    • Fertilizers are applied in 2 splits i.e. half of N and full of P and K during bahar treatment and remaining half of N 1-1½ month after first application.
    • Foliar application of urea (3 per cent) along with Calcium, Phosphate and Muriate of Potash (Kcl) at 1 per cent could increase the yield.
    • The deficiency of micronutrients such as Zn and B are rectified by spraying with Zns04 (0.3 per cent) and Boron – Boric acid (0.4 per cent) before flowering.
    Bronzing (Fatio disease):
    • The leaves turn to pale or purple color, small size leaves, sparse flowering, death of growing tips, ultimately plant dies.
    • It may be due to the deficiency of NPK, Zn, Mg and low pH, spraying of 0.5 per cent DAP and Znso4 during Oct-Nov at weekly intervals.
    Irrigation:
    • Immediately after planting, orchard is irrigated.
    • During summer and winter season orchard is irrigated at an interval of 4-6 and 10-15 days respectively
