Yield and quality parameters of guava fruits grown in conventional and organic farming system

The yield and quality profile of organic and conventionaly grown guava fruits in new alluvial zones of West Bengal were compared. In total, 400 fruits (from both growing systems) were analyzed for a range of quality parameters. Data were evaluated by ANOVA and means were compared by using t-test. Compared with conventional system, organic fruits were rich in minerals like phosphorus, potassium, zinc, manganese and calcium. More fruit weight and yield were obtained in conventionally grown system, while quality parameter and shelf life were better in organically grown fruits. An important constituent i.e. vitamin C content of guava fruits was also higher (139.27 mg 100g⁻¹) in organically grown fruits as compared to conventional once. Hence, organic system can be recommended for quality produce of guava.
