The present study was carried out under ambient storage condition which is located at P. G. Laboratory, Department of Horticulture, B. A. College of Agriculture, Anand Agricultural University, Anand, Gujarat, India during the year rabi 2017 to investigate the “Effect of grading and post-harvest application of chemicals on quality and shelf life of custard apple (Annona squamosa L.) cv. Balanagar”. The experiment was laid out in Completely Randomized Design with Factorial concept having ten treatment combinations. An experiment comprised with two factors (1) Grade – A, Grade – B and (2) two chemical levels of Ascorbic acid (500 and 1000 mg/l), and KMnO4 (0.05 and 0.1%) of custard apple fruit viz., Balanagar along with control. The treatments were repeated thrice. Among all the treatments, treatment G1 (Grade – A) was most effective treatment and which was recorded significantly minimum acidity, maximum ascorbic acid, total sugar, reducing sugar and non-reducing sugar whereas treatment C4 (KMnO4 @ 0.1%) recorded significantly maximum Total soluble solid, Total sugar, Reducing sugar and Non- reducing sugar and Application of ascorbic acid @ 1000 mg/l effective for increasing ascorbic acid while minimum acidity was recorded in control in custard apple fruits under ambient storage condition.
