ZARAGOZA-ESPARZA, Job et al. Yield and quality of forage of corn hybrids in High Valleys of Mexico. Rev. Mex. Cienc. Agríc [online]. 2019, vol.10, n.1, pp.101-111. ISSN 2007-0934.

Twelve hybrids were evaluated to determine those that exhibit high yields and high forage quality to be used in livestock production. The origin is from the School of Higher Studies Cuautitlan (FESC-UNAM), the National Institute of Forestry, Agriculture and Livestock Research (INIFAP) and the collaboration of both institutions, compared to a commercial control. The research was conducted in the spring-summer cycle of 2013 experiments were established in the Agricultural Teaching Center of the FESC-UNAM and another in the Valley of Mexico Experimental Field (CEVAMEX-INIFAP) of the INIFAP. Each of the experiments consisted of 12 treatments (hybrids), four from the FESC, UNAM, two from INIFAP, five from INIFAP-FESC-UNAM and one control from ASGROW. The PUMA 1163, Buho and H-48 hybrids showed the highest green matter yields (p< 0.05). Buho, 501 x 497, 504 x 408 and PUMA 1163 the highest in dry matter (p< 0.05) and the highest plant height corresponded to the hybrids PUMA 1167 and PUMA 1163 (p< 0.05), so they can be considered alternatives for producers. PUMA 1163 and PUMA 1167 presented high forage quality, with acceptable values of digestibility, protein and low fiber content. In forage quality stood out the hybrids PUMA 1163, H-48 and PUMA 1167 with 63, 61 and 60% of digestibility, respectively. The values for protein, neutral detergent fiber and acid detergent fiber were 8.6 and 8.4%, 60 and 57% and 26 and 22.5% for PUMA 1167 and PUMA 1163, respectively.
