- Abstract
Two separated field experiments were carried out during the two successive winter growing seasons of 2011/12 and 2012/13 at the farms of Directorate of Agriculture, EI-Kharga, New Valley governorate, Egypt. The first one was carried on sweet pepper (cv. California Wonder); meanwhile the second one was carried Qn hot pepper (cv. Anahiem). The aim of this study was to investigate the effect of irrigation regimes (1800, 2300 and 2800 m³ fed-1) under two irrigation systems (modified surface and drip irrigation systems) on growth, yield and irrigation water use efficiency (IWUE) of the aforementioned two pepper cultivars. The results showed that, the highest values of fruits yield were obtained from plants irrigated with 2300 m³ fed-1 under drip irrigation. This held true for studied pepper varieties. The highest values of IWUE were achieved by plants irrigated with 1800 and 2300 m³ fed-1 under drip irrigation for the two pepper cultivars. It could be extrapolated that using irrigation water at a rate 2255.4 and 2673.60 m³ fed-1 produced a maximum of 4688.46 and 4267.34 kg fed-1 fruits yield of California Wonder cultivar; while using 2297.44 and 2625.40 m³ fed-1 irrigation water gave 4682.15 and 4322.81 kg fruits yield fed-1 for Anahiem cultivar under drip and modified surface irrigation, respectively.
