hello sir
SEED RATE
For common big onions, 8-10 kg seed is sufficient for raising seedlings for one hectare, accomodating 100-110 beds of 3m X 0.6m size each. For broadcasting directly in the field or sowing in the rows, 20-25 kg seeds is enough for a hectare. For multiplier onions 10-12 quintal bulblets are required for planting one hectare.
LAND PREPARATION
The field should be ploughed to a fine tilth by 4 -5 times with a sufficient interval between two ploughings.
TRANSPLANTING
Seedlings are usually transplanted in flat beds. Transplanting on raised beds or on both sides of ridges is, however, better for kharif or rainy season crops. Flat beds of 1.8 m wide and 7.2 m length depending upon level
SPACING
The spacing depends upon the variety and size of bulbs. In common big onions an spacing of 15 cm from line-to-line and 10 cm from plant to plant is ideal.
HARVESTING
Harvesting takes in 45-90 days from field setting for green onions and 65-150 days for bulb depending upon variety / types. Bulbs are considered to be mature when the neck tissues begin to soften and tops are about to abscise and decolourise. Development of red pigment and characteristic pungency of variety are also important harvesting indices of onion.
