The growing demand of papaya after the pandemic made the researchers think about its qualitative and quantitative production. In this regard, application of phyto-bio-regulators is a way forward approach to sustain the quality papaya production. The present investigation was conducted to determine the effect of various phyto bio stimulants on vegetative growth of papaya (Carica papaya) cv. Red Lady in a randomized block design using factorial arrangement during 2018-20. As many as 11 treatments and 3 replication includes five phyto bio stimulants with two different concentrations i.e. Naphthalene acetic acid (100 ppm and 150 ppm), Gibberellic acid (100 ppm and 150 ppm), Benzyl adenine (100 ppm and 150 ppm), Ethrel (100 ppm and 150 ppm) and 2,3,5-Triiodo benzoic acid (100 ppm and 150 ppm). The result revealed that gibberellic acid @150 ppm significantly increased the plant height, as compared to control in papaya cv. Red Lady. Among the various vegetative characters, the effect of phyto bio-regulator Gibberellic acid @150 ppm (T4) imparts the significant effect over control with respect to plant height and number of leaves at 60, 90, 120, 150, 180 days after transplanting and at maturity. However, the maximum plant girth, petiole length and plant spread was observed under treatment T10 (2,3,5-Triiodo benzoic acid @150 ppm) as compared to control.
