The present study was conducted to evaluate the effect of foliar application of bio-enhancers namely panchagavya, jeevamrut, beejamrut and cow urine on vegetative parameters of brinjal. The experiment was carried out at the Horticulture Research Farm, Chaudhary Charan Singh University, Meerut, Uttar Pradesh during the years 2021-22 and 2022-23. The experiment was laid out in Randomized Block Design with three replications. A total of seventeen treatments were included, comprising different concentrations of Panchagavya (2%, 4%, 6% and 8%), Beejamrut (2%, 4%, 6% and 8%), Jeevamrut (2%, 4%, 6% and 8%) and cow urine (10%, 20%, 30% and 40%), along with a control treatment (distilled water). The bio-enhancers were applied as foliar spray at three different growth stages i.e. 30, 40 & 75 days after transplanting. Among all the treatments, maximum plant height (86.65 cm), number of branches per plant (6.11), number of leaves per plant (95.92), leaf length (14.17 cm), leaf width (6.79 cm) fresh weight of plant (1089.05g) and dry weight of plant (185.13g) were rescored under foliar application of Panchagavya @ 4%. However maximum stem diameter (1.88 cm), and root length (57.92 cm) were noted with the foliar spray of Jeevamrut 8%. Beejamrut and cow urine foliar spray were also found significant to enhance vegetative growth of brinjal as compared to control treatment in the study. In contrast, the control treatment (distilled water) showed the minimum vegetative growth.
