The purpose of this study was to determine the effect of the timeof manure on the vegetative growth of MDH guava. This research wasconducted in the green house in March to August 2018. This study useda randomized block design with 9 repetitions and 3 treatments, namely:(1) fertilization at the beginning of planting, (2) fertilization in the 1stand 3rd month after planting, and (3) fertilization in the 1st and 5thmonths after planting. Data were analyzed using ANOVA test. Theresults of this study indicate that manure has a significant effect on thenumber of leaf parameters, but does not significantly affect plantheight, number of primary branches, and number of secondarybranches.
