Is it possible to get maximum yield per plant by calculating fertilizer doses on individual plant basis? For example, hybrid eggplant yield 45 to 50 tons per hectare by applying 150 kg n, 125kg p, 125 kg k, at plant population 13500. Means per plant average yield 45000/13500=3. 33kg fruit. Is it possible to get maximum yield 10 kg per plant with proportionally adding extra npk 450n, 375 p, 375k doses with same plant population?
