Nutrição mineral e produção de mangueiras 'Tommy Atkins' adubadas com diferentes materiais orgânicos no semiárido paraibano.

Abstract

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.
