Abstract: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.
