Influência de nitrogênio e matéria orgânica na produção de melão (Cucumis melo L.)

Abstract

The influence of nitrogen, micronutrients (Boron, Molibden and Zinc) and organic matter was evaluated in the melon (Cucumis melo L) production and quality o f fruits. The experiments were conducted in two Experimental Station EMBRAPA - SEMIÀRIDO, located in the municipal of Petrolina-PE and Juazeiro-BA, Brazil, among the period of October to December of 2000, with the following treatments: control and two rates of N (80, 160 kg/ha) being the first rate isolated applied and in combination with the micronutrients boron, molibden and zinc (1,2; 0,4; 4 kg/ha, respectively) and organic matter (20 m3/ha) using the experimental design in blocks with eight treatments and four repetitions. In relation to the total productivity, in the Experimental Station of Bebedouro, the melon crop answered to the applications of nitrogen, micronutrients and organic matter, what didn't happen in the Experimental Station of Mandacaru. The medium weight of the fruits produced in the Experimental Station of Bebedouro was not influenced by those treatments and in the Experimental Station of Mandacaru just the application of nitrogen together with organic matter influenced the medium weight of the fruits. In relation to the text of Brix, in the Experimental Station of Bebedouro the melon crop answered, in a lineal way, only to the application of nitrogen. In the Experimental Station of Mandacaru there was not answer of the melon crop to the application of nitrogen, micronutrients and organic matter.
