John B. Passioura

What is he best known for?

The fields of study he is best known for:

• Agriculture
• Agronomy
• Botany

His scientific interests lie mostly in Agronomy, Water use, Root system, Crop and Shoot. Many of his studies on Agronomy apply to Soil water as well. He usually deals with Water use and limits it to topics linked to Anthesis and Plant nutrition, Plant breeding, Xylem and Animal breeding.

His work carried out in the field of Root system brings together such families of science as Data flow model, Dry soil and Soil science. His Crop research is multidisciplinary, incorporating perspectives in Cactus, Crop yield, Subsoil and Water supply. His Shoot research incorporates elements of Soil volume, Plant growth, Nutrient and Bulk density.

His most cited work include:

• Grain yield, harvest index, and water use of wheat. (493 citations)
• Roots and drought resistance (411 citations)
• Soil water status affects the stomatal conductance of fully turgid wheat and sunflower leaves (376 citations)

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

John B. Passioura focuses on Agronomy, Xylem, Soil water, Botany and Shoot. His Crop, Poaceae and Water use study in the realm of Agronomy connects with subjects such as Ecophysiology. The concepts of his Xylem study are interwoven with issues in Transpiration stream, Osmotic pressure and Hordeum vulgare.

His work focuses on many connections between Osmotic pressure and other disciplines, such as Turgor pressure, that overlap with his field of interest in Cell wall. His study in the field of Soil organic matter and Soil fertility is also linked to topics like Soil salinity control and Abscisic acid. His study in the field of Epidermis also crosses realms of Plant biology and Cell expansion.

He most often published in these fields:

• Agronomy (46.99%)
• Xylem (22.89%)
• Soil water (22.89%)

What were the highlights of his more recent work (between 2012-2020)?

• Agronomy (46.99%)
• Soil water (22.89%)
• Agriculture (13.25%)

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

His primary scientific interests are in Agronomy, Soil water, Agriculture, Soil science and Yield. His research on Agronomy frequently connects to adjacent areas such as Nutrient. His Soil water research includes themes of Xylem and Arable land.

His Agriculture research incorporates themes from Natural resource economics and Water-use efficiency. His study on Subsoil is often connected to Feed forward, Hydrostatic pressure and Water flow as part of broader study in Soil science. His studies in Yield integrate themes in fields like Agroforestry, Water deficit, Sowing, Plant breeding and Crop yield.

Between 2012 and 2020, his most popular works were:

• Nutrient availability limits carbon sequestration in arable soils (140 citations)
• Yield improvement and adaptation of wheat to water-limited environments in Australia—a case study (74 citations)
• Osmotic adjustment and energy limitations to plant growth in saline soil. (72 citations)

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

• Agriculture
• Botany
• Ecology

The scientist’s investigation covers issues in Agronomy, Arable land, Soil organic matter, Soil water and Phosphorus. John B. Passioura combines topics linked to Agriculture with his work on Agronomy. He has researched Arable land in several fields, including Nutrient and Straw.
