FERTILIZING AMOUNT SETTING METHOD, FERTILIZING AMOUNT SETTING DEVICE, AND FERTILIZING AMOUNT SETTING PROGRAM

摘要

This fertilizing amount setting device is capable of setting the fertilizing amount allowing realization of high yields and excellent taste in grain cultivation. This fertilizing amount setting device (5) is provided with a fertilizing amount setting unit (50) which sets the fertilizing amount, which relates to grain yield and grain taste, on the basis of a target taste value for grain taste and a target yield for the grain yield. The fertilizing amount setting unit (50) is provided with a yield difference calculation unit (51) which calculates the yield difference, which is the difference between the target yield and the actual yield performance of the grain, and a taste difference calculation unit (52) which calculates the taste difference, which is the difference between the target taste and the actual taste performance of the grain. The fertilizing amount is set on the basis of the calculated yield difference and the calculated taste difference.
