Productivity of Brassica oleracea in an organic transition system in the South of Brazil
Journal Title: Revista Verde de Agroecologia e Desenvolvimento Sustentável - Year 2018, Vol 13, Issue 2
Abstract
Sustainable food production is a current paradigm of modern agriculture. Faced with the reduction of virtual stocks of traditionally agricultural fertilizer, alternative sources of fertilization can be used of systems. The present work had a significant influence on the sources of nutrients, the cultivation of butter kale, the butter prepared in organic transition. In this work four soil fertilization sources were used, forming four treatments: NPK mineral fertilizer, organic fertilizer chicken manure, limestone and rock dust. The experiment was conducted in a property in the municipality of Três Passos, Rio Grande do Sul. The experimental design was in randomized blocks with four replicates. The following were evaluated: plant height, number of plant leaves, leaf weight, plant weight and yield. The chicken manure fertilizer obtained value close to NPK mineral fertilizer regarding height, weight, number of leaves and productivity. It was verified that the treatments with limestone, rock dust, organic fertilizer chicken manure and NPK had average values, respectively, of 7, 11, 15 and 23 Mg ha-1 of productivity. The treatment with rock dust had a similar result in relation to the organic fertilizer chicken manure in all evaluated parameters. With the use of rock dust as a source of fertilization it is possible to obtain statistically similar results when the organic fertilizer chicken manure is used in feeding, evidencing the use of rock dust as an alternative source for fertilization.
