Single and multispecies dual‐purpose cover crop productivity, nutritive value, and profitability

open access: yesAgrosystems, Geosciences & Environment, 2022
Replacing long fallow periods with dual‐purpose forage cover crops increases productivity and profitability of dryland crop rotations. However, little information is available on specific forage cover crops mixtures that optimizes productivity, nutritive

Sulfakinin Signaling Sense Circulating Fructose and Suppresses Food Consumption via Insulin‐Like Peptide in Bactrocera Dorsalis

open access: yesAdvanced Science, EarlyView.
This study discovered a new pathway that tells fruit flies when to stop eating. It found that rising blood sugar (fructose) is detected by a sensor called GR43a. This triggers a chain reaction involving the satiety signal sulfakinin and its receptor, ultimately activating a final satiety signal, ILP5.

Sward structure and nutritive value of Alexandergrass fertilized with nitrogen

open access: yesAnais da Academia Brasileira de Ciências, 2016
This experiment evaluated forage production, sward structure, stocking rate, weight gain per area and nutritive value of forage as grazed by beef heifers on Alexandergrass (Urochloa plantaginea (Link) Hitch) pasture fertilized with nitrogen (N): 0; 100 ...

Forage quality declines with rising temperatures, with implications for livestock production and methane emissions [PDF]

open access: yesBiogeosciences, 2017
Livestock numbers are increasing to supply the growing demand for meat-rich diets. The sustainability of this trend has been questioned, and future environmental changes, such as climate change, may cause some regions to become less suitable for ...

Coordination of Cyanobacterial Nitrate Assimilation and Photosynthesis by a Novel PsbO‐Interacting Protein PirN

open access: yesAdvanced Science, EarlyView.
PirN was identified as a previously uncharacterized PsbO‐interacting protein specifically induced in nitrate‐grown cyanobacteria. Loss of PirN leads to coordinated downregulation of PsbO and the nitrate reductase NarB, causing decreased PSII activity and impaired growth under nitrate conditions. Complementation with either PsbO or NarB largely restores

Boron deficiency responses in maize (Zea mays L.) roots

open access: yesJournal of Plant Nutrition and Soil Science, EarlyView., 2023
Abstract Background Boron (B) is an essential micronutrient for plants. Dicot plants respond to insufficient B supply by altering root architecture and root hair growth. How root systems of rather low‐B demanding monocot species such as maize (Zea mays L.) respond to B deficiency in terra has not been experimentally resolved, yet.

Nutritive value of pastures of Cynodon mixed with forage peanut in southwestern Paraná State

open access: yesActa Scientiarum: Animal Sciences, 2015
This study evaluated the nutritive value of pastures of Coastcross-1 and Tifton 85 mixed with increasing inclusion of forage peanut (0, 25, 50, 75% occupancy area), subjected to cuts, over two study years in Southwestern Paraná State.

Quality Production of Sainfoin Swards Challenged by Global Change in Mountain Areas in the Western Mediterranean

open access: yesAgronomy, 2023
Legume-based livestock forage systems are widespread and socially relevant agroecosystems that are essential for delivering high-quality forage. Therefore, it is critical to determine how climate change and management might affect the functioning of ...

Optimal Grazing Exclusion Duration to Enhance Soil Carbon Sequestration in Degraded Grasslands

open access: yesAdvanced Science, EarlyView.
Across China, grazing exclusion reaches the national mean soil organic carbon recovery benchmark sooner in high‐MAP regions (> 500 mm), but recovery is much slower where MAP < 300 mm. Scaling this strategy to 70% of China's degraded grasslands would sequester about 1.52 Pg of soil carbon over 10 years—roughly 17% of annual global fossil‐fuel emissions.

Allometries in Plants as Drivers of Forage Nutritive Value: A Review

open access: yesAgriculture, 2019
The nutritive value of forage for herbivores has been for a long time determined by the concentration in protein and, hence in nitrogen (N), the concentration in different minerals (P, K, Ca, Mg, and oligo-elements), and the in vivo dry matter (DM ...
