It is of great significance to study the root characteristics of rice to improve water and nitrogen(N) use efficiency and reduce environmental pollution. This study investigated whether root traits and architecture of rice influence grain yield, as well as water and N utilization efficiency. An experiment was conducted using the upland rice cultivar Zhonghan 3(a japonica cultivar) and paddy rice cultivar Huaidao 5(also a japonica cultivar) using three N levels, namely, 2 g urea/pot(low amount, L...
