Abstract

Weeds are one of the shallot problems because they compete with the plants for nutrients, light, water, and a place to grow. The research to determine the effect of weed control at different spacings used a Split Plot Design. The main plots were plant spacing, consisting of 10 cm × 10 cm, 15 cm × 15 cm, 20 cm × 20 cm (J3). Weed control was as sub-plots consisting of weed-free, weeding 14, 28, and 42 DAP (Days After Planting), pre-emergence herbicide oxyfluorfen + weeding 28 and 42 DAP and silver black plastic mulch + weeding 28 and 42 DAP. The results showed that the dry weight of weeds was significantly smaller at plant spacing of 15 cm × 15 cm  and a plant spacing of 20 cm × 20 cm. Plant height was higher at plant spacing of 10 cm × 10 cm. The number of tillers and tuber dry weight per plant was higher at a plant spacing of 20 cm × 20 cm. The yield of tubers was higher at plant spacing of 10 cm × 10 cm  than at plant spacing of 15 cm × 15 cm  and plant spacing of 20 cm × 20 cm. There were no significant differences in plant height, number of tillers, and tuber yield of shallot plants between weed control treatments.
