Abstract: A micro-plot experiment in the field was conducted in four typical indica rice varieties (lines), selected from 256 ones, with different of potassium efficiencies of utilization. The micro-plot was consisted of a PVP tube with both width and height of 30 cm, i.e. 7.07×10-2 m2. The tube was inserted

Key words: Indica rice, Efficiencies of K utilization, Micro-plot trial, Dynamic changes
