Optimum Nitrogen Application Acclimatizes Root Morpho-Physiological Traits and Yield Potential in Rice under Subtropical Conditions.

ABSTRACT: Nitrogen (N) is a highly essential macronutrient for plant root growth and grain yield (GY). To assess the relationship among N, root traits, and the yield of boro (dry season irrigated) rice, a pot experiment was performed in the Department of Agronomy, Bangladesh Agricultural University, Mymensingh, Bangladesh, during the boro rice season of 2020-2021. Three boro rice varieties, namely BRRI dhan29, Hira-2, and Binadhan-10, were planted at four N doses: 0 kg ha^-1 (N₀), 70 kg ha^-1 (N₇₀), 140 kg ha^-1 (N₁₄₀), and 210 kg ha^-1 (N₂₁₀). The experiment was conducted following a completely randomized design with three replicates. The varieties were evaluated for root number (RN), root lengt
