Answer:
c)assertion is true but reason is false.
Explanation:
till the mid 1960's farmers didn't buy seeds from shops. they cultivated some crops and took some seeds for themselves and sold the rest of the crops in the market.
the seeds don't require less irrigation. they seeds wanted more water as of present day.farmers used cow dung and natural fertilizers like manures. because there is not such technology at that time to produce chemical fertilizers.this is explanation for assertion.
explanation for reason:
the same piece of land can't produce more grains than it was possible earlier because in present day farmers use chemical fertilizers like NPK (nitrogen, potassium, phosphorus) and dap. these are chemical fertilizers. so the same land can be used to produce more crops than in the mid 1960's.
