Selection of the field/land preparation practices

Land selection - Soils with good nutrition (medium soil, loam to sandy loam). The soil must be having excellent drainage history.Land should be well prepared.  1-2 deep ploughing followed by 3-4 rounds of harrows to get fine tilt. Before final harrow, apply 8 to 10 MT well decomposed FYM/acre along with 1kg Trichoderma for controlling soil born fungus.

Seed Treatment-rate of timing/ chemical

Seeds are treated with Carbendazim 2g + Thiram 2 g per Kg of seeds.

Sowing Time

Late Winter, Early Summer, Summer

Seed Rate/ Sowing method- line sowing with row to row and plant to plant distance/ direct sowing

 

Sowing / Transplanting Methods: In this case the seedless watermelon seeds are never sown directly on field. It is recommended to grow the seed in tray and should be transplanted at 4 leaf stage in the main field. Nursery Management -

  • Seedless watermelon generally has hard seed coat, should be grown with professional YPR, complete protocol needs to be followed.
  • Seedless and Seeded Sowing should be done in staggering of 5-8 days (Seedless First)
  • Tray should be of Cavity square – 2.5 to 3.1cm square 
  • The coco-peat could be as rough/granular as possible for Seedless WM

 Seed Rate: 200gm seedless and 100gm seeded per acre. (Apx. 4000plant seedless and 2000plant seeded) Spacing:

  • Row to Row and Plant to Plant – 120 × 30 cm (Single Row) or 240 × 30 cm (Double Row)
  • Seedless and seeded must be done in 2:1 ratio. (2 rows seedless and 1 row seeded) Seeded at Border lines.

Pollination Management:

  • Seedless watermelon does not produce pollens hence pollinators (Seeded WM) are planted.
  • The pollens are transferred from seeded to seedless flowers by bees.
  • In general, 2-3 hives are required per Acre. Keep beehives in shade with water in shallow pot.
  • The bees are diploid when 25% of plants have flowers.
  • Do not spray during peak pollination period.
  • More than 24 visits are required of bees for successful pollination

Fertilizer dose with timing

Total N:P:K requirement @ 80:100:120 kg per acre.Dose & Timing:Basal Dose: Apply 50% N and 100% P, K as basal dose during final land preparation.Top Dressing: 25% N at 30 days after sowing and 25% N at 50 days after sowing. Fertigation Management

Weed Control- Chemicals with doses and timing

For watermelon cultivation hand weeding is suggested. There can be 2-3 weeding before early fruit formation stage. After that, it is advised to restrict labour movement in the field so as to achieve less damage to crop and no disturbance to honeybee activities. In India herbicides use is not yet in practice.

Diseases & Pest control- Chemicals with doses and timing

For effective crop control apply fungicide as per recommendation from the Department of Agriculture (plant protection) to control Damping off, Downey Mildew, Powdery Mildew and other fungal diseases. Apply recommended insecticide to control sucking pest, fruit fly and any other insects.Insecticide spray should not be done at flowering stage (25 - 45Days) to enable honeybee activities for pollination. For watermelon crop leaf minor, thrips and the fruit fly are major insects. While Downy Mildew, Powdery Mildew, Wilt, Anthracnose and Gumy Stem Blight are the major diseases. Timely control of insect and diseases will help to achieve excellent crop growth. Do not spray during peak pollination period.

The schedule is as per label available for wm

Other than this use VF for leaf minor @ 12-15 dat (also use it in nursery)

Use good chemistry to control Thrips

Irrigation Schedule

Irrigation management is very crucial in watermelon cultivation. Looking to the soli type and season, irrigation frequency and quantity can be decided. Drip irrigation system is strongly advised for this crop. After fruit setting irrigation interval needs to be fixed and maintained. Sudden change in irrigation frequency after fruit set can cause fruit busting and hollow heart. The moisture level needs to be maintained at optimum level.

Harvesting

Harvest the fruit at the time of physiological maturity. Date of maturity or days after transplanting (65-70 days for seedless and 70-75 days for seeded) Maturity of watermelon can be judged by the following steps:1.A dead tendril attach to the vine2.Dull appearance of the fruit compared to their slick appearance3.Narrowing of the rind strips towards the head end.4.Maturity is also judged by metallic sounds5.After harvesting fruits should not be left long in the sun otherwise sun scaled may develop Note - Seedless watermelon harvesting should be done 2-3 times and Seeded can be done 1-2 times

Expected Yield of the variety

Average yield:  20-24 mt Seedless and 8 -10 mt Seeded /acre (depending on season and crop management practice)
