Agronomic Efficiency of Organic Fertilised in the Production of the Intercropping of Coriander and Mint in the Northeastern Brazil

Abstract

Oleric plants are grown in a system intercropping by family farmers in organic production areas in the region northeastern Brazil. The experiment was conducted in an experimental area belonging to a semi-arid rural federal university. The study was carried out in the period from August 2014 to November 2014, in order to evaluate agronomic efficiency of organic fertilised in the production of the intercropping of coriander and mint in the northeastern Brazil. The study area was designed in a randomized block area, arranged in a 2 x 4 factorial scheme set up, with three replications. The first factor set up consisted of single crop and intercropping of coriander and mint, and the second was hairy woodrose  (Merremia aegyptia L.) added to cattle manure in the amounts  (0.0, 2.0, 4.0 and 6.0 kg/2.0 m2). The evaluated characteristics for the coriander crop these were plant height, number of stems, green mass, number of bunches and dry mass. The evaluated characteristics for the mint crop these were biomass height, green mass, number of bunches, dry mass, oil content and yield oil. The agronomic efficiency of mint and coriander in intercropping was was obtained with the addition of 6.0 kg/2.0 m2 of organic fertilised incorporated into the soil. The equivalent area ratio was agronomically efficient, with equivalent area ratio (EAR) of 1.66.
