Crop Growth Simulation Models
1. Introduction Systems approach has been used by engineers since the 1950's for the study of complex and dynamic processes but their use by scientists working in biological fields is relatively recent. A system is defined as any well delineated part of reality which may contain a number of interrelated elements forming the systems structure. These functioning components interact in various way...
متن کاملRemote Sensing for Crop Growth and Crop Simulation Modeling
Crop yield is the result of complex interaction among factors of soil, atmosphere, plant genotype, and management practices adopted. These complex interactions of crop with various factors and of factors among themselves make the crop yield modeling a difficult task. Several methods of crop yield forecasting have been developed ranging from purely statistical to agro-meteorological to empirical...
متن کاملCrop Models as Decision Support Systems in Crop Production
The current challenges crop production faces in the context of required yield increases while reducing fertilizer, water and pesticide inputs have created an increasing demand for agronomic knowledge and enhanced decision support guidelines, which are difficult to obtain on spatial scales appropriate for use in a multitude of global cropping systems. Nowadays crop models are increasingly being ...
متن کاملHeteroskedasticity in Crop Yield Models
This study examines three alternative models of correcting for heteroskedasticity in wheat yield: the time trend variance, the GARCH, and an econometric model that includes the potential sources of heteroskedasticity. Nonnested test results suggest that modeling the sources of heteroskedasticity is the preferred procedure. Including potential sources of heteroskedasticity as explanatory variabl...
متن کاملCrop Models – Within Controlled Environment
Technology used in controlled environment facilities ranges from simple plastic row covers to sophisticated controlled and automated greenhouse and growth chambers. Crop models that estimate plant responses to climactic, nutritional, and other factors have been used to support controlled environment plant production at many of these technology levels. Such models typically consist of mathematic...
