Abstract: A field trial was conducted in Rabi season of 2016-17 and 2017-18 at MPUAT, Udaipur to study effect of irrigation and weed management practices on nodulation and yield of fenugreek. The experiment consisting of four levels of irrigation (0.4, 0.6, 0.8 and 1.0 IW/CPE ratios) in main plot and four weed control treatments (weedy check, pre emergence application of pendimethalin + imazethapyr (RM) 0.75 kg ha^-1 in conjugation with one hand weeding 40 DAS, imazethapyr 0.075 kg ha^-1 fb one hand weeding 40 DAS and two hand weeding 20 and 40 DAS) in sub plots was laid in split plot design with four replications. Irrigation at 0.8 IW/CPE ratio gave significantly more number of nodules per plant and their dry weight at 40, 60 and 75 DAS and leaf chlorophyll content in fresh leaf at 60 and75 DAS as well as seed, straw and biological yields over 0.6 and 0.4 IW/CPE ratio. Significantly more number of nodules per plant and their dry weight at 40 and 60 DAS and leaf chlorophyll content, higher seed yield, straw yield and biological yield were recorded with pre emergence application of pendimethalin + imazethapyr (RM) 0.75 kg ha^-1 in conjugation with one hand weeding 40 DAS followed by two hand weeding which were statistically at par with each other in this regard.
