Abstract: A field trial was conducted at instructional farm of Bidhan Chandra Krishi Viswavidyalaya during 2013-14 and 2014-15 to assess the effect of organic mulching and scaffolding as eco-friendly approach for sustainable management of disease and nematode in pointed gourd. The experiment was laid out in Randomized Block Design with seven treatment combinations like paddy straw, water hyacinth, black polythene, rice husk, saw dust, without mulch as control and scaffolding. The results showed that the maximum severity of fruit and vine rot infestation of this crop was recorded in no mulch plots (98.01%) followed by mulching with black polyethylene (93.75) and it was minimum in scaffolding (37.50 %). Control plots recorded maximum percentage of nematode infestation (25.54 %) and lowest in scaffolding (3.44 %). Maximum fresh yield and B: C ratio of pointed gourd (195 q ha-1 and 2.45:1 respectively) were recorded in water hyacinth mulched plots.
