    • 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 height  0.6m, are 0.273ha/hr, 0.158ha/hr and 57.81% and  at spraying height 0.7m are 0.269ha/hr, 0.15 ...

      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 sprayer with long boom, long lances or spray gun are used to carry fluid at different targets.  In t ...

      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 flows by gravity to a vibrating or oscillating nozzle which produces a coarse fine shape pattern. T ... Continue Reading

         

      CHAPTER THREE - [ Total Page(s): 5 ]CHAPTER FOUR4.0    Performance evaluation of the Single wheel driven boom spryer4.1       Experimental procedure    An area of land was selected for carrying out the performance evaluation of the sprayer, the area of land was beside the automotive workshop in the Institute of Technology, Kwara state polytechnic. The area measured 20m by 6m which was divided into three subplots. The tank of the sprayer was filled with water and then pulled to start spraying from the beginning to the end of the plot.  A stop watch was used to know the time taken for spraying and spaying was carried ...
