Table 7

Regression equations between irrigation frequency and amount and tomato yield and water use efficiency.

	Dependent variable	Regression equation		Combination of treatment for max
				Spring	Comprehensive score		0.99	5	0.8	173.30
Yield (kg/hm^2)		0.93	4		1.1	119464.90
WUE (kg/m^3)		0.89	5		0.8	33.70
Autumn	Comprehensive score		0.99	5	0.9	153.93
	Yield (kg/hm^2)		0.99	4	1.1	99181.15
	WUE (kg/m^3)		0.98	5	0.8	39.43

Note: is the irrigation frequency and is the irrigation amount, respectively.
