Item Adubação nitrogenada como atenuador do estresse salino em algodão colorido: uma revisão de literatura.(2021-11-29) Souza, Jamiles Carvalho Gonçalves de; Oliveira, Alexandre Campelo de; http://lattes.cnpq.br/8164135937542569; http://lattes.cnpq.br/8445795289858316Cotton is a crop of great economic prominence on the world stage. The commercialization of its fiber in the textile industries, the use of its seeds as raw material in the production of animal feed and vegetable oil, highlights it as one of the most profitable annual crops in the agricultural environment. In Brazil, the Northeast region is one of the largest producers of this crop, with emphasis on the production of colored cotton, where its cultivation is of paramount importance mainly for family farming, and these are the main producers of this fiber. However, the semiarid region has high temperatures and low rainfall concentrated in three months of the year, as a result of which droughts end up occurring more frequently, thus limiting agricultural and livestock activities in the region. The use of irrigation systems helps to increase productivity, however, due to the low quality of water from a high content of salts present in it, there is a metabolic stress that ends up harming the growth and development of crops. In an attempt to alleviate the damage caused by saline water, producers and farmers opt for the use of crops that are more resistant to salinity and even for fertilization techniques, with nitrogen being one of the most used nutrients, as it is required by most agricultural crops. In this sense, the objective was to carry out a literature review to evaluate the effect of different doses of nitrogen and saline water irrigation during the production of colored cotton in the Brazilian semiarid region. Data collection took place on websites of journals and scientific communities, with articles published in Portuguese, English andSpanish, in the areas of plant production and plant nutrition. The deleterious effects caused by the salinity of the irrigation water in the culture of colored cotton for the semiarid region were analyzed, and which nitrogen doses provide a better cotton production under these conditions. Therefore, it is of paramount importance to propagate research information, in the form of articles,on this subject.Item Fracionamento físico do carbono no solo em função da irrigação e adubação nitrogenada(2019) Espindola, Vitor Augusto Silva; Oliveira, Alexandre Campelo de; http://lattes.cnpq.br/8164135937542569; http://lattes.cnpq.br/4334208597286391Variations in the carbon stock are not individual risk factors, these are natural and anthropic, as the natural islands are associated as characteristics of the region, such as climate and temperature of the region, the characteristics of textures, soil C concentrations. The anthropological factor is related to the performance standards of a strategy of changing characteristics of a business that is not before, such as the process of doing its initial business, the struggle for machines and leaching through an irrigation action. Such classes can be occasioned in reducing C concentrations in soil as a problem of soil quality, since this is a resource as a non-renewable resource. Because of this, a number of studies are focused on measuring stock concentrations through practical actions in a way that can lead to loss of inventory. From the total zero hours, from the total hours, from the zero. in the semi-arid region of Pernambuco. The experiment was conducted at the Serra Talhada Academic Unit (UAST) under field conditions, with a randomized block design, evaluation of forage sorghum and millet in consecutive cycles, applied to 4 irrigation slides (28, 36, 44 and 52 %). and 4 levels of nitrogen fertilization (0, 100, 200, 300 kg ha-1). In terms of results, the analysis of the needs of all cycles was made during the first year, showing the potential of applying the local experimental impact in its dynamics. There is a relationship between the COAM and the nitrogen so that an increase of its bases by the provision of soil N alone in the first cycle. There is a reduction in COP concentrations as a first time when doing a man's action when he does not interfere in the other. So, a dynamics of C not having alone in contact with the fact of being under the effect of nitrogen fertilization and irrigation, does not offer significant effects of the interaction between the two on TOC, but rather the action of both managements isolated form. Studies on the higher depths may also be needed because of soil characteristics.
