HyderabadPaclobutrazol raised rice culm strength from 0.39 to 0.60.
Plant height fell up to 9.8% at the recommended nitrogen dose, without affecting grain yield.
The Institute of Rice Research tested 4 paclobutrazol doses at 2 nitrogen levels in the 2022 Kharif season.
The strongest culms came at 90 grams of active ingredient per hectare.
The paper is an accepted preprint that the final version will replace.
