Study on the effects of planting geometry, bulb size and planting dates on the growth and seed yield of onion (Allium cepa L.)



Study on the effects of planting geometry, bulb size and planting dates on the growth and seed yield of onion (Allium cepa L.)



Progressive Agriculture 2(2): 148-150



The effects of bulb size (4.0-5.0 or 5.5-6.5 cm), spacing (45x30 or 60x30 cm) and planting date (14 October, 24 October, 3 November, 13 November or 23 November) on the performance of onion Kalyanpur Red Round were studied in Kalyanpur, Kanpur, Uttar Pradesh, India during the rabi season of 1998/99. Large bulbs (5.5-6.5 cm) planted on 3 November at a spacing of 45x30 cm resulted in high number of umbels per plant and highest seed yield (8.20 quintal/ha).
