Question

why is rice a commercial crop in punjab and haryana and a subsistence crop in orissa ?

Answer 1

Rice is a commercial crop in Punjab because farm sizes in Punjab are typically large. Moreover, Punjab has extensive irrigation facilities and farmers in Punjab use high yielding varieties of rice.

On the other hand, in Orissa, farm sizes are small. Orissa primarily relies on rainfall for its agriculture. Oriya farmers use traditional varieties of seeds for growing rice. For such reasons, rice is a subsistence crop in Orissa
