Research.com Recognitions

  • 2025 - Research.com Plant Science and Agronomy in New Zealand Leader Award

Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Botany
  • Agronomy

His main research concerns Agronomy, Grazing, Lolium perenne, Pasture and Perennial plant. His Agronomy research is multidisciplinary, incorporating perspectives in Photosynthesis, Canopy photosynthesis, Herbivore, Respiration and Hectare. His study in Grazing is interdisciplinary in nature, drawing from both Irrigation management and Greenhouse gas.

Anthony J. Parsons interconnects Endophyte, Cultivar and Trifolium repens in the investigation of issues within Lolium perenne. His Pasture study integrates concerns from other disciplines, such as Agroforestry, Environmental management system, Irrigation, Agriculture and Foraging. His studies in Perennial plant integrate themes in fields like Stocking, Intake rate, Tiller and Biting.

His most cited work include:

  • Diet preference of sheep: effects of recent diet, physiological state and species abundance (285 citations)
  • Use of a model to optimize the interaction between frequency and severity of intermittent defoliation and to provide a fundamental comparison of the continuous and intermittent defoliation of grass (186 citations)
  • The physiology of grass production under grazing. II. Photosynthesis, crop growth and animal intake of continuously-grazed swards. (177 citations)

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

Anthony J. Parsons focuses on Agronomy, Grazing, Lolium perenne, Pasture and Ecology. His Agronomy study incorporates themes from Photosynthesis and Canopy photosynthesis. His Grazing research incorporates themes from Perennial plant, Stocking, Animal science, Herbivore and Forage.

The Lolium perenne study combines topics in areas such as Endophyte and Trifolium repens. His Pasture research is multidisciplinary, relying on both Soil organic matter, Nutrient, Foraging and Carbon cycle. In general Ecology, his work in Grassland, Abundance and Ecology is often linked to Generalist and specialist species and Spatial variability linking many areas of study.

He most often published in these fields:

  • Agronomy (59.26%)
  • Grazing (51.85%)
  • Lolium perenne (29.63%)

What were the highlights of his more recent work (between 2007-2012)?

  • Agronomy (59.26%)
  • Botany (16.67%)
  • Pasture (24.07%)

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

Anthony J. Parsons mostly deals with Agronomy, Botany, Pasture, Endophyte and Lolium perenne. Anthony J. Parsons conducts interdisciplinary study in the fields of Agronomy and Composition through his research. The study incorporates disciplines such as Soil organic matter, Soil carbon, Grazing and Soil retrogression and degradation in addition to Pasture.

His studies deal with areas such as Mycorrhiza, Cultivar and Herbivore as well as Endophyte. His Herbivore research is multidisciplinary, incorporating elements of Perennial plant, Ergovaline and Insect. In the subject of general Lolium perenne, his work in Neotyphodium is often linked to Metabolomics, thereby combining diverse domains of study.

Between 2007 and 2012, his most popular works were:

  • DairyMod and EcoMod: biophysical pasture-simulation models for Australia and New Zealand (150 citations)
  • Metabolic Profiles of Lolium perenne Are Differentially Affected by Nitrogen Supply, Carbohydrate Content, and Fungal Endophyte Infection (138 citations)
  • Past lessons and future prospects: plant breeding for yield and persistence in cool-temperate pastures (98 citations)

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

  • Ecology
  • Botany
  • Agriculture

His scientific interests lie mostly in Agroforestry, Agronomy, Lolium perenne, Botany and Neotyphodium. His research integrates issues of Environmental management system, Irrigation, Agriculture, Pasture and Greenhouse gas in his study of Agroforestry. His Agronomy research incorporates elements of Forage and Glomeromycota.

Anthony J. Parsons combines subjects such as Endophyte and Mycorrhiza with his study of Lolium perenne. The Botany study combines topics in areas such as Mannitol, Food science and Nutrient. His study on Neotyphodium is mostly dedicated to connecting different topics, such as Cultivar.
