    Coupling Source Strength to Yield Potential Photosynthesis is one of the most widely studied plant processes and has gained renewed focus in efforts to increase yields Stitt et al. Characterizing the Source-Path-Sink Despite a functional understanding of how photoassimilates are packaged and transported to sink tissues, characterizing the activity of post-photosynthetic processes that exhibit governance over yield development is rare. Edited by: Jairo A. After Dr. There was a vacant staff position for a soil scientist. Baker applied and got the job. Continue your research in crop canopy photosynthesis.

    So Baker began studying crop canopy light interception and photosynthesis. Having grown up on a farm, he wanted to render basic science in plant physiology useful in production agriculture — which, even today, is not commonly done. He saw the value in evaluating and quantifying how various physiological processes result in crop growth and yield. Two such processes are the exchanges of carbon dioxide and water vapor. Baker began working with producers across the Mississippi Delta to apply his theories.

    He knew the two primary physiological processes impacting crop growth and yield were the exchange of carbon dioxide and water vapor. Cotton starts developing slowly, but by the time it hits the eighth or ninth node, it really takes off. Baker and his team began working with Extension specialists and cotton producers across the Cotton Belt to apply these models as crop management decision support systems. Beyond their value in crop management, these models are useful in predicting the effects of climate change including higher atmospheric carbon dioxide concentrations on crop yield and water use.

    Raja Reddy, a research professor, oversees the facility. Ambient noises from the control room inside the North Farm facility resemble sounds emanating from an operating room, but those sounds are coming from the 60 channel switch boxes controlling each of the individual environments within each SPAR unit. Desktop computers are interfaced with controller mechanisms, each recording different pieces of information every 15 minutes, 24 hours a day, thanks to more than crop monitoring sensors and instruments in the units.

    Baker knows and wants to emphasize that there is a good side to increased carbon dioxide concentration — higher possible yields for crops. Reddy is continuing today, we can document proof of that and quantify it as well — which is very important when we give this information to our Extension people who can then relate it to our farmers and policymakers.

    The beauty of this research lies in the ability to look at past weather data, and say with confidence that if weather is similar in the future, a grower might expect a crop to grow a certain way — based on what the models simulated during that weather phase. The computers controlling the SPAR units are essentially playing a game, adding or taking away any certain input until the crop no longer responds to it.
