Consórcio de coentro com beterraba, adubados com doses de jitirana, combinada com esterco bovino no desempenho agroeconômico.

Abstract

The use of the mixture of organic fertilizers is constituted in alternative for farmers who produce in agroecological system because it contributes to the reduction of production costs and most efficient in the use of inputs available in the production areas. Given the above, it was aimed to evaluate the intercropping system of coriander and beets fertilized with hairy woodrose doses combined with cattle manure in agroeconomic performance. The experiment was conducted at the Fazenda Experimental Rafael Fernandes, in Alagoinha district, a rural area of Mossoró-RN, from September to December 2014. The experimental design was of randomized complete blocks with treatments arranged in a factorial 2 x 5 with three replications. The first factor was constituted by monocropping and intercropping of coriander and beet. The second factor by the hairy woodrose doses combined with bovine manure (0.0; 1.0; 2.0; 3.0 and 4.0 kg m-2 of bed). The beet cultivar planted was 'Early Wonder' and of coriander was 'Verdão'. In beet crop were evaluated the following characteristics: plant height, leaf number per plant, root diameter, commercial productivity of roots and dry mass of roots. For the coriander crop the following characteristics were evaluated: plant height, number of stems per plant, productivity, number of bunches and dry mass. Economic indicators were also used, such as gross income, cost of production, net income, rate of return, profit margin. The best agroeconomic performance of the intercropped system was obtained at a dose of 4.0 kg m2 of bed, with gross income of R $ 14,940.00; production cost of R $ 3,306.00; net income of R $ 11,634.00; return rate of R $ 4.52 and profit margin of 77.87%, for a 900 m2 production area. The intercropping system had a land equivalent ratio of greater than 1.0, with an mean value of 1.85 in the dose of 4.0 kg m-2 of hairy woodrose bed mixed with cattle manure. The intercrop has contributed for better use of available resources without compromising the quality of commercial products. This technique of fertilizer mixing (hairy woodrose with manure) proved to be efficient in organic production of the intercropping system of the coriander with beet.
