Question

how can you say that now india is practicing subsistence farming

Answer 1

Subsistence agriculture is self-sufficiency farming in which the farmers focus on growing enough food to feed themselves and their families. The output is mostly for local requirements with little or no surplus trade. The typical subsistence farm has a range of crops and animals needed by the family to feed and clothe themselves during the year. Planting decisions are made principally with an eye toward what the family will need during the coming year, and secondarily toward market prices. Tony Waters[1] writes: "Subsistence peasants are people who grow what they eat, build their own houses, and live without regularly making purchases in the marketplace."

Answer 2

then the answer is no, because not everybody in the entire population know how to farm on a subsistence level. In fact, the majority of the entire population wouldn't have any farming skills whatsoever, much less on the level it would take to feed themselves year round and in proper nutritional balance.
