Chickpea (Cicer arietinum L.) is a dominant pulse crop in the world for its climate resilience and nutritional values. Weed infestation causes a significant yield loss in chickpea and jeopardize in realizing the potential yield across regions. Pendimethalin as pre-emergence (PRE) is the ruling herbicide, however, post-emergence (POST) herbicides are limited in this crop particularly for managing broad-leaved weeds and higher yield gain. We assessed the impact of POST herbicides available in different crops on weed phytotoxicity, crop selectivity and yield performance in chickpea on sandy-loam soil of Kanpur, India. The experiment was undertaken for two consecutive years (2016-17 and 2017-18) comprising nine herbicides, besides unweeded control (UWC) and weed-free check (WFC). Among the herbicides tested, halosulfuron-methyl 70 g a.i. ha⁻¹ and tembotrione 100 g a.i. ha⁻¹ showed the maximum phytotoxicity scale of 5-10 on chickpea. Clodinafop-propargyl + sodium-acifluorfen 122.5 g a.i. ha⁻¹ and imazethapyr + imazamox 70 g a.i. ha⁻¹ had a recoverable phytotoxicity (scale 3–5) on chickpea. Topramezone 20.6 g a.i. ha⁻¹ at 25 days after sowing (DAS) resulted in higher phytotoxicity on weeds (toxicity scale of 7–10) without any phytotoxicity on chickpea. It significantly controlled the dominant broad-leaved weeds: Chenopodium album L., Lepidium didymum L., Spergula arvensis L., Medicago polymorpha L. and Fumaria parviflora Lam. compared to the remaining herbicides. Topramezone reduced total weed density by 68-70% and 48–51% (P ≤ 0.05) at 45 and 95 DAS compared with UWC, respectively. Therefore, this herbicide had higher (P ≤ 0.05) weed control efficiency in both years (89.8% in 2016-17 and 76.5% in 2017-18) than remaining treatments. Topramezone increased 15.3-19.6% chickpea seed yield than the recommended herbicide pendimethalin 1000 g a.i. ha⁻¹ - quizalofop-p-ethyl 100 g a.i. ha⁻¹ without affecting the nodulation and fluorescein diacetate activity. The UWC resulted in 64% (mean of two years) yield loss compared to the WFC in chickpea. Importantly, topramezone gave comparable yield with WFC. Hence, topramezone can be safely used in chickpea for managing broad-leaved weeds and realizing higher productivity.

鹰嘴豆 ( Cicer arietinum L.) 因其气候适应性和营养价值而成为世界上的主要豆类作物。杂草侵扰导致鹰嘴豆产量显着下降，并危及跨地区实现潜在产量。二甲戊乐灵为预-出现（PRE）是执政党除草剂，然而，后-出苗（POST）除草剂在这种作物的限制特别是对于管理广泛-阔叶杂草，产量较高的增益。我们评估了杂草药害，作物选择性和产量表现在不同作物可用POST除草剂的鹰嘴豆沙上的冲击-印度坎普尔的壤土。实验进行了连续两年（2016 -17 和 2017 - 18) 包括九种除草剂，除了无杂草控制 (UWC) 和无杂草检查 (WFC)。在测试的除草剂中，甲基卤嘧磺隆70 g ai ha ^-1和 tembotrione 100 g ai ha ^-1对鹰嘴豆的最大植物毒性范围为 5 - 10。炔草酯 + 氟锁草醚钠 122.5 g ai ha ^-1和咪草烟 + 咪草啶酸 70 g ai ha ^-1对鹰嘴豆具有可恢复的植物毒性（3-5 级）。Topramezone 20.6 g ai ha ^-1在播种后 25 天 (DAS) 对杂草产生更高的植物毒性（毒性等级为 7-10），而对鹰嘴豆没有任何植物毒性。它显着控制了占主导地位的广泛-有叶杂草：Chenopodium album L.、Lepidium didymum L.、Spergula arvensis L.、Medicago polymorpha L. 和Fumaria parviflora Lam。与其余除草剂相比。 与 UWC 相比，Topramezone 在 45 和 95 DAS 时分别将总杂草密度降低了 68 - 70% 和 48 - 51% ( P ≤ 0.05)。因此，该除草剂 在两个年份（2016 - 17年为 89.8 %，2017 - 18 年为76.5% ）的杂草控制效率均高于（P ≤ 0.05）。Topramezone 增加 15.3 -鹰嘴豆种子产量比推荐的除草剂二甲戊灵 1000 g ai ha ^-1 - quizalofop - p -乙基 100 g ai ha ^{-1 高}19.6%，而不影响结瘤和荧光素二乙酸酯活性。与 WFC 相比，UWC 导致鹰嘴豆产量下降 64%（两年的平均值）。重要的是，topramezone 的产量与 WFC 相当。因此，苯吡唑草可以安全地在鹰嘴豆用于广泛的管理-阔叶杂草，实现更高的生产率。
