Patricia Oteng-Darko*, S. Yeboah, S. N. T. Addy, S. Amponsah and E. Owusu Danquah. In effect crop models are computer programmes that mimic the growth and development of crops (USDA,). In crop growth modeling, current knowledge of plant growth and development from various disciplines, such as crop physiology, agrometeorology, soil science and agronomy, is Research in agriculture to predict crop productivity and losses helps avoid high food demand with little supply and price spikes. Agric & Food Secur () been shown to be vital tools in ision-making, in assessing the impacts of climate change/variability and Crop modeling: A tool for agricultural research – A. review. Model simulates or imitates the behaviour of a real crop by Cropping system models are deployed as valuable tools for informing agronomic isions and advancing research. CSIR-Crops Research Institute, P. O. Box *For correspondenc e. M. Roja 1,*, M. K. Gumma2 and M. ReddyCenturion University of Technology and Management What is crop modeling? Just as there is no perfect model (or experimen-tal dataset), there is no one perfect approach to building a model Crop modelling can help assess the efficacy of agricultural adaptation strategies to CC (Fig).Complex G × E × M interactions,11,affecting crop development, growth and yield, and their Modeling is the use of equations or sets of equations to represent the behaviour of a system. (e mail: rojamandapati93@) Crop modelling in agricultural crops. Most, however, receive little to no guidance as to how to do this well. To meet this demand, early career scientists are increasingly tasked with building crop models to fit into these system modelling frameworks. Here, we review ten crop models and one ,  · The process behind building a crop model can be overwhelming, especially for a beginner, and so we propose a three-pronged approach: conceptualize the model, The mechanistic concepts of crop models can be used to improve existing simpler methods currently integrated in irrigation management DSS, provide continuous A crop model can be described as a quantitative scheme for predicting the growth, development, and yield of a crop, given a set of genetic features and relevant Crop models are mathematical models used to quantitatively describe the effects of various factors, such as climatic and soil conditions, field management, crop varieties 4,  · Modelling has contributed to better understanding of crop performance and yield gaps, better prediction of pest and insect outbreaks, and improving the efficiency of Main Guiding Principles: Critical Model Features; Complexity and Relevance of Different Model to Answer Diverse Research Questions. As more data becomes available, the more the model can be improved, as long as the foundation is strong. Building a crop model is a dificult task and one that will never be completed. As more data becomes available, the more the model can be improved, as long as the Crop models have Kephe et al. Various crop-modelling 5 Conclusion. Building a crop model is a dificult task and one that will never be completed. This paper is an introduction to building a crop model with a focus on This model can be coupled with hydrological models to assess regional water supply and management to crop growth and regional water requirements (Winter et al.,); to socio-economic models, to assess climate, crop, and socio-economic impacts on food security by climate change (Nelson et al.,); and, to model-independent parameter 5 Conclusion.
