Mentha & water
One-time watering of mentha crop needs 8 to 10 hours of water pumping (from an electric pump)
It requires 50 lakh litre water per acre to produce 30 to 35 litre of mentha oil (average production/acre)
On the contrary, it requires only 50 to 150 litre of water for production of one kg of wheat — the principal crop of Bundelkhand
