The comparative study on the effect of urea and slow release nitrogen fertilizer (SRNF) rates on yield and yield components of hybrid maize Pacific 999 varieties planted in Kamphaeng Saen soil series. The experiment was done 2 crops in a Randomized Complete Block Design (RCBD) with 3 replications and consisting of 9 treatments. The results revealed that the SRNF application at a rate of 60 kg/rai gave the highest ear weight, ear without husk weight, grain weight, 1,000 grain weight, total N and protein in grain of maize which were not different from the chemical fertilizer application based on soil chemical analysis using SRNF at a rate of 50 kg/rai, and the urea application at a rate of 52.17 kg/rai
