| Abstract | ||||
| In Egypt, it could be not able to test the vertical distribution for agriculture sprayer machines this may be due to the poor measuring instruments such as vertical patternator. The aim of the current research is develop and evaluate an inexpensive vertical patternator for hydraulic sprayers. The study carried out in laboratory of agricultural engineering dept., faculty of agriculture, kafr El-Sheikh University. The vertical patternator manufactured from the local material under laboratory and work station in kafr El Sheikh University. The tests and the evaluation of the patternator included two main parameters. The first treatment was evaluation the three vertical sprayers under laboratory conditions. As well as, the second treatment was evaluation two different measured methods to determine the efficiency of the sprayer by using the CV %. The results indicated that, the Tee-jet XR 110-3 VP nozzles gave the highest percentage value of spray liquid captured compared to Hardi110-02 LS and LU110-04 nozzles. The development patternator captured more spray liquid due to increase of the operating pressure of spray liquid. The t-test value for LU 110-04 nozzle was -1.48 with standard error (SE) 0.23 and probability P-value 0.89. It could be used the automatic method to estimate the CV % and it's easy to apply. As well as, there are no different effect between manual and automatic method at the volume application rate 200 l/fadd., 400 l/fadd. and 500 l/fadd for the CV %. | ||||
