ARAUJO DIAZ, Rogelio et al. Ecophysiological and numerical traits of broad bean yield affected by cultivar, population density and sowing system. Rev. Mex. Cienc. Agríc [online]. 2023, vol.14, n.1, pp.51-62.  Epub 19-Jun-2023. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v14i1.2992.

A field experiment was established with the objective of evaluating the effect of two sowing systems, three densities and three cultivars on the ecophysiological and numerical traits of the seed yield of broad bean var. Major. The three broad bean cultivars (amarilla, diamante, monarca) were sown in plots of three furrows 3 m long and separated at 0.8 m (traditional system: TS) and 0.4 m (alternative system: AS) and in three population densities (5, 10 and 15 seeds m-2). To achieve the desired density, two seeds were deposited every 25, 12.5 and 8 cm (TS) and every 50, 25 and 16 cm (AS). The experimental design was a randomized complete block design with four serial repetitions. The results showed significant effects for sowing systems, density and cultivar. The AS obtained the highest biomass production and grain yield relative to the TS. Increasing population density increased seed yield due to a higher number of seeds per unit area and a higher number of pods m-2. Showing that the greatest variability in this experiment was due to the increase in sowing densities, followed by the distances between rows (AS 40 cm) and (TS 80 cm). The Monarca genotype obtained the highest seed yield, while Amarilla presented an increase in weight of 100 seeds. It was observed that each cultivar presented a different behavior for the generation of yield.
