Parameter Description
Scientific name Cucumis sativus
Hybrid F1 Singha 4
Soil It can be sown in variety of soils ranging from sandy loam to heavy soil. But a loamy soil which is rich in organic matter and has well drainage system is best for cucumber farming. The pH ranging from 6-7 is suited best for cucumber farming.
Land Preparation For cucumber plantation, it requires well prepared and weed free field. To bring soil to fine tilth, 3-4 ploughings must be done before planting. FYM is mixed with soil to enrich the field.
Spacing 120*30 cm (stacking), 150*45 cm (Non-staking)
Climate Cucumber requires an ideal temperature of 25-30°C
Season All seasons: Rainy, Winter, Summer
Seed Rate 0.5-0.75 kg/ha

Irrigation In summer season it requires frequent irrigation. Pre-irrigation is required before sowing then subsequent irrigation is required after 2-3 days of sowing. After second sowing, the crops are then irrigated at the interval of 4-5 days. Drip irrigation is very useful for this crop.
Weed Control Manual weeding
Any special crop practices Staking is required for high yields
Diseases
Name of the diseases Symptoms & management
Powdery mildew Characterized by a white, powdery growth on leaves and stems, potentially leading to yellowing, shriveling, and death of affected areas.
Control : Azoxystrobin 23% SC (1ml/L), Sulphur 80% WP (2g/L), Kerahane 48% EC (0.5ml/L)
Downy mildew Causes yellowish-brown irregular spots on leaves, spreading quickly and potentially leading to a gray fungus on the undersides of leaves.
Control : Cymoxanil 8% + Mancozeb 64% WP (2g/L), Fenamidone 10% + Mancozeb 50% (w/w)
Gummy stem blight Affects stems and can cause gummy or watery lesions, potentially leading to plant decline.
Control : Use disease free seeds, crop rotation, paste stem with COC 50% WP 3g/L
Alternaria leaf blight Causes dark, circular lesions with concentric rings on leaves.
Control : Carbendizim 12% + Mancozeb 3% WP (2g/L)
Pests
Name of the pests Symptoms & management
Cucumber beetles Can transmit bacterial wilt and cause feeding damage on leaves.
Control : Acephate 75% SP (1g/L)
Aphids Can transmit viral diseases like cucumber mosaic virus.
Control : Acephate 75% SP (1g/L)
Thrips It will suck the sap from the young leaves leading to leaf distortion.
Control : Fipronil 80% WG @ 0.3 gm/ltr, Thiacloprid 250 SC @ 2 ml/ltr
Fruit Fly Fruit fly causes devastating yield loss in cucumbers. Enter inside fruit causing gummy ooze exudation and disfigures fruit.
Manage: Delegate 1ml/L, Pheromone traps 25-30 traps/Ha
Harvesting Plants start yielding in about 45-48 days after sowing. Mainly 10-12 harvestings can be done. Harvesting is mainly done when the seed of cucumber is soft and the fruits are green and young.
Yield 45-50 t/ha
Parameter Description
Necking Due to improper pollination, poor management.
Control : Improve Honeybee/pollinator activity in the field. Use standard package of practices.
Hollow Heart This disorder appears as a cavity within the fruit, often affecting its texture and marketability.
Control : Avoid excess nitrogen and apply Multinutrient mix @ 12 Kg/Ha.
Fruit Cracking Cracks in the fruit can be caused by rapid changes in water uptake or stress.
Control : Proper irrigation management can resolve cracking.
Light Belly Color The under surface of the fruit remains light instead of turning dark green.
Control : Try to follow staking method of cultivation. Removing the lower leaves about 2 feet height will increase aeration and sunlight.
