Off-season cultivation of bitter gourd in plains 

Bitter gourd is also known by many names like karvellak, karvelika, karel, kareli. Generally, hot weather is required for the cultivation of bitter gourd. It can be grown in summer as well as in rainy season. A temperature of 25 to 35 degree centigrade is considered good for bitter cultivation. The temperature should be 22 to 25 degrees for the germination of seeds. Bitter gourd cannot be cultivated in the open field during winter season, but farmers of urban areas and villages near the market can cultivate bitter gourd in winter season also with the help of polyhouse technique. The Bitter crop starts perishing quickly, so farmers can earn profit by selling it early when it is near the market. In the plains, sowing is done in September for the cultivation of bitter crop using polyhouse technique. It is cultivated by making beds.

Farm preparation in polyhouse 

For the cultivation of bitter gourd in polyhouse, first, tall and tall beds are made and levelled. Then 5 kg of dung compost or vermicompost manure is mixed in it per square meter. Also, 2-4 ml of formaldehyde or two spoons of carbendazim is dissolved in per litre of water, sprinkled in the field and mixed well, then the field is covered with plastic for two weeks. Due to this, there will be no risk of pests and diseases in the soil and there will be good production of the crop.

Temperature inside the polyhouse
