MUNDO COXCA, Misael et al. Technological characterization of the production units of tomato under greenhouse in Puebla. Rev. Mex. Cienc. Agríc [online]. 2020, vol.11, n.5, pp.979-992.  Epub Oct 03, 2021. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v11i5.2010.

This work describes the technological characteristics of the tomato production units (UPJ) (Lycopersicon esculentum Mill.) under greenhouse and the socioeconomic characteristics of the producers, in four municipalities of the state of Puebla. The data were obtained from a sample of producers, with a reliability of 95% and precision 10% of the value of the average of the greenhouse surface. 103 producer surveys were applied in the second half of 2017. A technological index (IT) was constructed from variables of technological management and equipment. 25% of UPJ use low technological levels, 66% medium levels and 9% high levels. The explanation of the technological level used by the UPJ was estimated with a Probit interval regression model. The level of education, the experience in greenhouse production and the size of the greenhouse have a significant influence (p≤ 0.5). Therefore, it is concluded that the technological level in the production units, as well as the school level, the cultivated area and the experience in greenhouse production by the producers, are factors closely related to the productivity of the crop. Based on these results, strategies can be developed and implemented to provide advice and training in the proper use of the technologies and equipment necessary to achieve high homogeneous yields in the area.
