I dont remember any mention of Ginger banana intercrop in Sri.Palekars book. But banana is intercroped with cowpea+chilli+Marigold. Another is Marigold+Onion+Cowpea.
PS:I personally hate Ginger crop. The reason is it has made fermers too greedy. It affected me alot. Labours demand twice wages in ginger sowing season, pipes and fittings are sold at high price. Cow manure are in high demand and is sold at premium price… so on.Around me farmers are stopping paddy and starting ginger. in coming days we may have to eat ginger in place of rice.
We are in touch with a consultant who is following Sri Subhash Palekar’s theory plus his own theory and claims to be successful. I have searched in the internet and found that (as Mr. Saravanan also suggested) intercrop -Banana+Ginger+Turmeric is good. Of course, we have grown Marigold+cowpea, sans Onion.
I didn’t know that ginger is grown that much! Do you suggest to go for turmeric instead, as it has buyers in the form of medicinal companies? I am personally in touch with one such buyer for turmeric.
