Effects of cover crop residue management on yield and weed controlin processing tomato

Summary

The aim of this poster is to evaluate the effects of different subsidiary crop species and their residue management on weed control and fruit yield of a tomato crop in the Mediterranean environment of Central Italy. A field experiment was set up in September 2012 at the experimental farm of Tuscia University (UNITUS). A 2-year durum wheat – tomato sequence was adopted. The treatments consisted in:
(i) 4 different cropping sequences (Fig. 1);
(ii) 2 cover crop residue management [residues mowed and left in strips on soil surface in no-tillage (NT) and residues chopped and incorporated into the soil (T)];
(iii) 3 nitrogen fertilization levels to the durum wheat and tomato [0% (N0), 50% (N50), and 100% (N100) of total nitrogen recommended dose].
