Ketahanan rumput golf (Cynodon dactylon var. Tift dwarft 419) pada kondisi salinitas yang berbeda dengan penambahan asam humat

Abstract

The objectives of this research was study the effects of salinity and humic acid on growth, production and quality of Cynodon dactylon. The experimental units were arranged in a completely randomized factorial design 2x5 with 3 replications using Cynodon dactylon as host plant. The first factor was huinic acid, consisting of HO (without humic acid) and Hl(with humic acid) and the second factor was the level of salinity consisting of SO (0 ppm); S1 (2500 ppm); S2 (5000 ppm); S3 (7500 ppm); S4 (10000 pprn). Analyses of Variance, Duncan Multiple Range Tests were used to analyze and assist in interpretation of the data. Result showed that salinity very significantly different (P<0.01) on color of leaf, percentage death, vertical high plant and biomass dry weight. Humic acid significantly different (P<O.OOj) on vertical high plant. Humic acid didn't significantly different on color of leaf, density, total an individual, percentage of death, biomass dry weight and root dry weight. Salinity didn't significantly different on density, total an individual and root dry weight.
