Effect of Growth Restraint of White Clover (Trifolium repens) as Affected by Prohexadione-calcium Application

This experiment was carried out to investigate the growth responses of white clover (Trifolium repens L.) as affected by prohexadione-calcium foliar application for the growth restraint in the lawn yard, field and golf course etc. The leaf length and leaf weight of white clover were significantly retarded compared to the untreated plot with foliar application of prohexadione-calcium after mowing within 1 day, and the effect was continued up to 50 days. The leaf area of clover with prohexadione-calcium treatment was to be narrowed as compared to untreated plot. The SPAD value of the leaf colour was increased in the treated plots and was to be continued for 40 days more. The coverage rate of clover was decreased with prohexadione-calcium foliar application after mowing in the lawn ground.
