GONZALEZ-BETANCOURT, María de Lourdes et al. Solarized bovine manure in tomato production under shade mesh conditions. Rev. Mex. Cienc. Agríc [online]. 2020, vol.11, n.2, pp.253-262.  Epub 15-Mar-2021. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v11i2.2299.

In organic agriculture, the resources available in the region are used sustainably in order to reduce production costs, especially those related to fertilization. The use of organic fertilizers is an alternative for achieving this purpose. The objective of the present work was to evaluate the effect of solarized bovine manure on the production and quality of tomato fruits. A randomized block design with six repetitions was used; the treatments were four doses of solarized manure (0, 40, 80, 120 t ha-1). There was no significant difference for the variables plant height, number of fruits and yield between the different doses of manure, however, with the application of 120 ton ha-1 the content of β-carotene and anthocyanins was increased by 60.14 and 64.17%, compared to the witness, respectively. Significant differences in soil pH and EC were recorded at the end of the crop cycle. The use of solarized manure is a sustainable option for the production of tomato in shade mesh, since similar results were obtained without the application of inorganic fertilization.
