Abstract:
Field experiment was conducted during 2022-23 at Saidapur farm, UAS Dharwad. The experiment was laid out in Randomized Block Design with three replications and Twelve treatments. Foliar spary of nano urea and boron take place at 45 & 60 days after planting the onion bulbs (DAP) at different levels in onion seed crop. Results reveled that among different treatment, T₉ (RDPK+50% Nitrogen (Basal) +50% Nitrogen through nano urea (25 % N each) + Borax (0.5%) at 45 & 60 DAP) recorded higher plant height at 120 DAP, chlorophyll content at 90 DAP, number of umbels per plants, length of the scape, width of umbel, seed yield per plant and seed yield per hectare compared to control.
