Applying mineral and organic fertilizers under sugar beet is one among important measures of raisingthe level of economic efficiency of grain and beetroot crop rotations. However, there are not enough experimentaldata concerning the effect of fertilization system of sugar beet and other crops cultivated in the zoneof insufficient moistening on economic efficiency of short-term rotation crop succession. So, these are thetopicality and practical importance of corresponding studies, the aim of which is to determine the effect offertilizing sugar beet and other crops on economic efficiency of short-term rotation crop succession. The taskof the research was to study the influence of various fertilization systems used during cultivating sugar beetand other crops in short-term rotation crop succession, on different economic indicators, characterizing theefficiency of agricultural production; to choose the best variant of fertilizing sugar beet and other crops concerningeconomic characteristics. Corresponding experiments were conducted in the Left-Bank Forest-Steppe of Ukraine, during long-term permanent experiment in the structural subdivision of the Institute ofBio-Energy Crops and Sugar Beet of the National Academy of Agrarian Sciences of Ukraine, at VeselyiPodil Experimental Selection Station (in Semenivka district, Poltava region) during 2015–2018. As a resultof the studies, it has been established that in short-rotation crop succession, applying 6.25 t of manure +N56.2Р75.0К56.2 and 12.5 t of manure + N33.8Р45.0К33.8 per 1 ha of plow land during crop rotation resulted in thehighest gross output value – 19,166 and 19,270 UAH, respectively. Applying 6.25 t of manure +N11.2Р15.0К11.2 and 6.25 t of manure + N33.8Р45.0К33.8 during crop rotation ensured obtaining the highest netoperating profit per 1 ha of crop rotation area – 9,728 and 8,569 UAH, respectively. Among various fertilizers’doses, the best profitability was achieved at applying 6.25 t of manure + N11.2Р15.0К11.2 and 6.25 t of manure+ N33.8Р45.0К33.8 – 108 and 82 %, respectively, per 1 ha of rotation area during crop succession.
