Abstract. The aim of the research was to develop effective variants of cultivation technology for huskless oat at the application of calculated fertilizer doses with the use of top-dressing with humic and complex microelement fertilizers and nanosilver. In 2012–2014 the three-factor experiment was carried out in Tver region on well cultured sod-medium podzol sabulous soil. The experimental design included the following options: factor A was varieties (Vyatsky and Percheron); factor B was cultivation technologies (environmentally clean, environmentally safe, intensive); factor C was top-dressings (Agrohumate-Extra, Max-Super Humate, Aquadon-Micro, nanosilver AgBion-2). The control was without fertilization. The discount area of a plot was 36.7 m2; the replication was three-fold. The main fertilizer for environmentally clean technology was not used. Calculated doses of NPK for the yield of 3.0 t/ha (N60P0K55) and 4.0 t/ha (N90P0K90) were applied at ecologically safe and intensive technologies. The varieties slightly differed in growth, development and yield formation. On average over three years and the variants of spraying the yield of Vyatsky and Percheron varieties was 1.26 and 1.42 t/ha at the environmentally clean technology, 2.02 and 2.02 t/ha at the environmentally safe technology, and 2.59 and 2.57 t/ha at the intensive technology. Top-dressings with all fertilizers and nanosilver increase the yield. Higher yield increases were obtained in the case of treatment by Max-Super Humate (29.1–47.2%) at the environmentally clean technology and by nanosilver AdBion-2 at the environmentally safe and intensive technologies (27.4–43.9 and 36.2–35.8%, respectively). These variants provided the highest net income per hectare (from 9,150 to 19,190 rubles) with the level of profitability from 55.3 to 63.6%. In the years with favourable weather conditions both varieties formed the yield close to the programmed levels of 3.0 and 4.0 t/ha.
