THE INFLUENCE OF IRRIGATION AND NITROGEN FERTILIZERS ON THE AUTUMN WHEAT PRODUCTION IN DOBROGEA CONDITIONS PUBLISHEDLiliana Panaitescu
This paper presents the production results obtained in wheat fertilized with N doses of 50, 100 and 150kg/ha, compared to the control variant unfertilized with nitrogen, and the effect of two irrigation norms, 400 mm and 750 mm, respectively, compared to the non-irrigated control variant. During the experimentation years (an average of three years), the production of the N fertilized wheat (50 kg/ha) was higher by 6.67 q/ha compared to the unfertilized control variant. In the version fertilized with 100 kg/ha, the production was higher by 11.84 q/ha, compared to the unfertilized control variant. In the version fertilized with 150 kg/ha, the production was higher by 16.07 q/ha, compared to the unfertilized control variant. Regarding the irrigation norms, in the version irrigated with 750 mm water/ha, the production was higher by an average of 7.7 q/ha compared to the non-irrigated wheat, while in the version irrigated with 400 mm water/ha, the production obtained was higher by an average of 3.4 q/ha compared to the non-irrigate wheat.
