Watermelons do well in hot and even dry areas. Watermelon is a warm season crop but requires water in the first few weeks of growth.

Irrigation should stop when it starts producing fruits. The less the water the crop gets as it develops, the better, as this increases the sugar content and concentration in the fruit, making it sweeter.

There are many varieties of watermelon in Kenya.

Sukari F1: It is the most widely grown watermelon variety in Kenya. It matures between 80 to 90 days. The fruit is oblong with an average weight of seven to eight kilogrammes. The rind is light green with dark green stripes while the flesh is red, crispy and firm.


The total soluble salt is approximately 12 per cent.

The thick rind is good for long-distance transport and has a yield potential of 25 tonnes per acre.

Asali F1: The fruit is green with rinds that are characterised by strips of green and dark green running down its sides.

The crop takes a minimum of 85 days or three months to mature. The fruit is large — weighing eight to 10 kilogrammes. It is succulent with a sweet red flesh.

This type of watermelon has a very high yield potential of up to 40 tonnes per acre.

It is resistant to anthracnose and fusarium wilt.
Andaman 631 F1: The rinds are green with no patterns on the elliptically shaped fruits. This variety of watermelon will do well in areas with relatively low rainfall.

It can be grown in greenhouses and is not affected by the limited sunlight either. The fruit has an average weight of eight kilogrammes.

If well-managed, the harvest per acre is 30 tonnes.

The fruit has flesh that is a deeper shade of red than other watermelons and is also sweet.

It takes a minimum of 80 days to mature. The vines for this variety are very strong. Farms on a slope will not have a problem when the fruits become larger over time.

Sweet Melon Galia F1: It has a unique green flesh inside and is sweet-tasting as well.

The rinds are brown and yellow with no definite pattern.

The yield per acre for this variety is about 25 tonnes. This is the smallest variety of watermelon available, with a fruit averaging two kilogrammes, though some are as low as a kilo.

It also takes a relatively shorter time to mature. In just 65 days, your crop may be ready. This, however, may extend up to 90 days.

The number of fruits per acre is relatively higher, meaning harvesting will be more labour-intensive.

All these varieties are available at seed companies like Amiran Kenya and Kenya Seed.

Hi. I am from Malindi, Kilifi County. I have a diploma in general agriculture and extension services. How can I be an intern in a company?

Thank you.

Felix Mghanga Mwakera

You must be aggressive when it comes to searching for a job. You should be making applications and sending your resumé to agricultural farms, companies and county governments.

There are many opportunities in agriculture. You can get an internship but you have to apply for it. You have not given us your contact.

How does one contact you if there is an opening?

Hello. I have a mature date tree that needs pollination. Please help me get in touch with any date farmer.

Robert Otim, Ra'anana, Israel

Date trees produce male and female palms. This therefore means that pollination has to be done manually by hand.

Male palms produce bigger flowers than females. That is how the two can be distinguished.

Pollination is done by cutting the male flowers and dusting the pollen onto plastic containers.

The pollen is then sprinkled on the flowers of the female date palms.

Kutch-Kibwezi is a commercial date farm in Makueni County.

You can plan to visit it and learn more on date pollination.

Kindly contact the farm through [email protected]

Hi, I would wish to start growing chia but I am not sure if a seedbed is necessary. Must I plant the seeds on virgin land? Is there a ready market for chia seeds? How long does the crop take to mature?

Derrick Kisia, Trans Nzoia

Thank you for your interest in chia farming. Chia seeds are directly planted on the farm and you don’t have to grow them on virgin land.

Many farmers grow chia without using pesticides or inorganic fertiliser, since the crop is resistant to pests and diseases.

Chia takes three months to mature. The demand for chia seeds is increasing as people are now aware of its immense health and nutritional value. The seeds are in demand locally and abroad.
