Obtaining Proportion of Optimum Yield when Full Yield is unattainable

Abstract

In a situation where it is not feasible to obtain full yield at harvest time because it is unattainable or simply unavoidable; combined methods of calculus of variation and maximum likelihood estimates are used to obtain a proportion of this yield. This is obtained for both known (desired) and unknown (estimable) proportions of the maximum yield on rectangular and square plot – formations. The reference model is that due to Berry (1967) on intra-row and inter-row spacing experiment.
Keywords: Berry's model, Calculus of variations, Maximum likelihood, Plot-formations.
