The concept of farming was started 10000 years ago in the Vaidic age. At that time the chemicals were not there but they can protect the plant their plant, they can grow their food and can feed their people. After independence as well as partition the amount of land divided but the population of India do not decrease at the same ratio of the land. As a result a food scarcity arise. After World War 2 the countries who stop their business of weapons they started the business of chemical fertilizer, and they choose the north-eastern trance Gangetic plane as their place of extension. The HYVP (High Yielding Varity programme) so called green revolution started. The high yielding variety needs more fertilizer more water as a result today north-eastern trance Gangetic plane become a unfertile land.
Is it really needed? After 1000 years of slavery under different rulers we forget that our sages also doing farming, one India was well known for its farm products like spices fruits etc. The rulers put their view on agriculture in our brains and we forget our own technologies.
From the age of Rigveda we started farming. Rigveda the oldest composition, has several verses describing the profession of farming. For example, book 10 chapter 34 and verse 13 of Rigveda contains the divine massage about agriculture.
Other old compositions are-
1. Krishi Parasara of the sage Parasara(c.400BC)
2. Kashapiya Krishisukti of sage Kashapiya(c.800BC)
3. Brihatsamhita of Barahamihir(600 AD)
4. Vrikshayurveda by Surpala(c.1000AD) etc.
