By simple be the development and growth of tomato plant there are links of other variables that allow such as:
temperature, sunlight, nutrients and substrate or soil. Mexico has a great diversity of climates by what these crop
yields vary depending on the level of applied technology (greenhouses, mesh-shadow or Mac), conditions of
light, temperature and substrate or soil in which to develop [1]. Cultivation is determined by the direction of
growth, to assess the growth of leaf area weekly. To determine the growth of this, you may experience through two crop cycles; therefore sampling should be held sequentially with trials repeated weekly, which would allow
the application of the model of Markov chains. Paegelow mentions that Markov chains simulate the prediction
of the State of a system at a time determined from two from States, i.e. that does not consider the descriptive,
and explanatory variables, but it is based solely on the analysis of the internal dynamics of the system. In the
study of the growth of leaf area apply Markov chains, determining the functions of the variables which link the
growth of tomato in its phenological stages, established by weekly surveys on the development of plants, so it is
essential to establish a transition matrix, this being a stochastic process used to study phenomena from an initial
state, passing through a sequence of States, where a particular State transition occurs according to a certain
probability [2]. Above, are carried out two experimental trials in the cycles of production, spring-summer and
autumn-winter determining growth leaf area in red tomato type “Saladette” under greenhouse conditions.
