PERTUMBUHAN DAN HASIL TANAMAN KEDELAI EDAMAME (Glycine max (L). Merr) PADA BERBAGAI JARAK TANAM DAN WAKTU PENGENDALIAN GULMA

Abstract

Edamame (Glycine max L. Merill) is a type of horticultural plant that can grow in tropical
areas. Nowadays, edamame has become an exclusive snack so that it is always available in modern
markets. Information on weed control in edamame cultivation is very useful for increasing production.
This research aims to: 1) Evaluate the interaction of planting distance with weed control time on
edamame growth and yield, 2) Determine the right planting distance to increase edamame growth and
yield, 3) Determine the right weed control time to suppress the rate of weed growth in edamame
plantations. The study was conducted from August to October 2021 in farmers' land, Bentiring
Village, Muara Bangkahulu District, Bengkulu City. The study used a Complete Randomized Block
Design (RAKL) with two factors and three replications. The first factor was the planting distance
232
consisting of three levels, namely: J1 = 20 cm x 12.5 cm, J2 = 20 cm x 25 cm and J3 = 20 cm x 37.5
cm. The second factor was the weed control time consisting of four levels, namely T1 = clean weeds
(weeds are controlled once a week), T2 = weeded 15 days after planting (dap), T3 = weeded 15 dap
and 30 dap, and T4 = weeded 15 dap, 30 dap, and 45 dap. The results showed that there was no
interaction between planting distance and weed control time on all observation variables. A planting
distance of 20 cm x 12.5 cm (J1) was the most appropriate planting distance to increase plant height,
weight of full pods per plot, and total pod weight per plot. Meanwhile, the 4 weed control times tested
had no significant effect on all edamame observation variables.
