A field experiment was carried out at Annamalai University, Annamalai Nagar of Chidambaram taluk, Cuddalore district, Tamil Nadu during January -April 2023 to study the "Integrated weed management of irrigated groundnut (Arachis hypogaea L.)". The study included ten treatments, a randomised block design, and three replications. The treatments that produced the highest values of yield components at harvest, such as kernel yield, pod yield and growth parameters were the two hand weeding treatments on 20 and 40 DAS (T2) and it was on par with the pre-emergence application of pendimethalin 1.0 kg a.i. ha -1 at 3 DAS followed by the post-emergence application of quizalofop 100 g a.i. ha -1 at 21 DAS (T4). This was followed by (T6) Groundnut shell cover mulch @ 2000 kg ha -1 followed by Early Post-emergence (Sodium acifluorfen) 900 g a.i. ha -1 on 15 DAS. The unweeded control (T1) had the largest biomass and weed counts, which led to an extremely low grain yield. This experiment observed that, twice hand weeding on 20 and 40 DAS (T2) and it was on par with Pre emergence application of pendimethalin 1.0 kg a.i. ha -1 at 3 DAS followed by post emergence application of quizalofop 100 g a.i. ha -1 at 21 DAS (T4) was the most effective weed control technique, increasing yield production and growth and reduce the nutrient uptake by weeds and higher economic returns from irrigated groundnut.

“…Pre-emergence (PE) herbicides, viz. pendimethalin (Patel et al 2013) and oxyfluorfen (Ramalingam et al 2013) and post-emergence (POE) herbicides, viz. imazethapyr (Kalhapure 2013) quizalofop-ethyl (Samant et al 2014) were found very effective in controlling weeds, higher crop yield and increased income in different parts of the country.…”

Field experiment was conducted on medium black calcareous clayey soil at Junagadh Agricultural University, Junagadh during two consecutive seasons of 2013 and 2014 to study the influence of different weed management practices on productivity and economics of Kharif groundnut (cv. GG-20). Higher weed control efficiency (82.6%), herbicide efficiency index (74.1%), lower weed index (5.1%) and lesser monocot weed density were recorded with pendimethalin 0.9 kg/ha pre-emergence application (PE) followed by (fb) intercultivation (IC) and hand weeding (HW) at 40-45 days after seeding (DAS). Weed density of most dominated sedge weed species at 30 DAS, 60 DAS and at harvest were significantly lowered with application of pendimethalin 0.9 kg/ha PE fb imazethapyr 75 g/ha as postemergence application (POE) at 25-30 DAS compared to other herbicides, which were 92.7, 93.5 and 93.0% less over the unweeded control, respectively. The same treatment also recorded the lowest weed dry biomass at harvest. Besides weed free, significantly the higher pod yield (1.75 t/ha) and net return (4 0,657/ha) and B: C ratio (2.38) were recorded with application of pendimethalin 0.9 kg/ha PE fb IC and HW at 40-45 DAS. No phytotoxicity symptoms has been observed with any of the herbicides applied to Kharif groundnut.

“…The first four to eight weeks after sowing are critical for weed management, as this period greatly influences crop growth [2]. Studies suggest that weed interference can result in significant losses in groundnut production, ranging from 15 to 75 per cent nationally [3].…”

A field experiment was conducted at Agricultural Research Station, Kumta, Uttara Kannada district during the rabi-summer season of 2016-17 to investigate the Bio-efficacy of herbicides on weed density, weed control efficiency, productivity and groundnut quality in coastal zone of Karnataka under rice-groundnut system. The experiment followed a RBD with nine treatments out of which six treatments involved the pre-emergence application of herbicides followed by either hand weeding or early post-emergence application, along with control treatments. The results indicated that the pre-emergence application of pendimethalin 30% E.C. (1.5 kg ha-1), followed by one hand weeding at 25 days after sowing (DAS), resulted in significantly reduced total weed density and weed dry matter. This treatment also demonstrated higher weed control efficiency and lower weed index. Moreover, it led to increased pod yield, kernel yield and improved quality of groundnut compared to other treatments.
