Field Crops in Facing Future Challenges
Abstract: The comparative study of direct and conventional sowing conducted during two years in semiarid zone of Tunisia showed a difference in behavior of the durum wheat crop and in five tested varieties (Karim, Khiar, Om Rabia, Razzak and Nasr). In the first year of crop management, the conventional mode expressed the highest yield compared to direct sowing (28.8 and 19.7 quintals / ha * respectively). After the second year, the practice of direct sowing has given yields that approximate the conventional sowing (11.9 and 12.1 quintals / ha respectively). It should be noted that during the second year the yield was low due to marked drought conditions.
Data analysis of two trial years also showed the potential production of Om Rabia and Khiar varieties in direct sowing (18.2 and 17 quintals / ha respectively). These two varieties seem to have a satisfactory performance at direct seeding for two years.
Under this work, the mean protein content in both years of study is not affected by cultivation method with 13.58 and 13.40% / DM for conventional and direct sowing, respectively. It should be noted that in direct sowing, Khiar variety was distinguished by a fairly good protein content compared to the conventional method (14.46 vs. 13.34% / MS, respectively). The extraction results of gluten show that the rate of all varieties in both years of essay showed a slight difference in favor of the conventional method compared to direct seeding with 16.5 and 15.94% respectively. For this parameter, the varieties Om Rabia, Nasr, Karim and Khiar have a balanced gluten reflecting good technological value and suitable to make pasta or couscous.
