Field trials were carried out in 2013-2014 cropping seasons to assess the impact of different mulching materials on the growth and yield of tomato (Solanum lycopersicum) in Dehradun (Uttarakhand) region of India. The crop growth and fruit yield were studied for two cultivars namely Cherry Tomato and Marglobe under two inorganic mulches (black polythene, white polythene) and four organic mulches (FYM, rice straw, dry leaves, sugarcane trash) and compared with unweeded control. Four competitive plants were randomly selected from each treatment to record data on various parameters. The experiment comprising these treatments was laid out as factorial randomized block design with three replications. It was observed that among all the treatments black polythene mulch showed significantly higher plant height (89.92 cm, 59.17 cm) and (97.17 cm, 63.42 cm) after 30 and 45 days respectively, number of trusses per plant (109 and 6.33), number of fruits per truss (14.50 and 6.42) and weight of immature and mature fruits (4.59 gm and 6.73 gm) and (42.08 gm and 54.25 gm) in Cherry Tomato and Marglobe varieties. Among all the treatments, black polythene mulch was found to be the best for tomato cultivation in Dehradun (Uttarakhand) region of India.
