Resumo: | The effects of biochar and nitrogen application on yields of upland rice and cowpea and on soil fertility were determined in a greenhouse in Macaíba, RN, Brazil. The trial consisted of the succession of two crops in a completely randomized design and a factorial scheme, with four replicates. Initially, four doses of biochar and four doses of nitrogen were tested for cultivation of rice. Subsequently, four doses of biochar and two doses of nitrogen were tested in half of the pots maintained for planting cowpea. Soil was sampled after rice harvest for half of the pots and at end of the trial for the remaining pots. We evaluated the following parameters: mass of hundred grains of rice, dry shoot mass, panicle number, number of filled spikelets and of empty spikelets, and grain production. Determinations for cowpea were: pod number per pot, grain number per pod, and grain production per pot. Measured soil parameters were: pH, contents of organic carbon, P, K, Ca, Mg, Na, cation exchange capacity, and exchangeable sodium percentage. Biochar addition did not influence yield components of upland rice and cowpea, but resulted in increased soil N retention, which influenced rice dry shoot mass, spikelets sterility, panicle number, and grain mass. Biochar also promoted increased soil pH, potassium content, and exchangeable sodium percentage and decreased calcium and magnesium concentrations. |

O experimento constou de dois cultivos sucessivos em delineamento experimental completamente casualizado em arranjo fatorial, com quatro repetições. Inicialmente, foram testadas quatro doses de carvão vegetal e quatro de nitrogênio para a cultura do arroz. A seguir, foi cultivado feijão-caupi em metade dos vasos (quatro doses de carvão e duas de nitrogênio). O solo foi amostrado após a colheita do arroz, em metade dos vasos, e ao final do experimento, nos vasos restantes. Do arroz foram determinados, massa de cem grãos e, por vaso, massa seca da parte aérea, número de panículas, número de grãos cheios e grãos vazios e produção de grãos. Do feijão-caupi foram determinados: número de vagens por vaso, número de grãos por vagem e produção de grãos por vaso. No solo foram determinados: pH, teores de carbono orgânico, P, K, Ca, Mg e Na, capacidade de troca de cátions e percentagem de sódio trocável. As doses de carvão vegetal não influenciaram nas características de produção do arroz e feijão-caupi, mas favoreceram a retenção de nitrogênio no solo, que se refletiu sobre massa seca da parte aérea do arroz, esterilidade das espiguetas, número de panículas e massa dos grãos. Além disso, promoveram aumento no pH, teor de potássio e percentagem de sódio trocável do solo, com diminuição no teor de cálcio e magnésio.Universidade Federal Rural do Semi-Árido2017-01-24info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/449710.1590/1983-21252017v30n206rcREVISTA CAATINGA; Vol. 30 No. 2 (2017); 313-323Revista Caatinga; v. 30 n. 2 (2017); 313-3231983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/4497/pdfMiranda, Neyton de OliveiraPimenta, Alexandre SantosSilva, Gualter Guenther Costa daOliveira, Ermelinda Maria MotaCarvalho, Mary Anne Barbosa deinfo:eu-repo/semantics/openAccess2023-07-20T10:52:10Zoai:ojs.periodicos.ufersa.edu.br:article/4497Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:16.528553Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true |
