“…The probable reasons for obtaining lowest weed population under herbicides tried might be due to pre and post emergence application of herbicides resulted in better weed management during initial and later growth stages of crop due to their differed ability to control weeds as well as smothering effect of crop as lesser weed competition faced by groundnut crop. Similar results were also reported by Adhikary et al (2016) and Sahoo et al (2017).…”

Background: Agriculture sector is vital for food and nutritional security of the nation. Contrary to great stride in cereals and millets production during last few decades, desired rise in production of oilseeds has yet to be achieved though India has 14 and 9 per cent of global acreage and production.Methods: The present investigation was conducted during kharif seasons of 2016 and 2017, at Instructional farm, MPUAT, Udaipur to access the effect of different pre - post herbicides for weed control in groundnut under phosphorus application. This experiment was operated with six weed management practices and four phosphorus levels thus, 30 treatment combinations; all were evaluated in split-plot design with three replications.Result: Our investigations results revealed that herbicidal treatments as well as weed free check significantly control weed population and recorded the highest values of N, P, K concentration in weeds, kernel, biological yields and total chlorophyll content over weedy check while, significantly maximum N, P, K uptake and soil available phosphorus were noted under weedy check over rest of the treatments. Further, the results also showed that application of phosphorus exhibit significant increase in nutrient concentration and their uptake by weeds, kernel, biological yields, total chlorophyll content and soil available phosphorus over control during the course of investigation.

“…In all, pendimenthalin non-expired + one hand weeding at 6 weeks after sowing and two hand weeding at 3 and 6 WAS significantly increased the growth parameters compared to other treatments. The result obtained in this study aligned with the study of Adhikary et al (2016), who reported that application of herbicide affect the growth parameters of groundnut treated with different herbicides postand pre-emergence.…”

The use of expired herbicides to suppress weeds growth is becoming prevalent among farmers. Hence the need to investigate and compare the effect of expired and non-expired pendimethalin and hand weeding on weed suppression, growth, yield and composition of groundnut. The experiment was carried out during therainy season in 2020. It consisted of seven weed control treatments. These were sole pendimethalin non-expired (T1), pendimethalin non-expired + one hand weeding at 6 weeks after sowing (T2), pendimethalin expired (T3), pendimethalin expired + one hand weeding at 6 WAS (T4), two hand weeding at 3 and 6 WAS (T5), weed free check (T6) and weedy check (T7). Desmodium trifolium, Amaranthus spinosusand Commelina benghalensis were the most preponderant weedspecies. Both expired or non-expired pendimethalin and their integration with one hand weeding reduced weed population than other treatments. Pendimethalin non-expired + one hand weeding at 6WAS and two hand weeding at 3 and 6 WAS significantly increased the growth parameters and yield when compared with other treatments. In this study, two hand weeding at 3 and 6 WAS and non-expired pendimethalin + one hand weeding 6 WAS, should be reinforced for weed control on account of their positive influence on groundnut productivity and seed quality.

“…The highest value of WCE (97.26 %) was obtained from weed free check treatment. Pabitra Adhikary et al(2016) earlier also reported treatment receiving hand weeding twice recorded lowest weed biomass and highest W CE (85.09 %) which was significantly higher over other treatments. Amongst herbicides, the maximum value of WCE was achieved by of Imazethapyr + Imazomox 0.10 kg /ha (80.68%) followed by Propaquizofop 0.10 kg (77.39%).…”

Background: Groundnut encounters severe infestation of weed especially during the early stages of growth due to less crop canopy which allows higher weeds growth and thus crop becomes more susceptible to weed competition. During rainy season, effective and economical weed control is not possible through manual and mechanical weeding due to unfavorable soil conditions and also the unavailability of costly labours. Herbicides have been accepted as cost effective tool to manage weed menace in groundnut. The current study aims to study the efficancy of different post-emergence and pre-mix combination of post-emergence herbicides on weeds, growth and yield of groundnut. Methods: The field experiment was conducted at AICRP Weed Management field, Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (M.S.) during three consecutive Kharif seasons of 2015- 2017. The experiment was laid out in Randomized Block Design with ten treatments replicated thrice. The treatments comprised of one pre emergence and five different post emergence herbicides and compared with weed free and weedy check. Result: The results revealed that weed free was found most effective to control weeds in groundnut with lowest weed count, weed dry matter of weeds and maximum gross monetary returns (Rs.117641/ha), net monetary returns (Rs.80894/ha). Among the herbicides, application of Imazethapyr + Imazomox 0.10 kg /ha POE 20 DAS produced less weed count and weed dry matter and highest weed control efficiency (80.68%) and lower weed index (6.71% ) as well as maximum growth, yield attributes and pod yield in groundnut over all the other herbicidal treatments viz. plant height (30.25), dry matter accumulation (18.11g), number of pods/plant (32.35) and pod yield (2448 kg/ha) and highest pooled B:C ratio (3.74).
