• Yield table is a tabular a statement which summarizes per unit area basis all essential data relating to the development of a fully-stocked and regularly thinned even-aged crop at periodic intervals covering the greater part of its useful life.
• Yield tables are valuable in such forest management activities as regulating cut, determining rotation length, making growth estimates, and forest valuation.
• Yield tables are not applicable to uneven aged stands, since there is no one representative average age. A similar type of table has been produced for uneven-aged stands showing the volumes produced in growth for given periods with a certain level of growing stock on land of different site qualities.
• Yield records for uneven aged stands over long periods are required to prepare this kind of table.
• Yield Tables are a necessary forest management tool. They are used for predicting yields, as a standard for stocking, and as a measure of site quality.
• Yield predictions are used in analyses such as the financial analysis of proposed programs.
• It differs from the volume table in the sense that while anaverage tree by diaand/or ht classes, yield table gives differentparameters of crops,i.e. BA, Volume of standing crop, volume removed by thinning, MAI, CAI, etc
• In short it gives all the quantitative information regarding development of a crop.

Application of Yield Table

• Prediction of Yield
• Determination of site quality
• Estimation of G. S. at present or future
• Determination of increment of CAI and MAI
• Determination of rotation of maximum volume production: where CAI meets MAI
• Preparation of stock map by site quality
• Guide to silvicultural thinning

Limitations

• Mainly used for pure stand
• Age of stands needs to be known and so, not applicableto uneven-aged forest
• A lot of data necessary to develop yield tables
• Inflexible for change
• Give result only for certain specific condition

Kinds of Yield Table

There are several types of yield tables for even aged stands, depending on the independent variables used to predict growth.

1. Normal yield tables
2. Empirical yield tables
3. Variable density yield tables

Yield Tables are further classified as:

Based on grades of thinning

1. Single Yield Table
   • Parameters have been given only for one grade ofthinning which is usually C-grade
2. Multiple Yield Table
   • Table in which data are given for different grades of thinning

Based on volume/value given

1. Volume Yield Table
   • Yield Table which expresses outturn in terms of volumes
2. Money Yield Table
   • Yield Table in which outturn is expressed in terms ofmoney instead of volume
