IMPACT OF DIFFERENT ORGANIC LEACHATE AND CLYBIO CONCENTRATIONS ON GROWTH AND YIELD OF ORNAMENTAL SUNFLOWER

Abstract

A field experiment was accomplished at the horticulture farm of Sher-e-Bangla Agricultural University, Dhaka, during the period from October 2021 to December 2021 to evaluate the impact of different organic leachate and clybio concentrations on growth and yield of ornamental sunflowers. Organic leachates, viz. T = Control (No leachate application), V = Vermicompost leachate, N = Neem oil cake leachate, and M = Mustard oil cake leachate, and Clybio concentrations, viz. C 1 = No clybio application (Control), C 2 = Clybio 4 ml/L water and C 3 = Clybio 6 ml/L, were used in this experiment arranged in a Randomized Complete Block Design (RCBD) with three replications. Data on different growth, flower yield and quality attribute parameters were taken, and all the treatments showed significant variations. Maximum stalk diameter (7.1 mm), ray floret area (6.3 cm 2 ), flower head size (15.0 cm), flower head weight (30.4 g), number of secondary flowers per plant in the cut-head (13.3) and the vase life of half-blooming stage (7 days) were found in organic leachates (N), whereas minimum in (T) and among different clybio concentrations, maximum stalk diameter (6.6 mm), ray floret area (6.0 cm 2 ), flower head size (14.3 cm), flower head weight (28.1 g), number of secondary flowers per plant in cut-head (14.3) were found from (C 3 ) whereas minimum in (C 1 ). In terms of combination effects, (NC 3 ) showed the superiority of all parameters, whereas the minimum was found in (TC 1 ). In view of overall performances, the neem oil cake leachate with higher clybio concentrations has the potential for quality sunflower production.
