“…This is crucial as prolonged weed pressure can severely impact crop yield. The Weed Control Efficiency (WCE) and Herbicide Efficiency Index (HEI) highlight that the Manual Control and S-Metolachlor + Pendimethalin maintained high efficiency, suggesting they were successful in controlling weeds without adversely affecting the soybean crop [60]. However, herbicides such as S-Metolachlor + Atrazine + Mesotrione, Topramezone, Mesosulfuron-methyl + Iodosulfuron-methyl sodium and Mesotrione + Atrazine had no WCE or HEI data, which indicates total crop failure due to herbicide damage.…”

Soybean (Glycine max L.) is a vital leguminous crop known for its rich nutritional profile, includ-ing high protein and oil content, making it a valuable resource in global agriculture and human nutrition. In Pakistan due to regulatory issues non-GMO soybean is grown therefore, the universal herbicide control method is not applicable. Similarly, for other crops, specific herbicides are avail-able but for soybean no crop specific herbicide is present. A comprehensive study was conducted over two growing seasons, in 2022 and 2023, at Agronomic Research Farm University of Agri-culture Faisalabad. The research involved 16 different treatments, including both six pre-emergence and eight post-emergence herbicides as well as a control group and weedy check. Findings of this study showed that critical importance of weed management in soybean cultiva-tion, as unchecked weed infestation can lead to substantial yield losses. Among the pre-emergence herbicide S-Metolachlor + Pendimethalin performed best and showed higher plant height (54.33 cm & 53.67 cm), 100 grain weight (11.57 g & 12 g), seed yield plant-1 (13.07 g and 12.87 g), lower Susceptibility Index (10%), higher weed control percentage (91.21% & 95.65%) higher weed con-trol efficiency (92.02% & 93.43%), herbicide efficiency index (27.54% & 32.48%) and lower weed index (18.16% & 21.70%) during 2022 and 2023 respectively. However, in post emergence herbi-cide the Fluizefop-p-butyl is most effective herbicide due to less crop injury 10% Susceptibility In-dex, higher plant height (42.67 cm & 44 cm), whole plant weight (93.33 g & 95 g), 100-grain weight (11.40 g & 11.77 g), seed yield plant-1 (12.87 g & 13.13 g), higher weed control percentage (91.12% & 91.03%) higher weed control efficiency (89.73% & 92.36%, herbicide efficiency index (21.18% & 30.41%) and lower weed index (19.42% & 20.08%) in both 2022 and 2023 respectively. Notably, herbicides such as S-Metolachlor + Atrazine + Mesotrione, Topramezone, Mesosulfu-ron-methyl + Iodosulfuron-methyl sodium and Mesotrione + Atrazine led to complete plant mor-tality, resulting lethal to soybean. The findings of this study support the hypothesis that screened the best suitable herbicides with less plant injury, and higher efficiency index. So, it is recom-mended that the application of S-Metolachlor + Pendimethalin as PRE and Fluizefop-p-butyl as POST showed the least injury and best weed control results with higher grain yield.

“…Sole application of herbicide as pre emergence fails to control subsequent flushes of weeds. So, there is need to apply pre-and post emergence herbicides in a sequential manner to reduce weed menace and keep the crop free from weed competition during entire critical period of crop growth (Tuti and Das, 2011). Energy budgeting of weed management is also important because energy and economics are mutually dependent.…”

during rabi 2020-21. The experiment consisted of ten treatments laid out in randomized block design replicated thrice. The treatments comprised of diclosulam 84% WDG 26 g ha -1 PE fb intercultivation at 20 DAS, imazethapyr 2% EC + pendimethalin 30% EC 960 g ha -1 PE fb intercultivation at 20 DAS, pyroxasulfone 85 % WDG 127.5 g ha -1 PE fb intercultivation at 20 DAS, propaquizafop 2.5% + imazethapyr 3.75% w/w ME 125 g ha -1 PoE fb intercultivation at 40 DAS, imazethapyr 35% + imazamox 35% WG 70 g ha -1 PoE fb intercultivation at 40 DAS, sodium acifluorfen 16.5% EC + clodinafop propargyl 8% EC 250 g ha -1 PoE fb intercultivation at 40 DAS, imazethapyr 10% SL 100 g ha -1 PoE fb intercultivation at 40 DAS, intercultivation (20 and 40 DAS), intercultivation fb hand weeding (20 and 40 DAS) (Weed-free) and unweeded control. Among all the weed management practices, maximum energy input was required for inter cultivation fb hand weeding at 20 and 40 DAS. Highest pod energy output (EOp), total energy output (EOt) and net energy was observed with inter cultivation fb hand weeding at 20 and 40 DAS and was on par with diclosulam 26 g ha -1 PE fb intercultivation at 20 DAS and sodium acifluorfen + clodinafop propargyl at 250 g ha -1 PoE fb intercultivation at 40 DAS. Significantly highest EUE of pods, total output EUE, energy productivity of pods and total output energy productivity was recorded in diclosulam 26 g ha -1 PE fb intercultivation at 20 DAS and this was at par with imazethapyr + pendimethalin 60 g ha -1 PE fb intercultivation at 20 DAS.

A field experiment was conducted at the Rajasthan College of Agriculture, MPUAT, Udaipur during Kharif season 2015 and 2016 to adjudge the efficacy of different herbicide and herbicide mixtures against weeds in soybean. Monocot weeds were predominant (55.15%) in the experimental field compared with dicot weeds (44.85%). However, Echinochloa colona (41.56%) and Trianthema portulacastrum (33.16%) were predominant in soybean but, other weeds (Cyperus rotundus, Cynodon dactylon, Commelina benghalensis, Digera arvensis, Amaranthus viridis, Physalis minima, Corchorus spp.) were also present at 60 DAS. Among different weed control treatments, post-emergence and tank mix combination of propaquizafop + imazethapyr (75+75 g ha-1) and imazethapyr + quizalofop-ethyl (75+60 g ha-1) at 21 DAS were most effective in respect of reducing weed density, weed biomass, nutrient removal by weed and promote yield attributes and yield and quality of soybean as compared to rest of weed control treatment.
