Uso de gesso agrícola para atenuar o déficit hídrico em plantas jovens de mogno africano no cerrado

Resumo

Among the species used for the extraction of noble wood, African mahogany (Khaya ivorensis) has diverse economic potentials. Commercial planting of this species is growing, covering most Brazilian states. Thus, information on the development of this species in the field, under specific conditions in each region, is essential to ensure adequate performance and quality. The difficulty in cultivation is related to the water deficit in the region along with the nutritional insufficiency present in the soil. The objective of this work was to evaluate African mahogany plants submitted to increasing doses of agricultural gypsum grown in the Cerrado. The experiment was implemented at Fazenda Entre Rios - Brasília (DF), Brazil, in an African mahogany forest (Khaya ivorensis) of 1.44 ha-1 (120x120 m) planted in January 2013 in the 6 x 4 m spacing (total of 60 plants) , in a randomized block design. The five treatments consisted of doses of 0, 12, 24, 36 and 48 kg plant-1 of gypsum, corresponding to 5, 10, 15 and 20 t ha-1, respectively, and evaluated for 58 months (2013 to 2017). The results showed that the gypsum doses used did not show significant effects on the development of young plants (height and diameter).
