This video from the Mon Système Fourrager channel explores the impact of environmental factors on the nutritional quality of silage maize.
Key points:
Impact of temperature:
High temperatures during pollination reduce grain production and starch quality.
High temperatures during fermentation increase the pH and decrease the production of lactic acid, affecting the preservation of the fodder.
Impact of water stress:
Water stress at the leaf release stage and at the R2 stage (grain development) causes the greatest yield losses.
Water stress reduces the digestibility of the plant.
Impact of light:
Low light intensity decreases the fiber content in maize.
High light intensity can increase yields and starch content.
Impact of diseases and insects:
Diseases and insects can affect grain quality and reduce yields.
Impact of hail:
Defoliation by hail at the pollination stage seriously affects yield.
Defoliation at other stages has less of an impact.
Conclusion:
Environmental factors such as temperature, water stress, light, light, diseases, insects, and hail play a crucial role in the nutritional quality of silage maize. It is important to understand these impacts in order to optimize the production and conservation of fodder.
