The aim of this research was to learn about the vegetative growth level of some varieties of pine-apple in intercropping with sweet potato,  to obtain suitable pineapple varieties which can be used in intercropping with sweet potato, and to obtain the suitable proportion of pineapple in intercropping with sweet potato. This research was conducted from November 2007 until March 2008 in Jumantono, Karanganyar and the Laboratory of  Ecology and Management of Plant Production, Agriculture Faculty, Sebelas Maret University. The research was arranged with Randomized Completely Block Design  factorial with two treat-ment factor. The first factor was pineapple variety consisted of cayenne and queen variety. The second factor was proportion of intercropping consisted of 0%,  25%, 50% and 75% proportion of sweet potato. Additional treatment was sweet potato monoculture.  Each treatment was repeated 3 times. The data were analyzed with normality test and continued by analysis of varian based on F test and contrast orthogonal. For comparable test done with DMRT on 5% level. Variable of this research was height of plant, number of leaf, canopy wide, dry weight of plant, leaf area, leaf area index, relative growth rate, net asimilation rate, and leaf area index.The results showed that the growth of pineapple monoculture was better than intercropping with sweet potato,  intercropping proportion with give the best pineapple vegetative growth is 25 % proportion of sweet potato, and the vegetative growth of cayenne was better than queen variety.
