Effect of spacing on yield and yield attributing characters of tomato was studied under low cost naturally ventilated greenhouse during the winter season of Tamil Nadu in M.S.Swaminathan Research Foundation, Chennai. One month old seedlings of tomato (cv. PKM 1) were transplanted at four different spacings (75 x 60 cm, 60 x 45 cm, 45 x 30 cm, and 30 x 15 cm) in a low cost naturally ventilated greenhouse. Effects of different spacing on the plant height, number of nodes, internode length, plant dry matter, number of fruits, average fruit weight and yield of tomato were assessed. The results showed that increasing the spacing significantly increased the number of fruits, average fruit weight, yields per plant and dry matter. It was found that the highest fruit yield was recorded in wider spacing of 75 x 60 cm followed by 60 x 45 cm spacing.
