Abstract

The objective of the research was to evaluate the uniformity of drip irrigation with photovoltaic pumping with and without storage in batteries. using normal and self-compensating emitters. The experiment was conducted at the Federal University of Viçosa. Minas Gerais. Brazil. Two drip irrigation systems were tested. one with self-compensating emitters and the other with normal emitters with a flow rate of 4 L h-1. The coefficients of uniformity of Cristiansen and distribution (CUC and CUD) were used to evaluate the performance of the irrigation systems. The volumes pumped by the autonomous system and stored in batteries throughout the year in all regions of the country were compared for the period from 02/01/2018 to 01/31/2019. a period that contemplates the data collection phase of the experiment. According to the results. the uniformity of the drip systems with and without energy storage. with emitters normal and self-compensating presented a coefficient between 93% and 97%. classified as excellent. The largest volumes pumped throughout the year for drip irrigation systems with normal and self-compensating emitters without batteries occurred in the Northeast region of Brazil.
