GENERALIZED CROP - FERTILIZER PRODUCTION FUNCTION

The problem examined in this study is the derivation of a generalized crop-fertilizer production function describing the response relation between measured soil characteristics, applied nutrients, weather and crop yield.

RYAN, JAMES G. · 1970

Abstract

It is hypothesized the function can be used to generate specific fertilizer recommendations to farmers based on soil analysis. The data come from potato-fertilizer experiments conducted on 65 farm locations over a seven-year period in the Sierra Region of Peru. A quadratic model was chosen as the most appropriate form to describe the response relationships in these data.
