Effect of variations in solid and liquid organic compost on the plant growth of leek (Allium porrum L.)

Year: 2025

Type: article

Abstract: This study examined the effects of various combinations of solid compost, liquid extract-compost, and inorganic fertilizers on the growth and nutrient uptake of leek (Allium porrum L.).The objective was to identify the most effective nutrient management strategy to enhance crop performance.Solid compost was produced from cattle manure, and liquid extract-compost was prepared through aqueous extraction and aeration.Six treatment groups with different nitrogen (N) applications were designed, including pure organic and integrated organic-inorganic combinations.Results revealed that 3/3N solid compost significantly improved early plant height and leaf yield.However, the combination of 2/3N solid compost with 1/3N inorganic fertilizer achieved the highest total biomass and nitrogen-use efficiency (NUE).Treatments with higher liquid compost application exhibited initial growth suppression due to ammonium toxicity but gradually improved over time.These findings highlight the importance of balanced nutrient management in maximizing crop yield and ensuring sustainable farming practices.
