Computer Programming for Selection of Boom Width and Tank Capacity of Field Sprayers

Abstract

A computer programme was developed for selection of
boom width and tank capacity of field sprayer. The computer model
was built up using Visual Basic (ver.6) computer programming
language in which input data were inserted directly and output results
were obtained easily on the computer screen or as a printout. The
model was verified with data collected from some agricultural private
companies in Gedarif area, Kenana agricultural implements factory
and some data from the literature. The validity of the model was tested,
and the results showed close agreement between the field
measurements and the computer model predictions. The sensitivity
analysis of the model revealed that changes in any of the input
parameters used could directly affect the output of the model, such as
boom width, tank capacity and work rate. The accuracy of the model
was also tested statistically. The model is helpful in proper sprayers
management and quick decision-making.
