Crop Simulation and Growth Modeling

Slide-13-Body-300x294The increased concentration of carbon dioxide and other green house gases are expected to increase the temperature of earth. Crop production is highly dependent on variation in weather and therefore any change in global climate will have major effects on crop yields and productivity. Elevated temperature and carbon dioxide affects the biological processes like respiration, photosynthesis, plant growth, reproduction, water use etc. In case of rice increased carbon dioxide levels results in larger number of tillers, greater biomass and grain yield. Similarly, in groundnut increased carbon dioxide levels results in greater biomass and pod yields.

However, in tropics and sub-tropics the possible increase in temperatures may offset the beneficial effects of carbon dioxide and results in significant yield losses and water requirements. Proper understanding of the effects of climate change helps scientists to guide farmers to make crop management decisions such as selection of crops, cultivars, sowing dates and irrigation scheduling to minimize the risks. In recent years there has been a growing concern that changes in climate will lead to significant damage to both market and non-market sectors. The climate change will have a negative effect in many countries. Adaptation to climate change-through changes in farming practices, cropping patterns, and use of new technologies will help to ease the impact.

Remote Grid can integrate established crop models into its existing decision support systems to monitor the growth conditions and alert in events of variability in environmental conditions, so that timely intervention can be taken.
