Biofertilizante suíno na produção e qualidade do óleo de girassol (Helianthus annuus L.)

Abstract

In the Brazilian Northeast there are innumerable sustainable technologies that aim to take advantage of internal inputs that would be discarded, and which can add value and contribute directly to organic vegetable production in the rainfed family agriculture. Our experiment was developed at the Federal University of Paraíba, within the Postgraduate Program in Agrarian Sciences and Agroecology, conducted in the discipline of Agroecological Systems of Vegetable Production, where we can develop a sunflower planting, spacing 0.30 x 0.70m (0%, 20%, 40% and 60%) were applied in a randomized complete block design, which was applied to the pig biofertilizer (liquid swine manure). Expect to take part in the biofertilizer contribution, to potentiate sunflower seed production, having seen the interactions of the necessary and provided nutritional characteristics. It is extremely satisfying to develop a field work of such importance in a postgraduate course, knowing of all the difficulties with the various contents and the short time available, but to know that we can contribute directly to the organic family production our group work is already validated. Gratitude!
