Prawns and duck feeding are done in the intervals of cultivation. Cow dung and green leaves are also used here as manure
Dear Ram Niwas Choudhary many thanks for posting this very important technical question which will certainly be of broad interest to many other RG members as well. As an inorganic chemist I'm absolutely not an expert in this area of research enough to give you a qualified answer. However, I can suggest to you that you have a look at the following relevant article:
Organic Farming in Rainfed Agriculture : Opportunities and Constraints
The article is freely available on the internet as public full text (please see attached pdf file).
I hope this information is useful. Good luck with your work!
Both conventional and organic farming is practiced under rainfed conditions even in the difficult mountain ecosystems. One has to mainly worry about supply the soils with required nutrients by means of farm-yard manure, compost or other organic fertilisers like rock phosphates, silicon; and try mixed cropping to increase diversity to reduce crop infestation by pests.

Organic farming has been tried in rainfed areas
