Table 1 Water and soil data for both cultivars under two different irrigation treatments

	C. annuum 'Chili-AS Rot'		C. chinense 'Naga Morich'
	Field capacity	Deficit irrigation	Field capacity	Deficit irrigation
Added water (mm)	302.6 ± 0.7^a	185.0 ± 0.3^b	248.4 ± 0.5^a	166.4 ± 0.2^b
Average soil water content (%)	36.7 ± 1.3^a	14.1 ± 0.7^b	36.2 ± 1.7^a	12.8 ± 1.1^b
Average soil water tension (kPa)	− 12.6 ± 0.2^a	− 51.2 ± 0.6^b	− 12.0 ± 0.3^a	− 54.0 ± 0.9^b

Data with different lower-case letters (a, b) are significantly different (multi-way ANOVA; Duncan test)
Data are means ± standard error (n = 5)
