Soil and climatic requirements:
Well-drained sandy loam soil is best suited. The optimum pH range would be 6.0 – 7.5. Water logging and alkaline soils adversely affect the growth & development of plant & bulb. Onion is a cool season crop. It is grown during winter and harvested before the real hot season begins. But it grows well in mild season without extremes of heat and cold.
Varieties: At the following link the seed varieties can be viewed. Few of them are Nasik Red, Prerana,XP Red onion, Gulmohar, Prema Onion, Marshal onion ,..etc.
Planting time: May - June – July; August - September – October, and January - February.
Seed rate: Seedling transplanting: 2 - 2.5 kg/acre; Direct sowing: 8 – 10 kg/acre; Broadcasting: 20 – 25 kg/acre
Spacing for seedling transplanting: 15 cm x 7.5 cm ; For direct seeds sowing: 30 cm x 30 cm
Plough the land to get fine tilth by 2 – 3 ploughings.
Nursery preparation: Prepare nursery beds of size 7.5 m length, l.2 m width and 10cm height. Add 3 - 4 basketful of FYM/compost, 200g PSEUDOMONAS FLUORESCENS (Spot) and Bio activator mixtures (Ecohume Gr granules) per bed.

Mix all the above products well & incorporate into the soil. Sow the seeds in the rows of 7.5 cm apart. Irrigate the beds immediately. Again after 10 days add 0.5 kg/bed 15:15:15 (N: P :K). Seedlings will be ready for transplanting within 6- 8 weeks after sowing. Then transplant the seedling at 15 cm x 7.5 cm spacing.
Direct seeds sowing: After thorough land preparation directly sow the seeds in a row of 30 cm apart and 30 cm between plants.
Broadcasting: Broadcast the seeds after land preparation and Basal applications. Thinning may be required at highly populated dense growth of the onion saplings.
Recommended dose of Fertilizer Application: NPK – 50:30:40 kg/ per acre per crop
6 to 8 ton of FYM applied at the time of soil preparation per acre along with 20 kg N, 20 kg P2O5 & 20 kg Potash /acre should be applied along micro nutrient 5 kg Zinc high Aries Multi Micronutrient fertiliser + 15 kg Calcium nitrate.
Remaining 20 kg N + 10 kg P and 20 kg Potash to be applied after a month of sowing and another 10 kg of N 15-20 days before harvest.
