Abstract


Fractionating the irrigation blade over the course of a day can improve water efficiency, extending the time of water availability in the soil and obtaining better use by the plants. This work evaluates the effects of the pulsed drip irrigation system on pepper yield compared to the continuous drip system. The agronomic characteristics of the fruits, productivity and water use efficiency were measured in the context of drip irrigation in an experimental test in randomized blocks. Analysis of variance and averages test were assigned for data validation, principal component analysis and dendrogram graph were used to analyze the trend and similarity of the data, generated by the RStudio ® software. The fractionated irrigation blade in 4 applications performed better than the other fractionations, in terms of productivity and water use efficiency. In pulse 4, the diameter, height and thickness of the fruit wall obtained results that did not differ from the effects of pulse 5. Plants irrigated by pulse 4 produced more fruit, characterizing higher yield. It was demonstrated that the fractionation of the irrigation blade in 4 applications significantly increased the productivity and the efficiency of water use in the pepper culture.
