“…Patel et al [9] observed that significantly highest pod and haulm yield of groundnut were produced in weed free treatment followed by pendimethalin + imazethapyr and inter-culturing + hand weeding treatments. Similar results were also reported by Bhale et al [12] and Kalhapure et al [13]. Under the present investigation, existence of high positive and significant correlation between pod yield and plant dry matter accumulation at harvest, number of pods/plant, pod yield/plant with respective values of r = 0.996, 0.984 and 0.982 (Fig.…”

Groundnut (Arachis hypogaea L.) is a significant oilseed crop extensively cultivated throughout India. Despite the availability of high-yielding varieties and modern agricultural practices, the productivity of groundnut remains relatively low. Weed infestation is identified as one of the primary factors contributing to reduced productivity among various unstable factors. During the early stages of growth, groundnut exhibits slow initial growth, making it a poor competitor against weeds. To enhance growth and yield, effective weed management strategies are crucial. To address this, a field experiment was conducted during the kharif season of 2019 at Agricultural Research Station, Mandor, Agriculture University, Jodhpur, Rajasthan. The experiment consisted of thirteen treatments involving pre- and post-emergence herbicides, including weedy check and weed-free check, with three replications in a randomized block design. Results revealed that weed-free treatment recorded significantly lower weed density, weed dry matter and higher weed control efficacy, ultimately leading to improved growth, yield attributes, and overall yield of groundnut as compared to weedy check. Among weed control measures, Pendimethalin + imazethapyr @ 1.0 kg /ha (PE) + one manual weeding at 30 DAS (Days After Sowing) recorded significantly lower weed density, weeds dry matter and increased weed control efficiency, growth parameters (plant height and dry matter accumulation), yield attributes (number of pods /plant, pod yield /plant, number of kernels /pod and seed index) and yield (pod yield, kernel yield, haulm yield, biological yield, harvest index, and shelling out-turn), followed by pendimethalin @ 1.0 kg /ha (PE) + imazethapyr @ 75 g /ha at 20 DAS. Economically, these treatments recorded significantly higher gross returns, net returns and B: C ratio, proving to be more profitable than other herbicide applications used in the groundnut crop.

“…In herbicidal treatments, pendimethalin @ 0.75 kg ha -1 (PE) effectively reduced the total weed density at all stages of the crop growth, which was due to ability of pendimethalin to inhibit root and shoot growth of grasses. These findings corroborate the results of (Bhale et al, 2012;Kalaichelvi et al, 2015;Kirde et al, 2019 andDamor et al, 2019). Since hand weeding is cumbersome and also labour intensive, use of twin wheel hoe at 20 DAS fb hand weeding at 40 DAS was economic as compared to other treatments.…”

Background: Groundnut or peanut (Arachis hypogaea L.) is known as the “King of Oilseeds” which belongs to family Fabaceae (Leguminosae). It is highly susceptible to weed infestation because of its slow initial growth up to 40 DAS and small foliage cover. However, study on use of mechanical weed control methods with different fertility regimes for improving the productivity of groundnut was limited. Therefore, the objective of this study was to find a suitable method for optimising the productivity of groundnut. Methods: A field experiment was conducted at Odisha University of Agriculture and Technology, Bhubaneswar for two consecutive years of 2020 and 2021. The field experiment comprised 16 treatment combinations of four weed management practices and four fertility levels. The weed management practice included W1-Pre-emergence (PE) application of pendimethalin @ 0.75 kg ha-1, W2-Pre-emergence (PE) application of pretilachlor @ 0.5 kg ha-1, W3-Manual weeding (20 and 40 DAS), W4-Twin wheel hoe at 20 DAS followed by (fb) hand weeding at 40 DAS and four fertility levels includes T1-100% RDF (20:40:40) (N: P205: K2O kg ha-1), T2- 75% RDF + 5 tonnes FYM ha-1, T3- 50% RDF + 10 tonnes FYM ha-1, T4- without fertilizer + without FYM. Result: Amongst the weed management practices, use of twin wheel hoe at 20 DAS followed by hand weeding at 40 DAS significantly reduced the weed density, weed dry weight, weed index and recorded the highest weed control efficiency (69.8%). Highest weed index (32.9) was recorded with the application of pretilachlor @ 0.5 kg ha-1 (PE), which was followed by weed index of (28.5) with application of pendimethalin @ 0.75 kg ha-1 (PE). The fertilizer management practice with application of 50% RDF + 10 tonnes FYM ha-1 gave the highest yield and considerably reduced the total weed density, weed dry weight and recorded the maximum weed control efficiency (71.8 % at harvest). We suggest that weed management with twin wheel hoe at 20 DAS followed by hand weeding at 40 DAS along with application of 50% RDF + 10 tonnes FYM ha-1 as the most effective strategy for controlling the weed menace in groundnut with the highest weed control efficiency.

“…The lower pod yield (1012 kg ha -1 ) was obtained under unweeded control (T 1 ). The reason for this might be that hand weeding promotes soil pulverisation, improved nodulation, root proliferation, and more pod forms, all of which increase pod production as reported by (Bhale et al, 2012) [3] . Applying herbicides early in crop growth minimises the number of weeds, allowing for improved crop growth and peg initiation and development during important groundnut growth phases, which has a synergistic effect on production qualities reported by (Mulik et al, 2010) [7] and (Wani et al, 2010) [14] .…”

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.
