His primary scientific interests are in Food security, Agronomy, Soil water, Food processing and Ecology. His study in Food security is interdisciplinary in nature, drawing from both Agricultural land, Sustainability, Crop and Agricultural economics. His Agronomy research is multidisciplinary, incorporating elements of Leaching model and Dwarfing.
His studies in Soil water integrate themes in fields like Water use, Agriculture, Agroforestry and Water content. The various areas that Peter J. Gregory examines in his Food processing study include Natural resource economics, Biotechnology and Food systems. His work on Nutrient and Climate change as part of general Ecology study is frequently linked to Discretization and Field, bridging the gap between disciplines.
The scientist’s investigation covers issues in Agronomy, Agroforestry, Agriculture, Root system and Soil water. His Agronomy research includes themes of Nutrient and Plant physiology. His Agroforestry research incorporates themes from Sustainable agriculture and Climate change.
His work on Food security as part of general Agriculture research is frequently linked to Social policy and Context, thereby connecting diverse disciplines of science. His Food security study integrates concerns from other disciplines, such as Sustainability and Environmental planning. The concepts of his Root system study are interwoven with issues in Anthesis, Water-use efficiency and Hordeum vulgare.
His main research concerns Agronomy, Climate change, Agroforestry, Agriculture and Food security. His studies in Water-use efficiency, Shoot, Root system, Crop and Anthesis are all subfields of Agronomy research. His Climate change study combines topics in areas such as Cropping and Livestock.
His work carried out in the field of Agroforestry brings together such families of science as Crop quality, Crop yield, Crop production, Mixed farming and Greenhouse gas. His research in Food security intersects with topics in Biotechnology, Food processing, Soil fertility and Soil processes. Land use and Agricultural land is closely connected to Food industry in his research, which is encompassed under the umbrella topic of Food processing.
Peter J. Gregory mainly investigates Shoot, Water-use efficiency, Agronomy, Natural resource economics and Biotechnology. His studies deal with areas such as Canopy, Leaf area index, Root system and Drought tolerance as well as Shoot. His Water-use efficiency study combines topics from a wide range of disciplines, such as Tiller, Anthesis and Seedling.
The Natural resource economics study combines topics in areas such as Food processing, Soil fertility, Soil processes and Food fortification. His Soil processes study incorporates themes from Agricultural land and Food security. His Biotechnology research includes elements of Micronutrient deficiency, Biofortification, Crop and Food systems.
