Abstract
This experiment was carried out to investigate the growth responses of zoysiagrass (Zoysia japonica Steud.) as affected by prohexadione-calcium foliar application for the effective labour saving and cost down management in the lawn yard, field and golf course etc. The leaf growth of zoysiagrass treated with prohexadione-calcium one day after mowing was significantly slow compared to the untreated plot. And the effect was continued up to 50 days. The growth inhibition rate at the treated plot was 46 to 50% compared to untreated plot and the leaf widths treated with prohexadione-calcium were narrower than control plot. The change of leaf dry weight 10 days after prohexadione-calcium treated was significantly shown less speedy than untrated plot and the results were continued up to 40 days after application. The SPAD values of the leaf colour were increased in the treated plots and continued for 40 days more.
