Evaluating the Adapt‐N model for dynamic nitrogen recommendation in Brazilian maize (Zea mays L.) systems

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Several nitrogen rate recommendation methods have been developed to help farmers fertilize close to the economic optimum N rate (EONR). The objectives of this study were to (i) evaluate a dynamic method (Adapt‐N) for N rate recommendations for maize (Zea mays L.) in Brazil relative to EONRs determined specifically for each trial and (ii ...

Effects of nitrogen fertilizer rate on dry matter yield, nutritive values and nitrate nitrogen of Guineagrass (Panicum maximum Jacq.) extremely late cultivar “Umaku” as a summer annual grass in a warm temperate zone

Grassland Science, Volume 72, Issue 2, Page 151-160, April 2026.
Abstract Cultivation as a summer annual grass in temperate regions of new extremely late‐maturing guineagrass cultivar “Umaku” without heading with fertilizer application entails risks of toxic nitrate nitrogen (nitrate‐N) concentration in the grass.

Acúmulo de macronutrientes e decomposição da palhada de braquiárias em razão da adubação nitrogenada durante e após o consórcio com a cultura do milho

Revista Brasileira de Ciência do Solo, 2014
Em regiões de clima tropical, as principais limitações na manutenção de palhada na superfície do solo são a dificuldade de sua implantação e as suas elevadas taxas de decomposição. Visando identificar o potencial produtivo dos capins xaraés e ruziziensis,

Effects of Urea Fertilizer Levels on Soil Physiochemical Properties and Dry Matter Yield of Hybrid Brachiaria cv. Mulato II Grass in Ethiopia

Applied and Environmental Soil Science, Volume 2026, Issue 1, 2026.
This study assessed the effect of urea fertilizer levels on the dry matter yield (DMY) of Brachiaria cv. Mulato II and on soil chemical and physical properties in Chagni, Amhara, Ethiopia. Urea was applied at 0, 50, and 100 kg/ha, and measurements were taken at 180 days after planting.
