Sukuma Wiki is one crop that is bound to give you plenty of returns with a small initial investment. I happened to farm the vegetable during one of my long holidays in campus. I started with Kshs. 15000 on half an acre piece of land. I could say that I made a pretty Kshs. 100000 by the end of 4 months. The good thing about kale farming is that it does not require a lot of inputs. I would say that one only needs a good source of water and timely spraying. I would spray once per week after every harvest. I would then take my harvest to the nearest market where I would deal directly with the consumers. I realised that it was the best method since if you involved middlemen you would make big losses. I would recommend kale farming to anyone looking for a simple stress-free farming.
