Abstract
Some experiments were carried out in two locations to determine the energy consumption of wide varieties of sprayers. Firstly, at the Experimental Station of the Faculty of
Agriculture, Ain Shams University at Shalaqan ” شلقان”, Kalubia
Governorate. Secondly, at the Agricultural Mechanization Training Center, Ministry of Agriculture, El-Maamoura ” ” المعمورة, Alexandria Governorate.
Ground spraying equipment (knapsack-hand-operated, knapsack-air-carrier, mounted-blower, mounted-boom and BLITZ.SSB hand-held battery) and aerial application (fixed and rotary wing planes) were evaluated by making comparative study to evaluate energy requirements and economical feasibility for computer modeling based on unit time and unit area.
A computer program was made for spraying machinery to select the optimum spraying equipment depending on several pomts regarding energy and management of these equipment via input required data in the program.
Important results of this investigation can be summarized as follows:
1- Fuel consumption rate (L/hp.h) was recorded for all spraying equipment. The observed data indicated that fuel consumption rate of knapsack-air-carrier (0.325 L/hp.h) was less than that observed for both mounted-boom (0.54 L/hp.h) and mounted-blower (0.68 L/hp.h) by 62.2 and 60.2% respectively as ground spraying.
