ORGANIC RESIDUES IN THE CULTURE OF CHRYSANTHEMUM AND THE PHYSICAL ATTRIBUTES OF THE SOIL

Abstract

The objective of this work was to evaluate the use of organic residues in the culture of chrysanthemum and the physical attributes of the ground. The objective of this work was to evaluate the use of organic residues in the culture of chrysanthemum. The experiment was carried through in protected culture, the UNIOESTE, Campus of Marechal Cândido Rondon/Brazil, with the culture of chrysanthemum, in Latosol Red soil. The experimental design was entirely in randomized blocks with 7 treatments and 4 repetitions: T1 (mineral fertilization), Treatment 2, 3, 4 and 5 (10 Mg ha-1 of vermicomposite, poultry manures, composting of vegetables and litter coat). Parameters three samplings had been determined: height, floral number of secondary connecting Agrarian, v.1, n.1, p. 21-35, jul./set. 2008. 2 2 Agrarian, v.1, n.1, jul./set. 2008 2 rods, leaves, buttons and inflorescences, diameter of connecting rod, and inflorescences. The characteristics of the ground and end of the experiment had at the beginning been: particle and ground texture, density, aggregate porosity and stability. The results had been evaluated by software STAT. The results had allowed to conclude that the different organic residues used the use of aviary bed determined higher plants; the system to root was not modified; it had increase of the total porosity, bed increased the macro porosity; the use of organic residues improved the alone structure of the soil, used of aviary bed sends regards to it, as source of organic material for the culture of chrysanthemum.
