What is the recommended sowing density and spacing for Atlas F1?

Recommended plant population is 600 – 1,000 plants/decare with row spacing of 180–200 cm and 80–100 cm within the row. Seeding rate is 0.15–0.25 kg/decare at 20–25 seeds/g. Transplant production requires 40–60 g of seed per decare. When growing under tunnels, spacing may be adjusted to suit tunnel width.

What is the germination temperature for the seeds?

The optimum soil temperature for watermelon germination is 20°C. Transplanting should take place only after soils have warmed reliably – under tunnels this is easier to manage, allowing an earlier start to the season.

What are the main growing risks?

The primary risks for Crimson Sweet type watermelons are fungal diseases in high-humidity conditions, sunscald when foliage cover is insufficient, and fruit cracking from uneven irrigation. Atlas F1 has well-developed foliage that naturally reduces sunscald risk. Drip irrigation with a consistent watering schedule and good tunnel ventilation are strongly recommended.

Is Atlas F1 suited for tunnel production and early market entry?

Yes – at 60 days to maturity it is firmly in the super early category. Tunnel production allows harvest even earlier than open-field growing, which is a key advantage for growers targeting the price premium at the start of the season.

Which market does it target and should grafted plants be used?

Atlas F1 targets the fresh market – wholesale markets, retail chains and direct farm sales. The round shape, attractive rind and consistent weight of 8–10 kg give strong shelf appeal. Grafting onto rootstocks is recommended for intensive tunnel production to improve resistance to soil pathogens and enhance root vigour, but is not required for open-field growing.
