Study the Efficacy of Brassinolide and Triacontanol on Green and Seed Yield of Spinach –Beet (Beta vulgaris Var. bengalensis)

The present communication deals with the effect of growth regulators like Triacontanol and Brassinolide Research was conducted during the seasons of October 2009 to May 2010 to Study the efficacy of Brassinolide and Triacontanol ongreen and seed yield of Spinach– beet (Beta vulgaris var. bengalensis) at Horticultural Research Station, Mondouri, Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia, West Bengal. India. The aim of this research was to determine the influence of Brassinolide and Triacontanol to find out suitable concentration of these growth regulators on green yield, seed yield and quality aspects of spinach-beet. The experiment comprised of four different concentrations of each Brassinolide and Triacontanol along with water spray and no spray treatment applied in two varieties (viz., All Green and Punjab Selection) in three replication. It was recorded from this experiment that both Triacontonal and Brassinolide significantly influence on the growth and yield related attributes. For most of the yield related characters (like plant height, number of leaves per plant, fresh and dry weight, green yield, etc) were found effective with proportionately increased in the concentration of these chemicals from 0.5–1.5ppm with Triacontanol and 0.05– 0.2ppm with Brassinolide. Both these growth regulators though have promotive effect in flowering characters like basal girth of flower stalk, flower stalk length but they might have no effect on duration for flowering and seed maturity. Results showed that 1000 seed weight and seed yield were highest at Triacontanol @concentration of 0.5 ppm and Brassinolide @ of 0.05 ppm with All Green variety. Biochemical analysis revealed that carotene content, nitrogen percentage, protein content and ascorbic acid content were highly influenced by the application of Triacontanol and Brassinolide. It was observed that the lower concentration of Triacontanol and Brassinolide were found tobe more effective for carotene and ascorbic acid content The maximum Ascorbic acid content of (80.650mg/100g) was observed with 0.05ppm concentration of Brassinolide, Variety Punjab selection was found superior in relation to ascorbic acid and carotene content.
