SOLORIO ELIZALDE, Nahielli; PAZ PELLAT, Fernando; ODI LARA, Magali  e  BOLANOS GONZALEZ, Martín A. Expolinear growth model and productivity equivalence of a greenhouse grown tomato. Terra Latinoam [online]. 2009, vol.27, n.2, pp.143-151. ISSN 2395-8030.

The vegetation expolinear grown model in the vegetative stage has been proposed as a semi-empirical scheme for modeling, where acceptable results are obtained when applied to experimental data. In this paper, this model is reviewed in its general form and applied to a greenhouse tomato under a combination of different levels of water stress and nitrogen. The results show that the adjustments of the model are good for aerial dry matter and foliar area, validating in this form its use for conditions away from the optimum. Also, the environmental equivalence in productivity concept is discussed and reviewed using experimental data, where good results were obtained in its applicability, defining a way of modeling the growth of very compact vegetation.
