Resumo: | The productive sustainability of sugarcane fields depends on adequate nutritional management of sugarcane. Among the nutrients, Nitrogen (N) is the second most absorbed and the one that most limits crop productivity. Leaching losses that occur in sugarcane fields reduce the availability of N for the crop. To meet the need for sugarcane, doses of up to 200 kg ha-1 of mineral N are applied to sugarcane fields, but the recovery of fertilizer N has been limited to 50%. Foliar fertilization can be an alternative to compose more efficient fertilization managements. Whereas, up to 70% of N in the form of N-urea can be recovered by sugarcane within 24 hours. The objective of this work is to evaluate the efficiency of foliar fertilization with N-urea solution in increasing the recovery of N-fertilizer and reducing its leaching losses during sugarcane development. Seven N application managements with doses of 60 kg ha-1, combining reduced fertilization via soil and supplementation on the leaf, plus an extra treatment with application of 120 kg ha-1N via soil, were tested and arranged in three blocks by chance. In the first seven months, N leaching was evaluated. At 162 Day After Planting (DAP), 194 DAP and 224 DAP, the fertilization efficiency, growth and accumulation of aboveground biomass in sugarcane were evaluated. Nitric-N had the greatest participation in the leached solution. The smallest concentrations of N in the leachate and the smallest losses of N by leaching were verified in managements with a dose reduction of 50% (30 kg ha-1) and 25% (45 kg ha-1). In these managements, the N-nitric had greater participation in the leached solution. Foliar fertilization optimized 15N-fertilizer uptake and increased N content and accumulation, biomass production, plant height, and number of internodes. The best responses were identified in the management with a 50% reduction of the dose in the soil with the complementation of two 15 kg ha-1 N applications. In this context, it is concluded that it is possible to reduce the input of N in the soil and complement it via the leaves without compromising the development and accumulation of biomass in the aboveground part of the sugarcane in the sugarcane plant cycle. |

Entre os nutrientes, o Nitrogênio (N) é o segundo mais absorvido e o que mais limita a produtividade da cultura. As perdas por lixiviação que ocorre nos canaviais reduzem a disponibilidade de N para a cultura. Para suprir a necessidade da cana doses de até 200 kg ha-1 de N mineral são aplicadas nos canaviais, mas a recuperação de N-fertilizante tem se limitado a 50%. A adubação foliar pode ser uma alternativa para a compor de manejos de adubação mais eficientes. Visto, que até 70% de N na forma de N-ureia pode ser recuperado pela cana-de-açúcar em 24 horas. Objetivo desse trabalho é avaliar a eficiência da adubação foliar com solução de N-ureia em aumentar a recuperação do N-fertilizante e reduzir suas perdas por lixiviação durante o desenvolvimento da cana-de-açúcar. Sete manejos de aplicação de N com doses de 60 kg ha-1, combinando redução da adubação via solo e complementação na folha, mais um tratamento extra com aplicação de 120 kg ha-1 de N via solo, foram testados e dispostos em três blocos ao acaso. Nos sete primeiros meses foi avaliado a lixiviação de N. Aos 162 Dias Após o Plantio (DAP), 194 DAP e 224 DAP foi avaliado a eficiência da adubação, o crescimento e o acúmulo de biomassa na parte aérea na cana-de-açúcar. O N-nitrico teve a maior participação na solução lixiviada. As menores concentrações de N no lixiviado e as menores perdas de N por lixiviação foram verificados nos manejos com redução da dose em 50% (30 kg ha-1) e 25% (45 kg ha-1). Nesses manejos o N-nitrico teve maior participação na solução lixiviada. As adubações foliares otimizaram a absorção de 15N-fetilizante e incrementaram os teores e acúmulo de N, a produção de biomassa, a altura de planta, e o número de entrenós. As melhores respostas foram identificadas no manejo com redução de 50% da dose no solo com complementação de duas aplicações de N de 15 kg.ha-1. Nesse contexto, conclui-se que é possível reduzir o aporte de N no solo e complementar via foliar sem comprometer o desenvolvimento e o acúmulo de biomassa na parte aérea da cana-de-açúcar no ciclo de cana planta.Submitted by (lucia.rodrigues@ufrpe.br) on 2023-02-15T17:53:18Z No. of bitstreams: 1 Joel Jose de Andrade.pdf: 1982718 bytes, checksum: 26306ffb65880f6415f0fc4a0edafc1b (MD5)Made available in DSpace on 2023-02-15T17:53:18Z (GMT).
