Agronomic Characteristics and Productivity and Oil Content of Canola Crop as a Function of Poultry Litter Use

Abstract

Aims: Poultry litter is an organic residue that can be used as fertilizer for crops such as canola that require high nutrient demand. The objective of this research was to evaluate agronomic characteristics, productivity and oil content of canola crop as a function of poultry litter use. Study Design: The experiment was conducted in the field in a randomized block design with 4 replications. Place and Duration of Study: The experiment was carried out in a property in the city of Serranópolis do Iguaçu, state of Paraná, between May and September, 2016. Methodology: The treatments were the doses of 0, 1, 2, 4, 8, 16 and 32 t ha-1 of poultry litter from 6 lots of broiler chickens production. Hyola 433 hybrid was used. Sowing was performed on May 6 and harvest on September 30, totaling a 145-day-cycle. The row spacing used was 0.5 m, resulting in a density of 400 thousand plants ha-1. Results: In canola cultivation the poultry manure fertilization does not affected the leaf N and K contents, plant height, number of grains per silica, number of silica per plant and thousand grain mass. The leaf P content increased from the 16 t ha-1 as the doses increase. The highest yield (2.5 t ha-1) and the highest oil content (43.2%) were obtained with the 8 t ha-1 dose. Conclusion: In conclusion the canola fertilized with poultry litter was significant for some variables and for the productivity and quantity of oil in the treatment of v) 8 t ha-1 and vi) 16 t ha-1 for phosphorus content in leaf tissue. It is also concluded that high doses of poultry litter doses not provide increase in canola crop variables.
