In the Punjab, wheat and rice are grown in many areas, with the use of irrigation. This area is predominantly coastal, yet also has mountains called the Ghats, and the Vindhya mountains, where a number of rivers begin and flow down into the sea, with most of them entering the Bay of Bengal. The Western side of the Peninsula is higher than the East, with much of the eastern side being made up of flat, low-lying river deltas. This makes this area a good area for growing rice, which is its major crop. The climate in the Peninsula is more tropical than in the North, allowing the growth of poducts such as coconuts and nuts.
Fish is another major food source in the coastal areas.
There are many spices grown in the area of Kerala on the South West of the Peninsula.
