VAZQUEZ MENDOZA, Paulina et al. Nopal clones Oreja de Elefante Mexicana with forage potential. Rev. Mex. Cienc. Agríc [online]. 2020, vol.11, n.spe24, pp.231-237. Epub 07-Mayo-2021. ISSN 2007-0934. https://doi.org/10.29312/remexca.v0i24.2373.
In order to evaluate, among clones of the Oreja de Elefante Mexicana nopal cultivar (Opuntia stricta Haw), the one that indicated agronomic and zootechnical characteristics to be considered with forage potential, an experiment was carried out at the Agronomic Institute of Pernambuco (IPA), located at coordinates 08° 25’ 15’’ south latitude and 37° 03’ 41’’ west longitude, at 663 meters above sea level, with a precipitation of 692 mm. The experimental period was from January 2014 to July 2015 and the clones used were Lisa 1, Lisa 2, Seg CV, mãe plant, Seg 1, Seg 2, Seg 3, Seg 4, Seg 5 and Seg 6. The variables evaluated were production (t DM ha-1), number of cladodes in plant (NC), plant height (PH), plant width (PWI), amount of thorn (AT), size of thorn (ST) and amount of gloquide (AG); within each plant it was measured in cladodes, perimeter (P), length (LC), width (WID) and thickness (TH), number of lines (NLI) and number of buds (NBU). The experimental design was completely random and the test of comparison of means with Tukey (p≤ 0.05). There were differences between clones (p≤ 0.05); Lisa 2, showed the lowest AT, ST, AG, and the lowest production (6.45 t DM ha-1), the Seg CV clone, showed higher production (67.41 t DM ha-1), NC, PH, and PWI, without However, it also presented higher AT, ST and AG, so despite its yield it does not show the best agronomic and zootechnical characteristics.
