ONIONS
SITE FOR PLANTING ONIONS:
1.) Accessibility to good roads, transportation facilities, and market
A good farm-to-market road is practically essential. Bad roads limit the size of loads, increase wear and tear, and cause crops to be bruise. 2.) Well-drained areas
A gently sloping land is a good site because it allows for efficient water drainage. The site should not have any depression where water may accumulate. 3.) Soil fertility
Spice crops can be grown in almost all types of soil. However, they thrive best in loose, friable, sandy loam soil rich in organic matter. 4.) Climatic conditions
Most spice crops grow best under warm humid climates but some grow in dry environments. Determining what kind of spice crop to grow in a particular area should be done beforehand. 5.) Rainfall

The amount of rainfall is important because spice crops do not grow well in areas with excessive rainfall. Instead, they grow faster in places with direct exposure to sunlight.

The onion plot should be plowed, harrowed, and left in good tilth. The surface should be well worked and smooth. For every kilogram, prepare a 1x10 meter plot. Prepare five plots and five kilograms of seeds for every hectare of planting area.

Sow the seeds thinly and evenly then water the plot. Cover them with a thin layer of pulverized soil to avoid exposure to sunlight. Keep the soil moist by watering it every week with ammonium sulfate. Seedlings are grown for 30-40days. As the onion matures, gradually decrease water supply to promote proper bulb ripening. Stop watering when the tops of onion start falling over as they are almost ready for harvesting. Onion’s keeping quality is longer when it is fully...
