The objective of this study was to compare the increasing protein level of fresh and dry coconut meal by urea-yeast (Saccharomyces cerevisiae) fermentation process. The design was 2 X 8 factorial in CRD : factor A composed of 2 factors (dry and fresh coconut meal) and factor B composed of 8 factors (day of fermentation: 5, 10, 15, 20, 25, 30, 35 and 40 days). The samples of each day of fermentation were collected for crude protein analysis. The data was analyzed by using Analysis of Variance (ANOVA). The results were shown that the protein level at the different days of fermentation was different in fresh and dry coconut meal (P<0.05) which protein level of fresh coconut meal at day 10 was highest (34.40 %). While protein level in dry coconut meal was...

Methane is one of important greenhouse gases emitted from submerged paddy soil under anaerobic condition. The objective of the present experiment was to study the influence of sulfate and urea on methane production in paddy soil. Four rates of sulfate (0, 50, 100 and 210 kg SO42- ha-1) were set up by using ammonium phosphate (16-20-0, 42 % sulfate) with the amount of N, P2O5 and K2O for each treatment being balanced by using urea, rock phosphate and potassium chloride. In addition, soil without urea application was prepared. All soils were incubated in bottles for 21 days in oxygen-free nitrogen ambient. Result showed that there is a linear relationship with negative correlation between methane production in soil and sulfate contents. The soil without urea...
