Water and Radiation Use Efficiencies of Pepper (Capsicum annuum L. cv. Carliston)
Journal Title: Scholars Journal of Agriculture and Veterinary Sciences - Year 2015, Vol 2, Issue 2
Abstract
Abstract: This study assessed the effect of different irrigation regimes for pepper plants (Capsicum annuum L. cv. Carliston) on vegetative growth, the intercepted photosynthetically active radiation (IPAR), water use efficiency (WUE), radiation use efficiency (RUE) for yield and total dry matter (TDM). The incoming amount of PAR was 1424.7 MJ m-2, of which 285.2 Mj m-2 intercepted in the I0.2, 336.3 Mj m-2 intercepted in the I0.5, 352.8 Mj m-2 intercepted in the I0.8, 446.8 Mj m-2 intercepted in the I1.0, 407.2 Mj m-2 intercepted in the I1.2 treatments. The highest yields as 20.6 Mg ha-1 and 21.57 Mg ha-1 were obtained from the I1.0 and I0.8 in which the applied water was 646 mm and 518 mm, respectively. Being a strong relation between IPAR and applied water (I) and evapotranspiration (ET), IPAR is thought to be used to activate the irrigation system automatically. Keywords: Pepper (Capsicum annuum L. cv. Carliston), solar radiation, PAR, drip, irrigation
