Abstract
Objective of the research was to study the effect of space arrangement on competitive ratio, yield component and yield of intercropping sweet corn and peanut. The research was carried out at Sukasirnarasa village, Rancakalong sub-district, Sumedang district with the altitude is 900 m above sea level. Research methods was experimental with six treatments. Space arrangement as treatments of the experiment were 25/2; 25/3; 20/2; 20/3; 15/3 and 15/4. Plant distance of sweet corn was 75 cm inter-rows and 25 cm intra-rows. While peanut was planted between rows of sweet corn with space arrange corresponding treatments. The experiment was used simple Randomized Block Design and the treatment was repeated four times. Result of the experiment showed that space arrangement affected plant height and diameter of cob of sweet corn; pods number/plant, seed size and weight per plot of peanut. Space arrangement 20/3 gave yield component more, but competitive ratio between sweet corn and peanut relatively balance at 20/3 space arrange.
