See Fig. 1). In view of the method used for calculating the optimum harvest fraction. it is obvious that the degree of accuracy of the estimate of the optimum harvest fraction should increase with the similarity of environmental conditions during the two successive intervals involved. 1 g m- 2 • respectively. because the weather was fairly stable during the experiment. The results presented should be regarded as a first approximation to the optimum harvesting under field conditions. The method can be improved in many ways.
