Maximizing Maize Yield: The Impact of Animal Manures on Growth and Productivity

Introduction: Maize (Zea mays L.) is one of the world’s most essential crops, providing food security and economic benefits globally. However, maintaining soil fertility is crucial to ensuring optimal yield. A recent study examines the effects of poultry, sheep, and horse manure on maize growth and productivity. The findings suggest that organic fertilizers, particularly poultry manure, significantly improve maize yield. Visit https://www.plantsciencejournal.org/jpsp for more research in this field.

Effects of Animal Manures on Maize Growth and Yield: The study, conducted in Ethiopia, analyzed various growth parameters, including plant height, number of leaves, leaf area index (LAI), and grain yield. The results indicated that:

• Poultry manure produced the highest grain yield (5.7 t/ha), followed by horse manure (4.2 t/ha) and sheep manure (3.9 t/ha).
• Control plots, which received no organic manure, had the lowest yield (2.8 t/ha).
• Maize plants treated with poultry manure exhibited the tallest height, highest number of leaves, and thickest stems.

Organic Fertilizers vs. Chemical Fertilizers: Unlike inorganic fertilizers, which can lead to soil degradation and nutrient imbalance, organic fertilizers improve soil structure and nutrient retention. The American Society of Agronomy highlights that organic fertilizers enhance microbial activity, leading to long-term soil health and sustainability.

Benefits of Poultry Manure in Maize Cultivation:

• Rich in Essential Nutrients: Poultry manure contains high nitrogen and phosphorus levels, promoting healthy plant growth.
• Improved Soil Quality: Enhances water retention and aeration, leading to better root development.
• Eco-Friendly Solution: Reduces reliance on chemical fertilizers, minimizing environmental pollution.

Strategic Use of Organic Fertilizers: Farmers looking to maximize maize yield should consider integrating poultry manure into their fertilization strategies. Applying manure 30 days before planting ensures nutrient availability throughout the growing season.

Conclusion: This study highlights the significant role of organic fertilizers in improving maize yield. Among the tested manures, poultry manure demonstrated the most beneficial effects, making it a viable alternative to chemical fertilizers.
