Method for determination of planting and harvesting dates by fuzzy regression

Alexander Sadovski

Abstract: In this paper we investigate planting and harvesting dates of maize, potatoes and sugarbeets grown on the territory of selected USA states, which have similar homoclimates with Bulgaria. Such data are very important in agricultural practice and particularly in scheduling irrigation of agricultural crops. Fuzzy set theory provides a strict mathematical framework in which vague conceptual phenomena can be precisely studied and described. A simple solution approach was applied to solve a general fuzzy system of linear equations with crisp explanatory variables and fuzzy unknown variable vectors.
