    INFLUENCE OF THIOUREA CONCENTRATIONS AND APPLICATION FREQUENCY ON GROWTH AND YIELD OF LIGHT PINK LISIANTHUS
    (DEPARTMENT OF HORTICULTURE, 2020) MALIHA, MAISHA
    An experiment was accomplished in the Horticulture farm Sher-e-Bangla Agricultural University, Dhaka during the period from November 2018- May 2019 to study the influence of thiourea concentrations and application frequency on growth and yield of light pink lisianthus (Eustoma grandiflorum). Thiourea concentrations viz., C 1 : 500 ppm, C 2 :1000 ppm, C 3 :1500 ppm and application frequency, T 0 : Control: No thiourea application, T 1 II : single application, T 2 : twice application were used in this experiment arranged in a Randomized Complete Block Design with three replications. Data on growth, physiology, yield and quality attributes parameters were taken in which all the treatments showed significant variations. Among thiourea concentrations, maximum plant height (59.6 cm), stem number/plant (4.4), flower/plant (26.6), maximum chlorophyll content (56.6), flower head diameter (6.3 cm), yield/plot (793.2) were recorded from C 3 and for application frequency, the longest Stem (47.3 cm), peduncle length (12.7 cm), maximum stem diameter (4.3 mm), flower per plot (898.3) in twice application (T 2 ). Furthermore maximum flower yield per plant (37.3) and yield per plot (1116.7) were found in C 3 T 2 and minimum yield per plant (10.3), yield per plot (309.7) in C 0 T 0 . In view of overall observations, twice application of thiourea at 1500 ppm concentrations had showed the best result and would be the potential for increasing the lisianthus flower production.
