Overview

What is he best known for?

The fields of study he is best known for:

  • Agronomy
  • Botany
  • Ecology

Agronomy, Crop, Transpiration, Soil water and Crop yield are his primary areas of study. His research integrates issues of Nitrogen fixation and Plant physiology in his study of Agronomy. His Crop study integrates concerns from other disciplines, such as Biomass, Biotechnology, Grain yield and Yield.

Thomas R. Sinclair has included themes like Zea mays, Hybrid, Horticulture and Water content in his Transpiration study. His Soil water research incorporates themes from Greenhouse, Dehydration and Ecophysiology. His Crop yield research includes themes of Sorghum and Leaf area index.

His most cited work include:

  • Leaf Nitrogen, Photosynthesis, and Crop Radiation Use Efficiency: A Review (849 citations)
  • Efficient Water Use in Crop Production: Research or Re‐Search? (692 citations)
  • Radiation Use Efficiency (642 citations)

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

Thomas R. Sinclair focuses on Agronomy, Transpiration, Soil water, Crop and Botany. His Agronomy study frequently links to related topics such as Nitrogen fixation. The various areas that Thomas R. Sinclair examines in his Nitrogen fixation study include Respiration, Shoot and Plant physiology.

Many of his research projects under Transpiration are closely connected to Trait with Trait, tying the diverse disciplines of science together. His Soil water research is multidisciplinary, incorporating elements of Arachis hypogaea, Greenhouse and Water content. His Botany research integrates issues from Animal science, Nutrient and Horticulture.

He most often published in these fields:

  • Agronomy (67.53%)
  • Transpiration (28.31%)
  • Soil water (20.26%)

What were the highlights of his more recent work (between 2015-2021)?

  • Agronomy (67.53%)
  • Transpiration (28.31%)
  • Vapour Pressure Deficit (14.55%)

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

His primary scientific interests are in Agronomy, Transpiration, Vapour Pressure Deficit, Crop yield and Drought tolerance. His Agronomy study frequently draws connections to other fields, such as Soil drying. His study in Transpiration is interdisciplinary in nature, drawing from both Horticulture, Wilting, Soil water and Aquaporin.

His research in Soil water intersects with topics in Drought stress and Water content. His Crop yield study incorporates themes from Photosynthesis and Growing season. The concepts of his Drought tolerance study are interwoven with issues in Quantitative trait locus, Nitrogen fixation and Germplasm.

Between 2015 and 2021, his most popular works were:

  • Comparing and combining process-based crop models and statistical models with some implications for climate change (42 citations)
  • Limited-transpiration response to high vapor pressure deficit in crop species (42 citations)
  • Aquaporin Activity to Improve Crop Drought Tolerance (29 citations)

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

  • Botany
  • Ecology
  • Agronomy

Thomas R. Sinclair mainly investigates Agronomy, Transpiration, Vapour Pressure Deficit, Crop yield and Cultivar. Many of his studies on Agronomy involve topics that are commonly interrelated, such as Soil water. Thomas R. Sinclair has researched Transpiration in several fields, including Aquaporin and Drought tolerance.

He focuses mostly in the field of Vapour Pressure Deficit, narrowing it down to matters related to Water use and, in some cases, Growing season, Stomatal conductance and Food security. His Crop yield study combines topics from a wide range of disciplines, such as Water deficit, Water conservation, Grain yield, Crop growth and Nutrient. His studies examine the connections between Legume and genetics, as well as such issues in N2 Fixation, with regards to Botany.
