The purpose of this calculator is to provide a grower with the means to estimate the crop on the trees and further real-time reevaluation throughout the season. Updating the inputted data will help validate the projections made early in the season, and help build confidence in the estimating capability of the estimator. This information could also serve as the input channel for an industry-wide database to estimate the crop volume.
The calculator is an input screen with the option of using English or Metric units. Data detailing one or more blocks are inputted and production estimates are entered and summarized by variety for the entire orchard.
A block is a unit area. It could be the entire grove or any part of the grove that the grower identifies as unique. The block is identified by a block number provided by the calculator which could be renamed. Blocks could be added, removed or recalled for review and editing. A block may contain only a single variety, which the user can select from the variety pull down menu.
It is advisable to input the block size in acres/hectares. It is useful to track the production per acre/hectare in the particular block. It is also useful in calculating the number of trees per acre/hectare and per block by filling the tree spacing information.
If the tree count for the block is known, then the tree spacing portion could be skipped and only the total tree count will suffice.
If significant numbers of pollinizer trees are within the block, better accuracy is achieved by removing the pollinizer trees from the calculation of the production of the dominant variety of the block.
There are two input options for pollinizers:
1. The number of pollinizer trees per acre/hectare
2. The percent of pollinizer trees per acre/hectare.
The calculator is designed to accept input from any one of 4 estimating methods:
The cumulative total for all the blocks of each variety is presented in the variety summary section.
