Title : The Effect of Plant Spacing and ZA Fertilizer to Availability and Uptake of N, S with Groundnut  (Arachis Hypogaea L.) Indicator on Alfisols. The aim of this research is to know the effect of ZA fertilizer and plant spacing to the availability and uptake of Nitrogen and Sulfur. This research have been done at Jumantono field, Sukosari, Jumantono, Karanganyar, started from December 2006 until January 2007. This research used factorial experiment that arranged in Randomized Complete Block Design (RCBD) with two experimental factors. The first factor was 4 levels of ZA fertilizer dosage i.e : 0 kg/ha (Z0), 50 kg/ha (Z1), 100 kg/ha (Z2) and 150 kg/ha (Z3). And second factor was 3 levels of plant spacing i.e : 20 x 20 cm (J1), 30 x15 cm (J3) and 25 x 20 cm (J3). Observation variables include soil variable ( N of soil, available S and pH H2O) and plant variable (N uptake, S uptake, and weight of dry straw). Data analysis used F test, Kruskal-Wallis test, Duncan’s Multiple Range (DMR) test at 5% in level, Mood Median test and Correlation test.Result of this research shows that ZA fertilizer and plant spacing can increase the available sulfur on soil and uptake of N. The highest available S neach 100 kg ZA/ha and 30 x 15 cm plant spacing (0,0277me/100 g),.and the highest average of N uptake is on without ZA and 30 x 15 cm plant spacing (0,623g). ZA fertilizer added and plant spacing has no significantly effect to  available N, S uptake, weight of dry straw and pH H2O.
