Production technology: from seed to product.
Possible tracks from seed to market
2
Wet season ------ Dry season
Two step cultivation:
Preparing starting material
Producing consumption
Content
▪ Producing minibulbs
● Indramayu (clay) and Lembang (Andosol)
▪ TSS systems
● Purwakarta (clay) and Sumbawa (loam)
▪ Effect of transplant quality
● Garut (clay)
4
Soil type based on personal observations
Tests in 2019
▪ Purwakarta and Sumbawa
▪ Production methods:
● Direct sowing
● Transplants
● Minibulbs (Production at Indramayu and Lembang)
▪ Periods:
● Early (Start wet to dry season)
● Mid (dry season)
● Late (dry season end at begin of wet season)

Direct sowing
Nursery Field
Producing minibulbs in wet
season
Sanren: TKW = 3.8 g
Direct sowing
● 700 sd/m2
● 1000 sd/m2
Transplant (nursery phase)
● 5 g/m2 (1315 sd/m2)
● 10 g/m2 (2630 sd/m2)
● Transplanting at 5 x 10 cm

Quality.....
▪ Wet season
▪ Fusarium and other soil borne issues
▪ Poor storability

Lembang: minibulb production
▪ Varieties
● Trisula
● Sanren
● Maserati
▪ Sowing densities:
● 750 sd/m2
● 1000 sd/m2

Conclusions:
▪ Minibulb production difficult to obtain high quality for storing in wet season.
▪ TSS direct sowing not suitable for early start
▪ TSS transplant “ stable results” for all seasons.
▪ For transplant take care of transplant quality
● Logistics
● Age
● Source (raising method/fertilization/season)
21
Final considerations
▪ TSS starting material
● Additional time needed (conventional just from previous crop)
▪ Direct sowing
● Soil type (manual/machine sowing)
● Weed control
● Land efficiency lower
▪ Mini bulb
● Storage
● No clear differentiation between starting material and consumption material
▪ Transplant
● Buying or raising
