The aim of this study is to investigate response of potato crop to drip irrigation application with different interval and volume application, due to the effect of that application to potato growth and yield. The research was conducted at Sapikerep, District of Sukapura, Probolinggo, ± 1700 m above sea level, with soil type Andosol, from May until August 2007. The experiment was arranged in a factorial block random design with 2 factor, comprised : Factor I (Interval of giving water) are I1 (Interval of giving water once at 2 day), I2 (Interval of giving water once at 3 day), I3 (Interval of giving water once at 4 day), and Factor II (Volume of giving water) are V1 (Volume application of giving water at 50 ml), V2 (Volume application of giving water at 100 ml), V3 (Volume application of giving water at 150 ml). Arranged as much 9 treatment combination, and repeated 3 times with 3 plants models The observation started at 47 daps on a 7-day interval. As for the variable comprised 2 types, the first is non-destructive observation, consist of: plants height (cm), number of leaves, and leaf area(cm2), and the second is destructive observation, consist of : number of tuber per plant, tuber weight per plant (g), tuber weight per tuber (g), and total yield (t/ha). Pursuant to Anova, showed real interaction between interval and volume of giving water to all variable and age of observation. Separately, either interval or volume of giving water, shows reable influence to all variable and age of observation. Based on average test at each variable, the combination of I1V1 in giving water twice per day with volume 50 ml shows the best result on growth of variable. It suggested that availability of giving water with during interval 2 days is enable dampness of land; ground can awake, so that grow on crop can exploit water maximally compared to giving of water with interval 3 and 4 days once where water represent very important constrictor factor in growth of plant. It is different with I1V2 (the interval of giving water once per two day and the volume is 100ml) and I1V3 (the interval of giving water once per two day and the volume is 150ml) where all the variables is less than I1V1. It is because the soil near the root is too damp so much water will endanger the plan’s root, caused by the lack of air at the soil (Noorhadi dan sudadi, 2003). If the root system is a place where water is in so the plant influence the speed of the plan’s growth. Based on the analysis for all the variables result are got which are the highest is I2V2 (the interval of giving water once per three day and the volume is 100ml). It is different with the growth where the highest is I1V1 (the interval of giving water once per two day and the volume is 50ml). It might be on the I1V1 photosintat which is produced leaf used for the vegetative growth only so over photosintat which is saved is so little. The I2V2 can take water eficiently for the fisiological process and the metabolism of the plant, so water which is taken can be used maximally for photosynthesis. In the limited water can stimulate the plant to speed vegetative phase to generative phase, so the result from photosyntesis not only for the plant’s growth itself but also is kept as substitution food so in I2V2 is got that the growth result is not too maximal but the result of the harvest is higher than others.
