Abstract: The field experiment entitled “Effect of seed priming and urea foliar application on the performance of the soybean (Glycine max L.)” was conducted at Research Farm of University College of Agriculture, Guru Kashi University, Talwandi Sabo, Bathinda during kharif season 2019. The trail was laid out in split plot design with two levels of foliar application of urea (control, 2%) at 60 and 75 DAS, in main plots and four seed priming levels (0,3,6 and 9hours, duration) in sub plots, replicated thrice. 2% foliar application of urea recorded significantly higher emergence count plants m^-1 row length (12.84), plant height cm (127.8), dry matter accumulation g plant^-1 (78.61), number of leaves plant^-1 (90.85), number of branches plant^-1 (9.44), number of pods plant^-1 (87.68), number of seeds pod^-1 (2.85), test weight g(100), grain yield q ha^-1 (30.96), straw yield q ha^-1 (56.08) and biological yield q ha^-1 (87.05) than other control treatment, Seed priming at 9 hr q ha^-1 (31.07) resulted in higher grain yield than 0, 3 and 6 hr respectively. The emergence count plants m^-1 row length (12.67), plant height cm (126.5), dry matter accumulation g plant^-1 (78.07), number of leaves plant^-1 (89.90), number of branches plant^-1 (9.53), number of seeds pod^-1 (2.95), test weight g(100), grain yield q ha^-1 (31.07), straw yield q ha^-1 (54.56) and biological yield q ha^-1 (85.63) was recorded significantly higher 9 hour priming treatment but it was at par with the application of seed priming 6 hr. The application of 9hr seed priming found maximum grain yield q ha^-1 (31.07) resulted in 7.4, 4.2 and 2.7% higher grain yield than 0, 3 and 6hr seed priming respectively.
