In recent decades, nitrogen fertilization rates have increased significantly in irrigated rice fields in southern Brazil. However, there
is a gap in knowledge concerning the use of these high rates of nitrogen fertilization in cultivars with a high yield potential, and
susceptible to rice blast. We therefore conducted a field experiment in the 2014/2015 and 2015/2016 crop year to evaluate blast
severity, plant tissue nutrition, and yield and grain quality with increasing nitrogen fertilization levels in a rice blast-susceptible
cultivar (Guri Inta CL). The experiment had three factors, with factor 1: N doses (0, 60, 120, and 180 kg ha−1
), factor 2: sowing dates (early and late), and factor 3: with and without fungicide application. The experimental design was randomized blocks with
four replications. The area under the disease progress curve was positively influenced by the increase of N rates in the two crops
years. Grain yield had a negative quadratic effect as a function of N rates. Increased N levels reduced the thousand grains weight.
Late sowing and non-application of fungicide increased disease severity; there was reduced yield, grain quality, and N use
efficiency. It is concluded that the use of N levels greater than 60 kg ha−1 in rice blast-susceptible cultivars in southern Brazil
increases disease severity with lower N use, reduces grain yield and grain quality. |
