Make A Bed/low-ribbing
The next step is to prepare a growing medium for your onions.
To create a bed for your onions, you must create low, mound-like ridges, particularly during the dry season.
Ensure that the beds are short and close to the ground so that the seed can receive the minimal amount of water required for growth.
Including Manure or poultry droppings
After you have completed the bed, the following step in soil preparation is to apply manure to your beds so that your onions will grow quickly and well.
You can add fertilizer in the suitable ratio, and if you don’t have enough money for fertilizer, you can use organic fertilizer.
Locate local poultry, collect its droppings, and apply them to your farm’s beds at least two weeks prior to planting.
Step 2: Start Nursing your onion seedling

After you’re done preparing the soil and farm, it’s time to grow onion seedling for transplanting. To do this, do the following:
Find a farm store near you and buy hybrid onion seeds.

You also need to get some dried bird droppings.
You mixed the wood shavings you got with the dry bird droppings you got and added a little water to make it moist.
Then, put this mixture on the nursery path or the trough you have to care for the seed.
Make ridges with this mixture by putting it in horizontal lines about 2 cm apart.
Then, put the hybrid seeds you just bought from the farm store in a random pattern on this tray and cover with a little bit of sand.
Start watering the tray in the morning and at night, but don’t water the lines where the onions are spread.
This is because onions don’t like a lot of water; you only need to wet the bottom of your line.
This should be done for 10 days. Most onion seedlings are alive and ready to be planted after no more than 10–15 days.
Step 3: Begin Transplantation
The next step is to begin shifting your onions to the farm bed you’ve prepared.
Plant the seedlings 1cm deep with no space between them on the bed if you want to harvest your onions when they are green.
If you want to harvest it while it’s dry, plant it 1cm deep and space it at least 2-3inches apart and 10-12inches between rows.
Take temperature readings throughout nursing and after transplanting.

In your onion farm, avoid excessive or clogged water.
To avoid onions bulb growing thick necks and excessive leaf, do not put fresh poultry droppings on the farm soil.

Thanks for the information. In your presentation, you said that onions don’t require a lot of water cx of the reasons highlighted. why then should we start planting onions in February when the month is characterized by a lot of rains, even march which comes immediately after February has a lot of rains especially in regions like the Luapula province of Zambia. Isn’t too much water in these months going to cause poor formation of bulbs and other issues?
Your response please
No, that was why we recommended planting on loose soil, not loamy or sticky soils that do not let go of water easily, why we recommend the rainy season was that, onions do not need much water, however, it requires water for survival which it might not have access to during the dry season.
