摘要
通过2020-21和2021-22年的田间试验,研究了不同出苗后除草剂对鹰嘴豆广谱杂草治理的效果。试验采用随机分组设计,共8个处理,重复3次。处理包括topramezone 20.6 g a.i. ha-1 (14 DAS)、topramezone 20.6 g a.i. ha-1 (21 DAS)、topramezone 25.7 g a.i. ha-1 (14 DAS)、topramezone 25.7 g a.i. ha-1 (21 DAS)、quizalofop-p-ethyl 100 g a.i. ha-1 (21 DAS)、除草控制、无杂草检查(手动)和imazethapyr +手动杂草控制(MWC)。在不同的除草剂处理中,20.6 g a.i. ha-1处理的种子产量最高(1377 kg ha-1),其次是20.6 g a.i. ha-1处理的杂草防治效率最高(1265 kg ha-1),并且在2020-21年期间取得了较高的收益(45659 ha-1)和B: C比(2.73)。
Bio-efficacy of different POE herbicides for broad spectrum weeds management in chickpea (Cicer arietinum L.)
A field experiment was conducted during 2020-21 and 2021-22 to study the effect of different post-emergence (POE) herbicides for broad spectrum weed management in chickpea. The experiment was laid out in a randomized block design with eight treatments and replicated thrice. Treatments comprises topramezone 20.6 g a.i. ha-1 at 14 DAS, topramezone 20.6 g a.i. ha-1 at 21 DAS, topramezone 25.7 g a.i. ha-1 at 14 DAS, topramezone 25.7 g a.i. ha-1 at 21 DAS, quizalofop-p-ethyl 100 g a.i. ha-1 at 21 DAS, unweeded control, weed free check (manual) and imazethapyr + manual weed control (MWC). Among the different herbicidal treatments, topramezone 20.6 g a.i. ha-1 at 21 DAS significantly higher seed yield (1377 kg ha-1) followed by topramezone 20.6 g a.i. ha-1 at 21 DAS (1265 kg ha-1), highest weed control efficiency and also recorded higher return (₹ 45,659 ha-1 ) and B: C ratio (2.73) during 2020-21.
