An on-farm experiment was carried out at the paddy fields located in Ohnishi, Sakurai, Nara Japan In Ohnishi, the unit area of the paddy fields that are cooperatively managed by farmers is about 38 ha, and about 380 paddy fields. The cropping system of these fields has been three cropping in two years.1.The multivariate analysis clearly demonstrated the high contribution of the agronomic factors (soil fertility factor, early growth factor, N dressing and uptake factor) as yield-limiting component factors. The agronomic factors (soil fertility factor, early growth factor, N dressing and uptake factor) could control about 77.1% of the spatially structured variation of the brown rice yield.2.The uniformity of the cropping system, the cultivation method and the land utilization among fields influenced spatial dependences. Maps of Npf, which were generated by interpolation among estimated values by block kriging, will be made available to the farmer to apply top-dressing at optimal rates depending on the plant condition.3.The proper management of variable rate seeding in proportion to the soil moisture percentage on dried soil basis at seeding in the wheat field may be able to control the number of panicles in the field to bring the adequate average wheat yield. This variable rate management may control 42.7% of the controllable proportion to total variation of wheat yield in the field.

在日本奈良樱井大西的稻田进行了田间试验。大西的农民合作经营稻田的单位面积约为38公顷，稻田约380块。这些地的种植制度是两年三熟。多因素分析表明，农艺因子（土壤肥力因子、早期生长因子、氮肥和吸收因子）作为产量限制因子的贡献较大。农艺因子（土壤肥力因子、早期生长因子、氮肥和吸收因子）对糙米产量空间结构变化的控制作用约为77.1%。农田间种植制度、耕作方式和土地利用的均匀性影响着空间依赖性。将向农民提供Npf地图，这些地图是通过块克里格法的估计值插值生成的，以根据植物条件以最佳速率施用追肥。在小麦田间播种时，按干土土壤水分比例进行适当的变率播种管理，可以控制田间穗数，使小麦获得足够的平均产量。采用可变率管理，可控制田间小麦产量变化总量的42.7%。
