Effect of Wrapping Materials Combination of Growth Regulators on Physical Characters and Storage Life of Papaya (Carica papaya L.) cv Red Lady

Abstract

The experiment was conducted to assess the effect of different wrapping materials and growth regulators on physical characters, storage life and quality of papaya cv Red lady was stored at room temperature during the investigated. The fruits are harvested best treatment of INM (i.e 75% RDF+10 kg vermicompost + 100 g Azotobacter + 100 g PSB plant-1) fruits harvested dipped in different growth regulators and combined with packaging materials imposed in the present investigation showed lowest loss in weight (PLW) in fruits treated with CaCl2 @ 3.0% and packed with news paper (7.65%), whereas, highest PLW was found in control (38.93%). Maximum fruit firmness was observed in the fruits treated with T1- CaCl2 @ 3.0% and wrapping with news paper (2.03 kg cm-2) and T1 recorded significantly minimum spoilage (23.34%) over other treatments. Maximum TSS recorded in T7 control (10.80 OBrix). The storage life was found maximum in T1 - fruits dipped in CaCl2 @ 3.0% and wrapping with news paper (17.58 days) and followed by T3- GA3 @ 100 ppm and wrapping with news paper (16.25 days). However, control has shown poor storage life (9.00 days).
