Effect of spacing and date of planting on the growth and seed yield of onion (Allium cepa L.)

Singh, M. P.; Rathore, S. V. S.; Mangla, J. L.

Onion bulbs, Patna Red, were planted 10 - 40 cm apart in rows 30 cm apart, at 2-weekly intervals between 1 October and 12 November. Total seed yields were highest at the closest spacing, with the 2 early planting dates, but seed yields/plant were highest with wide spacing.
