INFLUENCE OF THIOUREA CONCENTRATIONS ON GROWTH AND YIELD OF LIGHT PINK LISIANTHUS

An experiment was accomplished in the Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka, during the period from November 2018 to May 2019 to study the influence of thiourea at different concentration levels on the growth and yield of light pink lisianthus (Eustoma grandiflorum). Thiourea concentrations, viz., C₁: 500 ppm, C₂: 1000 ppm, and C₃: 1500 ppm was used in this experiment, arranged in a randomized complete block design with three replications. Data on growth, physiology, yield, and quality attribute parameters were taken, and all the treatments showed significant variations. Among thiourea concentrations, C₃ treatment produced tallest plant (59.6 cm), maximum stem number/plant (4.4), flower/plant (26.6), the highest SPAD value (56.6), the largest flower head diameter (6.3 cm), and the yield/plot (793.2). Overall, thiourea at 1500 ppm concentrations produced the best result and the greatest potential for increasing the Lisianthus flower production.
