Abstract:
A present study was conducted with the objective to study the physico-chemical characters of fruit and soil nutrient status under different treatments of shoot retention and nutrition in the rejuvenated guava which was conducted during 2018-2019 at orchard of Fruit Science Department, Kittur Rani Channamma College of Horticulture, Arabhavi (UHS, Bagalkot), Karnataka. Among shoot thinning 3 shoots per branch (S₁) had highest fruit quality parameters viz., TSS (11.50 º B), Ascorbic acid (170.86 mg/100g), reducing (4.24%), non-reducing (3.48%), total sugars (7.72%), soil characters like pH (8.02), EC (0.28 dSm­^-1) and organic carbon (0.67%). Plants supplemented with 100% RDF (200: 80: 150 NPK g/plant) + (Zn+B+Mg) 0.3% each (F₆) has recorded maximum TSS (11.42 º B), Ascorbic acid (189.92 mg/100g), reducing (4.40%), non-reducing (3.46%), total sugars (7.86%) and soil characters like pH (8.01), EC (0.26 dSm­^-1) and organic carbon (0.66%). Interaction effect has got non-significant results for all the parameters. +However, the treatment S₁F₆ consisting of 3 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 fruit physico-chemical parameters and soil nutrient status.
