Abstract
Weeds become competitive plants for rice
plants in obtaining nutrients, water, light, space and allelopathy. This study
aims to determine the effect of the herbicide 2,4-D dimethyl amine 866 g/l to
control weeds on the growth and yield of rice plants. This research was
conducted from February 2023 to May 2023 at the Agricultural Development
Training Research Center (SPLPP), Faculty of Agriculture, Padjadjaran Ciparay
University, Jlengkong Village, Baleendah District, Bandung Regency, West Java
Province. The experiment used a randomized block design (RBD) with six
treatments and four replications. The experiment consisted of four herbicide treatments
with the active ingredient 2,4-D dimethyl amine 866 g/l with doses A: 1.5 l/ha,
B: 2.l/ha, C: 2.5 l/ha, D: 3 l /ha, E: manual weeding treatment and F: control
treatment. The results showed that the application of the herbicide with the
active ingredient 2,4-D dimethyl amine 866 g/l at a dose of A: 1.5 l/ha to 3
l/ha had a good effect on suppressing weed growth and yields of lowland rice
production and the herbicide dose was 2, 4-d Dimethyl aminan 1.5 l/ha is the
most effective dose in suppressing the growth of weeds Sphenoclea zeylanica,
Hordelymus E., Cyperus esculentus, Limnocharis flava, Poa trivalis,
Fimbristylis dichtoma, Luwdwigia octovalvis, Luwdwigia peruviana found in rice
cultivation land paddy fields, and affects the number of tillers of rice
plants, rice yields and does not cause phytotoxicity to rice plants.
