The present investigation entitled “Effect of growth regulators and chemicals on germination and growth of rangpur lime seedlings under nursery condition”was carried out at the Instructional Cum Research Farm, sweet orange research station Badnapur, Dist- Jalna during the year 2016- 2017. The experiment was laid out in Randomized Block Design with thirteen treatments replicated thrice. The seeds will be soaked in different concentrations of GA3 (50, 100 and 150 ppm), KNO3 (0.5%, 1%, 2%), NAA (50,100 and 150 ppm) Thiourea (1%, 1.5% and 2%) water soaking as control for 24 hours in beaker. The results of the investigation revealed that,the seeds soaked in GA3 150 ppm solution for 12 hours prior to sowing resulted in maximum germination percentage (91.33 %). The maximum height (52.12 cm), maximum number of leaves (46.59), maximum fresh weight (31.35 g) and dry weight of shoots (16.40 g) was also recorded under the treatment T3 i.e. GA3 150 ppm at 270 DAS. The maximum number of branches (6.66) was recorded under the treatment T12 i.e. Thiourea 2% at 270 DAS and the maximum circumference of stem (22.23 mm), was recorded under the treatment T6 i.e. NAA 150 ppm at 270 DAS.
