| description | Irrigation and fertilizer are two essential factors affecting rice root traits and yield. In this respect, a pot experiment was performed at the <i>boro</i> (dry season irrigated) season of 2021–2022 in the Department of Agronomy of Bangladesh Agricultural University, Mymensingh, Bangladesh. The variety Binadhan-10 was planted at two irrigation conditions, i.e., saturation (S) and continuous flooding (CF); two potassium (K) doses, e.g., 65 kg ha<sup>−1</sup> (K<sub>65</sub>) and 98 kg ha<sup>−1</sup> (K<sub>98</sub>); and two nitrogen (N) doses, i.e., 140 kg ha<sup>−1</sup> (N<sub>140</sub>) and 210 kg ha<sup>−1</sup> (N<sub>210</sub>). The experiment was laid in a split plot design with eight treatments and replicated thrice. The findings confirmed the significant variation in irrigation, K and N and the effects on root number (RN), root length (RL), root volume (RV), leaf area index (LAI), total dry matter (TDM), yield attributes and yield. Considering the interaction among irrigation, K and N, the S conditions with K<sub>65</sub> and N<sub>140</sub> showed best performance in relation to root parameters. At 80 DAT, the highest RN (373.00), RL (1700.00 cm), RV (8.90 cm<sup>3</sup> hill<sup>−1</sup>), LAI (4.94) and TDM (25.83 g plant<sup>−1</sup>) was obtained from this combination. Grain yield (GY) and root traits, except root porosity, showed a significant positive association. Grain yield (GY) was the highest (27.12 g pot<sup>−1</sup>) under S conditions with K<sub>65</sub> and N<sub>140.</sub> Therefore, the variety Binadhan-10 can be successfully cultivated with K<sub>65</sub> and N<sub>140</sub> under S conditions. |
