The assessment aimed to study the effects of nitrogen, phosphorus, potassium/NPK and zeolite on the growth and yield of irrigated rice. Field experiments were carried out at farmer field of Ikur Koto, Padang, West Sumatra, during dry and wet season of 1999-2000. Seven treatments were arranged in a randomized complete block design with four replications. Results showed that no significant effect of NPK and zeolite on the growth and yield of irrigated rice, except numbers of panicle and 1000 grains weight. However, the highest yield (5,95 t/ha) obtained in dry season 1999 by application of 200 kg urea + 100 kg SP-36 + 200 kg zeolite per hectare, and in wet season 1999/2000 (7.0 t/ha) by application of 150 kg urea + 100 kg SP-36 + 200 kg zeolite per hectare.
