dc.description.abstractThe field experiment was conducted to assess the effect of herbicides on weed growth and performance of Mung Bean (Vigna radiata) during the Kharif season of 2021 in the weed control (E) block of NEB,CRC at G.B Pant University of Agriculture and Technology, Pantnagar (UK) which falls under a sub-humid, sub-tropical climate with hot and dry summers and severe cool winters along with soil type of silty clay loam having high organic carbon (0.77%), medium available nitrogen (309.5kg/ha), available potassium (269.4kg/ha) and high available phosphorus (25.2kg/ha). The experiment comprised of 10 treatments viz.T1-pendimethalin 1kg/ha (PE), T2- pendimethalin 1kg/ha (PE) fb one hand weeding at 20 DAS, T3- fomesafen +fluazifop-p-butyl 250 g/ha (RM) (PoE) at 15 DAS, T4-fluazifop-p-butyl 150g/ha (PoE) at 15 DAS, T5-quizolfop ethyl 50g/ha (PoE) at 15 DAS, T6-propaquizafop 75g/ha (PoE) at 15 DAS, T7- sodium acifluorfen + clodinafop-propargyl 245g/ha (RM) (PoE) at 15 DAS, T8-pendimethalin 1kg/ha (PE) fb fluazifop-p-butyl 150g/ha (PoE) at 15 DAS, T9-hand weeding at 20 and 40 DAS and T10-unweeded control. The field experiment was laid in RBD with three replications using mung bean verity Pant mung-2 on 8 August 2021. Dominant weed species in the experimental field were Trianthema portulacastrum (27.9%), Cyperus rotundus (22.0%), Mollugo pentaphylla (24.5%), Cynodon dactylon (1.8%) and Digitaria sanguinalis (6.2%). Hand weeding at 20 and 40 DAS showed maximum weed control efficiency among all treatments followed by pendimethalin 1kg/ha (PE) fb one hand weeding at 20 DAS and fomesafen +fluazifop-p-butyl 250 g/ha (RM) (PoE) at 15 DAS were also showed higher weed control efficiency. Hand weeding at 20 and 40 DAS was having the maximum number of branches per plant (8.5), number of trifoliate leaves per plant (9.8) and dry matter accumulation per plant (20.8) followed by pendimethalin 1kg/ha (PE) fb one hand weeding at 20 DAS and fomesafen +fluazifop-p-butyl 250 g/ha (RM) (PoE) at 15 DAS showed higher values. Yield attributing characters like number of pods per plant (16.0), number of grain per pod (7.0), 1000- grain weight (35.3) and grain yield per plant (4.1) were also found maximum in hand weeding at 20 and 40 DAS and it was followed by pendimethalin 1kg/ha (PE) fb one hand weeding at 20 DAS and fomesafen +fluazifop-p-butyl 250 g/ha (RM) (PoE) at 15 DAS. Hand weeding at 20 and 40 DAS recorded higher nutrients uptake (N, P and K) per hectare than other treatments. Fomesafen +fluazifop-p-butyl 250 g/ha (RM) (PoE) at 15 DAS recorded highest B:C ratio (2.95) among all the treatments.en_US
