Simulation of Peanut Growth in Oklahoma

Abstract

This study is concerned with computer modeling of peanut growth in Oklahoma. Two peanut growth models from the southeast U.S. were modified and calibrated using sequential harvest data from four field sites in Caddo County, Oklahoma. After model parameters were developed for Oklahoma, the two models were used to simulate the effect of varying soil moisture availability and planting date. The model parameters presented herein are those that produced the best simulations of the field data on all four sites. Due to scatter in the field data, the best simulations do not fit all the data points but the trend of the data. Both models did a very good job of simulating pod growth, which is economically more important than vegetative growth.
