To lessen this negative occurrence, moisture availability provides better performance for the species, such as using hydrogel instead of irrigation. The objective of this study was to evaluate the effect of using hydrogel polymers on the production of cactus pear (<em>Opuntia stricta</em> cv. Mexican Elephant Ear). Three treatments with six replications were used, totalling 18 experimental units. The treatments were, (1) Conventional fertilization using fertilizer in granulated format; (2) Foliar fertilization with polymer using a dilution dose of 6 grams of polymer L<sup>-1 </sup>of water associated with the fertilizer in liquid form through the foliar route; (3) Foliar fertilization without polymer using only foliar fertilization in the same formulation as the treatment with polymer. There was no effect of fertilization strategy on plant height, cladode length, cladode width, cladode thickness, cladode area, and biomass. There was an effect of the fertilization strategy on dry matter, in which higher estimates were measured for conventional fertilization and foliar fertilization without polymer. On the other hand, foliar fertilization with polymer promoted increases of 13% in mineral matter and 42% in crude protein in relation to conventional fertilization. The fertilization strategy did not change the other chemical attributes of cactus pear. The use of the hydrogel did not influence the morphometric development of the Mexican Elephant Ear cultivar but promoted increments in the chemical composition.</p> Pablo Ramon Costa, Emerson Moreira de Aguiar, Antonio Leandro Chaves Gurgel, Patrick Bezerra Fernandes, João Virgínio Emerenciano Neto, Murilo dos Santos Ferreira, Williana da Silva Melo, Gelson dos Santos Difante, Luís Carlos Vinhas Ítavo, Tairon Pannunzio Dias-Silva, Marcos Jácome de Araújo, Larissa de Oliveira Fontes, Maíra Vieira Ataíde, José Henrique da Silva Taveira Copyright (c) 2024 Journal of the Professional Association for Cactus Development https://www.jpacd.org/jpacd/article/view/535 Fri, 23 Feb 2024 00:00:00 +0000 Agronanotechnology in the arid zones of northern Mexico: Research, challenges, and new trends https://www.jpacd.org/jpacd/article/view/534 <p>The agri-food systems in arid zones face challenges related to climate change, desertification, and soil contamination from agrochemicals' actions, among others. The agronanotechnology can generate alternatives to these problems, but it is necessary to monitor its development to have elements to apply policies that are oriented to the attention of these regions with a social perspective. This scientific paper aims to present provide a study of the situation of agronanotechnology in the arid zones of northern Mexico. Using bibliometric tools, the academic output in the field and map the public research agenda, focusing on providing the set of crops to which the local research is directed was analyzed. Furthermore, the literature associated with the risks to human health and the environment derived from some nanomaterials of agri-food interest and clarify the areas of opportunity and trends was reviewed. The results show a total of 224 research articles authored by 1029 scholars in 161 journals published from 2004 to 2022; that research on this topic reached its highest value in 2018 and then levels off at a value around of ~37%. The findings show a research agenda related to crops of economic interest for the export market like tequila, tomato, avocado, chili, watermelon. In México, agronanotechnology is an emerging field that deals with some crops of economic interest, but its development needs to be intertwined with the needs of rural producers<strong><em>.</em></strong></p> Mónica Anzaldo-Montoya, Yoscelina Iraida Hernández-García, Luis Guillermo Hernández-Montiel, Luis Hernández Adame Copyright (c) 2024 Journal of the Professional Association for Cactus Development https://www.jpacd.org/jpacd/article/view/534 Fri, 19 Jan 2024 00:00:00 +0000
