Soil

Sandy to sandy loam and medium black soils rich in organic matter with pH range of 6.5- 7.5 is considered as optimum

It is a warm season crop grown adopted to Temperature range of 24o- 27oC is considered as optimum for the growth of the vines.

Season

Rainy: June-Aug
Summer: Feb- April

Seed Rate

1.5 to 2.5 kg/Ha

Fertilizers & Manures

Type	Quantity	Notes
FYM	25 ton/Ha
Nitrogen (N)	200 Kg /Ha	Half the N and entire P & K should be applied before planting. The balance N is given at the time of flowering. The fertilizer is applied in a ring at 6-7 cm from the base of the stem.
Phosphorus (P₂O₅)	25 Kg /Ha
Potassium (K₂O)	100 Kg /Ha
Any special cases : No

Irrigation

Irrigation is given at weekly intervals to keep the moisture well maintained at the root zone, to promote rapid taproot development.

Weed Control

The crop needs 2-3 weeding operations in order to keep if free from weeds. Normally the first weeding is done 30 days after planting. Subsequent weeding is done at a monthly interval.

Any Special Crop Practices

Bitter gourd being a weak climber needs support for its growth. The plants trailed on the support (bower) continues to give yield for 6-7 months.
In bower system, planting is done at a spacing of 2 x 1.5 m. Furrows are opened up at 2 m and irrigation channels are laid out at 5-6 m distance. Wooden poles (3 m in height) are pitched on both the ends of alternate furrows at a distance of 5 m. these poles are connected with wires.
The wires along the furrows are further connected with cross wires fastened at 45cm distance so as to form a network of wires. Seeds are dibbled at distance of 1 m along the furrow and covered lightly with soil. The vines take about 1.5-2 months to reach the bower height, hence the vines during the initial stages of growth are trailed on ropes till they reach the bower. Once the vines reach the bower height, the new tendrils are then trailed on the bower.

Diseases

Name of the Disease	Symptoms & Management
Powdery Mildew	This disease is favored by high humidity, white powdery residue primarily on the upper leaf surface. On the lower surface of the leaves circular patches or spots appear. Severely attacked leaves become brown and defoliation Control: Carbendazim (1ml/litre of water) or Karathane (0.5 ml/litre of water) , tebuconazole 50 % + Trifloxystrobin 25 % @ 0.5 gm / ltr or Meptyl dinocap @ 0.5 gm /ltr
Downy Mildew	Downy mildew is caused by the fungus Pseudoperonospora cubensis. It is prevalent in areas of high humidity and disease is first seen as yellow angular spots on the upper surface of the leaves. Under conditions of high humidity, whitish powdery growth appears on the lower surface of the leaves. The disease spreads rapidly killing the plant quickly through rapid defoliation Control: Metalaxyl 4% + Mancozeb 64 % (2 gm/L), Carbendazim 12 % + Mancozeb 64 % WP @ 2 gm / ltr,
Mosaic	This virus disease produce small irregular yellowish patches are seen on the leaves. Some leaves show vein clearing in one or two lobes of the leaf and severely infected plants show reduction in leaf size and elongation and/or suppression of one or two lobes. Young developing leaves are completely distorted and malformed with considerable reduction in their size. Some of the leaves show marked reduction in the development of lamina resulting in a shoe- string effect. The virus is transmitted by by aphids. Control : Acepahte 20% SP (1g/L)

Pests

Name of the Pest	Symptoms & Management
Fruit fly	Attack fruits. Reddish dark brown flies with hyaline wings, lay eggs under the skin of the fruits; Maggots feed on the pulp of fruits. Infested fruits start rotting and rendered them unfit for human consumption; Fruits show dark-brown, rotten, circular patches and fall off prematurely Control Measures: Clean cultivation, i.e. removal and destruction of fallen & infested fruits daily. Deep ploughing to expose hibernating stages Application of spray baits. 30-35 pheromone traps /Ha
Aphids and White flies	Colonies of nymphs and adults attack leaves and tender shoots and suck the sap; Leaves curl and dry up. Control : Acepahte 75 % SP (1.5 g/L), Dimethioate 1.5ml/L, Imidacloprid 30.5 % SC @ 0.25 ml / ltr, Diafenthiuron 50 % WP @ 1 gm /ltr, 30-35 blue sticky traps / Ha
Leaf Cutter	It will damage the leaves by feeding on it. Control measures : Chloro ( Organophosphate) 20 EC @ 2 ml /ltr
Fruit Borer	Adult moth lays eggs inside the fruit by piercing and after hatching the larva will feed on the flesh and cause fruit damage. Control Measures: Clean cultivation, i.e. removal and destruction of fallen & infested fruits daily. Deep ploughing to expose hibernating stages Application of spray baits. 30-35 yellow sticky traps /Ha

Harvesting

1st harvesting starts 50-55 days after transplanting, further pickings should be done at an interval of 2-3 days as bitter gourd fruits mature very fast and turn red. Harvesting should be done in the morning hours and the fruits should be stored in shade after harvesting.

Yield

35-45 t/ha
