Abstract :

The hectarage of rubber has decreased year by year. Thus, future planting has been pushed to the problem soils which are problematic areas especially hilly areas. According to this issue, the government through Malaysian Rubber Board (MRB) decided to address this problem by implementing the MRB Strategies 2010-2020. There are five strategies; to increase planting area by 40,000 hectares per year, to expand rubber area by new planting 20,000 hectares per year, to accelerate replanting by high yielding clones, promote the mechanization and automation and enhance adoption in the latest technology in latex harvesting. This study is related to strategy number two which is to expand rubber area with new planting 20,000 hectares per year. The objective of this experiment is to study the effect of different technique of fertilizer application on the growth rate of rubber trees planted in hilly area. In this study, highly productive rubber clone, PB350 treated with two different of fertilizer application which is deep placing and broadcast application. In terms of the girth increment, there were significant difference between treatments and deep placing showed better performance compared to broadcast. As conclusion, it was shown that applying the correct and suitable fertilizer application especially in hilly areas which gave the higher girth increment of 13.23 cm/year compared to the broadcast application (11.91 cm/year). From this study, it can be suggested that for hilly area, deep placing of fertilizer application should be applied in order to obtain the higher girth increment (cm/year). KEYWORDS Fertilizer, Deep
