Water Stress Induced Changes in Root Traits and Yield of Irrigated Rice under Subtropical Condition

The presence of water or the degree soil saturation has a direct impact on root development and function in rice. In this regard, pot investigation was performed to test response traits yield components boro (irrigated) Three rice varieties named Binadhan-10, Hira-2 BRRI dhan 29 were grown at four irrigation regimes, viz. continuous flooding (CF), (S), 75% S 50% Bangladesh Agricultural University, Mymensingh, Bangladesh, throughout period 2020–2021. study replicated three times by employing completely randomized design (CRD) method. revealed drastic decline attributes S. A significant increase number (RN), length (RL), volume (RV), total dry matter (TDM) grain (GY) under condition followed CF observed. Binadhan-10 exhibited largest scores RN (359.00), RL (1577.83 cm) RV (8.34 cm3 hill−1) 80 DAT condition. Root GY found be substantially positively associated all observations. best with regard seed output (26.13 g pot−1) increased CF, 4.06%, 23.72% 46.00%, respectively.
