An investigation was carried out in the Department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalainagar, Tamil Nadu during the year 2005-06 to asses the performance of snake gourd for different tillage practices and nutrients under rice fallow condition. The treatments followed were zero tillage, minimum (conservative) tillage and normal tillage with organic manures of FYM (251 ha-1), inorganic fertilizers of NPK (60:50:40) in combination with Vermiwash (1:5) dilution, Panchakavya (3%) and humicacid (0.2%). Normal cultural practices were also adopted for check. The biometric observations viz., vine length, number of laterals per plant, number of leaves per plant, leaf area, leaf area index, chlorophyll content, relative growth rate, photosynthetic rate, dry matter production, number of male and female flowers per plant, fruit yield (t ha-1) and post harvest soil available nutrients NPK (kg ha-1) were recorded for each treatment along with economics of cultivation. The results revealed that the treatment combination of normal tillage+25 t ha-1 of FYM with recommended dose of inorganic fertilizers (60:50:40 kg NPK ha-1)+foliar application of vermiwash (1:5 dilution) T10 was found to be the best with a total yield of 19.21 t ha-1 and a benefit cost ratio of 3.76 which was at par with the treatment combination receiving conservative (minimum) tillage+25 t ha-1 of FYM with recommended dose of inorganic fertilizers (60:50:40 kg NPK ha-1)+foliar application of Vermiwash (1:5 dilution) recorded a total yield of 19.061 ha-1 and more benefit cost ratio of 4.14.
