In modern agriculture, the actual direction is the development of approaches to preservation and accumulation of available moisture in the soil, which is possible with a rational combination of measures of primary and preseeding tillage. The article presents the results of research on the influence of different variants of primary and preseeding tillage on the reserves of available moisture and the yield of the buckwheat in the conditions of the Carpathian region of Ukraine. The article presents the results of research on the influence of different variants of soil tillage on the reserves of available moisture and the yield of the buckwheat in the conditions of the Carpathian region of Ukraine. The research was conducted in the conditions of the Carpathian State Agricultural Research Station 120 of NAAS and the Laboratory of the Department of Agriculture and Herbology of NULES of Ukraine during 2015–2017. According to the results of two stationary experiments, it has been found that maintaining the available moisture in the soil is facilitated by the use of chisel plowing on 20-22 cm and the successive conducting of early spring harrowing, harrowing with heavy tooth-boring harrows (as weed germination) and pre-sowing cultivation to the depth of sowing. This allowed to accumulate 39.6 mm of moisture at a depth of 0–30 cm and 205.1 mm in a meter and yield the highest grain yield of buckwheat in the experiments at the level of 3.61 t/ha.
