aims study evaluate sustainability efficiency tomato production investigate determinants inefficiency tomato farming marand region east azerbaijan province iran purposes twostage methodology applied first time fractional regression model frm employed second stage analysis first stage nonparametric data envelopment analysis dea used analyze efficiencies tomato production second stage farm specific variables education level farmers age total land size use manure used fractional regression model explain factors influenced efficiency tomato farming results first stage showed considerable differences efficient inefficient farmers studied area main differences use chemical fertilizers biocides water irrigation also results second stage revealed farmers age education level total land size positively affected efficiency tomato production better use land chemical fertilizers water irrigation improving farmers educational levels literacy campaign land consolidation would probably increase efficiency long term
