        Cucurbitaceae  
        Varieties  
       Japanese Long Green, Straight Eight and  Poinsettee. 
       Hybrids:  
       KPCH 2, Pant C 2.  
        Soil  
        Sandy loam rich in organic matter with good drainage and pH range of 6.5-7.5.. 
        Season 
          Sow the seeds during June or January to April  
        Seed  rate 
          About 2.5 kg of seeds are  required for a hectare. 
        Seed treatment 
          Treat the seeds with Trichoderma viride 4 g/kg or Pseudomonas  fluorescens 10 g/kg or Carbendazim 2 g/kg of seeds before sowing. 
        Preparation  of field  
          Plough the field four times and form long channels  at 1.5 m apart. 
        Sowing  
          Sow the seeds on one side of channel giving a  spacing of 0.6 m between hills. Thin the seedlings to two/hill at 15 days after  planting. 
        Irrigation  
        Irrigate the field before dibbling the seeds and  thereafter once a week. 
        Application  of fertilizers  
          Apply FYM 40 t/ha as basal and 35 kg of N/ha at 30  days after sowing.Apply  Azospirillum and Phosphobacteria 2 kg/ha and Pseudomonoas 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 in lateral tubes at an interval of 60  cm and 50 cm spacing with 4 LPH and 3.5 LPH capacities respectively.  
        Field preparation 
          Form raised  beds of 120 cm width at an interval of 30 cm and the laterals are placed at the  centre of each bed.  
        Sowing 
          Sow the  seeds at an interval of 60 cm distance at the centre of the bed along the  laterals. Sow the seeds in polybags @ one per bag for gap filling. Spray pre  emergence weedicide like fluchloralin 1 kg a.i. or metalachlor 0.75 kg a.i./ha on  third day of sowing.  
        Fertigation 
          Apply a dose  of 150:75:75 kg NPK/ha throughout the cropping period through split application  for F1 hybrid. In respect of phosphorous, 75% has to be applied as a basal  dose.

Plant protection 
          Pest  
          Fruit fly  
          1. Collect  the affected fruits and destroy. 
          2. The  fly population is low in hot day conditions and it is peak in rainy  season.  Hence adjust the sowing time  accordingly. 
          3. Expose  the pupae by ploughing. 
          4. Use  polythene bags, fish meal trap with 5 g of wet fish meal and 1 g of Dichlorvos in  cotton, 50 traps are required per hectare. Fish meal and Dichlorvos impregnated cotton are to be renewed once in 20  and 7 days respectively. 
          5.Neem oil  @  3.0 %  as foliar spray as need based  
          6.Install cucurbit fruit fly trap @ 4/ acre.  
           
        Do  not use copper and sulphur dust, as these are phytotoxic. 
        Disease 
          Downy mildew 
          Downy  mildew can be controlled by spraying Mancozeb or Chlorothalonil 2 g/lit twice  at 10 days interval. 
        Do not use DDT,  copper and sulphur dust, as these are phytotoxic.  
        Harvest 
          Harvest can be done 45 days after sowing. On an  average 8 – 10 harvests can be done. 
          Aphids &Jassids : 
         Spray Imidacloprid 70 WG 1.0g/10lit.  
         Yield 
        8 - 10 t/ha in 80 to 90 days for salad.
