Abstract The objective of this study was to evaluate and estimate the post-harvest indices and color parameters of beet roots in intercropping with lettuce under green manuring with different equitable amounts of M. aegyptia and C. procera biomass (20, 35, 50 and 65 t ha-1 on a dry basis) in diverse population densities of lettuce (150, 200, 250 and 300 thousand plants ha-1), in two cropping seasons in semi-arid environment. The lettuce crop presented the best post-harvest indexes when submitted to fertilization with an amount of M. aegyptia and C. procera biomass of 20 t ha-1 in lettuce population densities between 203 and 300 thousand plants per hectare. The beet crop reached the best indices when it was manured with amounts of the green manures between 20 and 55 t ha-1 and between lettuce population densities of 150 and 300 thousand plants per hectare. The color parameters of purple/red beet roots (well appreciated by the consumers) were obtained in the amounts of green manures between 25 and 65 t ha-1 and between lettuce population densities of 280 and 300 thousand plants per hectare.
