Careful grading is imperative for discriminating markets. Uniformity in size, shape, color, markings and ripeness count for more than most growers realize. Eighty bushels of tomatoes properly graded will bring more money on most markets than 100 bushels ungraded. One inferior specimen may repel a dozen buyers.

The number of grades necessarily varies with the market and the vegetable to be graded. It is generally profitable to make at least three market grades, according to size or other points of merit. The work of grading should be most carefully supervised in order that the grades established be maintained. Badly damaged and very imperfect specimens should be discarded.
