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 3 shoots per branch (S1) recorded maximum plant height (3.16 m), length of the shoot (132.48 cm), girth of the shoot (3.09 cm), number of leaves per shoot (76.94), Plant spread (N-S and E-S) (3.30 and 3.44 m), fruit physical parameters viz., Fruit length (6.48 cm), girth (6.58 cm), weight (162.82 g),number of fruits per plant (69.28), yield (2.85 t/ha). Nutrient had significant effect on growth and yield parameters in rejuvenated guava. Plants supplemented with 100 % RDF (200: 80: 150 NPK g/plant) + (Zn+B+Mg) 0.3 % each (F6) has recorded maximum plant height (3.11 m),length of the shoot (133.22 cm), girth of the shoot (3.00 cm), number of leaves per shoot (76.00), Plant spread (N-S and E-S) (3.25 and 3.32 m), fruit physical parameters viz., Fruit length (6.57 cm), girth (6.64 cm), weight(168.64 g), number of fruits per plant (69.14), yield (3.03 t/ha). Interaction effect has got non significant results for all the parameters. However, the treatment S2F6 consisting of 4 shoots per branch and 100 per cent RDF (200:80:150 NPK g/plant) + (Zn+B+Mg) 0.3 per cent each has recorded moderate vegetative and fruit physical parameters and highest leaves per plant (79.67), highest number of fruits per plant (73.96) and yield (3.30 t/ha) with highest benefit cost ratio of 2.02.
