Nitrogênio e água como fatores de produtividade do trigo no cerrado
Visando avaliar os efeitos do manejo da irrigação e de doses de nitrogênio na produtividade de duas cultivares de trigo e seus componentes, conduziram-se dois experimentos na Embrapa Arroz e Feijão, em Santo Antônio de Goiás, GO, em plantio direto, na palhada da cultura da soja em um dos quais o rei...

Abstract | Visando avaliar os efeitos do manejo da irrigação e de doses de nitrogênio na produtividade de duas cultivares de trigo e seus componentes, conduziram-se dois experimentos na Embrapa Arroz e Feijão, em Santo Antônio de Goiás, GO, em plantio direto, na palhada da cultura da soja em um dos quais o reinício da irrigação se dava na tensão matricial de 40 kPa e, no outro, na de 60 kPa. O delineamento experimental em ambos os experimentos foi o de blocos ao acaso, com parcelas subdivididas e quatro repetições. Nas parcelas foram estabelecidas cinco doses de nitrogênio em cobertura: 0, 50, 100, 150 e 200 kg ha-1 e, nas subparcelas, as cultivares EMBRAPA 22 e EMBRAPA 42. A tensão matricial de 60 kPa foi mais adequada para o manejo da irrigação no trigo, de vez que não afetou sua produtividade nem a qualidade mas utilizou menor lâmina total de água. A dose de nitrogênio em cobertura que proporcionou a máxima eficiência técnica, foi de 73 kg ha-1. O teor de proteína bruta aumentou com o incremento de nitrogênio, enquanto o incremento da freqüência de irrigação e de nitrogênio diminuiu o peso hectolítrico.
Two experiments were carried out at Embrapa Rice and Beans, located at the municipality of Santo Antônio de Goiás, Goiás state, Brazil, under no-tillage in the soybean straw, to evaluate the effects of irrigation management and nitrogen doses on the grain yield and its components of two wheat cultivars. In the first experiment, the irrigation was started at soil-water tension of 40 kPa, and in the second one, at soil-water tension of 60 kPa. For both experiments, a randomized block design with subdivided plots, with four replications, was used. In the plots were established five doses of nitrogen (0, 50, 100, 150, and 200 kg ha-1) and, in the subplots, the cultivars EMBRAPA 22 and EMBRAPA 42. Soil-water tension of 60 kPa was more adequate for management of irrigation in wheat, since it did not affect its grain yield and quality and used less water. The dose of nitrogen that promoted maximum technical efficiency was 73 kg ha-1. The crude protein content increased as nitrogen increased. The increase of irrigation frequency and nitrogen decreased the hectoliter-grain weight. |
