Abstract

The present work was carried out to study the effect of land lev­eling by laser technique, leveling slope ( 0.03%, 0.05% ) and strip length on water application efficiency and the performance of chisel plough and seed-drill. The field experiments were conducted at Sids Agricultural Re­search Station in clay soil, planting (Sids -1) wheat variety_ Using Nord­sten seed drill, Dainish make and a local manufactured chisel plough. The results indicated that, the highest water use efficiency and yield were obtained when field plot length was of 150 m and slop 0.05 % while the lowest water use efficiency and yield were obtained at zero level and plot length of 150 m. The operating tractor slip and actual field capacity were not affected by slope % but were affected by plot length. The av­erage tractor forward speed increased by 19 %and 4% for chisel plough and seed drill respectively when the plot length increased from 50 m to 150m. Also the tractor fuel consumption was not affected by surface slope but were affected by plot length The tractor fuel consumption litl h. increased by 4% and 19% when using chisel plough and seed drill re­spectively when the strip length increased from 50m to 150m. Field ca­pacity increased by 38 % and 27 °A, for chisel plough and seed drill re­spectively when the plot length increased from 50 m to 150m.
