Abstract

Effectiveness of urea fertilizer on the color gradation and growth density of peking grass. The research was conducted for three months. The research was experiment was used with a compete random pattern (RBD) with six treatments and four replications, so that there were 24 experimental units on each land measuring 1m 2. Urea fertilizer application namely P0 dose 0 g/m 2 , P1 dose 10 g/m 2 , P2 dose 20 g/m 2 , P3 dose 30 g/m 2 , P4 dose 40 g/m 2 and P5 dose 50 g/m 2. Application of urea fertilizer start at the beginning of planting. Variables observated were color gradations and the rate of growth of peking grass plants. Observation of color gradations was measured using leaf color chart, three months after planting. Observation of density is carried out using a grid (measuring tool for growing density of grass), five times per fifteen days after planting in each experimental plot. Data were analyzed using anova Fan Test and Duncan Multiple Range Tes (DMRT). The results of observation healthy peking grass leaf color are based on color chart measurement tools, green in color with a score of 3. Giving urea fertilizer at a dose of 20 g/m 2 and 30 g/m 2 is very effective in producing green color. The results of observing the growth rate of peking grass every fifteen days the most effective of 27.92 %, in the second fifteen day observation with treatment of urea fetilizer at a dose of 20 g/m 2 .
