The study was conducted at. 60 farmers were randomly selected from three villages of Unsum, Lenggang and Puri, Dusun Tengah District. Samples of marketing agencies were selected based on non probability sampling method. Data analyses were analysis of profit function, and analysis of marketing, as well as descriptive analysis on market structure, performance and conduct to qualitatively measure marketing efficiency. Results of the study showed that there we two marketing channels in the study area, i.e. channel 1: Farmer –trader 1 –trader II (distributor) – rubber processing factory, and channel 2: Farmer –trader II (distributor)- rubber processing factory. Analysis of marketing margin indicated that price share received by farmers was 67,35%, whereas that received by trader I was 79,59%, and that received by trader II (distributor) was 100%.

Abstract

The research that was aimed to create a new variation on sweet potato population was conducted at 2003 and 2004. Crossing between two introduction clones (Beniazuma and BIS-214) as a parent of bearing tuber-protein content genes with five clones of tuber high yield potential, was obtained 1157 genotypes of new hybrid F1. The selection result found 168 new clones having minimum yield as 0.5 kg/plant or  20 ton/ha and 3% tuber protein content on dry weight basis. Among 168 clones there were 21 genotypes with protein yield range from 1.0-2.5 ton protein content/ha
