Dr. Terry Bates emphasizes that accurate crop estimation provides valuable information, allowing growers to decide whether thinning is necessary. Thinning is often debated among growers, but knowing the crop load can significantly influence management decisions.  To simplify the estimation process, a crop estimation calculator has been developed. This tool allows growers to input row spacing, vine spacing, days after bloom, how many vines or length of row sampled, weight of fruit in sample, and estimated vine size for the sample.  With the information that you input, it calculates the harvest yield prediction.  It also factors in pruning weight to calculate the revised index, helping growers understand whether their crop load is balanced or overcropped, and then gives a Thinning Consideration in tons/acre (See Figure 1 below). The calculator aids in making informed decisions about thinning and ultimately helps maintain vine health and productivity.
