摘要

本试验于2021 - 2022年农作季在北阿坎德邦潘特纳格尔G.B.潘特农业技术大学进行,旨在评价罐式混合除草剂对杂草和玉米(Zea mays L.)的影响,以确定玉米除草剂的最佳用量、施用时间和组合。综上所述,在无杂草条件下,通过顺序或槽式混合施用阿特拉津与替博曲酮或topramezone,可以有效地减少杂草,提高粮食产量。农民应采用topramezone (25.2 g a.i./公顷)和tembotrione (120 g a.i./公顷)与减少剂量的阿特拉津(0.75 kg a.i./公顷)的罐式混合处理,因为它不仅有效地清除杂草,而且还为玉米生长提供了更好的环境,为农民提供了高利润。它还降低了人工除草和分别喷洒阿特拉津的剂量和费用。

Effects of sequential and combined application of tank-mix herbicides on weed growth and productivity of maize (Zea mays)
The field experiment was conducted at G.B. Pant University of Agriculture and Technology, Pantnagar, Uttarakhand during kharif season 2021–22 to evaluate the effects of tank-mix herbicides on weeds and maize (Zea mays L.) in order to determine the optimum dosage, application time and combinations of herbicides for maize. Based on the findings, it could be concluded that weed-free conditions are just as effective as atrazine applied with tembotrione or topramezone through sequential or tank mix application for reducing weeds effectively and increasing grain yield. Tank mix treatments of topramezone (25.2 g a.i./ha) and tembotrione (120 g a.i./ha) with reduced dose of atrazine (0.75 kg a.i./ha) should be employed by farmers since it not only removes weeds effectively but, also offers a better environment for maize to grow providing high profits for farmers. It also lowers the dose and expenses involved in manual weeding and spraying atrazine separately.
