Publicación Acceso abierto Patologías asociadas a la deficiencia de cobre y zinc que afectan al ganado bovino(2021-07-15) Lengua Durango, Diana Patricia; Cardona Álvarez, José AlbertoAt present, the study of micromineral deficiency in bovines has been an uncommon topic, and it has not been a specific objective in terms of bibliographic differentiation, but it has had a great boom in terms of type conservation. physiological and behavioral in terms of its pathogenesis and conditions in the reproductive field, so according to a review of a set of mineral studies such as copper and zinc are highly fundamental, and the lack of mineral homeostasis within the bovine organism can cause the presentation of different pathologies related to them, so their study is necessary, so it is possible to conclude that not only the lack of mineral contribution in the case of a research approach (Copper and Zinc) can produce this deficit, but also the presentation of antagonists, which are another set of minerals or compounds that in large quantities do not allow absorption and subsequently block the function of the mineral within the body of the animal causing alterations.Publicación Acceso abierto Respuesta del maíz (Zea mays L.) fnc 2610. a la fertilización foliar complementaria con zinc bajo condiciones edafoclimáticas del municipio Cereté.(2020-11-12) Urango Bravo, Sebastián; Cabrales Herrera, Eliécer MiguelOf the grain cereals, maize (Zea mays L.) is one of the most important due to its participation in food security, in the municipality of cerete its importance is not alien since it contributes not only to food security but also also in the economy of the ceretans, whose soils have high agricultural potential, but fertilization practices are scarce, this is why the need to relate zincbased foliar fertilization with the physiological and crop yield components with the search to improve the growth and development of maize crop. For this, a trial was established in the municipality of cerete, where 3 doses of zinc were evaluated under a randomized complete block design, the variables evaluated were: Plant Height (AP), Number of Leaves (NH), Foliar Area ( AF), Dry Mass, Cob Length (LM), Rows by Cob (HM), Grains by Rows (GH), Weight of 1000 grains (P 1000 G) and Yield (RTO). The general results showed that for the variables of the physiological component AP, NH, AF and MS did not respond significantly to zinc doses, in the same way the variables of the performance component LM, HM, GH, P1000 G and RTO did not have increasing trend with increasing doses of zinc.
