The Effect of Weed Control on the Growth and Yield of Shallot (Allium ascalonicum L.)

Abstract

Weeds are one of several factors that cause decreased shallot production. Weed control is needed to increase production. The experiments to study the effect of weed control on the growth and yield of shallot had been conducted from June 2019 to September 2019 at Kepuharjo Village in Karangploso Sub- District, Malang Regency. The experiment used a randomized block design (RBD) with 6 treatments and 4 replications. The results showed that for treatment of weed-free, weeding at 15, 30 and 45 DAP (Days after planting), application of oxyfluorfen herbicides at a dose of 1.5 l /ha + weeding at 30 DAP, silver black plastic mulch + weeding at 30 DAP and straw mulch rice + weeding at 30 DAP the dry weight of weed significantly decreased. The growth and yield of shallot showed significantly higher with weed free treatment followed by weeding 15, 30 and 45 DAP, application of oxyfluorfen herbicide at a dose of 1.5 l/ ha + weeding at 30 DAP, silver black plastic mulch + weeding at 30 DAP and rice straw mulch + weeding at 30 DAP treatments. The growth and yield of shallot showed significantly lower with the treatment of without weed control compared with the other weed control treatments.
