Abstract

The intercropping of plants presents itself as one of the most appropriate methods for the practice of olericultura, in agroecological molds, with innumerable advantages in the environmental, productive and economic aspect. In this sense, the objective was to evaluate residue cashew nuts doses in the agronomic performance of the intercropping of mint with carrot. The experiment was conducted in an experimental area belonging to a semi-arid rural federal university, in the period from September 2016 to February 2017. The study area was designed in a randomized block, 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 mint and carrot, and the second was doses of cashew nut residue (0.0, 1.5, 3.0 and 4.5 kg m-2).The evaluated characteristics for the mint crop these were biomass height, green mass, number of bunches, dry mass, oil content and yield oil. For the carrot crop, the following characteristics were evaluated: biomass height, root length, root diameter, root yield, root dry mass, green mass and dry of the area. The use of cashew nut residue was efficient in promoting increase in the productive characteristics of the intercropping, with 40 units of sauces m2 of mint and oil yield of 133.57 g 100 m-2. For the carrot crop, commercial yield of 4852.6 g m-2 at the 4.5 kg m-2 dose of cashew nut residue was observed. The intercropping proved to be efficient with equivalent area ratio of 1.83.
