Crescimento de pimenteiras biquinho (Capsicum chinense) em substratos orgânicos sob diferentes lâminas e qualidades de água.

Abstract

The reuse of water to irrigate different crops has become an alternative for regions with scarce water, as well as to reduce costs and quality water input. It was conducted in greenhouse belonging, from April 12 to October 6, 2015, the Universidade Federal of Campina Grande, two independent experiments, aiming to evaluate the performance of organic ornamental pepper (Capsicum chinense) under different irrigation with water supply and wastewater treated in dissimilar substrates. Every experiment was carried out with different organic substrates (cattle and goats). The treatments consisted of five laminas irrigation(L) using water supply and wastewater from the anaerobic reactor upstream (UASB+ WETLAND) based on the water requirement (NH) culture, being them: 100% NH (L5), 80% NH (L4), 60% NH (L3), 40% NH (L2) and 20% NH (L1). Evaluated were the composition of growth and evolution, floral initiation, fitomassas and water use efficiency of pepper. The various water blades applied were statistically significant for all growth variables. For germination with bovine substrate considered the ideal blade is 20% and 80% NH, while for the pepper plants cultured in goat substrate is 20% NH. For proper development irrigation depth of 80 to 100% is enough to meet the water demand of pepper. The pepper showed higher accumulation of biomass with the application of blades from 60% of the water requirement of the plant. According to the results, noted the importance of irrigation management aimed directly at the efficiency of water use.
