Explanation:

• Cropping Pattern of a region is an outcome of long term agricultural practices, social customs and traditions, physical conditions and historical factors.

Changing crop pattern in India is as under:-

• Food crops vs non-food crops: At the time of Independence, more than 75 percent of the total area sown in the country was devoted to the production of food crops. Gradually with the commercialization of agriculture, farmers in India have started shifting areas to non-food crops. Now, the relative share of area under food crops has declined from 81.2% during 1950-51 to 72% during 2014-15. Hence statement 1 is not correct.
• There are mainly three cropping seasons in India (i) Kharif (ii) Rabi (iii) Zaid. Till recently, Kharif crops have been contributing to the large share in crop production in India. But this dominance is on the decline. The share of Kharif has declined from 71 percent in the 1970s to 49 percent in 2003-2004. This makes a significant change in Indian agricultural practices after the Green Revolution. Hence statement 2 is correct.
• The total foodgrain output in 2017-18 was 284.83 million tonnes, including 144.10 million tonnes from the rabi season. This change is important because it would lessen uncertainty in crop production, as Rabi crops are more reliable than Kharif ones. The Kharif crops are not reliable because they are mostly dependent on rainfall. Most parts of India get rainfall from monsoon which is unreliable. Contrary to this, mostly Rabi crops in India are raised on irrigation which is comparatively reliable.
