Cost-Effectiveness Analysis of Fertilizer Input on Sorghum Productivity in Tahtay Adyabo, northwester Tigrai

Abstract

This study evaluates the cost-effectiveness of various fertilizer inputs on sorghum productivity in Sheraro, Northwestern Tigray. Sorghum (Sorghum bicolor) plays a vital role in Ethiopian agriculture, serving as a staple food and a key source of income for many households. Utilizing a mixed-methods approach, this research examines the impact of different types of fertilizers organic, inorganic, and blended on yield outcomes, economic viability, and soil health. Key findings indicate that nitrogen-based fertilizers are predominantly used among farmers, yet a significant interest in organic options is emerging. The economic analysis reveals that integrated nutrient management practices can enhance productivity while promoting sustainability. This study provides practical recommendations for farmers, aiming to improve their fertilizer use efficiency and inform agricultural policy decisions. By addressing the gaps in knowledge regarding fertilizer effectiveness and its economic implications, this research contributes to the ongoing efforts to enhance agricultural productivity and food security in Ethiopia.
