This study proceeded in the spring of 2022 to assess the efficiency of Metribuzin herbicide alone and combined with some agricultural methods, such as mulching and hoeing, to control potato weeds. The effect of Metribuzin at a rate of 400 g ha-1 with mulching reduced the total weed density to 19.0 plants m-2, similar to Metribuzin at a rate of 800 g ha-1 (16.0 plants m-2). The efficiency of Metribuzin herbicide at 400 g ha-1 combined with one or two hoeings reduced the number of weed densities by 19.3 and 10.6 plants m-2 for one hoeing and two hoeings, respectively. The effect positively manifested in plant heights, the number of leaves, the foliage dry weight, and its reflection on the potato yield weight.
Potato (Solanum tuberosum L.), Solanaceae, weed management, Metribuzin, mulching, hoeing, weed population
Metribuzin herbicide treatment at a rate of 800 g ha-1 alone or in combination with mulching or hoeing was effective in controlling weeds. It manifested in the yield and chemical properties of the potato. Integration between mulching or hoeing with 400 g ha-1 of Metribuzin significantly controlled the weeds and the studied potato traits.
