In Mexico tomato is of great importance, 70% of the crops grown under protected conditions correspond to tomato; therefore it is important to make an efficient management in intensive agriculture, for this is necessary to understand the factors that determine yield potential of the crop. The aim of this work was to perform a growth analysis of tomato under greenhouse. Two crop cycles of tomato were evaluated during 2011 and 2012. 4 plants per week where removed, to which were determined fresh and dry weight of the different organs. Correlation and regression analysis between the different organs of tomato plant and T Student test between climatic variables of both cycles were performed. With the data obtained, growth curves of different plant organs were generated. It was found that tomato showed an exponential and a linear growth stage. It was shown that there is a strong correlation between fresh and dry weight of different plant organs (p≤ 0.01), and at different growth stages (p≤ 0.01). It was also observed that the generation and accumulation of biomass by tomato plants were affected by the climatic conditions in the greenhouse, since they were different in both cycles (p≤ 0.05). The information in this paper is useful for different factors in tomato under greenhouse conditions.
