Abstract:
Background and Objective: An experiment was installed at Kasapa farm during the 2013-2014 cultural season in aim to assess the effects of sowing dates and glyphosate doses on the behavior of common bean. Materials and Methods: The essay was installed according to a split plot device, the main factor was constituted of planting dates and glyphosate doses secondary factor. The effects of three sowing dates (25th January, 5th February and 15th February) and four doses of glyphosate (1.5, 3, 4.5 and 6 L ha–1) on common bean behavior were assessed. Results: The analysis of variance showed the lack of interaction between herbicides doses and sowing dates on all common bean growth and production parameters. However, Tukey HSD test revealed the effects of planting date on plant size. On first sowing date (25th January), the number of pods per plant was similar to plots sown on 5th and 15th February. Moreover, the highest grain yield (2.03 t ha–1) was obtained in plots sown on 5th February. Conclusion: This study showed the influence of sowing dates on weed flora. The study also proved that four species of weeds, Cyperus rotundus, Ageratum conyzoides, Ageratum houstonianum and Spilanthes acmella were indifferent and resistant to two weed management modes (sowing date optimization and glyphosate application).
