Effect of various dosage of ammonium glufosinate herbicide on suppressing weeds and growth and yield of corn

Corn is one of the strategic food commodities in Indonesia which is currently widely used as animal feed ingredient. But the average productivity of national corn is still low. This study aims to determine the dose of herbicide ammonium glufosinate ۲۰۰ g/L which can maintain the growth potential and yield of corn plants. The experiment was carried out at the Ciparanje Experimental Garden of the Faculty of Agriculture, Padjadjaran University, Jatinangor, Sumedang Regency, West Java, with altitude of ۷۵۰ meters above sea level in November ۲۰۱۷ to March ۲۰۱۸. The experimental method used was a randomized block design consisting of seven treatments which were repeated four times. The treatments tested consisted of: manual weeding, application of different doses of ammonium glufosinate (۴۵۰, ۶۰۰, ۷۵۰, ۹۰۰, and ۱۰۵۰ g/ha) and unweeded check. The results of the experiment showed that application of ammonium glufosinate ۲۰۰ g/L herbicide is able to suppress weed growth in corn cultivation. The application of ammonium glufosinate ۲۰۰ g/L herbicide starting from a dose of  ۶۰۰ g/ha is effective in suppressing weed growth and suppressing the loss of yield of corn due to the presence of weeds.
