Effect of integrated weed management practices on weed dynamics and economic performance of potato crop in northern plains

Acknowledging that effective weed management is essential for ensuring healthy crop growth and maximizing yields, a field experiment was undertaken during the Rabi season of 2022 at the Research Farm of the Department of Vegetable Science, CCSHAU, Hisar, Haryana. The study aimed to evaluate the performance of the potato variety ‘Kufri Bahar’ under thirteen different weed control treatment combinations. The analysis of collected data demonstrated that the choice of weed management strategy had a significant influence on multiple yield and weed-related parameters, underscoring the importance of integrated weed control practices in optimizing potato production. The results obtained were recorded and observed that at 25 DAP highest weed density and maximum dry matter accumulation of weeds were recorded in the treatments T13, T11 and T8. The weed control efficiency among different weed control treatments was found maximum in T6 followed by T3. Weed index was found minimum in T12 which was followed by T11, T6 and T3. The highest net returns was recorded under treatment T12, followed by T11, T6 and T3.
