Control of Weeds with Amonium Glufosinat in Tomato (Solanum lycopersicum L.) Cultivation

Abstract

One reason for the low production of tomato is the presence of weeds. Weeds compete with the crop and there fore need to be controlled. One of weed control methods is chemical weed using herbicide with ammonium glufosinate content. This study aims to obtain an optimal dose of ammonium glufosinate to control common weeds in a tomato field. The research used non-factorial randomized block design with 7 treatment levels ammonium glufosinate as follows 225 g.a.i/ha,300 g.a.i/ha,375 g.a.i/ha,450 g.a.i/ha,525 g.a.i/ha manual weeding,without herbicide and manual weeding. The results showed that ammonium glufosinate at the rate of 525 g.a.i/ha herbicide was not significant different with manual control, weed control with ammonium glufosinate herbicide caused phytotoxicity Using higher dose,higher the phytotoxicity. The dominant weeds from the observation plots was Eleusine indica at 22.40% which can be controlled at a dose of to 525 g.a.i/ha. Dry weed matter with herbicide ammonium glufosinat 225 g.a.i/ha to 525 g.a.i/ha and  manual weeding are significantly different from without herbicides and with manual wedding.
