“…The highest dry matter production in these treatments might be due to effective control of all category of weeds during active crop growth period, which might have increased the plant height, LAI and number of branches plant -1 , which in turn resulted in higher dry matter production. These results are in agreement with that of Kalhapure et al (2013) [6] . Further timely and effective control of weeds might have facilitated the better availability of moisture, nutrients and solar radiation to the crop plants, thereby increased chlorophyll content, photosynthetic rate and nitrate reductase activity, leading to higher supply of carbohydrates, which resulted in increased dry matter production (Channappagoudar et al 2008) [2] .…”

“…The higher pod yield in these treatments was due to minimum crop-weed competition and effective control of broad spectrum of weeds for a longer period in the initial stage of crop and provided congenial environment for growth and development as evident from increase in plant height, leaf area index and dry matter production, improvement in growth parameters which inturn increases the yield attributes like number of filled pods plant -1 , hundred pod and kernel weight as well as shelling percentage and ultimately the pod yield. These results were in line with the findings of Kalhapure et al (2013) [6] and Sandil et al (2015) [11] . Weed free environment during the critical stages of the groundnut facilitated better peg penetration which tends to increase the number of pods plant -1 and pod yield (Dutta et al, 2005) [4] .…”

Background:The main problems limiting production of groundnut are poor cultural practices as well as inadequate weed management. Besides competing for nutrients, soil moisture, sunlight, weeds inhibit pegging, pod development in groundnut and also interfere with harvest. Manual weeding, an age old practice for weed control in this crop is very laborious, time consuming and expensive, most importantly when there is dearth of manpower. In groundnut, chemical weed control has been found to be easier; less time consuming and more cost effective and efficient in reducing weed menace compared to hand weeding. By integrating man, mechanical and chemicals we can achieve better yield and also can retain the soil health. Hence the objective of this experiment was to study the effect of integrated weed management practices on the growth and yield of groundnut. Methods: In this experiment during 2020-21, different weed management practices and their effect on growth parameters, yield attributes and yield of groundnut at College of Agriculture, Professor Jayashankar Telangana State Agricultural University, Hyderabad were surveyed. The experiment consisted of ten treatments laid out in randomised block design replicated thrice. Result: Among the different weed management practices growth parameters i.e., plant height, leaf area index and dry matter production, yield attributes i.e., number of pods per plant, filled pods per plant, hundred pod weight and hundred kernel weight and yield were significantly higher with intercultivation fb hand weeding at 20 and 40 DAS. Among herbicides, diclosulam 26 g ha -1 PE fb intercultivation at 20 DAS, pendimethalin + imazethapyr (pre-mix) 960 g ha -1 fb intercultivation at 20 DAS and sodium acifluorfen + clodinafop propargyl 250 g ha -1 PoE fb intercultivation at 40 DAS were superior to the all other treatments.

“…Common weeds found in groundnut are Digitaria sanguinalis, Cynodon dactylon and Cyperus rotundus (Ghosh et al, 2000). The yield of groundnut was reduced by 13 to 80 %due to weed infestation in India (Kalhapure et al, 2013). Similarly, crop yield loss up to 50-70 % was noticed in Nepal (Bhattarai et al, 2021) that increased the cost of cultivation as timely weeding is required increasing the labor charges Kalaiselvan et al (1991) stated that weed free condition from 15 to 40 days after sowing was essential for getting maximum yield.…”

Weeds are the most important biotic constraints to groundnut production in Nepal. They hinder the plant growth and increase the cost of production. A field based study was conducted from June, 2022 to December, 2022 at Oilseed Research Program, Sarlahi, Nepal to study the effect of mulch on the productivity of groundnut. The experiment was laid out in randomized complete block design with 7 treatments viz., rice husk, rice straw, black polythene sheet, Lantana camara, living mulch, sawdust and control in three replications. The fertilizer dose used for groundnut was 20:40:20 NPK kg per hectare. The pod yield in rice husk mulch and living mulch treatments were significantly higher (2.07 and 1.84 tons per hectare, respectively) whereas the lowest yield (0.83 tons/hectare) was observed in plot with no treatment). Lower weed infestation with weed biomass 0.046 tons/ha for narrow leaf weeds and 0.021 tons/ha for broad leaf weeds was observed in L. camara mulching. Rice husk mulching produced significantly higher number of pods (29 pods per plant) with the highest benefit cost ratio (1.15) whereas black polythene mulching produced lower number of pods (23 pods per plant) with lowest benefit cost ratio (-0.33). Conclusively, the study's finding suggests that rice husk can be used as a mulching material to increase the productivity of groundnut.

“…Ayomide [11] reported a 51 % reduction in pod yield of groundnut when weed growth was unrestricted throughout the life cycle of the crop in the northern guinea savannah of Nigeria. According to Devi Dayal [12]; Jat et al [13], the critical period of weed interference in groundnut is between 3-7 WAP. Weeds compete with crops for light, water and nutrient ions in the soil.…”

To quantify the efficacy of effective weed control methods and spacing of groundnut on soil microbiological properties, a field experiment was conducted between 2009 and 2010 at the Teaching and Research Farm of the University of Agriculture, Abeokuta, a sub-humid region of southwestern Nigeria. Treatments were five levels of weed control (codal gold 1.6 kg a.i/ha, codal gold 1.6 kg a.i/ha + hoe weeding, codal gold 2.4 kg a.i/ha, hoe weeding and a control (weedy check); two levels of spacing (15 cm and 25 cm) and eight levels of weeding intervals on soil microbial biomass, nodulation, the biomass of root and shoot as well as yield of groundnut in a split-plot design fitted into a randomized complete block design. The results indicated that both levels of spacing have no significant effect on the soil microbiological parameters, groundnut biomass production, nodulation and yield. So, the levels of weed control have no significant effect on groundnut biomass production and nodulation but showed a significant effect on microbial biomass carbon (MBC), microbial biomass nitrogen (MBN), total fungal count, pod count and pod weight of groundnut with plots kept weedy throughout the experiment at 25 cm intra row spacing having 34 % MBC more than plots kept weed free throughout the experiment at the same spacing.
