In the conditions of sod-podzolic soils of the non-chernozem zone of Russia, the transition to
regenerative agriculture is urgent, in which siderates play an important role. In the field experiment
in 2024, on the sod-podzolic soil in the central zone of Kirov region, varieties of narrow-leaved lupine
(Accord, Flamingo, Oligarch, Fedorovsky, Metsenat) were studied according to the possibility of
their use as siderates. The yield of the green mass, the content and collection of nitrogen and fiber
were evaluated. It was found out that all varieties of lupine significantly exceed the control ones in
productivity (by 12.1-16.9 t/ha) and nitrogen collection (by 2.0-2.5 times). The maximum values of
the green mass yield (32.4 t/ha) and nitrogen collection (0.88 t/ha) were noted in the variety Accord,
and the maximum fiber collection (2.22 t/ha) was in the variety Flamingo. The high fiber content
indicates the structure-forming potential and a delayed release of nitrogen. The results confirm the
promising use of lupin in regenerative farming systems.

In the conditions of the existing protein feed shortage in the non-chernozem zone of the
Russian Federation, the cultivation of adapted leguminous crops on drained peat soils is a promising
direction. In 2023, a field experiment was conducted on the old-arable lowland peat soil of the drained
peat massif “Gadovsky” to cultivate the narrow-leaved lupine (Lupinus angustifolius L.) of the variety
Belozerny 110. Despite the abnormal weather conditions (cold and dry June, and excessive moisture
in July), the yield of green mass was 204.95 centners per hectare. This is 2.6 times higher than
the average Russian yield for annual grasses. The yield of crude protein reached 267 kilograms
per hectare. With a decrease in the content of crude protein (11.9 % in dry matter) and an increase
in fiber (34.5 %), the plants have a characteristic “carbohydrate” growth pattern. The energy
consumption per 1 ton of crude protein (8.8 GJ) is among the lowest, which confirms the high
competitiveness of this crop when grown on lowland peat soils.

In the conditions of a short growing season and low insolation in Kirov region (nonchernozem zone of the Russian Federation), tomato cultivation in protected soil requires the selection
of genotypes that combine early ripeness, yield and high fruit quality. In 2024, the comparative
assessment of four promising indeterminate heterotic F1 hybrids of the large-fruit group (VS 44-23 F1,
GN 54/19 F1, GN 6/21 F1, GN 45/20 F1) was carried out. These hybrids were grown in unheated
polycarbonate greenhouses. The hybrid F1 Coral Reef acted as a control one. It was found out that
the hybrid GN 54/19 F1 (group 1 of the early ripeness, 94 days) significantly exceeds the control one
in total yield (10.9 kg/m2
), has large fruits (156 g) and demonstrates high quality according
to organoleptic evaluation (4.7 points). This sample is the most adapted to local conditions.
The VS 44-23 F1 hybrid is distinguished by its maximum fruit weight (183 g) and sugar content
(4.5 Brix %). However, it shows the 35 % decrease in the yield. Its cultivation is advisable for
the premium segment with additional technology intensification. The results allow us to recommend
GN 54/19 F1 for widespread introduction into industrial greenhouse production in the region.

This article presents the experiment results on the effect of the drugs Eimeterm suspension
5 % and Tylosin 200 on the biochemical parameters of the blood of calves with spontaneous eimeria
invasion. According to the results of coproscopy, oocysts of Eimeria bovis, Eimeria ellipsoidalis and
Eimeria zuernii were found in the calves aged 2-2.5 months. The calvesinvasion extensity by E. bovis eimeria species was 100 %. The research results showed 100 % therapeutic efficiency of the studied drugs. In the biochemical analysis of the calves blood serum, after using Eimeterm
5 % and Tylosin 200, the globulin level in the experimental groups increased by 5.5 and 4.1 %, respectively. ALT and AST levels in the experimental groups increased by 2 and 1.5 times,
respectively, and significantly exceeded the values in the control group. No negative changes were
observed in the analysis of carbohydrate and general mineral metabolism. The studied drugs did
not have a negative effect on the dynamics of the main indicators of protein, carbohydrate, and
mineral metabolism, but they did affect the increase in the liver enzymes activity.
