Arranjos de cultivo em consórcio entre Rúcula e Nirá (Allium tuberosum Rottler ex Spreng)

Abstract

Intecropping stands out as an alternative for producers of vegetables that seek to achieve increments in agricultural production with more sustainability. In this system, different species are grown in the same area, which allows greater efficiency in land use and inputs. However, in view of the diverse possibilities of associations, adjustments regarding crop arrangement are necessary to guarantee the superiority of intercropped crops in relation to monoculture. In this sense, the objective of the present work was to evaluate the productive performance and the biological efficiency of the intercropped arugula cultivar with nira under different crop arrangements. The experiment was carried out in the Didactic Garden of the Federal University of Ceará, from July to November, 2017. The experimental design was a randomized complete block design with five treatments and four replications. The treatments were: T1 (single arugula cultivation), T2 (single crop of Nira), T3 (intercropped cultivation of two arugula cultivar lines with three nirá - 2R: 3N cultivar lines), T4 arugula cultivar lines with two rows of 2NR: 2N) and T5 (intercropped cultivation of two arugula cultivar lines with a 2R: 1N row). The productive characteristics of the crops and the indicators of the biological efficiency of the crops were evaluated. Single roughage cultivation and 2R: 1N intercropping achieved similar productivity, but the 2R: 1N intercropped crop showed the highest productive efficiency, with a UET of 1.16% and the arugula had a relative contribution of 84.3% in the productive yield of the system. It is concluded, therefore, that the 2R: 1N intercropper can be used for the greater optimization of the productive inputs in arugula cultivation.
