Resumo: | Nitrogen is the most important element required for plant growth and development and is the primary nutrient limiting sugarcane production. Field experiments under rainfed condition and some periods with high temperature (above 35 ºC) were carried out during 2014-2015 at the municipality of Ocampo, Tamaulipas, Mexico. The objective of the study was to determine the effect of varying doses of nitrogen fertilizer on leaf photosynthesis, plant growth, total chlorophyll, and juice quality of sugarcane commercial variety Mex 79-431 in the second ratoon crop. Six nitrogen doses (0, 60, 90, 120, 150, and 180 kg N ha-1) were tested and applied as urea 60 days after harvest, at the beginning of the rainy season. The results of the experiment indicated that the application of nitrogen in ratoon crop had a positive effect on growth and development. It is important to note that further studies are required on the subject, including timing of nitrogen application, application method, soil types, other doses, and other genotypes in the region. The maximum photosynthetic rate (27.68 µmol CO2 m-2 s-1) was attained at PAR 1500 µmol m-2 s-1 with 90 kg N ha-1. The highest yield was recorded in ratoon crop with a dose of 120 kg N ha-1. At harvest, the juice quality did not show significant variations among the treatments imposed. |

O nitrogênio é o elemento mais importante necessário para o crescimento e desenvolvimento das plantas e é o nutriente primário que limita a produção de cana-de-açúcar. Experimentos de campo sob condições de sequeiro e alguns períodos com alta temperatura (acima de 35ºC) foram realizados durante 2014-2015 no município de Ocampo, Tamaulipas, Mexico. O objetivo do estudo foi determinar o efeito de doses variadas de fertilizante nitrogenado na fotossíntese foliar, crescimento das plantas, clorofila total e qualidade do suco na variedade comercial de cana-de-açúcar (Mex 79-431) na segunda safra de soca. Foram testadas seis doses de nitrogênio (0, 60, 90, 120, 150 e 180 kg N ha-1). Todo o nitrogênio foi aplicado como uréia 60 dias após a colheita no início da estação chuvosa. Os resultados do experimento indicaram que a aplicação de nitrogênio na cultura da soqueira teve um efeito positivo no crescimento e desenvolvimento. É importante notar que são necessários mais estudos sobre o momento da aplicação de nitrogênio, o método de aplicação, tipos de solo, outras doses e outros genótipos na região. Os níveis máximos de taxa fotossintética (27,68 µmol CO2 m-2 s-1) foram atingidos a partir de 1500 µmol m-2 s-1 com 90 kg N ha-1. O maior rendimento foi registrado na cultura da soqueira com uma dose de 120 kg N ha-1. Na colheita, a qualidade do suco não apresentou variação significativa devido aos tratamentos impostos.
