A few words about this book on the ‘’Magnitude of co-operative credit Defaults by Farmers in YSR District of Andhra Pradesh”(with references to primary agricultural co-operative societies). This book is focused on agriculture credit structure in India as well as YSR District and reasons of agricultural credit defaults in primary agricultural co-operative societies in YSR District. Give the suggestions to reduce the agricultural credit defaults and enhance the agriculture credit supply in rural areas. In my hopes book is used to co-operative students at the training centres the students of commerce and co-operation in the colleges and universities would be benefited in understanding through this humble endeavour of mine the techniques of co-operative societies for providing where withal to the million of un organised poor peasants, I shall feel more than rewarded for this venture on my part.
