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% respective
