A way was proposed, which determined applicable dose of nitrogen fertilizer in the first and second half of growth, when the number of grains per ear and 1000 grain weight were planned, in advance, by the mixing regressive model. The relative differances between actual yield by the planned yielding quantity and account value of the applicable dose of nitrogen fertilizer in first and second half of growth were 4.69 percent in Kosan and 4.44 percent in Wonsan.
