        Seed treatment 
        Treated  with Trichoderma viride 4 g or Pseudomonas fluorescens 10 g or  Carbendazim 2 g/kg of seeds before sowing 
        Preparation of field 
        Plough  the field to fine tilth and dig pits of the 30 cm x 30 cm x 30 cm size at 2.5 x  2 m spacing. 
        Sowing 
          Sow the seeds @ three  seeds/pit and thin the seedlings to two/pit after 15 days.  
        Irrigation 
        Irrigate  the field before dibbling the seeds and thereafter once a week. 
        Application of  fertilizers 
        Apply  10 kg of FYM (20 t/ha), 100 g of NPK 6:12:12 mixture/pit as basal and 10 g of N/pit  30 days after sowing.Apply  Azospirillum and Phosphobacteria 2 kg/ha and Pseudomonas 2.5 kg/ha along with  FYM 50 kg and neem cake @ 100 kg before last ploughing. 
        Drip irrigation  
          Install  drip system with main and sub-main pipes and place the inline lateral tubes at  an interval of 1.5m. Place the drippers at an interval of 60 cm and 50 cm  spacing with 4LPH and 3.5LPH capacities respectively. 
        Field preparation  
          Form raised  beds of 120 cm width and place laterals in the centre of bed. 
        Nursery  raising  
          In hi-tech horticulture, plant 15 days old  healthy seedlings raised in shade net houses. Raise the seedlings in protrays  having 98 cells or in polythene bags. Transplant about 15 days old seedlings in  the main field.  
        Fertigation  
          Apply a dose of 200:100:100 kg NPK/ha  throughout the cropping period through split application.
