Abstract: The study was conducted to investigate the effect of different coloured (black, red and green) plastic mulches on nutrient contents, growth and yield of tomato (Lycopersicon esculentum Mill) variety Indian dwarf. It was observed that total nitrogen contents in plants were significantly higher (4.34%) in the green plastic mulch. The P and K contents in plants were found significantly higher (0.35 and 3.74%) in black plastic mulch. While the N and K contents in fruits showed significant variation among all the mulched treatments but the P contents were found to be non significant. The data showed significant effect on the yield of tomato. The highest yield (28.69 t ha -1) was recorded in green plastic mulch followed by red (22.7 t ha -1) and black plastic (15.84 ha -1) mulched treatments. The study concludes that the green mulch is the best treatment with regard to tomato production.
