Cultivo do pimentão amarelo com águas energizada e não energizada e com doses de biofertilizante - DOI: 10.7127/rbai.v8n400183

This study was aimed at evaluating the production characteristics of the yellow Sunny F1 hybrid pepper irrigated with energized and not energized water and with water with different doses of biofertilizers. The experiment was conducted from August 2010 to December 2010 in the experimental area of the weather station belonging to the Universidad Federal do Ceara (UFC) in Fortaleza, Ceara (Br). The experimental design was one of randomized blocks with four replications, set up as split plots, with plots  irrigated with differently treated water (energized and not energized) and the subplots  irrigated with water containing different dosages of  biofertilizer (0, 400, 800, 1200 and 1600 L ha -1 week -1 ), where the median dosage (800 L ha -1 week -1 ) is the dosage  applied by chili producers of the Serra da Ibiapaba by regional technical norm. The experiment was conducted in pots with 40L capacity, with four plants per treatment. We evaluated the following production characteristics: soluble solids (SS), length, diameter, average fruit weight (PMF), flesh thickness (EP), number of fruits and total yield. Based on the results and on the conditions under which the study was performed, we concluded that: The energizing water treatment did not cause significant changes to the cultivation of peppers under ideal irrigation conditions; The readings of soluble solids (SS) and fruit length, as functions of the biofertilizer dosage, applied to a cubic polynomial regression model, were significant; The biofertilizer was not enough to adequately fertilize the crop, even in the larger dosages applied, demanding supplementation with mineral fertilizer or dosage increase
