Abstract

The present investigation was to find effective pre harvest spray combination to maintain post-harvest quality and shelf life of grapes cv. Manjri Naveen. The pre harvest sprays viz., T1: NAA 100 ppm; T2: Salicylic acid 4 mM; T3: Ca(NO3)2 (1%) T4: B. amyloliquefaciens (10 ml/L); T5: NAA 100 ppm + Ca(NO3)2 (1%); T6: NAA 100 ppm + B. amyloliquefaciens (10 ml/L); T7: Salicylic acid 4 mM + Ca(NO3)2 (1%); T8: Salicylic acid 4 mM + B. amyloliquefaciens (10 ml/L); T9: Ca(NO3)2 (1%) + B amyloliquefaciens (10 ml/L); T10: NAA 100 ppm + Ca(NO3)2 (1%) + B. amyloliquefaciens (10 ml/L); T11: Salicylic acid 4 mM + Ca(NO3)2 (1%) + B. amyloliquefaciens (10 ml/L); T12: Control; were sprayed on the stipulated day, harvested, packed in CFB boxes, and stored under refrigerated condition (5±1˚C and 85-90% RH). Grape bunches sprayed with T10 recorded minimum PLW (2.76%), berry drop (1.96%), maximum firmness (26.97 N), and overall acceptability score (8.46) bunches sprayed with salicylic acid 4 mM + Ca(NO3)2 (1%) + B. amyloliquefaciens (10 ml/L) recorded maximum rachis freshness (8.16) and minimum disease score (0.50). These treatments were found effective in maintaining 5 days more shelf life compared to the control.
