About

V. Vijayakumar is an emerging researcher at the forefront of precision agriculture, with a specialized focus on smart spraying technologies, AI-driven weed detection, and robotic systems for sustainable crop management. His work addresses one of agriculture's most pressing challenges — efficient, targeted weed control that minimizes herbicide use while maximizing crop yield. Vijayakumar's most influential contribution, a 2023 comprehensive review of smart spraying technologies for precision weed management, has rapidly accumulated 64 citations, establishing him as a key synthesizer of knowledge in this field. Drawing on 114 articles from Google Scholar and Scopus, this work provides an authoritative assessment of state-of-the-art technologies, their benefits, and limitations — serving as an essential reference for researchers and practitioners alike. His more recent investigations push these boundaries further, developing AI-driven real-time weed detection systems, PI-controlled robotic sprayers with multi-nozzle integration, and low-cost autonomous spraying platforms tested in specialty crops such as pepper and tomato. These contributions collectively demonstrate a trajectory toward practical, deployable solutions in vegetable production. Vijayakumar's growing body of work signals a researcher whose influence on precision agriculture and sustainable farming technologies is poised to expand significantly in coming years.
