Effect of nitrogen, plant spacing and size of mother bulb on growth and yield of seed crop of onion (Allium cepa L.)



Effect of nitrogen, plant spacing and size of mother bulb on growth and yield of seed crop of onion (Allium cepa L.)



Indian Journal of Horticulture 29(2): 185-189



Onions were grown for seed from mother bulbs weighing 20, 35 or 50 g, spaced at 20, 35 or 50 cm and given 20, 40 or 60 kg/ha N. The seed yield was greatest when 50-g bulbs were used at the closest spacing with N at 40 kg/ha. The treatments did not influence seed weight or the number of days from planting to the breaking of the scape or to flower initiation. However, the number of days from planting to 50% flowering was least with the largest bulbs.
