The objectives of this experiment were to find out the effects of different methods of NK-fertilization on the agronomic characters and yield of rice. This experiment consisted of three methods of NK-fertilization (Matsushima's V-shape method, Split application, arid Conventional method) and two rice varieties (Ai-chueh-chien, and Tainung yu 61). A split plot design was used in the trial with the methods of NK-fertilization as the main plots and the variety as the sub-plots in two replications. Five seedlings per hill were transplanted at a spacing of 25×20cm^2. The rate of N, P2O5, and K2O added in each treatment for whole growth season was 100, 40 and 40 kg/ha, respectively. The plant height, no. of tillers, leaf area index (LAI) and dry matter were all measured at the stages of tillering, panicle differentiation, heading, and harvest. After harvest, length of internodes, no. of panicles per hill, length and weight of panda, no. of spikelets per panicle, percentage of filled grains, weight of 1,000 kernels, and grain yield were al investigated.
