The experiment was conducted during three growing seasons and two planting dates. The objective of the study is the analysis of phenotypic variability of traits measured for 15 varieties of durum wheat, through the average effects, to decline the ways, characters and varieties could play in favour of performance under the constraining semi-arid conditions. The year effect indicates that given the difficulty of predicting the performance enabled by years, it then makes sense to go straight for this performance within genotypes. Analysis of the effect genotype highlights characters connected to performance and is the Setifis variety that lends itself well. For the effect of sowing date, it is that early sowing promotes a better expression of the characteristics compared to late sowing.

Carbon Sequestration by Direct Seeding of Wheat in Setif High Plains (North East Of Algeria)

Progress in Clean Energy, Volume 1 pp Cite as. Direct seeding is an important element of conservation agriculture; it contributes to environmental conservation and to sustainable agricultural production. Conservation agriculture increases carbon concentrations in the topsoil. It can also reduce the amount of fossil fuel consumed in intensive tillage and by other farm operations, and thus decrease the rate of CO 2 build-up in the atmosphere. Today, the global area of no-till farming is more than million hectares.
