Effect of N, P and K on growth, yield and quality of ber cv. Umran

Four levels of N (0, 250, 500 and 750 g/plant) in combination with three levels each of P₂O₅(0, 250 and 500 g/plant) and K₂O (0, 50 and 100 g/plant) were applied to ten year old plants of Umran ber. The growth, yield and quality parameters improved significantly with added nitrogen. The application of phosphorus influenced all the parameters significantly except plant height, spread and fruit acidity. Potash application caused very little or no effect on growth and yield parameters. The treatment combination consisting 500 g N, 500 g P₂O₅ and 50 g K₂O/plant was found best for obtaining maximum yield.
