Vitamin C content of guava from conventional versus organic farming system

The quality profile of organic and conventional guava grown in new alluvial zones of West Bengal were compared with emphasis on vitamin C content of fruit. In total 400 fruits (both growing system) were analyzed for a range of quality parameters. Data were analysed by ANOVA and means were compared by using t-test. Compared with conventional system, organic fruits were found rich in minerals like phosphorus, potassium, zinc, manganese and calcium. Maximum fruit weight (142.33 g) and yield (41.27 kg tree⁻¹) were obtained from conventional growing system, while quality parameter were higher in organically grown fruits. Vitamin C content of fruit was higher (139.27 mg 100 g⁻¹) in organic fruit as compared to conventional one. Finally, it is suggested that organic system can be recommended for the purpose of obtaining maximum vitamin C and other quality parameter.
