Research/Extension Interests
. Achievements in Investigative Competency: Dr Reddy excels in several areas of plant science and agronomic fields. He made original and significant contributions to (a) medicinal herbs and controlling semiarid shrubs, (b) the development, testing and application of a cotton crop model, (c) remote sensing and plant stress physiology applications, and (d) global climate change biology and climate-ready crops. These areas of investigation often require three or four specialists. Dr. Reddy’s has made very impressive contributions by his original and creative approach to studying complex interactions of the crop-climate domain and demonstrated ways to develop the information for clientele. In addition, he is an excellent teacher and inspires those associated with him toward perfecting their skills. (a). Medicinal Herbs and Controlling Semiarid Scrubs: Dr. Reddy’s interest in research started very early in his career. His graduate work focused on the control of less productive semiarid shrub species through herbicidal means and is practiced widely today to control weedy native plants and replace them with more productive species adapted to that part of the world. Later he worked at the Biology Department of S.V. University, Tirupati, India, where he compiled medicinal and wild edible plants. He documented the use of about 216 formulations of plants products for medicinal purposes in the region. Their use had been handed over from generation to generation by oral communication, and thus there was either no written record or only limited documentation of plants used for medicinal purposes and Dr. Reddy’s work filled that void and brought into limelight of those formulation used by local tribes for further studies. (b). Crop Modeling and Applications: Crop management requires optimization of plant growth through interacting weather, soil and management factors. Producers and policy makers estimate growth, development and yield as a function of the soil-plant-atmosphere dynamics, with appropriate tools. Crop simulation models developed from quantitative data of physiological responses to weather and management practices allow estimates of crop responses to these factors on to regional assessments of the impact of climate variability and climate change. Dr. Reddy is widely recognized for the quality of his research in environmental physiology and in the development of mechanistic crop models that are being used by growers, scientists and policy makers in the U.S. and abroad. Through analysis of cotton grown in sun-lit plant growth chambers (SPAR units), Dr. Reddy developed crop functional algorithms that improved the functionality of crop models. The “environmental productivity index concept” that he introduced to quantify multiple environmental factors with quantitative measures of each stress factor intensity. This was instrumental not only in improving the functionality of the crop models but also expanded the utility of the models by a broader range of agencies and researchers around the country to study weather and management inputs including the USDA-ARS Cotton Modeling Group, Washington, D.C., the National Center for Atmospheric Research, Boulder, CO, the USDA-UV-B Monitoring and Network Program at Fort Collins, CO, and the Integrated Crop Management (ICM) systems group at Texas A&M University, TX. Producers and consultants are using the cotton model during the season for determining different management practices to optimize yields. The developed model combined with climate projection models are being used to assist policy decisions by federal agencies such as USDA. (c). Remote Sensing Applications: With his expertise in environmental plant physiology, Dr. Reddy assisted stress-specific remote sensing algorithms that helped determine more detailed physiological interpretation of the vegetation component of remotely sensed images. When merged with other field (e.g., weather, soil types, topography, and planting date) data, the interpretation provided by the new tools has the potential to generate crop health maps and assist in the development of early and timely detection of crop stress indicators for timely in-season management practices to optimize production conditions. (d). Plant Growth Regulators in Cotton Production: Dr. Reddy determined the response of cotton to PIX under different environmental conditions. PIX is a plant growth regulator that is used on approximately 80% of the cotton grown in Mississippi and approximately 50% of the cotton grown in the USA. PIX is applied by farmers to cotton in order to shorten stem growth reducing lodging and hasten maturity. Producers strive to provide essential fertilizer and water so that these do not become yield-limiting. However, if they are provided in excess, the crop may become too luxuriant under some weather conditions and lodge or provide an excellent environment for boll rot. Either lodging or boll rot may devastate a crop in the Midsouth. By the judicious application of PIX, these disadvantages of high production strategies may be reduced or avoided. Traditional methods required a lot of guess-work by the crop manager because the amount needed was a moving target depending on weather, crop growth stage and the fertility status of the crop. The new technique provides growers with appropriate crop growth stage and crop growth information regarding when and how much PIX should be applied to optimize cotton growth in each field situation. As a result of this information and the analysis developed, producers are able to greatly reduce much of the risks associated high-production strategies. This information has been combined with a daily weather network and is being used by many growers in South Texas and the Midsouth to manage their PIX applications. (e). Nutritional Aspects Crops: Because late season potassium (K) deficiency is becoming more widespread, attention is being refocused on the nutritional needs of cotton, particularly in transgenic varieties. The relationship between tissue