Optimizing spatial arrangement for durum wheat (Triticum durum Desf.) and subclover (Trifolium subterraneum L.) intercropping system

Summary in the original language of the document

The aim of this poster is to find a suitable spatial arrangement for the subclover living mulch-durum wheat system in order to provide a high cereal grain yield and a sufficient subclover reseeding after wheat harvesting. The study was carried out at the experimental farm of Tuscia University from 2011 to 2013. Field experiments included:
(i) 5 cropping systems including the monoculture of durum wheat and subclover and three different durum wheat/subclover intercropping spatial arrangements (Fig. 1);
(ii) 2 nitrogen fertilization levels (0 and 100 kg ha-1 of N, hereafter called N0 and N100, respectively);
(iii) 2 weed managements [weed-free (WF) and weedy (We)].
The wheat planting density was 400 seeds m-2 regardless the cropping system, while the subclover planting density was 600 seeds m-2 in pure stand, and 300 seeds m-2 in the intercropped treatments.
