Improved Trellis System in Cucurbitaceous crop

Farmers usually grow Cucurbitaceous crops with bamboo or branches of forest tree as staking material which is not easily available and costly these days. There is also pressure on nearby forest areas. Moreover, due to irregular trailing and less duration of these trellis materials often crop growth is affected and duration of crop shortened. There is more pest and disease incidence which ultimately affects the yield. Therefore, to overcome the problem, demonstration programme on improved trellis system in Bitter gourd & Snake gourd using nylon net has been demonstrated under RESILIENCE PROJECT in Ganjam district project villages in 02 ha area during 2020-21 and 2021-22. With this improved trellis system, the downy mildew disease decreased by 70% & the number of female flower/plant increased by 21%.  The vegetable yield of 142.6 Q/ha was obtained with benefit to cost ratio of 2.37.    The detailed economics is given as below:
