The present investigation entitled “Effect of cow urine and Plant Growth Promoting Rhizobacteria (PGPR) on seed germination, growth and survival of Karonda (Carissa carandas L.) seedlings” was conducted at Fruit Research Station, Imalia, Department of Horticulture, College of Agriculture, J.N.K.V.V., Jabalpur (M.P.) during the year 2018 - 2019. The experiment was laid out in Factorial Randomized Block Design with three replications. The experiment consist of 8 treatments T0 (Control), T1 (25% cow urine), T2 (50% cow urine), T3 (100% cow urine), T4 (Pseudomonas 6ml/kg seeds), T5 (25% cow urine + Pseudomonas 6ml/kg seeds), T6 (50% cow urine + Pseudomonas 6ml/kg seeds), T7 (100% cow urine + Pseudomonas 6ml/kg seeds). All the seed and soil inoculation treatments showed better germination, growth and survival when compared to uninoculated control. Among various combinations, the combined effect of seed treatment with 25% cow urine and soil inoculation with 6ml/ kg pseudomonas were more superior over the other combinations with highest seed germination (5.33 days), 50% germination (14.50 days), germination at 60 DAS (79.63%), coefficient of germination (6.10), speed of germination (9.15). Growth parameters at 60, 90 and 120 DAS with seedling height (8.75, 11.20 and 12.60 cm), stem girth (1.98, 2.36 and 2.64 mm), number of leaves per seedling (29.3, 72.2 and 89.4) respectively, other growth parameters at 120 DAS such as length of seedling (28.39 cm), number of roots per seedling (118.3), fresh weight of seedlings (3.41g), dry weight of seedlings (1.43g), seedling vigor index I (2269.7 cm), seedling vigor index II (106.8g), survival of seedlings (81.4%), leaf area index (4.09), leaf area duration (677798 cm2.days), light transmission ratio (34.52%) and energy interception (0.44 cal cm-2 min-1).
