Abstract:
Field experiment was conducted at Fruit Research Station, Sakkarbaug Farm, Junagadh Agricultural University, Junagadh during the year 2022. As a result, number of fruits per plant (93.93), fruit yield per plant (16.22 kg), yield per hectare (12.01 tonnes) and reducing sugar (3.94%) were found in 100% RDN (U₁). Regarding nano-urea, maximum fruit set (75.33%), number of fruits per plant (102.58), fruit yield per plant (18.64 kg), fruit yield per hectare (13.81 tonnes) and minimum titratable acidity (0.35%) were registered in 0.1% nano-urea (N₁). Maximum non-reducing sugar (2.43%) and TSS (14.58 ˚Brix) were noted in 0.2% (N₂) and 0.4% nano-urea (N₃), respectively. For interaction effect, maximum number of fruits per plant (112.00), fruit yield per plant (18.66 kg) and yield per hectare (13.82 tonnes) were reported in 100% RDN + 0.1% nano-urea (U₁N₁). Likewise, maximum total sugar (6.73%), reducing sugar (4.09%) and non-reducing sugar (2.64%) were observed in 100% RDN + 0.2% N through nano-urea (U₁N₂). Accordingly, this investigation revealed that an application of 100% RDN with 0.1% nano-urea increased fruit yield and quality of guava.
