Abstract
A trial was conducted to find out the best treatment combination for an experiment “Effect of integrated manuring and growth regulators on vegetative growth and flowering of pineapple” with an objective to get high, uniform vegetative growth and flowering in pineapple by integrated application of manure and growth regulators. The result revealed that 75% of recommended NPK + 25% of N through organic recycling with vermicompost along with NAA@10ppm, GA3@50ppm Ethrel@25ppm Perform best treatment combination with respect to physiological characters like, number of leaves per plant (49.19) number of leaves produced (3.96 per plant per month), chlorophyll a content (0.385 mg/g fresh leaf), chlorophyll b content (0.160 mg/g fresh leaf) total chlorophyll content (0.552 mg/g fresh leaf), percentage of flowering (92.76 %), and maximum plant height (82.28cm), length of D- leaf (76.50cm), width of D-leaf (6.14cm), with, leaf area (273.17cm2). Flowering character like minimum number of days to flower initiation (42.84 days), minimum number of days required from flower initiation to fruit maturity (108.25 days) where significant variation found in 75% of recommended NPK + 25% of N through organic recycling with vermicompost along with NAA@10ppm.
