Research.com Recognitions

  • 2026 - Research.com Plant Science and Agronomy in United States Leader Award
  • 2016 - Fellow of the American Association for the Advancement of Science (AAAS)

Overview

What is he best known for?

The fields of study he is best known for:

  • Agriculture
  • Agronomy
  • Botany

P. V. Vara Prasad mainly investigates Agronomy, Horticulture, Sorghum, Pollen and Botany. His Agronomy research incorporates elements of Nutrient and Carbon dioxide. In the subject of general Carbon dioxide, his work in Carbon dioxide in Earth's atmosphere is often linked to Yield, thereby combining diverse domains of study.

His research in Sorghum intersects with topics in Crop productivity and Lipid composition. His Pollen study incorporates themes from Photosynthesis, Ecophysiology, Abiotic stress and Animal science. His studies deal with areas such as Thylakoid and Starch as well as Botany.

His most cited work include:

  • Temperature variability and the yield of annual crops (423 citations)
  • Adverse high temperature effects on pollen viability, seed-set, seed yield and harvest index of grain-sorghum (Sorghum bicolor (L.) Moench) are more severe at elevated carbon dioxide due to higher tissue temperatures (295 citations)
  • Effects of elevated temperature and carbon dioxide on seed‐set and yield of kidney bean (Phaseolus vulgaris L.) (210 citations)

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

His primary scientific interests are in Agronomy, Sorghum, Horticulture, Crop and Agriculture. His study ties his expertise on Pollen together with the subject of Agronomy. His study in Sorghum is interdisciplinary in nature, drawing from both Mesotrione, Vapour Pressure Deficit, Transpiration, Panicle and Hybrid.

His studies in Horticulture integrate themes in fields like Botany, Plant physiology and Sucrose. The various areas that P. V. Vara Prasad examines in his Crop study include Quantitative trait locus, Abiotic component, Nutrient and Phenology. His work on Conservation agriculture and Sustainable agriculture as part of his general Agriculture study is frequently connected to Business, thereby bridging the divide between different branches of science.

He most often published in these fields:

  • Agronomy (52.69%)
  • Sorghum (29.94%)
  • Horticulture (19.16%)

What were the highlights of his more recent work (between 2018-2021)?

  • Agronomy (52.69%)
  • Sorghum (29.94%)
  • Horticulture (19.16%)

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

P. V. Vara Prasad focuses on Agronomy, Sorghum, Horticulture, Agriculture and Crop. His work deals with themes such as Mesotrione, Biofuel, Nested association mapping and Hybrid, which intersect with Sorghum. His research in Horticulture intersects with topics in Photosynthesis, Genotype and Plant physiology.

The Sustainable agriculture research P. V. Vara Prasad does as part of his general Agriculture study is frequently linked to other disciplines of science, such as Business, therefore creating a link between diverse domains of science. He focuses mostly in the field of Grain filling, narrowing it down to topics relating to Germination and, in certain cases, Pollen, Vegetative reproduction and Point of delivery. His Cultivar research integrates issues from Bloom and Shoot.

Between 2018 and 2021, his most popular works were:

  • Drought and heat stress-related proteins: an update about their functional relevance in imparting stress tolerance in agricultural crops (31 citations)
  • Influence of drought and heat stress, applied independently or in combination during seed development, on qualitative and quantitative aspects of seeds of lentil (Lens culinaris Medikus) genotypes, differing in drought sensitivity. (26 citations)
  • Satellite-based soybean yield forecast: Integrating machine learning and weather data for improving crop yield prediction in southern Brazil (25 citations)
