Explanation:

As per the Agroclimatic zones of India climate of north Indian states is not suited for rice cultivation. Rice needs high temperatures of above 250 Celsius and a rainfall of above 100cm. The north Indian region has high temperature during summer season, but rainfall is only 50-60 cm i.e. way below the desired level.
The north Indian region being the beneficiary of Green Revolution practices input oriented agriculture leading to high yields for all crops including rice.
In South India, the pest infestation is higher due to warm and moist climatic conditions. But the north being dry and hot during summers prevents pest infestation.
High MSP is also a reason that promotes the cultivation of rice despite unsuited as per agro-climatic conditions
