Changes in Management Can Improve Returns from Cambodian Upland Crops [PDF]

Farming systems research for wet-season non-rice upland crops in Cambodia is being conducted with the overall aim of poverty reduction and food security for farmers in the Provinces of Battambang and Kampong Cham. Some of these cash crops exhibit low and

gym-DSSAT: a crop model turned into a Reinforcement Learning environment

, 2022
La résolution d’un problème de déecision séquentielle en conditions réelles s’appuie très souvent sur l’utilisation d’un simulateur qui reproduit ces conditions réelles. Nous introduisons un nouvel environnement pour l’apprentissage par renforcement (AR) qui propose des tâches d’apprentissage réalistes pour la conduite de cultures.

Improving Crop Models: Incorporating New Processes, New Approaches, and Better Calibrations [PDF]

, 2014
Early ancestors of crop simulation models (De Wit, 1965; Monteith, 1965; Duncan et al., 1967) were born before primitive personal computers were available (e.g. Apple II released in 1977, IBM PC released in 1981).
