Then using a knapsack or hand-pump sprayer, spray it on your crops. To be effective, spray every 10 days. 20-30kg kernels can treat 1 ha.

Pls how much seed should we use in a liter of water? Or it doesn’t matter?

You can use 25g of peeled and crushed neem kernels (inner part of the neem seed) in a liter of water. Or if you are using the seed, use 50g seed per liter of water.

Any idea where neem seed can be bought?
