The influence of three types of herbicide mixtures (atrazine at 2
kg a.i./ha, paraquat at 2 litres (0.5 kg) ai/ha and their mixture) applied
either at planting or 2 weeks after planting (WAP), were evaluated for Tithonia management. The
experiments were conducted at the Teaching and Research Farm, Ekiti State
University, Ado-Ekiti, Nigeria (April-September, 2009 and May-August 2010).
Teaching and Research Farm, Federal College of Agriculture, Akure, Nigeria
(May-August 2010) and Agricultural Machines and Machinery Training Centre,
Akure, Nigeria (July-October, 2009).The experiments were laid down in a split
plot design and replicated three times to give 18 experimental units. Data
collected on growth parameters and yield of maize as well as Tithonia density
and biomass were subjected to ANOVA and means separated by DMRT Atrazine and
resulted in significantly higher yields of 2.54 relative to the mixture of
atrazine and paraquat and paraquat which had 2.44 and 0.71 t/ha
respectively. The highest gross margin (GM) of
was obtained from the application of atrazine at 2 WAP. The highest Marginal
Rate of Returns of 2.81 was obtained from the application of atrazine at 2 WAP.
The relative abundance of Tithonia at 8-12 WAP was between
96.8 and 99.5% and this indicates that the plant could be a dominant weed in a
