Abstract
This study aimed to determine the
effectiveness of Paraquat dichloride 276 g / l herbicide in suppressing weed
growth and its effect on the development and yield of sweet corn plants. This
experiment will be conducted from November 2022 – February 2023 at the
Ciparanje Garden, Faculty of Agriculture, Padjadjaran University, Jatinangor
District, Sumedang Regency. This experiment used a Randomized Block Design (RBD)
with seven treatments and four repeats, resulting in 28 experimental plots. The
treatment in this study included Paraquat dichloride herbicide treatment 376 g
/ l (1) dose 1.50 l / ha, (2) dose 2.00 l / ha, (3) dose 2.50 l / ha, (4) dose
3.00 l / ha, (5) dose 3.50 l / ha, (6) manual weeding and (7) control. The
results showed that Paraquat dichloride herbicide 276 g / l starting at a dose
of 1.50 effectively suppressed the growth of weeds Bidens pilosa, Alternanthera
sessilis, Euphorbia hirta, Cynodon dactylon, other weeds at 3 WAA to 6 WAA.
Paraquat dichloride 276 g / l herbicide does not cause phytotoxicity in sweet
corn plants. It indirectly influences the growth and yield of sweet corn plants
by suppressing weed growth so that competition between weeds and sweet corn
plants can be avoided and sweet corn plants can grow and produce sweet corn
according to their potential.
