Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Botany
  • Agronomy

Toshihiro Hasegawa mainly focuses on Agronomy, Oryza sativa, Animal science, Photosynthesis and Carbon dioxide. Agronomy and Canopy are commonly linked in his work. His research in Oryza sativa intersects with topics in Grain yield, Poaceae and Cultivar.

His Cultivar study integrates concerns from other disciplines, such as Japonica, Tiller and Seedling. His Botany research extends to Animal science, which is thematically connected. Toshihiro Hasegawa works mostly in the field of Carbon dioxide, limiting it down to topics relating to Respiration and, in certain cases, Carbon assimilation.

His most cited work include:

  • Increasing CO2 threatens human nutrition (572 citations)
  • Soil organic carbon stocks in China and changes from 1980s to 2000s (255 citations)
  • Uncertainties in Predicting Rice Yield by Current Crop Models Under a Wide Range of Climatic Conditions (232 citations)

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

The scientist’s investigation covers issues in Agronomy, Oryza sativa, Paddy field, Cultivar and Horticulture. His work deals with themes such as Photosynthesis, Canopy and Climate change, which intersect with Agronomy. In his study, which falls under the umbrella issue of Oryza sativa, Growing season is strongly linked to Carbon dioxide.

His Paddy field research includes themes of Atmosphere, Soil test, Incubation, Methane and Environmental chemistry. Toshihiro Hasegawa has included themes like Japonica, Yield and Sowing in his Cultivar study. As a part of the same scientific family, he mostly works in the field of Horticulture, focusing on Botany and, on occasion, Animal science.

He most often published in these fields:

  • Agronomy (58.57%)
  • Oryza sativa (25.24%)
  • Paddy field (20.48%)

What were the highlights of his more recent work (between 2016-2021)?

  • Agronomy (58.57%)
  • Climate change (14.29%)
  • Oryza sativa (25.24%)

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

His primary scientific interests are in Agronomy, Climate change, Oryza sativa, Horticulture and Cultivar. His work on Grain quality, Crop and Growing season as part of general Agronomy research is often related to Water temperature, thus linking different fields of science. His Climate change research incorporates elements of Canopy, Paddy field, Environmental resource management and Yield.

His Oryza sativa study combines topics in areas such as Panicle, Livestock and Grain yield. He combines subjects such as Pollen, Pollination, Sterility and Human fertilization with his study of Horticulture. His Cultivar research is multidisciplinary, incorporating perspectives in Japonica and High yielding.

Between 2016 and 2021, his most popular works were:

  • Quantitative trait loci for large sink capacity enhance rice grain yield under free-air CO2 enrichment conditions. (28 citations)
  • Increasing canopy photosynthesis in rice can be achieved without a large increase in water use–a model based on free-air CO2 enrichment (26 citations)
  • Combined drought and heat stress impact during flowering and grain filling in contrasting rice cultivars grown under field conditions (23 citations)

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

  • Ecology
  • Botany
  • Agriculture

His scientific interests lie mostly in Cultivar, Oryza sativa, Agronomy, Horticulture and Climate change. The concepts of his Cultivar study are interwoven with issues in Japonica and Co2 concentration. His studies deal with areas such as Pollination, Sterility, Grain yield, Crop yield and Stamen as well as Oryza sativa.

He performs multidisciplinary study in Agronomy and Distribution in his work. His work on Yield as part of his general Horticulture study is frequently connected to Rice straw, Mineral deficiency and Soluble oxalate, thereby bridging the divide between different branches of science. The Climate change study combines topics in areas such as Soil science, Scale and Yield.
