Overview

What is he best known for?

The fields of study he is best known for:

  • Botany
  • Agronomy
  • Ecology

R. J. Summerfield focuses on Agronomy, photoperiodism, Sowing, Botany and Cultivar. His Germination and Vigna study in the realm of Agronomy connects with subjects such as Relative humidity. His photoperiodism research incorporates elements of Germplasm, Phenology, Plant breeding, Light effect and Poaceae.

His Sowing study integrates concerns from other disciplines, such as Crop and Plant physiology. He mostly deals with Environmental factor in his studies of Botany. His Cultivar research is multidisciplinary, incorporating perspectives in Animal husbandry and Maturity.

His most cited work include:

  • The Influence of Temperature on Seed Germination Rate in Grain Legumes I. A COMPARISON OF CHICKPEA, LENTIL, SOYABEAN AND COWPEA AT CONSTANT TEMPERATURES (260 citations)
  • The Influence of Temperature on Seed Germination Rate in Grain Legumes II. INTRASPECIFIC VARIATION IN CHICKPEA (Cicer arietinum L.) AT CONSTANT TEMPERATURES (184 citations)
  • FRUIT NUMBER IN RELATION TO POLLEN PRODUCTION AND VIABILITY IN GROUNDNUT EXPOSED TO SHORT EPISODES OF HEAT STRESS (165 citations)

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

His primary areas of investigation include Agronomy, photoperiodism, Sowing, Horticulture and Botany. Many of his studies involve connections with topics such as Tropics and Agronomy. His photoperiodism course of study focuses on Phenology and Crop production.

His Sowing research incorporates themes from Plant physiology, Panicle, Crop and Plant breeding. R. J. Summerfield usually deals with Horticulture and limits it to topics linked to Environmental factor and Point of delivery. When carried out as part of a general Botany research project, his work on Ecophysiology, Dry matter and Germination is frequently linked to work in Longevity, therefore connecting diverse disciplines of study.

He most often published in these fields:

  • Agronomy (57.38%)
  • photoperiodism (42.62%)
  • Sowing (42.62%)

What were the highlights of his more recent work (between 1995-2016)?

  • Sowing (42.62%)
  • Agronomy (57.38%)
  • Horticulture (39.34%)

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

His primary scientific interests are in Sowing, Agronomy, Horticulture, photoperiodism and Botany. His Sowing study combines topics from a wide range of disciplines, such as Sativum, Cultivar, Crop, Tropics and Plant physiology. His Cultivar research focuses on subjects like Point of delivery, which are linked to Dry weight.

The various areas that R. J. Summerfield examines in his Agronomy study include Agriculture and Temperate climate. His photoperiodism research is multidisciplinary, incorporating elements of Inflorescence, Sorghum, Maturity and Phenology. His Field experiment research extends to Botany, which is thematically connected.

Between 1995 and 2016, his most popular works were:

  • FRUIT NUMBER IN RELATION TO POLLEN PRODUCTION AND VIABILITY IN GROUNDNUT EXPOSED TO SHORT EPISODES OF HEAT STRESS (165 citations)
  • Effects of short episodes of heat stress on flower production and fruit‐set of groundnut (Arachis hypogaea L.) (134 citations)
  • Effect of Temperature and Water Deficit on Water‐Use Efficiency, Carbon Isotope Discrimination, and Specific Leaf Area in Peanut (111 citations)

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

  • Botany
  • Ecology
  • Agronomy

Agronomy, Sowing, Horticulture, Environmental factor and Botany are his primary areas of study. His Agronomy study incorporates themes from Tropics and photoperiodism. His studies deal with areas such as Sorghum, Maturity and Phenology as well as photoperiodism.

His work carried out in the field of Sowing brings together such families of science as Plant production and Crop. His research integrates issues of Dry matter, Point of delivery and Cultivar in his study of Environmental factor. His study in Growing season and Germination falls within the category of Botany.
