Field experiments were carried out at EI-Gemmiza Research station EI-Garbla Governorate to study the effect of some different levelling methods (Traditional and LASER) and planting methods (seed drill. mechanical planter and pneumatic planter) on soybean yield. Also. the effect of levelling method on performance and characteristics of planting machine was considered.
The results revealed that, when the LASER levelling was used instead of the traditional land levelling. The planting method by pneumatic planter at forward speed 3.15 kmlh gave maximum values of germination ratio (92.27 %), unUormity (94.47%) and total yield (1.45 Mg/ fed). For all the used treatments, the planting forward speed increase tends to decrease genmination ratio, uniformity and total yield of soybean crop. The yield case of LASER levelling and pneumatic planting method was maximum in comparison with other methods.
