Resumen
The objective of this study was to evaluate the sustainability and agro-economic viability from two croppings of coriander (C) and two of arugula (A) intercropped with beet (B) as a function of roostertree additions to the soil in different population densities. The experimental design was a randomized complete block, with treatments arranged in a 4 x 4 factorial scheme with four replications. The treatments resulted from the combination of four amounts of roostertree biomass (6, 19, 32 and 45 t ha(-1) on dry basis) with four population densities of coriander, beet and arugula (20(C)-50(B)-20(A)%, 30(C)-50(B)-30(A)%, 40(C)-50(B)-40(A)% and 50(C)-50(B)-50(A)% of the recommended densities in their single crops). The maximum agronomic efficiency of the polyculture of coriander, beet and arugula was obtained with the density of 40(C)-50(B)-40(A) and the amount of 19 t ha(-1) roostertree biomass incorporated into the soil. The highest profitability of the polyculture was obtained with the density of 20(C)-50(B)-20(A) (%) and the amount of 45 t ha(-1) of this green manure. High agro-economic efficiency can be obtained by cultivating the polyculture of coriander, beet and arugula when well-manageding the factors of production, fertilization with roostertree and population densities.
