Improvement of Maize Productivity and N Use Efficiency in a No-Tillage Irrigated Farming System: Effect of Cropping Sequence and Fertilization Management.

The sequence of the preceding crops in a no-tillage farming system, could interact with the integrated use of mineral and organic nitrogen (N) sources in a way that improves the growth and productivity of the terminal maize crop, meanwhile, enhancing its N use efficiency (NUE). In the current study, six legume-cereal crop sequences, including faba bean, soybean, Egyptian clover, wheat, and maize were evaluated along two experimental rotations that ended up by planting the terminal maize crop. In addition, the effects of applying variable mineral nitrogen (MN) rates with and without the incorporation of farmyard manure (FYM) on the productive performance of maize and its NUE were tested.

Agronomic and qualitative characterization of multi-cut berseem clover (Trifolium alexandrinum L.) cultivars.

Background: Berseem clover is the main forage crop grown in Mediterranean regions. There are plenty of cultivars that possess variability in their productivity and quality among the different cuts. Therefore, accurate agronomic and qualitative characterization is crucial for selecting the most promising cultivars for breeding and feeding purposes.
