A field study was conducted to know the effect of micronutrients on post harvest quality and shelf life of sapota cv. Kalipatti. Zinc and iron sulphates are used for soil and foliar application, boron for soil application sodium tetraborate (Jai bore) and for the foliar application solubor were used. The results indicated that the foliar application T10 -RDF + 0.5% ZnSO4 + 0.5% FeSO4 + 0.3% B per tree (i.e. in two times as foliar i.e. 1st at 50 per cent flowering and another at fruits at pea size) was gave physiological loss in weight of fruits 7.05% at three days after harvest and 1.35% at six after harvest over three days after harvest without effecting quality attributes, with promoted shelf life (12 days) with maximum per cent (23.25%) of total and minimum per cent (8.57%) of non-reducing sugars was promoted shelf life.
