In this report, the practicability of the non-destructive growth measurement model for the cabbage plug seedlings population developed in a previous report was evaluated. The evaluation plug seedlings population consisted of various planting patterns caused by missing plants. The soil coverage and standard deviation of lightness of the plug seedlings population with missing plants varied with the increases in the total leaf area, similarly to the plug seedlings population without missing plants. The predicted total leaf area of the evaluation plug seedlings population fitted well with the measured values. The coefficient of determination (R2) was 0.937. The developed model could predict the total leaf area of the plug seedlings populations with various planting patterns. The practicability of the non-destructive growth measurement model was confirmed.
