Physical and economic optima in sowing densities of spring barley in Scotland.

Abstract

In general, studies on the patterns of innovation in industry and agriculture have described innovations that have already occurred (McCarthy, 1971). Although these studies are useful in describing the characteristics of innovations, they have not, themselves, formed part of the adoption process of any innovation. The analysis contained in this thesis involves the collection of evidence that would assist in the adoption process of a simple innovation in agriculture. The innovation proposed is the reduction in sowing densities for spring barley, which could lead to savings in costs. The evidence is both technical and economic and the arguments are set against the background of barley production and marketing, both of seed and grain, with particular reference to Scotland. Projections are made into the likely effects of some developments in the industry and the crop, and the possible future savings from density reductions are calculated. The analysis is intended not only to provide information on a specific agricultural problem but to illustrate an approach to agricultural management involving both technical and economic appraisals.
