Effect of nitrogen, phosphorus and potassium on growth and flowering of Barleria cristata Linn.

Abstract

A field study was conducted to investigate the response of Barleria cristata Linn. to various levels of nitrogen, phosphorus and potassium, i.e. 0, 15, 30 g/ m2. Vegetative characters like plant height, plant spread, number of primary branches, secondary branches and number of leaves per plant were recorded maximum at 30 g/ m2 each of N, P and K and flowering characters like earlier bud formation, flowering, number of flowers per cluster, flower clusters per plant, and duration of flowering was recorded maximum at 15 g/ m2 of N and 30 g/ m2 each of P and K.
