Abstract
- The research was conducted from April to September 2016, at the Fabio Baudrit Moreno Agricultural Experimental Station of the University of Costa Rica, Alajuela, Costa Rica, with the Costa Rican hybrid of sweet pepper ‘Dulcitico’, in hydroponic system under greenhouse. The effect of 2 planting densities (1.4 and 2.4 plants.m-2) and 3 volumes of substrate (7, 14 and 21 L.plant-1) on the yield, total available water content (ATD) in the substrate, drainage, crop evapotranspiration (ETc) and water use efficiency (EUA) were evaluated. A design of 3 complete blocks at random with a factorial arrangement of 2 x 3 treatments was used. The ETc was obtained by water balance in the substrate and the EUA as a result of the ratio between yield and ETc. For all the response variables, no different trends were observed between the two planting densities, as the substrate volume was increased from 7 to 21 L (p
