This study aimed to found out the effect of treatment combination toward plant height, number of leaf, leaf area, and total dry weight. This study was done by using Split Plot Design consist of 2 factors repeated thrice for each treatment combination. Main plot are potatoes (V) used from Germany variety (V1) and Flowered Granola variety (V2) and sub plot is mulch application (M) consist of 5 applications which are control (no mulch) (M0), paddy straw application (M1), Mexican sunflower application (M2), silver and black plastic mulch application (MPHP) (M3), black plastic mulch application (M4). Observed parameters were plant height, number of leaf, leaf area and total dry weight at 4 week after planting, 6 week after planting, 8 week after planting and 10 week after planting. Analysis result showed that treatment combination for varieties and mulch application at 4 and 6 week after planting has effect toward plant height (p<0,05) while at 8 and 10 week after planting did not affect plant height. Treatment combination for varieties and mulch application at 4, 6 and 8 week after planting has effect toward number of leaf (p<0,05) while at 10 week after planting did not affect number of leaf. Treatment combination for varieties and mulch application at 4, 6, 8 and 10 week after planting has effect toward leaf area (p<0,05). Treatment combination for varieties and mulch application at 4, 6, 8 and 10 week after planting has effect toward total dry weight (p<0,05).
