| Popis: | The response of durum wheat cultivars to different nitrogen levels was investigated in a field experiment in the sub humid area of Tunisia between ten durum wheat genotypes: seven improved genotypes and three landraces grown under three mineral N fertilization levels (0, 75 and 150 kg N.ha-1) during the cropping season 2015–2016. Allmost all growth parameters showed a significant effect (p < 0.05) between tested genotypes and applied levels. Therefore, There was a significant difference (p < 0.05) between improved genotypes and landraces for all yield components and NAE. Maali and Salim seem to respond better at the high N rate than the other tested genotypes. |
