    The paper covers the analysis of the development of the crop output market in Ukraine which ensures both food security of the country and the production of alternative fuel. The preconditions of negative changes in agriculture of Ukraine were studied. High profitability of corn and sunflower production encourages producers to increase their sown areas. The analysis of the production of some agricultural crops was made in the years of 2000–2019. The challenge of the use of nutritious residues of agricultural crops is discussed in the paper. The estimation of the production efficiency of some kinds of agricultural products at farm enterprises of Ukraine for the period of 2009–2019 was made. Some ecological-economical aspects of the use of nutritious residues of agricultural crops to balance mineral crop nutrition and to manufacture bio-fuel were suggested.

    Potential of renewable sources in Ukraine
    (Wydawnictwo SGGW, 2021) Rybchak, Vitalii; Doronin, Andrii; Polishchuk, Olena
    Bearing in mind a serious dependence of Ukraine on the import of oil products, it is of great significance for Ukraine to develop own manufacture and to increase the share of oil product substitution with biofuel. It is not possible to develop biofuel market without solving a number of economic and organizational problems, which is why it is expedient to introduce financial-economic stimuli for biofuel producers and to build a stable demand for alternative kinds of fuel. In Ukraine the manufacture of alternative fuels almost terminated, however the solution of the problem of biofuel manufacture will depend on the coordination of joint actions of the state, participants of market relations and the development of the system of measures aimed at the creation of pre-conditions to enhance a competitive biofuel market in Ukraine, taking into consideration foreign experience and current tendencies of the manufacture and use of the alternative energy sources.
