2. Information on the Simpotato configuration so users can change how the model runs and what output it produces.
3. Information to understand the graphical output produced by the model This document discusses version 1.60 of the SIMPOTATO model (3,5,7-11,14) for Windows 95. Simpotato is derived from version 2 of the CERES (2,12,13,15,16) family of models. SIMPOTATO is a potato growth simulation model. It is intended for a wide range of applications such as 1) at the farm level: irrigation and fertilizer scheduling on individual fields, predicting yield response to irrigation and fertilization regimes, estimating movement of water and nitrogen below the root zone in response to various levels of applied water and nitrogen, estimating economic benefit of supplemental applied water and nitrogen, estimating distribution of nitrogen in the soil during the growing season and after crop maturity; 2) at the regional level: estimating yield potential for the regional climate and soil types, estimating regional irrigation and nitrogen requirements for various yield levels, estimating potential nitrogen loading to ground water; and 3) as a research tool: testing hypotheses as to how environmental factors (light, temperature, water, nitrogen) interact with plant physiological processes to determine growth, development, and yield. Currently I am distributing version 1.60 of Simpotato for Windows 95 on my ftp site or on a floppy disk by mail. Email me about obtaining the GUICS Graphical User Interface program for Crop Simulation models (Pachefsky and Mironenko). Following are instructions for installing GUICS, installing Simpotato into GUICS, and installing Simpotato as a separate program.
