Resumo: Corn is a cereal widely consumed worldwide, presenting high production demand. The productivity of green corn is linked to water and nitrogen availability, and knowledge of the interaction between these factors is essential to achieve the best crop yields depending on the edaphoclimatic conditions of a given region. In the present work, we investigated the impact of different water depths (50%, 75%, 100%, 125% of the water replacement of evapotranspiration) and nitrogen doses (0, 70, 140, 210 kg N ha-1), besides the interaction between these two factors on the morphophysiology and production of green corn cv. Agroceres 1051 grown in cerrado of Goiás, Brazil. The different water depths and nitrogen doses did not affect physiological parameters such as net photosynthesis, stomatal conductance, transpiration and fluorescence. Regarding the morphological and production parameters, 125% water depth application increased the length of the ear without straw (CESP), the number of karyopses per row (NCF), stem diameter, green mass of the plant without ear (MVPSE) and the weight of the ear with straw. Fertilization treatment of 210 kg ha-1 of nitrogen increased the length of the ear with and without straw (CECP and CESP), NCF, MVPSE, as well as the diameter and weight of the ear with straw (DECP and PECP). There was a positive correlation between the leaf area (AF) and the productivity parameters. The effectiveness of nitrogen fertilization was limited by water availability for the parameters AF, plant height, number of leaves and length and width of the ear insertion leaf.

La productividad del maíz está relacionada con la disponibilidad de água y nitrógeno, y el conocimiento de la interacción entre estos factores es fundamental para lograr los mejores rendimientos de los cultivos en función de las condiciones edafoclimáticas de una región determinada. En este trabajo, investigamos el impacto de diferentes láminas de riego (50%, 75%, 100%, 125% del recambio hídrico de la evapotranspiración) y dosis de nitrógeno (0, 70, 140, 210 kg N ha-1), además de la interacción entre estos factores sobre la morfofisiología y producción del maíz cv. Agroceres 1051 cultivado en el cerrado de Goiás, Brasil. Los diferentes niveles de agua y nitrógeno no afectaron parámetros fisiológicos como la fotosíntesis líquida, conductancia estomática, transpiración y fluorescencia. Respecto a los parámetros morfológicos y productivos, la aplicación de la lámina de riego de 125% aumentó la longitud de la mazorca sin cáscara (CESP), el número de cariópsidos por fila (NCF), el diámetro del tallo, la masa verde de la planta sin mazorca (MVPSE) y el peso de la mazorca con cáscara. La fertilización con una dosis de 210 kg ha-1 de nitrógeno aumentó la longitud de la mazorca con y sin cáscara (CECP y CESP), NCF, MVPSE, así como el diámetro y peso de la mazorca con cáscara (DECP y PECP). Hubo una correlación positiva entre el área foliar (AF) y los parámetros de productividad. La efectividad de la fertilización con nitrógeno estuvo limitada por la disponibilidad de água para los parámetros AF, altura de la planta, número de hojas, longitude y ancho de la hoja de inserción de la mazorca.Milho-verde é um cereal amplamente consumido no mundo todo, com alta demanda de produção. A produtividade do milho-verde está ligada à disponibilidade hídrica e de nitrogênio, sendo o conhecimento da interação entre estes fatores essencial para alcançar os melhores rendimentos da cultura, dependendo das condições edafoclimáticas de uma determinada região. No presente trabalho, investigamos o impacto de diferentes lâminas de água (50%, 75%, 100%, 125% da reposição hídrica da evapotranspiração) e de doses de nitrogênio (0, 70, 140, 210 kg N ha-1), além da interação entre esses dois fatores sobre a morfofisiologia e produção do milho-verde cv. Agroceres 1051 cultivado em cerrado goiano. As diferentes lâminas de água e dosagens de nitrogênio não afetaram parâmetros fisiológicos como fotossíntese liquida, condutância estomática, transpiração e fluorescência. Em relação aos parâmetros morfológicos e de produção, a aplicação da lâmina de água de 125% promoveu aumento no comprimento da espiga sem palha (CESP), número de cariopses por fileira (NCF), diâmetro do colmo, massa verde da planta sem espiga (MVPSE) e no peso da espiga com palha. A adubação com dose de 210 kg ha-1 de nitrogênio aumentou comprimento da espiga com e sem palha (CECP e CESP), NCF, MVPSE, e o diâmetro e peso da espiga com palha (DECP e PECP). Houve correlação positiva entre a área foliar (AF) e os parâmetros de produtividade. A eficácia da adubação nitrogenada foi limitada pela disponibilidade hídrica para os parâmetros AF, altura da planta, número de folhas e comprimento e largura da folha de inserção da espiga.
