The purpose of this investigation was to study the effect of rotary plow on the soil physical properties and barely production under Libyan rainfall conditions. Four different plowing depths (5, 10, 13 and 16 cm) were applied with four different forward speeds (3.5, 4.5, 5.5 and 6.5 km.h-1) at each plowing depth. The field experiments were carried out in a sandy-loam soil. The planting method was manual broadcasting and no other treatments were applied after barley seeds broadcasting. The irrigation was completely dependant upon the amount of rainfall during the experiments period. The obtained results from this investigation could be summarized as follows: The soil bulk density and the penetration resistance were much more decreased after all seed-bed preparation treatments, especially in the upper layers of the plowed soil (0-5 and 0-10 cm), since they were decreased from 1.126 g.cm-3 and 38.86 N.cm-2 to 0.832 g.cm-3 and 23.36 N.cm-2, respectively. The soil porosity and voids ratio showed reverse trends as compared with the changes in the soil bulk density. Using the rotary plow for 10-cm depth with 4.5 forward speed gave the higher values of actual field capacity (0.338 fed.h-1), higher field efficiency (83.66%), little fuel consumption (17.22 L.fed-1) and required the lowest values of energy (14.48 kWh.fed-1) as compared with the deeper plowing depths (13 and 16 cm) at the same forward speed. On the other hand, the obtained results at 10-cm plowing depth were almost closely to those obtained at 5-cm plowing depth. The plowing depth showed a significant effect on the number of plants per feddan (plant. fed.-1), weight of 1000 seeds (g.) and the biological yield per feddan (grains and straw) than the effect of the forward speed.
