The aims of this investigation were to analyze pea crop yield and quality under different sprinkler atomization theories; estimate the crop reduction coefficient due to the examination point of view along sprinkler lateral lines and determine the energy requirements for seedbed preparation under newly reclaimed areas of Egypt. Therefore, two field experiments were carried out during two successful growing seasons (2006 and 2007) in the Desert Experimental Farm of Faculty of Agriculture, AinShamsUniversity at El-Bustan region, which represents sandy soil conditions in the western desert of Egypt.
                Results revealed that rotating sprinkler had the highest vegetation growth factors "plant height and number of pods per plant" followed by small and large nozzles impact sprinkler respectively. However the vegetation growth factors: plant height and number of pods per plant had been increased with about 19and 23% with rotating sprinkler and about 13.7and 6.8% with small nozzle impact comparing with large nozzle impact sprinkler. With respect to the effect of the point of estimation along sprinkler lateral line, data revealed a non-homogeneity trend due to the effect of sprinkler atomization theories and corresponding nozzle sizes. However, data revealed that there is heterogeneity of the highest values with regard to the examination point along sprinkler lateral line under different sprinkler atomization theories.
