  • 2016 - Fellow of the Australian Academy of Science

Overview

What is he best known for?

The fields of study he is best known for:

  • Agriculture
  • Botany
  • Agronomy

His scientific interests lie mostly in Agronomy, Canola, Botany, Glucosinolate and Crop. His Agronomy study incorporates themes from Soil water and Subsoil. The study of Canola is intertwined with the study of Horticulture in a number of ways.

His work deals with themes such as Biomass and Soil ecology, which intersect with Botany. His Glucosinolate research is multidisciplinary, incorporating perspectives in Green manure, Isothiocyanate, Shoot and Allelopathy. His work carried out in the field of Crop brings together such families of science as Agroforestry and Pasture.

His most cited work include:

  • MYC2 differentially modulates diverse jasmonate-dependent functions in Arabidopsis. (711 citations)
  • Traits and selection strategies to improve root systems and water uptake in water-limited wheat crops (441 citations)
  • Biofumigation potential of brassicas (370 citations)

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

John A. Kirkegaard focuses on Agronomy, Canola, Crop, Sowing and Soil water. His work in Pasture, Cultivar, Grazing, Brassica and Crop yield are all subfields of Agronomy research. His Canola research incorporates elements of Dry matter and Plant breeding.

His research in Crop intersects with topics in Agroforestry, Yield, Horticulture and Mixed farming. He has researched Sowing in several fields, including Weed, Summer fallow, Water-use efficiency, Phenology and Mediterranean climate. Root system is closely connected to Nutrient in his research, which is encompassed under the umbrella topic of Soil water.

He most often published in these fields:

  • Agronomy (73.64%)
  • Canola (34.55%)
  • Crop (31.36%)

What were the highlights of his more recent work (between 2017-2021)?

  • Agronomy (73.64%)
  • Sowing (24.09%)
  • Cultivar (14.55%)

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

His primary areas of study are Agronomy, Sowing, Cultivar, Agriculture and Agroforestry. His Agronomy study frequently draws connections to other fields, such as Soil water. His Sowing research includes themes of Cropping, Crop yield, Water-use efficiency and Growing season.

His Cultivar study combines topics from a wide range of disciplines, such as Subsoil, Phenology and Green manure. As a part of the same scientific family, John A. Kirkegaard mostly works in the field of Agroforestry, focusing on Conservation agriculture and, on occasion, Tillage, Winter rainfall, Soil carbon sequestration, Mixed farming and Weed. As part of one scientific family, he deals mainly with the area of Crop, narrowing it down to issues related to the Grazing, and often Forage.

Between 2017 and 2021, his most popular works were:

  • Early sowing systems can boost Australian wheat yields despite recent climate change (53 citations)
  • Fast winter wheat phenology can stabilise flowering date and maximise grain yield in semi-arid Mediterranean and temperate environments (32 citations)
  • The critical period for yield and quality determination in canola ( Brassica napus L.) (26 citations)

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

  • Agriculture
  • Botany
  • Ecology

John A. Kirkegaard spends much of his time researching Agronomy, Sowing, Cultivar, Crop and Agroforestry. His Agronomy study is mostly concerned with Canola and Tillage. His studies deal with areas such as Subsoil, Minimum tillage and Weed as well as Sowing.

His Cultivar research includes elements of Temperate climate, Phenology, Crop yield, Mediterranean climate and Yield. His Crop study integrates concerns from other disciplines, such as Brassicaceae, White mustard, Glucosinolate, Cover crop and Crucifer. His studies in Agroforestry integrate themes in fields like Agriculture, Digging and Root system.
