With all the experience in farming and that in runs in the blood in Punjabis, plus Punjabis are generally fairly literate (compared to some in other countries in Africa, Asia and S America), they should be doing better in farming. There's even Punjab Agricultural University
All things said and done, given the apparent gender disparity in Panjab, men will have to marry out. Otherwise go back to buying girls or sharing wives between brothers. That's some rank anti-Sikhi gundh!
I love growing myself (okay, on a small scale). It's murder even keeping a tiny bit of soil constantly replenished with nutrients in a sustainable way. I've achieved it after trying for years, with composting all food scraps and the grass and cardboard, and that's only on a miniscule scale. Worm farms help big time! I still have to buy a big sack of soil every year though.
There is something very spiritual and therapeutic about growing, no doubt about it! But when it's just a business......I don't even know if you get that? Panjab has literally ruined it's soil with 'modren', 'green revolution' techniques (more like Frankenstein style Guinea Pig failed experimentation on the food and soil of Panjab!)
That bull5hit green revolution was not sustainable.
