Abstract: Purpose. To determine the impact of various organic fertilisation systems on the yield of crops in a short-rotation crop rotation system and on the economic and energy efficiency of their cultivation in the subzone of variable moisture conditions of the Left-Bank Forest-Steppe. Methods. The study was conducted between 2023 and 2025 in the subzone of unstable moisture conditions of the Left-Bank Forest-Steppe of Ukraine, on typical low-humus chernozem at the Panfilov Research Station of the National Research Center “IA NAAS”, (Kyiv region). The following methods were used: field methods (determining the interaction of the study objects with natural and agronomic factors), laboratory (determination of the content of major nutrients in soil and plants), computational and comparative (assessment of the economic efficiency of growing agricultural crops in a short-rotation crop rotation under different organic fertilisation systems), statistical and mathematical (conducting analysis of variance) and statistical processing of the results obtained. Results. Results from a stationary field trial indicate that organic fertilisation systems significantly impact the yield and productivity of crops in a short-rotation organic crop rotation involving soya, spring wheat and buckwheat. The greatest effect was achieved by using a combination of by-products from the previous crop, green manure and biofertiliser. Using this fertilisation system resulted in yields of 1.84 t/ha for the ‘Muza’ soybean variety, 3.83 t/ha for the ‘Rannia’93 spring wheat variety and 1.70 t/ha for the ‘Syn 3/02’ buckwheat variety. These figures exceeded those of the control by 29%, 33% and 31%, respectively. The highest crop rotation productivity was also recorded with the integrated fertilisation system. The yield of forage units ranged from 2.54 to 4.68 t/ha, grain units from 2.38 to 3.83 t/ha and digestible protein units from 0.19 to 0.53 t/ha depending on the crop. An economic assessment showed an increase in notional net profit to 40.4 thousand UAH/ha, as well as a rise in the energy efficiency ratio to 3.42. Conclusions. The complex use of by-products of the predecessor crop used in crop rotation, green manure crops and biofertilizers is the most effective fertilization system for short-rotation organic crop rotation in conditions of unstable moisture in the Left-Bank Forest-Steppe. Such a system ensures an increase in crop yield, arable land productivity, economic and energy efficiency of production.
