Table 11

Summary of partial economic analysis of teff production due to the effects of varieties and blended NPSZnB fertilizer rates application on-farm.


Variety	NPSZnB rate (kg ha⁻¹)	Adjusted grain yield (kg ha⁻¹)	Adjusted straw yield (kg ha⁻¹)	Total revenue (ETB ha⁻¹)	Total variable cost (ETB ha⁻¹)	Net benefit (ETB ha⁻¹)	Marginal rate of return (%)

Where D = dominated treatments. ETB ha⁻¹ = Ethiopian Birr per hectare; Market price of teff = 35 ETB kg⁻¹; Market price of straw = 0.5 ETB kg⁻¹; Cost of blended NPSZnB fertilizer = 750 birr per 50 kg, Labor cost for fertilizer application = 1 person for 50 kg, each at 70 ETB day⁻¹.
