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.

Okra is mainly propagated by seeds and has duration of 90 - 100 days. Flowering is continuous after 30 - 45 days of sowing. Okra requires a long, warm and humid growing period. It is sensitive to frost and extremely low temperature. For normal growth and development it requires 24 degree celcius to 28 degree celc...
