A strategy to increase this demand and reduce environmental impact is the use of wastewater for irrigation in association with mulch, which can bring benefits to the soil microbiota, greater availability of nutrients and agricultural productivity. The objective of this work was to evaluate the abundance and microbial activity in soils cultivated with forage cactus, irrigated with sewage wastewater and with mulch. The experiment was at the Parnamirim Production Unit - PE, using reused water from the sewage treatment plant for irrigation of forage cactus consorted with buffel grass and sudan sorghum. The forage cactus was implanted in double rows 0.5m x 0.5m x 2.0 m, with the cultures intercalated between the double rows, with the experimental unit formed by three double rows of 4 m in length each. Four replications were used in the design in randomized blocks, in factorial arrangement 2 (intercropping with sudan sorghum and buffel grass) x 4 covers (no cover, 8 and 12 tons of corn straw per hectare and natural vegetation). We evaluated soil basal respiration, carbon and nitrogen from soil microbial biomass and metabolic quotient, at 0-10 and 10-20 cm layers. There was no significant difference in soil basal respiration, microbial nitrogen, and metabolic quotient at 0-10 and 10-20 layers. Estimating carbon from microbial biomass at 0-10 cm layer, we observed a significant difference between the intercrops without vegetation cover, however at 10-20 with buffel grass, the 8 tons mulch differed from the other treatments. Even so, further research is necessary to observe these variables over a longer period.Item Avaliação morfológica da cana-de-açúcar (cana-soca) sob condições de estresse salino(2019) Silva, Lívia Maria Cavalcante; Silva, Ênio Farias de França e; http://lattes.cnpq.br/1144266495720148; http://lattes.cnpq.br/6329117330891636Item Automação para o manejo da irrigação na cultura da cana-de-açúcar(2020) Silva, Bruno Felipe Bezerra; Silva, Manassés Mesquita da; http://lattes.cnpq.br/2249840331584869; http://lattes.cnpq.br/6207741248370694Item Hidroponia de baixo custo e fontes alternativas de água na produção de hortaliças(2018) Bartusch, Victor Pedrosa; Santos Júnior, José Amilton; http://lattes.cnpq.br/2839547928353699; http://lattes.cnpq.br/3865227333865612Salinization problems in semi-arid regions make hydroponics a viable crop alternative for agricultural production. In this sense, the objective of this study is to evaluate the water relations of the parsley under different concentrations of salts. Two experiments were carried out in greenhouse, in the Experiment 1, in the factorial scheme (6 x 4) with six salinity levels of the nutrient solution (1.7; 2.7; 3.7; 4,7; 5.7 and 6.7 dS m-1), prepared on the basis of four cationic natures (NaCl, CaCl2, KCl and MgCl2). No experiment I the water of the evapotranspirated blade was replaced with water supply and without experiment II a replacement was made with brackish water based on the cationic natures mentioned above according to treatments. It was verified that with the increase of the electrical conductivity of the nutrient solution, the cationic natures of the water influence the efficiency of water use in the production of fresh and dry mass of the aerial part.Item Atividades Práticas Desenvolvidas em Agroindústria do Setor Sucroalcooleiro do Estado de Pernambuco(2019) Lima, Max Henrique Gonçalves de; Almeida, Gledson Luiz Pontes de; http://lattes.cnpq.br/2328849810614673; http://lattes.cnpq.br/7622040913641513
