      abstract = {The aim of this paper was to assess the joint productivity  of groups of agricultural holdings specializing
in field  cultivation, taking into account modifications being the  result of optimisation analysis and the DEA
method. The  results achieved by agricultural holdings operating in the  Pomerania and Masuria region in the
years 2004-2008 were  researched based on data collected by Polish FADN (Farm  Accountancy Data Network).
Productivity function was  measured using the three-factor Cobbs-Douglas production  function, whereas
changes in productivity were analysed  using mathematical optimisation models, that is Lagrange’s  method
of undetermined multipliers, linear programming  method and DEA non-parameter method. The results  were
compared with respect to farms’ productivity. The  analysis indicates that the highest increase in  productivity
was achieved after implementation of changes  suggested by Lagrange’s method of undetermined  multipliers.},
