Maize management practices and its relationship with nitrogen indexes and yield
(Spinger, 2025-02-05)Nitrogen fertilization usually increases maize yields, but its impact varies with water availability and plant density. Nitro¬gen indexes like chlorophyll meter readings may help to predict yield variations. Still, their ... -
Post-flowering environment determines zein composition and kernel hardness in maize
(Elsevier, 2025-05)Maize (Zea mays L.) grain endosperm is composed by starch and proteins (mainly zeins, Z1 and Z2) and other minor components. The dry milling industry demands grains with high endosperm hardness, which is determined by both ... -
An evaluation of soil carbon models and their role on finding ways to net-zero carbon in agricultural systems
(Elsevier, 2025-02)The estimation of changes in soil organic carbon (SOC) is a key issue for national green-house gasses (GHG) inventories, climate change mitigation programs and the estimation of carbon footprint of farm products in life ... -
Spatial variability of nitrous oxide emissions from croplands and unmanaged natural ecosystems across a large environmental gradient
(Wiley, 2025-03)Atmospheric nitrous oxide (N2O) is a potent greenhouse gas, with long atmospheric residence time and a global warming potential 273 times higher than CO2. N2O emissions are mainly produced from soils and are influenced by ... -
On the ability of the LR method to detect bias when there is pedigree misspecification and lack of connectedness
(BMC, 2024-11)Background: Cross-validation techniques in genetic evaluations encounter limitations due to the unobservable nature of breeding values and the challenge of validating estimated breeding values (EBVs) against pre-corrected ... -
