Componentes agronômicos e nutrição mineral da canola adubada com cama de aviário

Abstract

The aviary bed is an organic residue that can be used as fertilizer for crops such as canola which requires high demand for nutrients. The objective of this work was to evaluate agronomic characteristics, yield and oil content of the canola which used the poultry avian litter. The experiment was conducted in the field in a randomized complete block design with four replicates. The treatments were the doses of 0, 1, 2, 4, 8, 16 and 32 T ha-1 of poultry litter from 6 lots of chicken production. The hybrid Hyola 433 was used. The sowing was carried out on May 6th and the harvest on September 30th, totaling a cycle of 145 days in total. The line spacing used was 0.5 m, resulting in a density of 400.000 ha-1 plants. In the experimental conditions, it can be concluded that in the canola crop, fertilization with aviary litter does not interfere in the nitrogen and potassium foliar contents, at plant height, in the number of grains per silica, in the number of silicas per plant and in the mass of thousand grains. The foliar content of phosphorus increases from the dose of 16 T ha-1 as dose increases. The highest productivity (2503 kg ha-1) and the highest oil content (43.2%) were obtained with the dose of 8 T ha-1.
