Abstract

The objective of the study is to investigate the effect of the mixture of sow dust, zeolit, and sand as media on turf qualities of Bermuda Grass (Cynodon dactylon var. Tiffdwarf). There are 6 treatments of planting media including : sand 100%, sand 75 % + saw dust 25 % + zeolit 0 %, sand 50 % + sow dust 50 % + zeolit 0 %, sand 50 % + sow dust 25 % + zeolit 25 %, and sand 50 % + sow dust 0 % + zeolit 50 %. The treatment have 3 replication ang arranged in Randomized Block Design. Analysis of media show the addition of sow dust 25 - 50 % into sand media increased physical qualities of media including the  increasing of the water content of media and decreased bulk density of the media. The addition of sow dust 25 % into sand media perform the best qualities of turf compared to the other media including of dry weight of shoots, density of shoot, height of shoot, length of root and the shoot - root ratio.

Abstract

The objectives of this study is to investigate the effect of (Urea) and Polymer Coated Urea (Slow Release N - Fertilizer) on the growth and quality of turf Bermuda grass (Cynodon dactylon var. Tifdwarf.) and to find the optimum rate. Treatments are urea and PCU rate at 4.5 g, 9.0g and 13.5 g N/m2/application, respectively. The experiment was arranged in Randomized Block design with 3 replications. Fertilizers were applied 6 times in every 2 locals. The result showed that in the end of the experiment, the higher values of grass height. number of shoots resiliance. Fresh and dry weight were obtained with PCU /3.5 g N/m2/application. The highest dosage of PCU resulted d the highest quality of turf grass.   Key words: Urea, Polymer Coated urea, Bermuda grass
