e0“following variable-rate fertilization on barley”
e2“Four N fertilization treatments were performed: (i) conventional– 150 kg ha−1; (ii) variable with granular fertilizer; (iii) variable with foliar liquid supplement; (iv) no fertilization”
e3“Results showed that both site-specific fertilizations ensured the maintenance of high yields with a significant N rate reduction (approximately by 75%) and a N use improvement”

Other claims from this paper (5)
- Intervention effect Cumulative GHG emissions under sensor-based N application were not significantly different from conventional fertilization in barley.
- Intervention effect Site-specific fertilizations reduced the barley N rate by approximately 75% relative to conventional fertilization.
- Intervention effect Site-specific fertilizations improved N use in barley relative to conventional fertilization.
- Intervention effect Variable-rate N fertilization gave barley yields similar to conventional fertilization, about 6 t/ha.
- Intervention effect Barley grain protein content was higher in the foliar variable-rate treatment (14%).
