Preliminary Investigation on Crop Growth, Physiology, and Yield of Rice under Partial Root-Zone Irrigation

Table 1

Rainfall and total water supply (irrigation plus rainfall) of PMK (R) 3 rice by split root experiment.

Irrigation treatments	Irrigated water (mm)	Rainfall (mm)	Total water applied (mm)	Water saving relative to control (mm)
PRI1	356	81	437	249
PRI2	274	81	355	331
PRI3	229	81	310	376
PRI4	209	81	290	396
PRI5	189	81	270	416
PRI6	176	81	257	429
Control	605	81	686	0
Mean	291	81	372	—

Increment in water saving is expressed at different partial root-zone irrigation treatments over the conventional irrigation.
