The research entitled “Effect of different bio-extracts on shelf life and physical parameters of papaya (Carica papaya L.) cv. Red Lady” was conducted at College of Horticulture, Rajendranagar, Hyderabad during the year 2019-2020. In the experiment, the design followed was Completely Randomized Design with three replications. The papaya fruits cv. Red Lady were coated with different bio-extracts i.e., T1: Aloe vera gel extract- 20%, T2 : Neem leaf extract- 20%, T3: Garlic extract- 10%, T4 : Ginger extract- 20%, T5 : Guar gum -1.5%, T6 : Acacia gum- 10%, T7 was taken as control and stored at ambient temperature. Fruits treated with neem leaf extract 20% (T2) recorded significantly lowest PLW (11.14%), ripening (93.33%), spoilage (42.22%) and significantly highest fruit firmness with peel (1.23 kg/ cm2) and fruit firmness without peel (0.93 kg/ cm2) at the end of storage. The highest shelf life (14 days) was observed in fruits treated with neem leaf extract 20% (T2) followed by garlic extract 10% (T3) (12.67 days). Hence, the research findings concluded that neem leaf extract 20% (T2) found to be best in increasing the shelf life and improving the physical parameters of papaya cv. Red Lady fruits at ambient temperature.
