\textbf{Abstract}
\begin{abstract}
\normalsize{
Post"=independence period in Tajikistan witnessed promulgation of several decrees in a bid to transforming agriculture. Studies that critically examine the factors behind the very skimpy performance of this sector are simply scanty. The departure of this study from previous ones is that it considers the marked difference in farm size of the various crop production activities in the study area. Accordingly, the study uses DEA variables return to scale (VRS), which hitherto was not applied in this particular area. In so doing, this study contributes to the existing literature and brings a nuanced understanding of the major determining factors as far as technical efficiency of crop production is concerned. The fact that this study is confined to technical efficiency analysis is attributed to the issue of lucidity and manageability given the problems associated with data availability with regard to prices of inputs, which are essential in allocative efficiency analysis. 



This study is part of the ongoing CLINCA project with the major objective of analysing and developing agricultural production scenarios in Central Asia with response to climate change. Therefore, against the backdrop of the above"=mentioned issues, the objectives of this study are twofold: 1) gauging technical efficiency of farms and 2) identifying determinants of in/efficiency. The total sample constituted   303   randomly selected farm households from three districts of Soghd oblast(Northern part). Using two approaches vis-à-vis VRS input"=oriented approach in Data Envelopment Analysis and tobit model both at district and crop"=specific levels, the study has found out that farm indebtedness and delays in irrigation are more likely to negatively influence the efficiency level of farm households. Moreover, access to extension services plays an essential role. As a pointer for future endeavours, the needs of farm households and peculiarities of the districts and their comparative advantages should be considered.}
