Impact Des Différents Systèmes De Cultures Sur La Culture De Blé Tendre (triticum Aestivum, L), Var. Hd 1220 En Conditions Semi-aride

The experiment was carried out on a long-term experimental site of the ITGC station of Sétif during the 2009/2010 campaign. The objective is to study the effect of cropping systems, direct seeding (SD), simplified cropping techniques (TCS) and conventional (TC) and previous (wheat, oats, lentils) on crop behavior and See the medium-long-term impacts on soil physicochemical properties. Several variables related to culture were studied and analyzed statistically. The results obtained revealed an effect of culture and previous cropping on yield and its components.
