Tomato (Solanum lycopersicum)
Solanaceae
Fertigation schedule for tomato hybrids
Recommended dose: 200:250: 250 kg / ha
Layout and Planting for drip irrigation & fertigation
- Apply FYM @ 25 t / ha as basal before last ploughing.
- Add 2 kg/ha of Azospirillum and 2 kg/ha Phosphobacteria with 50 kg of FYM.
- Apply 75 % total recommended dose of superphosphate ie 1172 kg / ha as basal.
- Install the drip irrigation with main and sub main pipes and place lateral tubes at an interval of 1.5 m.
- 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.
- Form raised beds of 120 cm width at an interval of 30 cm and place the laterals at the centre of each bed.
- Before planting, wet the beds using drip system for 8-12 hrs.
- Planting to be done at a spacing of 90 x 60 x 60 cm in the paired row system, using ropes marked at 60 cm spacing.
- Spray Pendimethalin 1.0 kg a.i. / ha or Fluchloralin 1.0 kg a.i / ha as pre-emergence herbicide at 3rd day after planting.
