Influence of nitrogen, phosphorus and potassium on yield and physico-chemical properties of phalsa.

摘要

The effects of N (100, 200 or 300 g per plant), P (25, 50 or 75 g per plant) and K (50, 75 or 100 g per plant) fertilizers on the performance of phalsa (Grewia subinaequalis) were studied in Faridabad, Haryana, India. The sources of N, P and K were calcium ammonium nitrate, single superphosphate and muriate of potash, respectively. Almost all the fertilizer combinations improved the yield and quality of fruits over the control. The application of 300 g N + 50 g P + 75 g K per plant resulted in the greatest fruit weight (1.09 g) and yield per plant (4.12 kg per plant). N, P and K at 200, 75 and 100 g per plant, respectively, registered the highest total soluble solids content (22.7%) and organoleptic rating (9.7 for a 1-10 scale).
