Resumen:
The use of the organic fertilizer mixture is an alternative for farmers who produce in an agroecological system, as it contributes to the reduction of production costs and greater efficiency in the use of the inputs available in the production areas. In this sense, the objective was to study the agronomic viability of mint (Mentha piperita L.) under quantities and forms of application of the jitirana mixture plus bovine manure. The experiment conducted at the experimental farm Rafael Fernandes from 08/24/2017 to 11/23/2017, in the district of Alagoinha, rural area of Mossoró – RN. The experimental design was a randomized complete block design in a 5 x 2 factorial scheme, with four replications. The first factor consisted of the quantities of the mixture of jitirana plus bovine manure (0, 0, 1, 4, 2, 8, 4, 2 and 5, 6 kg / m2), the second factor was composed by the way of handling the mixture of jitirana and bovine manure (incorporated and in cover). For the mint crop, the cultivar Mentha piperita planted. The following characteristics evaluated biomass height, yield, and dry mass, number of sauces, oil content and yield. No interaction observed between the amounts of jitirana and the forms of management of jitirana plus bovine manure in any of the characteristics evaluated. The best yield of mint (1.5 kg / m2), number of sauces (16.4 units / m2), oil percentage (6.73 g / kg) and oil yield (1.37 g / m2) observed in the amount of 4.2 kg / m2 of jithrana. Among the management methods, the incorporation of jitirana plus bovine manure was statistically superior when it was covered, except for oil yield, with values of 1.7 g / m2 mint yield, 15.8 sauces / m2 and 6.8 g / kg oil percentage.
