Installation of the alternative sprayer irrigation system with pet bottles on an earth site at the fazenda escola de São Luís/Ma

Abstract

Commercial irrigation in Brazil is admittedly costly, an obstacle that restricts its use by most family farmers. Alternative irrigation systems emerge as a sign of the independence of small producers in relation to equipment and imported systems, giving them a viable option to maintain and increase their production, improving their income. The management of a crop's irrigation must be based on criteria that allow the application of water to the soil and promote optimal production, from an economic point of view. This work aimed to develop an alternative irrigation system, aimed at family production, demonstrate the functioning of the system and determine the flow rate of the alternative irrigation system. The study area of the alternative system was set up on the campus of the State University of Maranhão – Campos São Luís (UEMA), in a 0.90 m x 15 m construction site in the experimental area of Fazed Escola de São Luís/FESL. It is a simple system, made from the use of pet bottles, filled with water,producing irrigation in the form of rain. To keep the material suspended, a wooden picket can be used. To make the sprinkler, holes were made in the pet's bottles, using a hot sewing needle, hoses, and water glue. To calculate the sprinkler flow rate, the simple flow formula was used. The assembled system showed good efficiency, without wasting water or causing erosion in the bed, in addition to irrigating the planted area. With a flow rate of 0.00063 L s found. Therefore, we recommend this system for small producers.
