Comparisons among barley–pea mixed crop combinations in a replacement design as related to N fertilization and soil variation

General information

Two field trials were carried out in 2017 and 2018 at the Experimental Farm of the Università Politecnica delle Marche (UNIVPM), Ancona, central Italy. The experimental area was in the lower portion of a hilly slope at an altitude between 46 and 48 m, with a S-SE exposure and gentle inclination (< 5%). Here, soils developed from semi-coherent and sub-alkaline Plio-pleistocene marine sediments, have a thickness that is usually below 1 m and a silty clay loam texture, and show rather frequent formation of shallow vertic cracks over the years. The experimental farm is…
