Abstract

Fertilizers and soil management interfere in the nutritional status and growth of plants.
In this context, organic pear production using specific nutrient sources (organic and/or mineral) may limit tree development and/or production.
The objective of this study was to evaluate the nutritional status and vegetative growth of ‘Cascatense’ pear trees fertilized with different poultry litter concentrations, alone or in combination with basalt powder.
Higher foliar N, Mg, K and Ca contents were found in the treatment with 2 kg tree^‑1 of poultry litter + 2 kg tree^‑1 of basalt powder.
For this treatment, N content was higher than recommended, K content in the normal range and Ca content below the normal range.
The higher leaf content of S was observed for treatment with 4 kg of poultry litter, with levels above recommended.
There was no significant increase for foliar S, Fe, Zn and B content.
Application of 2 kg of poultry litter + 2 kg of basalt powder significantly increased leaf dry mass, showing higher vegetative growth.
