Effect of foliar nutrition on yield, quality and shelf-life of mango (Mangifera indica) cv. Dashehari under Jammu sub-tropics

The present investigation on effect of foliar nutrition on yield, quality and shelf-life of mango (Mangifera indica L.) was carried out on 20 years old mango trees cv. Dashehari having uniform vigour. The maximum fruit length (10.45cm), breadth (6.17cm), weight (170.17g) and highest fruit yield (99.72 kg/tree) of mango cv. Dashehari was recorded with the application of 2.0% Ca (NO3)2+ 2.0% KNO3 + 1.0% ZnSO4+0.02% H3BO3 (T14). The maximum leaf N (1.25%), P (0.16 %) and K (0.29 %) and soil N (230.79 kg/ha), P (14.75 kg/ha), K (139.09 kg/ha), Ca (6.25 kg/ha), Mg (2.76 meq/100g), Zn (0.97 ppm) and B (0.28 ppm) were recorded with the foliar application of 2.0% Ca(NO3)2 + 2.0% KNO3 + 1.0% ZnSO4 + 0.02% H3BO3 (T14). The findings indicated that the yield and nutrient status of mango cv. Dashehari can be improved with foliar application of 2.0% Ca (NO3)2 + 2.0% KNO3 + 1.0% ZnSO4 + 0.02% H3BO3 at pea stage.
