ORTIZ-DIAZ, Sergio Arturo et al. Depth of irrigation tape and solarized manure in the production and quality of forage corn. Rev. Mex. Cienc. Agríc [online]. 2022, vol.13, n.spe28, pp.275-286.  Epub 13-Jan-2023. ISSN 2007-0934.  https://doi.org/10.29312/remexca.v13i28.3282.

The use of organic fertilizers such as bovine manure and subsurface drip irrigation are alternatives that minimize the use of fertilizers and improve water use efficiency. The objective of the research was to evaluate the depth of drip irrigation tape at 0.3, 0.15 and 0.05 m and doses of solarized bovine manure at 50, 75 and 100 t ha-1 and a control with traditional fertilization in the production and bromatological quality in forage corn. The application of manure and the depth of the irrigation tape showed significant differences compared to traditional fertilization. The highest forage yield was for the treatment with a depth of irrigation tape of 0.3 m and 50 t ha-1, on the contrary, the lowest was for irrigation tape with a depth of 0.05 m and traditional fertilization. The manure dose with 75 t ha-1 achieved the highest dry forage production with 22.43 t ha-1. The highest efficiency in water use occurred with the tape depth at 0.15 m. Regarding the bromatological quality, this was higher in the treatments where manure and irrigation tape at depths of 0.15 and 0.3 m were applied. With the use of bovine manure and subsurface drip irrigation, fertilization is decreased and the efficient use of water in the production of forage corn is improved.
