Effect of Plant Growth Regulators on Growth & Flowering of Seed Guar Cultivars

The seed cluster bean exhibited significant variations in growth and flowering due to spray of growth regulators. The highest plant height was recorded in the HG 365 and among the growth regulators maximum plant height was recorded by the application of triacontanol at 1500 ppm which was on par with 1000 ppm. In case of earliest occurrence of 50% flowering was noticed in variety HG 563 and lowest number of days to 50% flowering was recorded by the application of CCC at 1500 ppm which was on par with CCC 1000 ppm. The highest seed yield per plant was recorded by HG 365, whereas in growth regulators maximum seed yield per plant was recorded by the application of CCC at 1500 ppm which was on par with CCC 1000 ppm.
