Chickpea (Cicer arietinum L.) is an ancient crop that has been grown in India, the Middle East and parts of Africa for many years. It may have been grown in Turkey nearly 7,400 years ago. Much of the world's chickpea supply (80 to 90%) comes from India where poor soil, use of unimproved varieties and low rainfall results in yields averaging about 700 lb. I don’t know if it’s intensive or extensive. I’m really sorry.
