Seed :: Vegetables :: Tomato
Season
  • November – March ; June – July
Seed rate
  • 300 g/ha
Pre-sowing seed treatment
  • Seed fortification with 1000 ppm gelatin or 2 % KNO3 or 200 ppm salicylic acid (soaking in double the volume for 12 h) followed by coating with carbendazim (2 g / kg) + imidachloprid (6 g / kg) + polymer (20 g / kg of seed in 40 ml of water). (or)
  • Coating with white red polykote (6 g / kg of seed) + Pseudomonas fluorescens (10 g/ kg), Trichoderma viride  (4 g / kg) + DAP  (4 g / kg) + MN mixture (20 g / kg). (or)
  • Soak the seeds in 50 per cent coconut water for 12 h.


Nursery treatment
  • The nursery should be drenched with Metham sodium @ 28 ml/sq.m. (VEPAM) 15 days before sowing
  • For controlling the nematodes and with Copper oxychloride @ 2.5 g/lit after 7 days to prevent damping off
Age of seedling
  • 25 - 30 days
Spacing

CO 1               : 60 x 60 cm
PKM 1            : 75 x 60 cm
CO 2               : 80 x 75 cm
Pusa Ruby    : 80 x 70 cm
CO 3               : 60 x 30 cm


Fertilizers

  • Basal: FYM - 25 t/ha
  • NPK recomended dose ratio of 75: 100: 100 Kg/ha
  • Top dressing: At the time of flowering applying 75 Kg N

Foliar application
  • Foliar applicationis recomended for enhanced furit emergence
  • Napthalin Acitic Acid (NAA) @ 20 pm at 65 and 75 days after transplanting



Harvest
  • Seeds attain physiological maturity 30 – 35 days after flowering. Fully matured, red, ripened and healthy fruits  alone should be harvested.
  • First 7 - 8 pickings should be used for seed extraction
Seed extraction
  • Well-matured fruits are crushed and made into pulp. For every 1 kg of pulp 25 - 30 ml of commercial HCl acid should be added  and left for 30 min
  • with constant stirring. At the end of 30 min. the seeds are washed for 3 - 4 times with water and shade dried for one day followed by mild sun drying to reduce the mositure content to 7-8%

 


Harvesting Seed extraction

Grading
  • Seeds are graded with BSS : 12 x 12 wire mesh (2.1 mm) sieve.
Seed yield
  • 150 kg/ha.
Storage
  • Seeds dried  to 7 - 8 % moisture are treated with carbendazim 50 % WP @ 2 g / kg seed or halogen formulation (Bleaching powder + CaCO3 + Arappu leafpowder @ 5:4:1) @ 3 g/kg seed or with white polykote @ 6 g + carbendazim 2 g + Dimethoate 5 ml / kg of seed using 5 ml water. The treated seeds can be stored upto 12 months in aluminium foil pouches
