Effect of plant growth enhancers on growth and flowering of tuberose cv. Prajwal

Abstract

The experiment on “Effect of plant growth enhancers on growth and flowering of tuberose cv. Prajwal” comprised of 13 treatments of three concentrations of each plant growth enhancers i.e. enriched sap of banana pseudostem (5000 ppm, 10,000 ppm and 15,000 ppm), brassinosteroid (0.25 ppm, 0.50 ppm and 0.75 ppm), each GA3 and BA (50 ppm, 100 ppm and 150 ppm, respectively). The results indicate that the growth parameters were significantly differed with various treatments. Among different concentrations of plant growth enhancers, T4 (Enriched sap of banana pseudostem at 15,000 ppm) was found significantly highest plant height (74.8 cm), number of leaves (70.20) and leaf area (65.20 cm2). An advanced rachis emergence (37.53 days) and first florets opening (7 days), significantly higher spike length (103 cm), rachis length (27.2 cm) and vase life (11.20 days) were also recorded with the application of 15,000 ppm Enriched sap of banana pseudostem.
