Ramon Cabanos Barba ONS (August 31, 1939 – October 10, 2021) was a Filipino inventor and horticulturist[1][2] best known for inventing a way to induce more flowers in mango trees using ethrel and potassium nitrate.

"[8] Barba received a scholarship from the University of Georgia where he began conducting experiments on inducing the flowering of plants using gibberellic acid and potassium nitrate as a fertilizer.

[1][2] Barba then took up a PhD course in plant physiology, specializing in Tropical Fruits and Tissue Culture from the East-West Center of the University of Hawaii at Manoa, graduating in 1967.

[11] His study, titled Induction of Flowering of the Mango by Chemical Spray was named best paper by the Crop Science Society of the Philippines (CSSP) in 1974.

[2] In an interview released by the World Intellectual Property Organization in 2011, Barba recounts that he did not initially file a patent for his method, wanting farmers to be able to use the technique freely.
