The present investigation entitled "Effect of foliar application of different chemicals on quality of guava (Psidium guajava L.)" Var. Sardar was conducted in a well-established guava orchard on 9 years old Sardar guava trees planted at 6×6 m having uniform growth and productivity at the Instructional-Cum-Research Farm, Department of Horticulture, College of Agriculture, Latur, during mrig bahar 2013-14. The experiment was laid out in Randomized Block Design (RBD) with ten treatments replicated thrice. The treatments comprised of 19:19:19 @ 1% (T1), 12:61:0 @ 1% (T2), 0:52:34 @ 1% (T3), Calcium Nitrate @ 1% (T4), Sulphate of Potash @ 1% (T5), Calcium Nitrate @ 1% + Sulphate of Potash @ 1% (T6), ZnSO4 @ 0.5% + FeSO4 @ 0.5% + Boric acid @ 0.3% (T7), 19:19:19 @ 1% + ZnSO4 @ 0.5% + FeSO4 @ 0.5% + Boric acid @ 0.3% (T8), Calcium Nitrate @ 1% + Sulphate Potash + @ 1% + ZnSO4 @ 0.5% + FeSO4 @ 0.5% + Boric acid @ 0.3% (T9) and Control (T10). The results revealed that, the maximum values of diameter of fruit (9.17 cm), TSS (13.40 oBrix), TSS: acid ratio (34.36), acid: sugar (20.94) ratio were observed with the application of 0:52:34 @ 1% (T3) and at par results were observed in Sulphate of Potash @ 1% (T5) treatment. The minimum per cent weight loss (13.14%) at 8 days of storage and maximum shelf life of fruit (6.99 days) was observed in fruits obtained with the foliar application of calcium nitrate @ 1% + Sulphate of Potash @ 1% + ZnSO4 @ 0.5% + FeSO4 @ 0.5% + Boric acid @ 0.3% (T9). The minimum values for most of the quality attributes studied were observed in control (T10) treatment.
