From the table it is seen that the Coefficient of determination. The parameters of the oil content of the crop in the year 2556 and the year 2557 is different from the value of the MC and DM can be seen that there is no precision is the Coefficient of determination are 0.70 and 0.42 respectively, and on the same charges. Root mean square of the prediction of the parameters of the oil content to the maximum error. Which is equal to 6.00, 5.01.
