| Abstract:
A field experiment was carried out in Northern Italy (Po Valley), within the frame of the EU project SAFIR, to test the feasibility of partial root drying (PRD) management on processing tomato (2006) and to compare the PRD irrigation strategy with a regulated deficit irrigation management (RDI) (2007). PRD allowed remarkable water saving with respect to a full irrigated crop and RDI management. Water use efficiency (WUE) as well as yield and quality were assessed and compared. PRD is supposed to increase nitrogen use efficiency (NUE) as well because of improved root efficiency. Also this aspect was investigated. Furthermore, economical WUE and NUE were calculated considering the gross margin in order to evaluate the economic self-sustainability of the proposed fertigation strategies. | |
