Effect of phosphorus and potassium on growth and flowering of Persian buttercup

Abstract

Different growth parameters were recorded for Persian buttercup grown in pots to evaluate various doses of phosphorous and potassium. The potted experiment was laid out in Completely Randomized Design (CRD) with three replications with following doses of potassium (0, 100, 150 and 200 mg/pot) and phosphorus (0, 50, 100 and 150 mg/ pot). The significant results were observed as data depicted that plants showed the maximum number of leaves (33.96) in pots those were supplemented with 150 mg/ pot phosphorous, similarly maximum leaf area was recorded (40.63 cm2). Furthermore, stalk length (26.09), plant fresh weight (9.16) and dry weight (3.05) was also maximum in pots supplemented with 150 mg/pots. In case of Potassium application, maximum number of leaves per plant (32.05) was observed and plants supplemented with 200 mg of potassium/pot. Combine application of P & K (150 mg + 200 mg) per plant showed best performance in parameters recorded in this study.
