Productive and monetary efficiency of radish and coriander intercropping under organic management

The search for cropping systems that aim at the best use of the area, optimize production, and guarantee financial profitability to the producer and his establishment in the field are challenges of modern research. Thus, the objective of this study was to evaluate the productive and monetary viability of intercropping radish-coriander fertilized with equitable amounts of hairy woodrose and roostertree biomass from the Caatinga biome at different population densities of coriander in two cropping seasons. The experimental design used was randomized blocks, with treatments arranged in a 4 x 4 factorial scheme, with four replications. The first factor was constituted by four equitable amounts of hairy woodrose and roostertree biomass (20, 35, 50 and 65 t ha−1 in dry basis), and the second factor by the population densities of coriander plants (40, 60, 80 and 100% of the recommended density in monocropping - RDM). The greatest  agronomic-monetary advantages of intercropping radish with coriander were obtained with a land equivalent coefficient (LEC) and a monetary equivalence ratio (MER) of 0.42 and 0.76, respectively, in the amounts of hairy woodrose and roostertree biomass of 20 and 39 t ha−1 added to the soil, in the coriander population density.
