Fruit and vine rot of pointed gourd (Trichosanthes dioica) caused by Phytophthora melonis Katsura is a potential disease that occurs extensively in major pointed gourd growing regions of the country. In order to record the effect of planting systems on the incidence and severity of this disease, a study was conducted under trellis and soil bed system of planting during 2015. The study revealed that crop grown in soil bed system had exhibited the vine and fruit rot to the tune of 34.8 and 39.0 percent, respectively during peak rainy season. In trellis system during the study period, there was no fruit and vine rot incidence, however, leaf blight severity to the tune of 2.8 percent was observed as against 28.8 percent in soil bed system. Only the leaf blight was confined to lower most leaves in trellis system. Disease severity was more in soil bed system in rainy season as against other season. Nearly, 40% mortality was observed in seedlings prepared from cuttings taken from soil bed system. Hence on based this study, it was concluded that pointed gourd crop grown on trellis can potentially reduce the leaf, vine and fruit rot severity especially when cropping period coincides with rainy season.
