Application of increasing doses of phosphor in Cordia trichotoma seedlings

The objective of this work was to evaluate the initial response of Cordia trichotoma seedlings to increasing doses of phosphorus application. The experiment was carried out in a randomized block design, with five treatments (0, 150, 300, 450 and 600 mg dm-3 of P) in five replications. It was evaluat...

It was evaluated at 30, 60, 90 and 180 days at height, stem diameter, robustness index (H/DC), shoot dry mass (MSPA), root system dry mass (MSR), MSPA/MSR, total dry mass (MST) and the Dickson Quality Index (IQD).