K content and cotton growth is limited. With emphasis on site-specific agriculture, such information is needed to diagnose reasons for low producing areas. Dr. Reddy conducted experiments using the sunlit controlled chambers to determine growth rates and other growth related processes in response to different tissue K concentration (Not nutrient supply information). His overall goal of this project was to improve the profitability of US cotton producers by providing the tools and information in several different forms on how cotton plants respond to K-nutrition. He developed quantitative and pictorial information on cotton responses to K-nutrition using the naturally-lit environment-controlled-plant growth chambers and digital pictures. The information was published in Mississippi State University Experiment Station Bulletin, which has been awarded a Certificate of Excellence by the American Society of Agronomy for the Development of Outstanding Agronomic Educational Material at the national level. Extension agents across the US Cottonbelt are currently using that information for nutrient management. Currently, he is developing quantitative process-level data for various nutrients, nitrogen and phosphorus, in crops and to relate to remote sensing algorithms in plants. He has developed a new concept known as environmental productivity index concept to explain how multiple stress factors will influence plant growth and development. This information is particularly important for producers and consultants with methods and tools to devise best management options in multiple cropping systems. (f). Global Climate Change Biology: Dr. Reddy is a recognized authority on how the expected global climate change will affect major agricultural crops in general, and in particular how crops will respond to increased greenhouse gases in the atmosphere. Dr. Reddy’s research has been adopted in two unique ways, experimentation and modeling. The environmental physiology research using the sunlit controlled environment facility has determined responses of crops to various environmental variables and their interactions that are expected to change due to global warming. It was widely assumed in the agricultural and scientific communities that increasing atmospheric CO2 caused by human activity would result in higher rates of photosynthesis and increased growth of agricultural crops (cotton, soybean, cowpeas, sweetpotato, etc.) as well as of unmanaged vegetation (Big Bluestem) has confirmed this is true when plants are grown in nearly optimum conditions. However, when plants are grown in less than optimum conditions, they respond only marginally to increases in CO2. However, his research on various crop species and native grass species resulted in ‘rule of thumb’ that projections yield of seed crops will decrease in seed production by 10% per every degree rise in temperature above optimum. This finding is very important in the context of climate change as we expect frequent and more severe heat waves and other vagaries that may severely impact food production. More importantly, the improved cotton crop model integrated with climate prediction models by other agencies is being used for to assist policy decisions on projected climate change impacts on regional basis. Very few people around the world are conducting such research and Dr. Reddy is among the few scientists with international recognition in this field. The uniqueness and quality of this information are being recognized worldwide, and Dr. Reddy has been invited to speak on the impact of the hypothesized global climate change at several national and international gatherings. As a result, approximately 50 scientists from throughout the world were selected to contribute to a comprehensive treatment of Climate Change and Global Crop Productivity published by CAB International, UK. (g). Climate-Ready Crops: Crops in the future will be grown in a much different environment than today. Abiotic stresses and climate variability, which are projected to increase more in the future climate, are projected to cause extensive damage to crop yield and quality. Cultivars with enhanced resilience to multiple abiotic stress conditions will be highly valued. Dr. Reddy and his group have devised several physiological and reproductive tools and techniques using pollen vitality and other yield limiting characteristics to screen numerous crop (cotton, corn, rice, soybean, canola, peppers, cowpeas, etc.) cultivars to a number of abiotic (temperature, drought and Ultraviolet-B radiation, either alone or in combination) stresses. These studies provide crop breeders tools and cultivars to develop climate-ready crops. This is important because we need cultivars to be more productive to meet the increasing demand for food production for increasing global population and in securing food security. (h). Publications and Outreach Activities: Dr. Reddy reaches stakeholders by publishing his research in several avenues: (a) Books edited: 1; (b) Chapters of books: 30, (c) Refereed journals: 108, (d) Proceeding, popular and technical reports: 82, (e) Web-based articles and bulletins: 3, (f) Invited lectures: 83, and (g) symposia presentations: 228. His grants since 2008 as PI and Co-PI to support his research have totaled $5,734,524. Because of his high impact research, Dr. Reddy has been recognized several times by his peers including the Ralph Powe Research Excellence Award, the Highest Mississippi State University Research Honor (2012); MSU State Pride Awards (2010, 2011), CALS Science Award for Outstanding Scientific Publications (2012, 2002), Award of Excellence, Outstanding Work in MAFES (2006); Fellow, Crop Science Society of America (2006); Fellow, American Society of America (2005); Alumni Award for Excellence from S.V. University, India (2005); Career Award in Research, Southern Branch of the American Society of Agronomy (2004); Outstanding Agricultural Scientist Award, Association of Agricultural Scientists of Indian Origin (2004) for his contributions.
