Plant growth and flowering in rose as influenced by application of calcium sulphate and salicylic acid

Abstract

The experiment was carried out at Horticulture Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi during 2018-19. The experiment was laid out in a Randomized Block Design (RBD) with four replications and seven treatments comprising of three levels each of CaSO4 (5, 10 and 15 ppm) and SA (50, 100 and 150 ppm) along with control (Distilled water) in protected condition. Among all treatments, application of salicylic acid (SA) 150 ppm was most effective treatment for increasing growth parameters such as plant height, number of leaves per plant or per branch, number of branches per plant, flowering characters viz., early bud initiation, flower initiation, petals length, petal breadth and in all others parameters. From economic point of view, SA 150 ppm was found beneficial as compared to rest of the treatments.
