Résumé:
Organic materiais of animal origin are important sources of nutrients for the
horticulture irrigated in the semiarid Paraibano, not having, however, information of
her use on the nutritional and productive aspects of the main cultivated species. This
work aímed at to evaluate the nutritional state and the production of mango trees
'Tommy Atkins', fertilized with different organic materiais in the semiarid Paraibano.
The experiment was driven, in the years of 2010/2011 and 2011/2012, in
delineamento entirely casualizado. with eight treatments and ave repetitions. The
treatments consisted of six organic materiais [poultry manure (PM), caule manure
(CM), sheep manure (ShM), swine manure (SwM), poultry litter (PL) and organic
compost (OC)], synthetic fertilizer (NPK) and a contrai (without fertilization). They
were appraised the leaf contents of N, P and K, the relationships N/P, N/K and P/K
and the components of the production (number of fruits for plant, medium mass of
fruits, production for plant and productivity). Manga trees 'Tommy Atkins' irrigated,
with 15 years of age, in production phase in Neossolo Flúvico of the Meadows of
Sousa don't answer the manuring mineral or organic.
