“…The regression studies also suggest that each unit increase in these parameters was responsible for 72, 869, 922 and 338 kg ha -1 increased in theseed yield. These results are in close conformity with the findings of Mehta et al (2010), Singh et al (2013), Verma et al, 2017, Singh et al (2014 and Kumar et al (2016). The yield was increased significantly by alone application of imazethapyr (PoE) and imazethapyr + imazamox (PoE) over weedy check.…”

“…Lowest B:C ratio 0.87 was recorded (Table 2) in weedy check on pooled basis. Similar findings were also reported by Meena et al (2013), Singh et al (2013), Singh et al (2014) and Kumar et al (2016). The maximum net return and BCR was recorded with two hand weeding at 20 and 40 DAS which were at par with each other and significantly higher over rest of the weed management treatments.…”

“…The correlation studies also showed a well-established significant negative correlation between seed yield and weed dry matter at harvest with the respective value of r = -0.789. The superiority of herbicide in integration with hoeing or weeding at 40 DAS was also been reported by Singh et al (2013), Singh et al (2014), Kumar et al (2016), Punia and Tehlan (2017).…”

“…Weed management practices reduced the weed infestation and create condition more favorable for crop growth. Tiwari et al, (2006), Mehta et al, (2010), Bagotiya et al, (2018), Singh et al (2013) Singh et al (2014 and Kumar et al, 2016 also reported that treatment combination of Vermicompost 2 t/ha with hand weeding carried out at 20 and 40 DAS was found effective in reducing density as well as weed dry biomass of weeds. It is obvious from the pooled estimates of investigation that application of vermicompost resulted in significantly higher pods plant -1 and seed weight plant -1 .…”

Background: A field experiment was conducted at the Instructional Farm of Rajasthan College of Agriculture, Maharana Pratap University of Agriculture and Technology, Udaipur during Rabi 2016-17 and 2017-18 to study the weed flora, growth, yield and economics of fenugreek. The experiment was laid out in split plot design with three replications having Fenugreek variety RMT-305 (25 kg ha-1) and RDF of 40 kg N and 40 kg P2O5 ha-1 (basal dose through urea and DAP). Methods: Herbicide applied as pre-emergence (PE) at one day after sowing, while post-emergence (PoE) application at 2-4 leaf stage of weeds (21 DAS) with knapsack sprayer having flat fan nozzle using 500 liters of water ha-1. Result: The pooled results revealed that pre-emergence application of oxadiargyl 100 g/ha fb hoeing at 40 DAS recorded significantly higher weed control efficiency (82.3%), plant height (59.83 cm), number of branches (6.09), number of pods (44.86), number of seeds/pod (17.33), seed weight (9.05 g/plant) of fenugreek. Also, significantly maximum seed yield (2.82 t/ha), haulm yield (6.70 t/ha) and harvest index (29.7%) of fenugreek was recorded under oxadiargyl 100 g/ha PE fb hoeing at 40 DAS which was at par with weed free treatment. Significantly higher net returns (98158 `/ha) and B C ratio (2.63) was obtained with application of oxadiargyl 100 g/ha Pre-Emergence (PE) fb hoeing at 40 DAS. Residual effect of herbicides used in fenugreek did not showed any phytotoxic effect on succeeding summer fodder maize in terms of visual phytotoxicity rating at various growth stages of maize, weed flora, dry matter of weeds as well as crop at 30 DAS and green fodder yield of summer fodder maize.

A field experiment conducted at Instructional farm, Rajasthan College of Agriculture, MPUAT, Udaipur during rabi 2016-17 and 2017-18 to study the effect of weed management practices on weed control and seed yield of fenugreek. The experiment consists of thirteen weed management treatments comprising imazethapyr (70 g ha -1 , 70 g ha -1 fb hoeing at 40 DAS), imazethapye 50 g ha -1 at 2-4 leaf stage of weeds, imazethapyr + imazamox 50 and 60 g ha -1 at 2-4 leaf stage of weeds, pendimethalin 750 g ha -1 PE, oxyfluorfen (120, 150 g ha -1 and 120 g ha -1 fb hoeing at harvest, oxadiargyl (100 g ha -1 and 100 g ha -1 fb hoeing at 40 DAS) including weed free and weedy check in main plot treatments and levels of vermicompost, viz. control and 5 t ha -1 in sub plot treatments. The experiment was laid out in split plot design with three replications. The soil of experimental field was clay loam in texture, slightly alkaline in reaction, medium in organic carbon, available nitrogen, available phosphorus and high in available potassium. Fenugreek variety RMT-305 was sown at 30 cm distance with 25 kg ha -1 seed rate and fertilize with recommended dose of fertilizers. Pre-emergence application of oxadiargyl 100 g ha -1 followed by hoeing at 40 DAS recorded significantly lower weed density (15.00 m -2 ) and weed dry matter (54.20 g m -2 ), higher weed control efficiency (86.29% ), crop resistance index (10.20), weed persistence index (1.79%) and lowest weed index (3.03% ). Also the same treatment recorded higher growth, yield attributes and seed yield (2820 kg ha -1 ) of fenugreek however this treatment was remained at par with weed free check.
