1.85 Kg per acre in Pits type system of growing generally followed in South India.
5 Kg under furrow type system of growing generally followed in North India.
Seed Treatment and Sowing
Seeds have to be soaked in water before sowing. Seeds are to be treated with Trichoderma viride 4g/kg or Pseudomonas fluorescens 10 gm/kg or Carbendazim 2 gm/kg before sowing. At least 4 or 5 seeds are sown in the pit and after the plants are grown after a period of two weeks, 2 plants which are healthy can be retained to grow further.
Generally the seedlings are grown directly to develop. But there is also practice of raising seedlings in portrays. The portray having 98 cells and plant one seed per cell. Decomposed coco peat is used as medium of planting the seeds. Regular watering two times a day to be ensured. For transplanting, it is necessary to grow the seedlings for at least 12 days in shade before it is planted in main field.
Pits of 60 cm diameter and 30-45 cm depth are taken at 4.5 x 2.0 Meters spacing.
Inter cropping method is beneficial.
Ash Gourd initially grows slow and takes time. It is advisable to raise quick growing Cucumber or Oriental pickling Melon as inter crop so as to get additional benefit.
Watering every third day is required in the initial stage and further it is to be increased to every alternate day during flowering and fruit formation.
Initially during ploughing just before last ploughing, apply Farm yard Manure at the rate of 120 Kg and Neem cake 240 Kg along with Azospirillum and Phosphobacteria at the rate of 5 Kg and Pseudomonas at the rate of 6 Kg per acre.
Apply Farm Yard Manure 10 Kg per pit as basal. Basal application of N-P-K as 10-10-10 kg per acre is recommended. N at 10 kg per acre may be repeated one month and two months after sowing.
Weeding and soil loosening to be done at the time of fertilizer application.
