The present investigation carried out to evaluate effects of doses of N, P and K on the growth, flowering, yield and fruit quality of Guava variety L-49 at Fruit Research Station, Lalbaug, CoH, JAU, Junagadh, during the years 2022-23 and 2023-24 in meadow orchard. The experiment was laid out in RBD with Factorial concept consisting three levels of nitrogen N₁:30, N₂:60 and N₃:90 g/plant, two levels of phosphorus P₁:15 and P₂:30 g/plant and three levels of potash K₁:15, K₂:30 and K₃:45 g/plant. The results revealed that the minimum days to first flowering, days from flowering to fruit set and days to first harvest were recorded with treatment N₂, P₂ and K₂, while highest number of flowers/shoot was recorded with N₃, P₂ and K₂. For yield and yield attributing parameters, the highest fruit set, number of fruits/shoot, fruit weight, yield/plant was recorded in treatment N₃, P₂ and K₂. For quality parameters, maximum TSS, ascorbic acid content and total sugar was recorded in N₂, P₂ and K₂. The interaction effect of nitrogen, phosphorus and potash showed that maximum fruit weight and yield (kg/plant) were observed in N₃K₂. While, maximum TSS and Total Sugar were found in in N₂K₂.
