“…In the weed control treatments, however, there were sufficient resources for the maize crop plants. Analogous results were reported by Mahadi et al [31] who showed that some herbicides applied to maize increased the plant height of maize more than the weedy check. Similarly, Pre-emergence application of Lunar 537.5 SE achieved numerically the maximum number of rows per ear (15.47) and thousand kernel weight (400.67 gm.…”

“…The maximum weed density achieved in weedy check plots might be due to lack of any weed management practices which rendered the chance for better weed emergence, growth and development which in turn leads less competition and more time to explore the nutrients from the soil and crop plants by the weeds. Analogous results were reported by Mahadi et al [31] who noted that a weedy check plots produced the highest weed cover score and dry weight at harvest while herbicides significantly lowered weed density. The minimum weed density observed in two times hand weeding and pre-emergence herbicides treated plots could be due to the sufficient and successful weed control achieved by these practices.…”

A field experiment was conducted to evaluate efficacy of pre-emergence herbicides against major weeds in maize at Bako during the main rainy season of 2016/17. The trial was laid out in randomized complete block design (RCBD) with three replication, and consisted of five treatments including pre-emergence application of Lunar 537.5 SE at 3L/ha, Venus 500 SC at 6L/ha and Prima gram dual Gold 660sc at 3 L/ha, and two times hand weeding at 25 and 40 DAS and weedy check for comparison. Application treatments boosted maize grain yield over weedy check plots there by reducing weed infestation. Analysis of variance showed statistically significance difference (P < 0.01) for total weed density (m -2 ) and dry weight (gm.-2 ). Significantly the minimum density (8.5 m -2 ) was observed in plots treated two times hand weeding which was statistically similar with evaluated herbicides. In contrary, the highest (39.1 m -2 ) was observed in weedy check plots. All the herbicide treatments provided significant control of weeds causing significant reduction in density of target weed flora and also significantly improved the grain yield in comparison with the weedy check. However, no crop injury was observed in any of the herbicide treatments. The maximum grain yield (57.57 qt ha -1 ) was obtained from Lunar 537.5 SE at 3L/ha followed by two times hand weeding (57.08 qt ha ) was from weedy check plots. In general application preemergence herbicides effectively control weeds in maize and reduce yield losses. Thus, the newly tested pre-emergence herbicides (Lunar 537.5 SE at 3L/ha and Venus 500 SC at 6L/ha) alone could be option to major weeds and increase maize grain yield.

This study was aimed to assess weed species diversity and composition in cassava monoculture at Crop and Soil Sciences Department research field, Kwame Nkrumah University of Science and Technology, Kumasi. The experimental design was a randomised complete block design and replicated four times. The treatment factors were six weeding methods (Butachlor (4L/ha) + 2 hoe-weedings, Terbulor (4L/ha) + 2 hoe-weedings, three hoe weedings, three cutlass weedings, weed-free and weedy check) and two cassava varieties (Ampong and Dokuduade). Twenty-five weed species belonging to twelve different families were recorded and overall weed flora was composed of 80% broad-leaved weeds, 12% kinds of grass and 8% sedges. The results revealed that Cyperus rotundus, Spigelia anthelma and Panicum maximum were the three dominant and major weed species. Panicum maximum recorded the highest relative frequency while Spigelia anthelma and Cyperus rotundus showed higher values of relative density, relative abundance and important value index under both varieties.

“…Hence the findings from this study suggests that weeds continually need a long-term management practices to tackle its problem. Mahadi et al (2007) reported that a weedy check treatment produced the highest weed cover score and weed dry weight at harvest. Also, increase in weed density up till ripeness of crop evidently shows that weed seeds germinated throughout the growth period of maize.…”

A two-year (2017 and 2018) field trials was conducted in the School of Agriculture, Njala University, Sierra Leone, to evaluate weed management practices on weed dynamics and productivity of maize. The experimental trials were laid out in a randomized complete block design (RCBD) with three replications. The treatment combinations comprised of weedy check (Control), two hoe weeding at 4 and 8 weeks after planting (WAP), Double force ® at 4 L ha -1 plus one hoe weeding at 8 WAP, Gliricidia sepium leaves mulch at 40 kg m -2 plus one hoe weeding at 8 WAP, weed-free check and Atrazine 500 SC at 3 L ha -1 plus one hoe weeding at 8 WAP. The results showed that growth and yield physiognomies differ significantly (P<0.05) among weed control practices across both years. The weed-free check treatment recorded the highest growth and yield physiognomies with respect to reduced weed density and increased weed control efficiency followed by herbicidal treatments, while weedy check had the lowest growth and yield attributes across both years. Nonetheless weed-free check required lot of labour force which was not economical to the farmer's point of judgment. Thus, Double force ® at 4 L ha -1 plus one hoe weeding at 8 WAP proved to be better in controlling weeds, increasing crop yield and economical compared with other weed management practices. Hence Double force ® at 4 L ha -1 plus one hoe weeding at 8 WAP was recommended as a pre-emergence herbicide in maize production for effective and environmentally friendly weed control method.
