Conclusion
This study showed that sulfur fertilizer application to Pangola grass pasture not only improved
CP and S concentration but also increased CP yield per area unit of 6-week old grass. Even though, Hub Kapong Soil Series was extremely poor in fertility and subsequently contributed to the low quality of grass,the result of this study showed that quality of grass can be improved through S fertilizer application at both rate of 12 and 24 kgS/rai. Sulfur application at
the rate of 24 kgS/rai provided the highest protein yield per area unit. There is a need for further study on the effect of S application on forage quality and itseffect on the favorability of this material to animal production
