The Analysis of Fertilizer use and Agricultural Productivity: (case of La’ilay Maychew Woreda, Tigray, Ethiopia)


This study tried to analyze the effect of inorganic fertilizers on farm productivity and identify the factors that influence probability and intensity of adoption of inorganic fertilizer with a research question of “Does the marginal effect of fertilizers is significantly high? The study was conducted in Woreda La’ilay Maychew, central Tigray, Ethiopia on Farm productivity and yield of the small holder farmers.

The role of the agricultural sector in terms of its contribution to the study area’s economy is immense. Further, the success and failure of the economy is highly correlated to the performance of this sector. To accelerate the sector’s growth and increase its contribution to the overall economic growth the application of modern inputs particularly inorganic fertilizers in the sector plays a great role.

The starting point for this research work was the farm investment theory of Feder, Just, and Zilberman who analyses technology adoption and productivity growth. The multi-stage sampling method was used to select both villages and respondents. A total of 131 plots from four peasant associations were used for the analysis.

The first estimated model was Cobb-Douglas production function. It was found that fertilizer is positively and significantly impacted agricultural productivity. In addition, other results from this multivariate regression analysis shows that age of head, labor, livestock and land have a positive and statistical significant effect.

Factors influencing the extent and intensity of fertilizer adoption on major cereals were analyzed. For that matter a double hurdle model of probability and intensity of fertilizer adoption was estimated. Significant variables like Labor, education, livestock, quality of plot (lemteuf); and plots, distance from near town affect probability and intensity of adoption of inorganic fertilizer positively; and negatively respectively. Additionally, it was found that Age, household size, extension, credit and improved Varity; and chemicals, distance from plots, compost, plot, quantity of seed sown affect probability of adoption positively; and negatively respectively. In contrast, plot area, chemicals and quantity of seed sown affects intensity of fertilizer significantly and positively. Possible policy interventions on fertilizer prices, belief of high fertilizer application burns crops, complementary inputs to fertilizer i.e. Irrigation, compost and improve varieties is required.
