I have a banana farm and applied about 25kilos of cow dunk (cow manure) on each plan. I after 1 month i cant see effect. I believe if has to decompose first. I cannot wait for that because the growth of the plants are very slow.

I want to apply artificial manure.
I have 2 types available around my local market.

1. Urea (White Salt-like small balls)
2. NPK 15:15:15 (Round Brown balls)

During my research on the internet, i found out that Urea is 46:0:0 NPK.
I am guesing that the NPK 15:15:15 can do the work of Urea.
Now the question is, should i use Urea? or NPK? or both until the cow manure decomposes?

Thanks

Use the 15:15:15, you want a balance of nutrients, not just nitrogen. The balanced fertilizer will supply nitrogen in addition to phosphorus and potassium, both of which are also very important.

However, if you are trying to speed up growth, fertilizer might not be the issue. Are the plants getting enough water? If they are not getting enough water, they will grow slowly, but fertilizer will not speed them up.

He is just guessing NPK ratio. There are dozens of combinations.
Be careful with Urea, it can burn plants in a hip.

We give ours 15-15-15, about a kg per year per pseudostem. Distributed every two weeks with additional folear spray feeding of 20-20-20 during the dry/irrigation months. Once they are fruiting we give them extra amount of 0-0-50 sulfate of potash to enlarge the fruit. So about 4g every two weeks per pstem, of each type of fertilizer. This is working for us.

great looking plants!

is this the same field with the bananas with the browning leaves?

many members have issues with browning leaves and would love to see what they look like now.

15-15-15 Bananas are heavy feeders. Also add lots of composted organic matter.

Thanks for the compliment, much appreciated in view of all the hard thinking and worries involved in this project.

The field that had browning leaves is recovering, I posted an update today here Why are the leaves looking yellow? - Page 2 - Bananas.org

Thanks for the post. I want to give a foliar to the plants but am not sure i can get 0:0:20 fertilizer in my local market.
Can i use the 15:15:15 and if yes, how will i go about with the mixture?

We do use a special mix. There are brands like Haifa that specialise in folear feeding mix. We mix 500g of the quickly dissolving small crystals mix with 200 liters of water for spraying. I investigated the option of using standard pellets but could not find any information on dosage. Also dissolving into the water would also be a problem. However, a 25 kg bag of specific folear 20-20-20 fertilizer costs the same as a 50 kg bag of good brand 15-15-15 pellets.
All I can suggest is to try dissolving one kg of your pellets into warm water, then mix into 200 liters of water and test spray. You should be seeing results quite quickly. Keep us informed about results.
