The field experiment was conducted during rabi seasons of 2001–2002 and 2002–2003 at Instructional Farms, of Maharana Pratap University of Agriculture and Technology, Udaipur (Rajasthan), to study the effect of phosphorus and weed control practice on fenugreek. Taking 24 treatments combination of six phosphorus and four weed control practices i.e. control, PSB, 20 kg P2O5 ha−1, 20 kg P2O5 ha−1 + PSB, 40 kg P2O5 ha−1 and 40 kg P2O5 ha−1 + PSB for phosphorus and weedy check, hand weeding at 25 and 40 DAS, Pendimethalin 1.0 kg ha−1 (PE) and Pendimethalin 1.0 kg ha−1 (PE) + hand weeding at 25 DAS. It was laid out in randomized block design with three replications. The results of experiment revealed that application of 40 kg P2O5ha−1 + PSB significantly increased, the grains yield by 14.80 q ha−1 and 14.99 q ha−1, and the straw yield increased by and 41.95 q ha−1 and 42.35 q ha−1 during 2001–02 and 2002–03, respectively. The application of Pendimethalin @ 1.0 kg ha−1 + H. W. at 25 DAS reduced the weed population, drymatter and increased grain yield to the tune of 14.63 and 14.94 q ha−1 and straw yield by 40.02 and 41.04 q ha−1 respectively.
