The aim of the current study was to assess the performance of Canavalia ensiformis and Mucuna deeringiana (Leguminosae) as a green manure in the agricultural soil of the Frailesca region of Chiapas, México, in terms of aboveground biomass accumulation, plant height, number of leaves, canopy coverage, and the accumulation of nitrogen (N), phosphorus (P), and potassium (K). Each species was sowed at two population densities under a randomized complete block design with three replications. Every 30 days after sowing (DAS), the following variables were quantified: plant length, number of leaves, canopy coverage, biomass yield, and N, P, and K content. A variance analysis and mean comparison test (Tukey 0.05) were performed for each variable. The biomass yield in M. deeringiana fluctuated from 9150 to 33,160 kg ha-1 on a fresh basis and from 4490 to 15,890 kg ha-1 on a dry basis, whereas the yield in C. ensiformis varied from 9343 to 26,390 kg ha-1 and from 4513 to 13,150 kg ha-1, respectively. The longest recorded plant length was 513.00 cm in M. deeringiana and 155 cm in C. ensiformis, with a total of 353 and 322 leaves, respectively. The accumulation of N, P, and K was 463.99 kg ha-1, 84.22 kg ha-1, and 49.26 kg ha-1 in M. deeringiana and 341.90 kg ha-1, 43.40 kg ha-1, and 36.82 kg ha-1 in C. ensiformis, respectively. Both C. ensiformis and M. deeringiana have potential as green manure for the Frailesca region of Chiapas in terms of biomass production and N accumulation.
