Abstract :
Long bean is one of the legume plants that have great potential to be developed. To
optimize long bean seed production can be done by adjusting the plant spacing and
choosing the right form of the bamboo stick. The study was conducted with a
randomized block design (RBD) with 12 treatment combinations and repeated 3
times. The first factor is the plant spacing, which is 30 cm x 60 cm, 35 cm x 60 cm,
and 40 cm x 60 cm. The second factor is the form of bamboo stick, which consists of a
pyramid form, an upright form, and a triangle form. The results showed that the plant
spacing had a very significant effect on the parameters of leaf width, stem diameter,
pod weight per block, number of pods per block, seed weight per hectare, weight
1000 grains, percentage of germination, and significant effect on leaf length
parameter. The bamboo stick form treatment had a significant effect on the weight
parameter of 1000 grains. The interaction between plant spacing and bamboo stick
form had a very significant effect on the weight parameter of 1000 grains. In this
study, plant spacing treatment gives relatively good results, especially in the J1
treatment (60 cm x 30 cm) gives the highest production of 1.3 tons per hectare.
