Method to evaluate the efficiency of manual overhead irrigation in citrus rootstock liner production REA
SALVADOR,CONAN A.; FERRAREZI,RHUANITO S.; BARRETO,CARLOS V. G.; TESTEZLAF,ROBERTO.
ABSTRACT Brazil produces grafted citrus seedlings in closed screen houses to reduce pest and disease incidence. Irrigation is usually performed by hand using either breaker nozzles or drilled polyvinyl chloride (PVC) pipe wands on garden hoses. Rootstocks are produced in cone-shaped containers filled with soilless potting mix. Since the containers have a small upper diameter, nutrient solution capture is reduced with the potential to cause environmental contamination from inefficient fertigation. This study provides a method to assess the efficiency of manual overhead irrigation systems used in liner production. The method consists of determining both the volume of water applied and volume lost (i.e., directly and by percolation) in order to obtain an...
