Abstract: A study was conducted to determine the impact of different plant age and maturity stages on physical characteristics of Sweet orange cv. Malta. The fruits were harvested from three different age groups i.e. 5 years, 8 years and 13 years respectively at premature stage (22th August) and at mature stage (22th october). The study was carried out at Agriculture Lab, D.A.V College, Abohar during the year 2017-18. Various physical parameters such as fruit size (length and breadth), fruit weight, fruit volume and specific gravity were evaluated. Total of 12 samples were taken from all age groups and at different maturity stages (4 samples from each age group at two stages). It was concluded that Sweet orange cv. Malta fruit samples showed significant increase in its physical characters in all age groups during maturity except specific gravity which were decrease during maturity. The fruit samples from 13 year old plants with maturity showed best quality characteristics and November month is suited as best for harvesting of Sweet orange cv. Malta.
