4.3 Results and discussions
The results of the performance evaluation of the sprayer as shown on table 4 at spraying height of 0.5m, 0.6m and 0.7m and average speed of 3.03km/hr, 2,927km/hr and 3.169km/hr.The corresponding time spent during spraying operation were 22.7sec, 23.70sec and 22.24sec, also the field efficiency were 58%, 57.81% and 58.05% respectively.
The results obtained shows that the field efficiency increases as the spraying height is increased, and this also indicate the fact that less spraying time was observed for higher boom spray height than lower boom spray height. And also, the theoretical field capacity appeared to increase as the boom spray height is increased but the lower field efficiency observed at spray of 0.6m probably indicates that higher time of spraying operation observed could be responsible for the higher theoretical field capacity and as well as the lower field efficiency observed at the spray height of 0.6m.

ABSRACT - [ Total Page(s): 1 ]ABSTRACTThe 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 (Å‹) at spraying height of 0.5m are 0.285ha/hr , 0.165ha/hr and 58%, while at spraying hei ...

CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONE1.0   IntroductionCrop yield is reduced by mainly due to attack of pest, diseases and weeds. Chemical control is the popular method adopted for controlling most insects, weed and diseases. The chemical are applied either by spraying or dusting. Spraying is one of the most effective and efficient techniques for applying small volume of spray liquid to protect crops. In conventional methods, manually operated low and high volume hydraulic sprayer and power operated hydraulic s ...

CHAPTER TWO - [ Total Page(s): 9 ]   Centrifugal energy sprayers: In the centrifugal energy sprayer the spray fluid is fed under low pressure at the center of a high speed rotating device such as flat, concave or convex disc. Spray is atomized by centrifugal force as it leaves the periphery of the atomizer. The droplets are carried by the air stream generated by the blower of the sprayer or by prevailing wind, if the sprayer is not provided with a fan.Kinetic energy sprayers: In kinetic energy sprayer the spray fluid ...
