N2  - The content of eight elements (N,P,K,Ca,Mg,Zn,Fe, and Mn) was evaluated in straw of ripened rice plants that had been artificially inoculated with the rice giallume virus (RGV) using the aphid Rhopalosiphum padi (L.) as vector at the first lead stage and a tiller initiation. The results obtained in 11 Italian varieties pointed out a great difference both between the infected plants and the check and between the plants inoculated at different phenological stages. Since concentrations of the eight nutrients were very different in the healthy plants compared with the diseased ones, RGV is believed to affect the metabolism of these elements
