Thanks jim I think you have done nice research about my area, Coimbatore is quite dry it is an industrial area but if u take the states of tamilnadu and kerela they are the rice buckets. The major crops are rice,sugarcane and spices and mostly we depend on the monsoon for water. There are places people still use bullocks for preparation of land for cultivation I think we are still light year behind america on using mechanization in the farm and it is proving to be a necessity In this period with shortage of manpower in agriculture. People here have as low as 1 hectare of land and cultivate different types of crops it proves to be very challenging to get desired agricultural output if the cultivation and harvesting practices change on every hectares of land.
