Miracle grow: Indian farmers smash crop yield records without GMOs

"What if the agricultural revolution has already happened and we didn’t realize it? Essentially, that’s the idea in this report from the Guardian about a group of poverty-stricken Indian rice and potato farmers who harvested confirmed world-record yields of rice and potatoes. Best of all: They did it completely sans-GMOs or even chemicals of any kind..."

"...What happened in Darveshpura has divided scientists and is exciting governments and development experts. Tests on the soil show it is particularly rich in silicon but the reason for the "super yields" is entirely down to a method of growing crops called System of Rice (or root) Intensification (SRI). It has dramatically increased yields with wheat, potatoes, sugar cane, yams, tomatoes, garlic, aubergine and many other crops and is being hailed as one of the most significant developments of the past 50 years for the world's 500 million small-scale farmers and the two billion people who depend on them.

Instead of planting three-week-old rice seedlings in clumps of three or four in waterlogged fields, as rice farmers around the world traditionally do, the Darveshpura farmers carefully nurture only half as many seeds, and then transplant the young plants into fields, one by one, when much younger. Additionally, they space them at 25cm intervals in a grid pattern, keep the soil much drier and carefully weed around the plants to allow air to their roots. The premise that "less is more" was taught by Rajiv Kumar, a young Bihar state government extension worker who had been trained in turn by Anil Verma of a small Indian NGO called Pran (Preservation and
proliferation of Rural Resources and Nature), which has introduced the SRI method to hundreds of villages in the past three years.
