The aim of this study was to compare the asparagus bean cultivation conducted in different staking and spacing systems. The experiment was conducted in the design of randomized blocks in a factorial scheme (4x3) with four replicates. The first factor was constituted by four staking types [narrow ribbon vertical (FV), “V” normal (VN), inverted “V” (VI) and creeping (R)]. The second factor was constituted of three plant spacing (20, 40, and 60 cm), keeping constant the spacing of 1 m between crop rows. The evaluated characteristics were precocity (cultivation cycle); number of pods, mass of grains and pods per plant; length of pods; number of grains and mass of grains per pod; grain and pod yield. The gas exchange as well as the cost of deploying each of the treatments were also evaluated. The density of 50,000 plants/ha (spacing of 20 cm) provided the highest productivity in the FV and VI systems, with 9.10 and 6.72 t/ha, in addition to promoting higher net income to the producer, with averages of approximately 23 and 15 thousand R$ above R system. For the gas exchange variables, there was a reduction in net photosynthesis with density increase. The use of higher planting densities are indicated, combined with the use of FV and VI systems, in detriment to R system. The higher planting densities generate higher productivity and net income to the producer.</p><p></p>
