e0“The time to phenological stages was similar between treatment. The N and in minor degree the P increased grain yield (GY) and oil yield (OY) by increases in the grains number (GN), capitulum area (CA), canopy dry matter (CDM) and radical area (RA). In contrast, the P increase RDM but decrease the CDM/RDM relation. The effect of the interaction N * P on GY, OY indicates it is necessary to seek the best combination of …” Show full quote
