Onion seed production | onion seed farming :- Soil and climate requirements :- Well drained medium to heavy soil. PH range of 6.5 to 7.5 are good for onion seed production. Flowering initiation in onion takes place at a comparatively cooler temperature(15 - 25 degree celcius). Higer temperature are favourable only for seed ripening and maturity. Low temperature at the time of bulb planting (nov - dec). Moderate temperature during stalk development, flowering and seed setting (january - feb). Warm temperature at seed maturity and drying (march - april). Field preparation and planting :- A deep ploughing and incorporation of well decomposed FYM @ 20t per hectare creates good soil tilth. Ridges and furrows are common planting method. Selection of mother bulb :- The 5m distance should be maintain from other onion field for avoiding contamination of bulbs of another variety.

The initial infestation of shoot and fruit borer during 4th week of august at 47 days after transplanting and peak incidence was observed during 2nd week of september after 114 days of transplanting and thereafter declined gradually with rise in temperature. Damages :- The damage to the fruits start soon after transplanting and continuou...
