dc.description.abstract | This is the reproduction of an observed phenomenon (e.g., growth of biomass with time; water use by a growing crop etc.,) by developing a model and a computer programme written for it. Such a programme usually is comprised of mathematical, statistical, physical, graphical or empirical expressions relating the various parameters given as input information or data. Model is a concept; simulation helps reproduction of a system in the laboratory using the concept;; could contain measurable or estimated parameter values or both. Most often, the computer programme written for any particular purpose is itself called a model. Crop-environment interactions are unlimited in number. They can be studied from several points of view (physical, physiological, chemical, biochemical, bio-technological, agronomical, entomological or pathological, economic benefit angles etc.,). We have the roots growing with passage of time and interacting with soil, taking up water and nutrients for transport to the aboveground parts of a plant. The stem, branches, leaves as they grow interact with environment (both individually and together), under the influence of solar radiation to produce flowers and pods / oils, 2 grains— ultimately yield. Evapotranspiration, Leaf-air interactions, Photosynthesis, respiration, carbon dioxide assimilation, are the other processes involved in crop growth. Crop is also affected by pest/disease incidence. Thus crop growth is usually viewed as a “complex system” which comprises of “sub-systems” in which several processes take place. One process leads to the other and so, individual processes (water or nutrient uptake by roots, biomass accumulation, grain growth etc.,) are considered as “sub-systems”. All the processes which interact among themselves (since the start of growth of plant from seeding to final yield) and put together are considered as a “system”. Thus one can have “sub-models” as part of a “model”, “sub-systems” and a “System”. One can simulate water uptake, branching pattern and growth, leaf development, pod growth, etc. and their interaction with soil and aerial environment, as individual models. The point to note is that there is no limit to the items that can be taken up to develop a simulation model. | en_US |
