbel (918), seed weight per umbel (4.98 g), seed yield per plant (16.33 g) and seed yield per hectare (741.74 kg) were recorded by planting the bulbs on November-1st coupled with application of multi micronutrient mixture at 0.25 per cent (D3T3) and significantly the lowest was recorded by December-1st planting with without spray (D5T4).
