Abstract: The present study was undertaken to investigate “Effect of pre- harvest application of plant growth regulators and calcium salts on fruit quality and shelf life of acid lime (Citrus aurantifolia Swingle)’’ was conducted in the Instructional cum Research Fruit Orchard, Department of Fruit Science, College of Horticulture, Mandsaur, Rajmata Vijayaraje Scindia Krishi Vishwa Vidyalaya, Gwalior (M.P.) during 2017-2018. In this experiments the treatments consisting of plant growth regulators and calcium salts i.e. Gibberellic acid (20 ppm, 40 ppm and 60 ppm), Napthalene acetic acid (10 ppm, 15 ppm, 20 ppm), Calcium Nitrate (0.5%, 1% and 1.5%) and Calcium Chloride (1%, 1.5% and 2%). The significant results showed minimum mean Total Soluble Solids (6.82 0brix), rag percentage (45.46%), TSS: acid ratio (0.98), mean decay loss (10.48%) and maximum mean acidity (6.95%), ascorbic acid (30.49 mg/100g), percentage of marketable fruits (89.52 was recorded in treatment (T₉) (Calcium Nitrate 1.5%). compared to control after harvest during the storage period upto the 15 days.
