| Summary: | Adopting sustainable agricultural practices is considered as an effective strategy to mitigate climate change and to improve soil health and crop production.This study aims to assess the impact of tillage systems (no-tillage (NT) and conventional tillage (CT)), crop rotation (faba beans - oat and faba beans - durum wheat) and nitrogen fertilization rates (0, 20 and 40 kg N.ha ^−1 ) on soil properties and growth and yield of fenugreek. Soil samples were collected at two stages: at the 50% blossoming stage and after harvest and fenugreek quality and yield and its components were measured.The results showed that tillage systems and crop rotation treatments had great influence on soil properties. In general, the highest soil organic carbon (SOC) (13.4 and 14.2 g.kg ^−1 ), total nitrogen (1.0 and 1.1 g.kg ^−1 ), nitric nitrogen (75.73 and 62.42 mg.kg ^−1 ), ammonium-nitrogen (14.90 and 19.08 mg.kg ^−1 ). were recorded in no tillage practice with durum as a previous crop at 50% blossoming and harvest stage respectively. Exception for SOC, the highest nitrogen fertilization rate improved most of soil variables at both growth stages. Greater biomass and grain protein content were obtained under NT system and 40 kg N.ha ^−1 . Previous crops had no effect on grain protein content. Also, there was a significant synergy among soil fertility and fenugreek production. Conservation tillage, durum wheat previous crop and highest nitrogen fertilization rate gave the best aboveground biomass, yield and yield attributes performances. Overall, NT associated with durum wheat as a previous crop and nitrogen fertilization (40 kg N.ha ^−1 ) are the suitable combination to improve both soil quality, and fenugreek yield. |
