Résumé : | Our study aims to simulate scenarios depending on the type of soil (low and high water retention capacity WHC), the type of rotation (2/3 years), and different management amounts (fertilization and irrigation) in the crop growth model CropSyst , in order to increase yield, efficiency in nitrogen and water use and net profit. It appears from the results obtained that the wheat-potato rotation for the 2-year rotation and wheat-fallow-potato for the 3-year rotation are the most productive even with low efficiency in the use of resources (Nitrogen and water). Moreover, the wheat-fava bean rotation scenario seems to be a better substitute for the wheat-wheat rotation in terms of protein production. For a soil with a low water retention capacity WHC, the protein production is 1.1 t / ha and 0.9 t / ha respectively for the wheat-bean and wheat-wheat rotations. For a soil with high retention capacity, the protein production is 1.4 t / ha for wheat- fava bean against 1.8 t / ha for wheat-wheat. In addition, this wheat-fava bean cropping system could generate a higher net profit than the wheat-wheat one. Finally, the wheat-potato rotation can generate very high net benefits but with low input efficiency. On the other hand, in terms of wheat grain yield and protein production, the wheat-fallow rotation is the least productive rotation, and it has low net profit. For 3-year rotations, there is no significant difference between the different rotations regardless of the type of soil and management. wheat-fallow-bean rotations produce the highest amounts of protein, which range between 0.9 and 1.7 t / rotation / ha, followed by the wheat-fallow-potato, which range between 0.6 and 1.5 t / rotation / ha. The wheat-fallow-potato rotations in the different managements produce the lowest amount of protein, which is between 0.5 and 1.3 t / rotation / ha. However, the three rotations types show the same profitability in soil with low WHC but with a higher net benefit profitable in soil with high WHC. |
