Abstract
Our experiment is mainly based on the comparison of two methods of tillage leading of cereal cultivation under pivot in the arid zone, a case of El Meniâa (wilaya of Ghardaia). To achieve this, we have tested the technique of direct sowing in the Saharan zone by applying a random block experimental device with two treatments, T1 and T2, representing, respectively, a direct sowing and a sowing preceded by soil tillage by means of a double passage of the tine cultivator. The results show that the obtained yields reveal no significant difference between the two treatments, which means that the leading of cereal cultivation under pivot can do without a prior tillage.
