ABSTRACT
The Field investigations were carried out know the effect of organic, inorganic and bio-fertilizers on growth and yield of guava (Psidium guajava L.) cv. Lalit" was carried out at Regional Horticulture Research Station, College of Horticulture, Bengaluru. The vegetative growth and yield was significantly influenced at different spacing levels (2 x 2, 3 x 3, 6 x 3 and 6 x 6 m). In rainy season the maximum plant height (2.81 m), plant spread (N-S direction) (2.85 m), plant spread (E-W direction) (2.69 m) and canopy volume (11.76 m3), number of fruits (171.74), fruit yield per tree (12.63 kg), TSS (15.14°B), minimum titratable acidity (0.44 %), ascorbic acid (169.24 mg 100-1 g pulp) was observed in 6 x 6 m spacing. Whereas, the fruit yield (16.74 t ha-1) was maximum in 2 x 2 m spacing, the minimum physiological loss of weight (8.51 %), mean shelf life of life (6.83 days) were observed in 2 x 2 m spacing whereas, the integrated nutrient management significantly influenced vegetative growth characteristics after 8 month of growth stage the maximum plant height (2.81 m), plant spread (N-S & E-W) 2.74 & 2.67 m respectively, and canopy volume (11.71 m3), number of fruits (236.06), fruit yield per tree (15.71 kg), fruit yield (15.08 t ha-1), TSS (15.77°B), titratable acidity (0.34 %), ascorbic acid (184.52 mg 100-1 g pulp), physiological loss of weight (6.85 %), mean shelf life of life (7.17 days) was observed in (T10) Azotobacter @ 20 g + PSB @ 20 g + vermicompost @ 10 kg + 50 % recommended NPK.
Key words: organic, inorganic and bio-fertilizers, guava, vegetative growth, yield, quality attributes.
