World Online Ranking of Best Plant & Agronomy Scientists – 2024 Report
On April 30, 2024, Research.com published its third report on the best scientists in the field of plant science and agronomy. The yearly report seeks to raise awareness of scientists and their contributions to research that advances the technology and knowledge in plant and agronomy science.
Our research team intends to contribute to the scientific community with the 2024 version. Our directory of top experts in plant science and agronomy can be used by other scholars, academic institutions, and other organizations worldwide to find top scientists in their discipline.
We have tallied nearly 3,500 scientists found in Google Scholar and Microsoft Academic Graph and examined them using several indicators and metrics such as citations and awards. These helped us in considering each scientist's inclusion in the 2024 report. The D-index threshold for including a scientist was set to 30 if most of their publications were in the field of plant and agronomy science.
Latest discoveries in plant science & agronomy research
Plant science received a major boost with the discovery of root cortical aerenchyma (RCA). RCA refers to air pockets that develop within plant roots. This seemingly simple adaptation has big implications. RCA allows plants growing in waterlogged soils, where oxygen is scarce, to breathe. This not only improves plant survival but also potentially expands the range of cultivable land.
In the field of agronomy, regenerative agriculture has emerged as a game-changer. It focuses on improving soil health through practices like cover cropping, no-till farming, and compost application. This holistic approach not only enhances crop yields but also promotes biodiversity, reduces soil erosion, and improves water retention.
Research like RCA and regenerative agriculture paves the way for a more sustainable and productive future for agriculture. By understanding plant adaptations and developing practices that promote healthy soil ecosystems, scientists are empowering farmers to grow more food while protecting the environment.
