Efikasi Herbisida Campuran Atrazin Dan Mesotrion Untuk Mengendalikan Gulma Pada Budidaya Tanaman Jagung ( Zea Mays L.)
Abstract: Maize (Zea mays L )
is the most important food crops in the world beside rice and wheat. Weeds are one factor cause decrease
productivity of maize. The objectives of
this research were to know of dose combination atrazine and mesotrione
herbicide to control the weed in maize field and how was the atrazine and
mesotrione effect to maize. The research
was conducted in Natar, South Lampung and Weeds Laboratory Faculty of
Agriculture, University of Lampung, from December 2014 to April 2015. The experiment was arranged in Completely
Randomized Block Design (CRBD) with six treatments and four replications. The treatments are combination atrazine and
mesotrion herbicide rates at 500+50; 750+75; 1000+100; 1250+125; and 1500+150 g
ha-1, mechanical weeding, and control.
Homogenity of variance was tested by Bartlett test and additivitty
tested by Tukey's test, the comparison of mean were tested by Least Significant
Difference (LSD) test at 5% level. The
result showed that (1) Atrazine and mesotrione herbicide at 500+50 until
1500+150 g ha-could suppress total, sedges, Cyperus rotundus and Celosia
argenthea weed at 3 Weeks After Treatment (WAT), whereas at 6 WAT couldn’t
suppress weeds. (2) Atrazine and
mesotrione herbicide at 500+50 until 1500+150 g ha-could suppress broadleaves,
Richardia brasiliensis and Commelina benghalensis weeds until 6 WAT. (3) Atrazine and mesotrione herbicide at
500+50 until 1500+150 g ha-couldn’t suppress grasses and Rottboellia exaltata
weed until 6 WAT (4) Atrazine and
mesotrione herbicide does not affect the growth and production of maize.
