Penambahan Bentonit dan Frekuensi Penyiraman untuk Peningkatan Kualitas Visual dan Fungsional Rumput Bermuda (Cynodon dactylon var evergreen).

Abstract

Golf courses are generally dominated by sand as growing media. As a result, high-permeability media so that watering becomes inefficient. This research was conducted to study the effect of the addition of bentonite and frequency of irrigation to improving visual and functional quality of bermuda grass (Cynodon dactylon var evergreen). Experiments using factorial completely randomized design with two treatment factors. The first factor is the addition of bentonite which consists of three levels ie 100% sand, 87.5% + 12.5% sand bentonite 25 mesh, and 75% sand + 25% bentonite 25 mesh. The second factor is the frequency of irrigation which consists of three levels ie every day, every two days, every three dayswith a volume of 400 ml / basin. This experiment uses three replications, so that there are 27 units experiment. Treatment of growing media mix with the irrigation frequency give significantly different results against all variables observation. Combination treatment media mix bentonite sand 75% + 25% with irrigation frequency of once every two days produce the best visual quality at the variable crown cover, shoot density and color of the leaves. Combination treatment media mix sand bentonite 87.5% + 12.5% with irrigation frequency of once every two days produce the best visual quality and functional at high variable grass, clipping dry weight, shoot dry weight, as well as on the efficiency of irrigation water use (EPAI). Combination treatment of a mixture of sand 75% + 25% bentonite with irrigation frequency of once every three days produce the best functional quality at the variable root dry weight and root length.
