Fertilizer divided becomes two, namely fertilizer organic and inorganic. According to USEPA, fertilizer organic is applied compost to plants as source nutrients. Fertilizer inorganic is fertilizer result of engineering process by chemical, physical and or biological and the results industry or factory maker fertilizer (Dewanto et al., 2013). Plant need fertilizer to reach production maximum. In research Roidah (2013) there is several of types of fertilizer the observed organic fertilizer cage contains 5 kg N, 3 kg P 2 O 5 and 5 kg K 2 O as well as other essential nutrients in relative amount small. This post aims to know the importance application fertilizer to growth plant cocoa. Based on some of the literature research described could be concluded that fertilizer inorganic and fertilizer organic have advantages as well as deficiencies in several parameters, namely content nutrients, duration nutrient availability, and cost. Application fertilizer inorganic takes to effect real to upgrade production plant cocoa faster and high but no sustainable whereas application fertilizer organic no take to effect real but sustainable. Then, the application of fertilizer on plants cocoa must be combined among fertilizer inorganic and fertilizer organic with composition certain. Application fertilizer inorganic and fertilizer organic in-unit tree plant cocoa need assessment more continue, study more carry on based on age, physiology, type soil, and method application. That thing is in tune with the condition geography in Indonesia which is an archipelagic country so every area has different traits.

This study aims to determine the pattern of agarwood marketing channels, and analyze the marketing efficiency of agarwood in CV. Cahaya Gaharu Village Dendang Kec. Stabat. The type of research used is descriptive and qualitative. Determination of the research location is done intentionally or purposively. The analysis technique used is to determine the pattern of marketing channels and calculate marketing margins. The marketing process carried out by CV. Cahaya Gaharu creates a marketing channel, namely CV. Cahaya Gaharu by coming to the farmer's place and buying it according to a predetermined price, then CV. Cahaya Gaharu sells it or markets it domestically or abroad. The marketing margin obtained from the only marketing channel is Rp. 6,980,000 per kilogram of wood, the share margin received is very small, namely 0.29%. This is because farmers sell directly to retailers who sell agricultural products in the country and abroad. Efficiency in the marketing channel of 40% indicates that the marketing channel is less efficient. The lack of efficiency from this business process is due to the many challenges faced, such as transportation costs and harvesting agarwood which takes a long life of up to 7 years, there is uncertainty in harvesting agarwood which can worsen supply.
