Development, Fabrication and Performance Evaluation of a Single Wheel Driven Boom Sprayer

ABSTRACT

The single wheel driven boom sprayer was developed, fabricated and evaluated for its performance at the department of Agricultural and Bio-environmental engineering workshop, Kwara state polytechnic, Ilorin. The spraying performance was carried out at spraying height of 0.5m, 0.6m and 0.7m respectively. The theoretical  field capacity CT, the effective field capacity CE and  Field efficiency (ŋ) at spraying height of 0.5m  are 0.285ha/hr , 0.165ha/hr and 58%, while at spraying height  0.6m, are 0.273ha/hr, 0.158ha/hr and 57.81% and  at spraying height 0.7m are 0.269ha/hr, 0.155ha/hr and  58.055%  respectively.                                                                                                                                                                                  TABLE OF CONTENTS
