The Effects of Paclobutrazol Application at Different Growth Stages and Concentrations Rates on Growth, Tuber Yield and Starch Quality of Cassava Grown under Rainfed Conditions

Authors:Davenport Desharious, Reese Troylen

Abstract


The purpose of this study was to investigate the effects of cassava (Manihot esculenta Crant) application at different growth stages and concentrations on cassava growth, tuber yield and starch quality under rainfed conditions. The factorial in RCBD (Randomized Complete Block Design) with four replicates was used in this experiment. The first factor included the use of PBZ in three growth stages, 90, 150 and 210 DAP. The results showed that the application of PBZ on cassava plants significantly inhibited the plant height and tended to reduce the LAI of cassava at 280 DAP. In this experiment, plants that applied PBZ at 90 DAP were shorter than PBZ plants that were applied at 150, 210 DAP and at harvest (280 DAP).
