The effect of changes in microclimate produced by poly greenhouse conditions on plant growth characteristics and fruit yield of tomato was studied during 1999 in experiments conducted at the Ecohorticulture farm of M. S. Swaminathan Research Foundation located at Tamil Nadu Livestock Research Station, Kattupakkam, Kancheepuram district, Tamil Nadu. UV stabilized plastic film covered greenhouse recorded higher day temperature than the open environment but relative humidity at 8 am was lower inside the greenhouse except from May to August. The light intensity inside the greenhouse was lower than in the open. Height of the plant, number of nodes, internodal length total dry matter production and average fruit weight increased under greenhouse conditions as compared to open field condition. The yield performance inside the greenhouse was highest 2145 g/plant and 2156 g/plant in the first and second season, respectively) than the open field crop. The fruit yield inside the greenhouse was nearly two times more than in the open field condition.
