This research was conducted to study about effect of irrigation volume and fertilization frequency on Pak Choi (Brassica rapa gp. Chinensis) growth and production with sandphonics. The experiment was arranged in randomized completely block design, consisting of two factors with three replications. The first factor was irrigation volume consisted on four levels: I1(1xEo), I2(2xEo), I3(3xEo), I4(4xEo). The second factor was fertilization frequency consisted of four levels: F1: every 4 day, F2: every 6 day, F3: every 8 day, F4: every 12 day, with the same concentrate in every treatment is 1.5 g hidroponic fertilizer/l. Irrigation volume cause plant high is 3 Eo and 4 Eo, total of fresh wight on each pot is 2 Eo, and total of dry root weight is 4 Eo. Fertilization frequency cause the highest leaf number for the ages of plant is 4 weeks after planting, the average of leaf width, total of fresh weight, and total of dry weight is 4 day. The highest production resulted by irrigation volume treatment in the amount of 2 Eo and fertilization frequency in every 6 day.
