The Effect of Organic Fertilization (Pigeon and Sheep Manure) on the Productivity of Libyan Beans (Vicia faba L)

Abstract

Faba bean (Vicia faba L.) productivity. in Sirte, Libya, in semi-arid conditions. Using a randomized complete block design, a field experiment was carried out in the 2024–2025 season with three replicates of each treatment: sheep manure (10 t ha⁻¹), pigeon manure (10 t ha⁻¹), and control (no manure). Differences were deemed statistically significant at P ≤ 0.05. Growth traits (plant height, branching, leaf number, leaf area) and yield components (pod number, 100-seed weight, and total yield) were measured and examined using ANOVA. Pigeon manure produced the tallest plants (92 cm), the most pods (16 pods per plant), and the highest seed yield (2.10 t ha⁻¹), outperforming the other treatments by a significant margin. This was a 42 percent increase over the control and a 16 percent increase over sheep manure, according to the results. Sheep manure increased vegetative biomass accumulation, indicating advantages for long-term soil fertility and regrowth, despite being less effective for immediate yield.
