Abstract: A study was conducted to determine the effect of low-tunnel, mulching (black and transparent polyethylene or straw) and pruning treatments on yield and earliness of tomato cv. Fuji F1 in unheated glasshouse. A 643.72% increase in height (relative to height at the planting time) was observed in plants grown under low-tunnel (tunnelled) than those grown without tunnel (602.87%). Among the mulches, plant height increase was highest with the straw mulch (679.13%). Stem diameter increase was higher in plants tunnelled (265.36%) than plants grown without tunnel (233.83%). Straw and transparent polyethylene mulches recorded higher stem diameter than other mulches. The number of days to first harvest was 117.97 for plants tunnelled and that for plants grown without tunnel was 119.88. The shortest time to harvest was recorded in transparent polyethylene (117.90 days), which was at par with black polyethylene (118.17 days). Early fruit yield was higher in tunnelled and mulched treatments than in other treatments. The c
