A two year study was undertaken to examine the effect of differential irrigation (Regulated deficit irrigation and partial root zone drying) on shelf life of mango grown in open field conditions. The experimental treatments included ten levels of irrigation. The study revealed that with the advancement of storage life, the per cent TSS, acidity, reducing, non-reducing sugar, total sugar and carotenoids increased significantly up to 6ᵗʰ day of storage and then decreased on 8ᵗʰ and 10ᵗʰ day of storage. On mean value basis maximum TSS (17.42%), reducing sugar (6.40%), non-reducing sugar (9.15%) and total sugar (16.03%) was in PRD 50% ETc + F whereas maximum carotenoids content (8.43 mg/100g of pulp) was with no irrigation treatment whereas the pectin content of fruit pulp decreased with corresponding increase in storage period. On mean value basis maximum pectin content was recorded in PRD 50% ETc + F (0.295 per cent)whereas, minimum pectin content (0.200 per cent) in the pooled data was r in no irrigation treatment throughout the storage period.
