Abstract

The relationship between rice root morphology and Potassium (K) is a major concern for its growth and development, and it has a substantial impact on yield as well. In light of this, the current pot research was run in the net house of the Department of Agronomy at the Bangladesh Agricultural University, Mymensingh, Bangladesh, throughout the boro (dry season irrigated) season of 2020–2021. Binadhan-10, Hira-2 and BRRI dhan29 were grown with five K fertilizers: 0 kg K ha−1 (K0), 32 kg K ha−1 (K32), 65 kg K ha−1 (K65), 98 kg K ha−1 (K98) and 130 kg K ha−1 (K130). Three replications of the investigation were conducted using a completely randomized design (CRD). The root number (RN), root length (RL), root volume (RV), root porosity (RP) along with leaf area index (LAI), total dry matter (TDM) and yield were assessed. Binadhan-10 with the K65 treatment significantly increased the RN, RL, RV, LAI, TDM and yield. With the further increase in the dosage of K that was under K98 and K130, the value of the root traits and yield did not increase. A positive connection was documented between the grain yield (GY) and all the root traits, excluding the RP. Binadhan-10 can be grown with 65 kg K ha−1 at field level for a satisfactory yield.
