Resumo: The aim of this study was to evaluate microbial biomass and total organic carbon and nitrogen of an irrigated Quartzarenic Neosol cultivated with two cowpea cultivars in Bom Jesus, Piauí, Brazil. The experiment was conducted in a randomized experimental block design in split plots. The plots consist of two cowpea cultivars (Aracê and Tumucumaque) and the subplots were composed of five different irrigation regimes (L1 = 108.2; L2 = 214.7; L3 = 287.9; L4 = 426.1, and L5 = 527.7 mm). Soil samples were collected at a depth of 0-0.20 m in order to evaluate basal soil respiration, microbial biomass carbon, metabolic quotient, microbial quotient, content, and storage of soil carbon and nitrogen. Basal soil respiration, microbial biomass carbon, microbial metabolic quotient, and microbial quotient are influenced by the interaction between cowpea cultivars and irrigation. The cultivar Aracê showed greater stimulus to the microbial community, while the irrigation regimes with 214.7 and 287.9 mm (60 and 90% of ETo, respectively) provided the best moisture conditions for microbial activities.

O experimento foi instalado em delineamento experimental em blocos ao acaso dispostos em parcelas subdivididas, sendo as subparcelas cinco lâminas de irrigação por aspersão (L1=108,2; L2 = 214,7; L3 = 287,9; L4 = 426,1 e L5 = 527,7 mm) e as parcelas duas cultivares de feijão-caupi (Aracê e Tumucumaque). Foram coletas amostras de solo na profundidade de 0-0,20 m para as avaliações da respiração basal do solo, carbono da biomassa microbiana, quociente metabólico, quociente microbiano, teor e estoque de carbono e nitrogênio do solo. A respiração basal do solo, carbono da biomassa microbiana, quociente metabólico e quociente microbiano são influenciados pela interação entre cutivares de feijão-caupi e lâminas de irrigação. A cultivar Aracê apresentou maior estímulo a comunidade microbiana, enquanto as lâminas de irrigação com 214,7 e 287,9 mm (60 e 90% da ETo, respectivamente) proporcionaram as melhores condições de umidade a atividade microbiana.UEL2017-08-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2646510.5433/1679-0359.2017v38n4p1765Semina: Ciências Agrárias; Vol. 38 No. 4 (2017); 1765-1774Semina: Ciências Agrárias; v. 38 n. 4 (2017); 1765-17741679-03591676-546Xreponame:Semina.
