What Is Involved In Onion Farming?

Onion farm

Onion farming is a highly profitable business that has been practiced for centuries in many parts of the world. 

The main ingredients of any good onion crop farming are healthy, rich, and deep soil and a strong, sturdy (or hardy) and healthy plant. 

There are many different types of onions and many different ways to cultivate them.

How To Set Up An Onion Farm In Kenya

Setting up an onion farm in Kenya is not a difficult job. All you have to do is find the right partners, buy the right seeds, and find a good place to start, you can do onion farming in Kenya successfully.

When it comes to the partners, find an onion grower who can help you with the whole process. 

You can also find onion farmers who are willing to sell their products as wholesale products. 

You can also search for onion farms in Kenya that sell onions through an online marketplace like African Seeds.

Once you have your partners, you then need to find a good place to farm your onions. You can either buy or rent your land. 

You can also find partners to help you find a good source of finance, depending on your needs. 

Then you can also choose to use a leasing option to get your land leased. 

The most important part of setting up an onion farm is finding the perfect climate for your onions. 

An onion that is grown in the wrong climate won’t produce good quality onions.

Climate requirements

A perfect climate for an onion farm is warm temperature and low humidity. 

The temperature for your onion farm should fall between 26 and 30 degrees Celsius. 

If the temperature is too high, the onions won’t be able to produce properly. 

If the temperature is too low, then your onions may be killed by the frost. 

Soil requirements

You can grow onions in any type of soil, but you need to make sure it has the right nutrients. 

For your onions to grow properly, the soil should have a pH level of 6.0 or below. It should also have a clay content of 2-3%. 

The ideal soil texture for onion farming is loam with a texture like grits. You can also add compost or manure to increase the nutrient level in your soil. 

You can also purchase soil testing kits or visit your local extension office to find out the soil quality of your land. 

If you don’t have good soil, then you won’t be able to grow high-quality onions. It is important to remember that you can’t just plant onions on any soil. 

You need to find good, fertile soil for your onions to grow well. 

Land preparation

When you first buy your onion farmland, you will need to prepare the land. 

This includes removing weeds, digging out the earth, and adding organic matter to your soil. 

You should also remove stones or any other rocks that are on your land, as they can block the water flow. 

When you buy your land, ask the seller how they prepared the land before and make sure that the same process is followed on your land. 

You can also plant maize, sorghum, or legumes alongside your onions. These crops help in yield and soil fertility.

Seed rate, treatment, sowing season, & sowing method

The seed rate refers to the amount of seed you’re planting in a specific area. 

The best way to determine the seed rate for your onion farm is to plant some onions and then count the number of onions that sprout from the seed. 

You can also use a seed rate calculator to help you with this. The best way to plant your onions is to sow them in rows. 

This way, you’ll be able to easily manage the crop. You can sow the onion seeds on the 15th day after the planting date. 

You can sow the onion seeds in rows 2.5 to 3 feet apart. But you can also sow the onion seeds in transplant beds. 

This way, you’ll be able to easily harvest the onions. If you want to produce high-quality onions, you will need to sow the seeds at the same depth and spacing. 

You can sow the onion seeds in a drum of soil with a depth of 5-6 inches and you can also sow the onion seeds in a plastic tray filled with soil.

Irrigation

To produce high-quality onions, you need to provide your onions with adequate irrigation. 

This can be done through sprinklers or water channels. You need to water your onions regularly to ensure that they don’t dry up. 

If they do this, then they will be killed. You can also use a rain gauge or a hygrometer to determine when to water your onions. 

Make sure to water your onions at the right time to ensure that they don’t fall behind in the growth cycle.

Weed control

You will need to control weeds on your onion farm. 

If the weeds are left unchecked, then they will consume all the available nutrients in your soil, which will affect the onion’s growth. 

You can use a weed controller to control the weeds in your onion farm. 

If you don’t want to use a weed controller, then you can use a manual weed pulling machine. This will help to remove weeds from your onion farm. 

You can also use a ground cover to keep the weeds at bay. 

These coverings can help you to manage the soil, block sunlight, and also provide protection to your onions.

What Is The Ideal Soil Ph For Farming Onion In Kenya?

The ideal soil pH for growing onions in Kenya is between 5.5 – 6.5. 

This is because, at this level, the amount of available magnesium available in the soil is sufficient to make up the entire soil profile. 

This is the “magic” pH level where most of the nutrients are stored in the soil. 

Getting too low or too high of a pH can result in nutrient-poor soil that is difficult to grow onions in.

3 Steps You Can Take To Increase The Soil Magnesium Level In Your Garden

The first and most important step to increasing the soil magnesium level in your garden is to increase the water infiltration rate. 

This will result in a higher concentration of magnesium in the soil and a more favorable environment for growing onions. 

Soil that is too dry is very easy for plants to grow in and can have a large negative impact on the overall health of your garden. 

In order to maximize the water infiltration rate in your garden, you can:

1. Place a water-conserving device near the soil line. 

This will divert water from the ground toward the upper layers of your soil where it can be more effectively absorbed.

2. Place organic matter (such as grass clippings, leaves, or a mulch of your choice) on the surface of the soil where water infiltration is expected to occur. 

This will help retain the moisture in the soil and prevent it from evaporating too quickly.

3. Apply a water-soluble fertilizer (such as a Fertilizer For Garden Or Home) when the soil is too dry and the risk of yield loss is high.

How To Care For Onion Plants

Growing onions is a fun hobby, but it requires a lot of care. You need to take care of the plants in three critical areas: – 

Watering – You can easily kill your onion plants if you don’t water them properly. We recommend you water your plants when the soil is almost dry and the leaves droop. 

Fertilizing – Fertilizing is essential for all types of vegetables and can be done through organic fertilizers or blends.  

Caring for the pests – You can grow onions in almost all places, but there are certain places where it is not advisable to do so. 

We recommend you grow your onions in an area that is away from your house as there are certain pests that can easily damage your plants. 

You can prevent pests from harming your plants by regularly spraying your tomatoes.

Common Onion Diseases
