Vasylieva, N. and A. Pugach, 2017. Economic assessment of technical maintenance in grain production of Ukrainian agriculture. Bulg. J. Agric. Sci., 23 (2): 198–203
This paper explores the ways of increasing Ukrainian contribution to the grain segment of the world food security system. Statistics confi rmed that three main exported crops are wheat, barley and maize, which have signifi cantly unstable yields and profi tability in Ukraine. The performed econometric analyses have verifi ed a reverse dependence of grain losses on scales of sown areas, which are restricted because of insuffi cient and outdated agricultural machinery. The conducted cluster modeling made possible to form regional groups of common development in grain production and defi ne achievable purchase quantities of tractors and harvester combines to enhance effectiveness in grain segment of Ukrainian agriculture.
