Which is the best fertilizer for sukuma wiki?

Farmers ask all the time.

Based on my 15 years growing sukuma wiki,  the best fertilizer for sukuma wiki (that will give you maximum returns) depends on the stage of growth of the kale.

Let me explain:

Kale/sukuma wiki has to grow through:

  1. The seedling stage (4-30 days old)
  2. Juvenile stage (31-45 days old)
  3. Active productive growth (46-120 days old)
  4. Old age/senescence (121+ days old)

Each of these stages requires a fertilizer which is best for kale.

And that is what I am going to discuss briefly below.

The Best  Fertilizer For Sukuma Wiki at The Seedling Stage:

When the kale seed is 0-7 days old, it does not require any fertilizer.

However, as the seedling increases in height and size, it needs a little nitrogen but not excessive.

Therefore the best fertilizer to use when a kale seedling is 8-30 days old is UREA!

Best Fertilizer for Sukuma Wiki at the Juvenile Stage:

This stage of growth lasts from day 31-45.

It is at this stage that you’ll transplant the kale seedlings to the open field.

During transplanting, the best fertilizer for Kale is DAP.

DAP promotes strong and fast root development so that the plant is able to resist drought and other harsh environmental conditions.

Strong and numerous roots means the plant will be able to feed itself with water and nutrients.

As you use DAP, don’t forget to add manure.

Manure helps to improve soil texture, soil micro flora, and water retention capability.

Best Kale fertilizer For Active productive growth (46-120 days old)

At this age, the plant is at its prime age.

It is growing rapidly, producing many leaves and expanding in size and height.

During this stage, give top dress the plant with either NPK 17:17:17 or NPK 20:20:20

These compound fertilizers will give the plant balanced nutrition to sustain this rapid growth.

As you top dress the plant, remember to use foliar feeds rich in macro nutrients and micro nutrients.

Using foliar feeds will help prevent the development of deficiency symptoms!

NPK 17:17:17 is the best fertilizer for kale that is actively growing

Best Kale Fertilizer For  Old age/senescence (121+ days old)

When Kale gets to this stage, its productivity slows down.

It no longer produces lush leaves as it did before.

If you don’t take care of the plants at this stage, they won’t live past 6 months old.

And that would be a tragedy because you won’t have maximized the yields kale is capable of giving per acre.

So What is the best fertilizer for this stage?

To spur active growth, the best fertilizer is UREA.

When you give the plants urea, irrigate the plants for at least 1 week without harvesting to invigorate the plants.

After that, top dress with NPK 17:17:17 or NPK 20:20:20.

Don’t forget to boost the plant with foliar feeds containing micro and macro nutrients.

Do this, and you’ll harvest kale for over 9 months without any significant reduction of yield.

  • Plant growth periods that require relatively high Nitrogen levels e.g. during periods of vegetative growth.
  •  Directly after harvest when nutrients need to be stored for the next season.

It is ideal for the vegetative growth stage of kale/ sukuma wiki (e.g. shortly after establishment)

When you apply it at that stage, it enhances formation of adequate foliage for photosynthesis.

Since this plant has high Nitrogen content , plants have healthy vigorous growth, strong root development, dark green foliage, increased seed/fruit formation and higher yields.  

EASYGRO Vegetative is compatible with most agricultural remedies.

However, avoid lime sulphur, white oils and certain copper formulations.
