Abstract
本試驗係以三種氮鉀施肥法及二種不同之株型稻，作田間試驗，以探討其對稻穀之產量及對農藝性狀之影響。經一年二期作試驗及詳細調查各性狀後，結果摘要如下：
1．不同施肥法對矮脚尖之分蘗數之影響較農育61號爲大，肥料分施可促進矮腳尖之分蘗，V字型法則降低其分蘗數。農育61號則頗爲穩定，受不同施肥法之影響少，第二期作之分蘗數均比第一期作爲少。
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.
