Abstract:

A field experiment was carried out during the kharif season of 2025 at the Agriculture Research Farm at Himalayan University, Jollang, Itanagar, to examine the Influence of Plant Bio – Regulators on the Growth of Khamti Lahi Rice (Oryza Sativa L.). The experiment was laid out in a Randomized Block Design (RBD) with three replications and nine treatments, viz., T1-Control, T2- Seaweed extract-0.5 ml, T3- Seaweed extract-0.5 ml + 1.5% Urea, T4-Jeevamrut-100 ml, T5- Jeevamrut-100 ml + 1.5% Urea, T6- Thiourea-500 ppm, T7- Thiourae-1000 ppm, T8- Gibberellic acid-100 ppm, T9- Gibberellic acid-100 ppm + 1.5% Urea. The observation recorded at 30, 60, and 90 days after transplanting (DAT) showed significant differences among treatments in term of plant height, leaf length, number of tillers, leaf width, dry matter accumulation, and yield attributes. The results revealed that treatments T8 (Gibberellic acid-100 ppm) was found to be the most effective in enhancing growth and yield parameters, followed by its combined application with urea T9 (Gibberellic acid -100 ppm +1.5% Urea). In contrast, the control treatment T1 consistently recorded the lowest value, which did not receive any growth regulators, or nutrient supplementation. The findings of the study indicate that the application of plant bio-regulators, particularly gibberllic acid, either alone or in combination with urea significantly improves growth, yield and nutrient uptake of khamti lahi rice under the agro-climatic conditions of Arunachal Pradesh.
