Overview

What is he best known for?

The fields of study he is best known for:

  • Agriculture
  • Ecology
  • Agronomy

His main research concerns Agronomy, Sorghum, Crop, Poaceae and Plant breeding. His Agronomy study integrates concerns from other disciplines, such as Soil water and Transpiration. His work on Sweet sorghum as part of general Sorghum research is often related to Plant level, thus linking different fields of science.

His study on Crop also encompasses disciplines like

  • Tropics which intersects with area such as Subtropics and Phenology,
  • Biomass partitioning and Predictability most often made with reference to Agricultural engineering. His Poaceae research includes themes of Coleoptile, Herbaceous plant and Germination. His studies in Plant breeding integrate themes in fields like Quantitative genetics, Genetic model, Biotechnology and Selection.

His most cited work include:

  • APSIM: a novel software system for model development, model testing and simulation in agricultural systems research (709 citations)
  • APSIM - Evolution towards a new generation of agricultural systems simulation (689 citations)
  • Greater sensitivity to drought accompanies maize yield increase in the U.S. Midwest (490 citations)

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

Graeme L. Hammer spends much of his time researching Agronomy, Sorghum, Crop, Plant breeding and Horticulture. His work carried out in the field of Agronomy brings together such families of science as Soil water, Canopy and Transpiration. His Sorghum research is multidisciplinary, relying on both Water use, Poaceae, Hybrid and Phenology.

His study in Crop is interdisciplinary in nature, drawing from both Agroforestry, Cultivar, Biomass, Crop yield and Agricultural engineering. His Plant breeding study combines topics from a wide range of disciplines, such as Adaptation, Biotechnology, Selection and Gene–environment interaction. His work deals with themes such as Cropping and Yield, which intersect with Sowing.

He most often published in these fields:

  • Agronomy (55.38%)
  • Sorghum (35.17%)
  • Crop (27.03%)

What were the highlights of his more recent work (between 2013-2021)?

  • Agronomy (55.38%)
  • Sorghum (35.17%)
  • Crop (27.03%)

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

His scientific interests lie mostly in Agronomy, Sorghum, Crop, Canopy and Trait. His Agronomy study frequently intersects with other fields, such as Transpiration. His Sorghum research includes elements of Quantitative trait locus, Biotechnology, Grain yield and Remote sensing.

His Crop study incorporates themes from Agroforestry, Agricultural engineering and Germplasm. His study looks at the relationship between Canopy and topics such as Leaf area index, which overlap with Productivity. His Plant breeding research includes elements of Adaptation and Selection.

Between 2013 and 2021, his most popular works were:

  • APSIM - Evolution towards a new generation of agricultural systems simulation (689 citations)
  • Greater sensitivity to drought accompanies maize yield increase in the U.S. Midwest (490 citations)
  • Drought adaptation of stay-green sorghum is associated with canopy development, leaf anatomy, root growth, and water uptake (162 citations)

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

  • Agriculture
  • Ecology
  • Agronomy

Graeme L. Hammer mainly focuses on Agronomy, Sorghum, Crop, Water use and Yield. Agronomy connects with themes related to Canopy in his study. His work carried out in the field of Sorghum brings together such families of science as Quantitative trait locus, Genotype, NODAL, Tiller and Environmental impact of agriculture.

The Crop study combines topics in areas such as Global warming and Agricultural engineering. His Water use study combines topics in areas such as Soil water, Water-use efficiency and Transpiration. His Yield research integrates issues from Epistasis, Zea mays and Crop yield.
