Its a hit or miss in India. It isn't that the quality is vastly superior. You still get a produce from far away - and the fish is usually delivered on ice slab. The soil isn't that arable as you might expect, as the biggest chunk is loamy & alluvial soil of North India is exclusively wheat & sugarcane. Monsanto despite all its evils does a good job in Midwest. No similar equivalent in India unfortunately. Plus mechanisation rate is low because of land fragmentation. These are collective factors that make yield (qual + quant) a variable thing.

My dad grew his own vegetables. The only guaranteed fresh ones I ate :) Fun fact: Best mangoes generally are from Philippines. The Cebuano variety. Alfonso is mighty overrated.
