Overview

What is he best known for?

The fields of study he is best known for:

  • Agriculture
  • Ecology
  • Agronomy

His primary areas of investigation include Agronomy, Crop, Anthesis, Crop yield and Poaceae. His studies in Phenology, Sowing, Crop simulation model, Dry matter and Biomass are all subfields of Agronomy research. John R. Porter interconnects Shoot and Vernalization in the investigation of issues within Phenology.

His biological study spans a wide range of topics, including Food security and Growing season. His work is dedicated to discovering how Crop, Canopy are connected with Phyllochron and Meristem and other disciplines. The various areas that John R. Porter examines in his Crop yield study include Agroforestry, Agriculture, Climate change, Precipitation and Greenhouse effect.

His most cited work include:

  • Temperatures and the growth and development of wheat: a review (701 citations)
  • Crop responses to climatic variation (666 citations)
  • Food security and food production systems (467 citations)

What are the main themes of his work throughout his whole career to date?

His main research concerns Agronomy, Climate change, Agriculture, Food security and Crop. His is doing research in Phenology, Crop yield, Anthesis, Poaceae and Sowing, both of which are found in Agronomy. His Climate change study integrates concerns from other disciplines, such as Economy and Precipitation.

His Agriculture research is multidisciplinary, relying on both Environmental resource management, Greenhouse gas and Agricultural economics. His Food security research incorporates elements of Food industry and Arable land. A large part of his Crop studies is devoted to Crop simulation model.

He most often published in these fields:

  • Agronomy (46.19%)
  • Climate change (34.52%)
  • Agriculture (28.93%)

What were the highlights of his more recent work (between 2012-2021)?

  • Climate change (34.52%)
  • Agriculture (28.93%)
  • Food security (25.89%)

In recent papers he was focusing on the following fields of study:

Climate change, Agriculture, Food security, Agronomy and Ecosystem services are his primary areas of study. His Climate change research integrates issues from Statistics, Propagation of uncertainty, Land use and Precipitation. His work on Organic farming and Agricultural productivity as part of general Agriculture study is frequently linked to Context, bridging the gap between disciplines.

His work in the fields of Food security, such as Food systems, intersects with other areas such as Research program. His study on Grain quality and Crop is often connected to Simulation modeling as part of broader study in Agronomy. John R. Porter has researched Crop in several fields, including Crop yield, Phenology and Sowing.

Between 2012 and 2021, his most popular works were:

  • Food security and food production systems (467 citations)
  • Temperatures and the growth and development of maize and rice: a review. (288 citations)
  • Simulation of Soil Organic Carbon Effects on Long-Term Winter Wheat (Triticum aestivum) Production Under Varying Fertilizer Inputs. (260 citations)

In his most recent research, the most cited papers focused on:

  • Agriculture
  • Ecology
  • Statistics

John R. Porter mainly focuses on Climate change, Agronomy, Food security, Agriculture and Crop. In the subject of general Climate change, his work in Climate commitment, Effects of global warming and Runaway climate change is often linked to Ambiguity, thereby combining diverse domains of study. His studies deal with areas such as Adaptation, Agricultural engineering and Global change as well as Agronomy.

His work on Food policy as part of general Food security research is often related to Library science, thus linking different fields of science. His studies in Agriculture integrate themes in fields like Futures studies and Agricultural economics. His Crop research is multidisciplinary, incorporating perspectives in Crop yield, Propagation of uncertainty and Sowing.
