A study on the influence of nutrients and shoot retention on growth and yield in rejuvenated guava was conducted during 2018-2019 in the Department of Fruit Science, Kittur Rani Channamma College of Horticulture, Arabhavi (UHS, Bagalkot), Karnataka. Among shoot thinning, number of days for initiation of flowering (71.36), 50% flowering (81.17), completion of flowering (87.61) was least in 3 shoots per branch (S1), number of flowers per shoot and flowers per plant (25.18 and 75.85) were more in 4 shoots per branch (S2). Days for initiation of fruiting (86.33), 50% fruiting (97.96) and completion of fruiting (120.22) was least in S1. Number of fruits per plant (69.28) and yield (10.25 kg/plant) was highest in S2. Nutrient had significant effect on flowering and fruiting parameters in rejuvenated guava. Plants supplemented with 100% RDF (200: 80: 150 NPK g/plant) + (Zn+B+Mg) 0.3% each (F₆) has early initiation of flowering (71.72), 50% flowering (81.56), completion of flowering (87.56), higher number of flowers per shoot and flowers per plant (24.67 and 75.93), least days for initiation of fruiting (87.56), 50% fruiting (98.00) completion of fruiting (118.78), maximum number of fruits per plant (69.14) and yield (10.90 kg/plant). Interaction effect has got non-significant results for all the parameters. However, the treatment S₁F₆ flowers and fruit early but S₂F₆ has higher number of flowers per shoot and plant, maximum fruits per plant and yield.
