        Manuring should be done immediately after pruning.  
        Training and pruning 
          The  main branches should be allowed to appear at a height of 0.75-1 m above the  ground level. Plants should be trained to modified central leader system. Two  to four branches with wide crotch angle, appearing in the opposite directions  should be encouraged in early years. 
          During March – April, prune  and thin the crowded branches to provide maximum fruit bearing area in the  tree.

        Plant protection 
          Pest  
          Gall caterpillar 
          Young caterpillars bore  into the apical portion of the shoot during rainy season and make tunnel. Due  to this, apical regrowth is checked, side shoots develop below the gall and  subsequent growth in following season is greatly hampered. Cutting off the  infected apices and prophylactic spray of systemic insecticide like Dimethoate 0.03  percent will control the pest. 
        Bark eating cater pillar  
          Damages the stem and  branches of grown up trees by eating the bark. The affected portion should be  cleared and few drops of kerosene should be applied in holes to keep this in  control.  
        Disease 
          Rust  
          Rust appears as circular  reddish solitary or gregarious on leaves and also on fruits. Spray 0.2 per cent  Mancozeb at an interval of 7 to 28 days during July to September. 
        Yield 
          The crop yields about 100 kg/tree  annually.
