The technology of creating varieties of barley resistant to the smut diseases has been developed. Their cultivation will help to reduce crop losses, increase the profitability of seed production, improve the quality of seeds, and reduce the environmental risk from the use of chemical plant protection products. This technology was first implemented in the Kemerovo Region in 1988-1999. The wide distribution of species Ustilago nuda (Jens.) Kell. et Sw. (65 %) and U. nigra Tapke (35 %) was revealed. The covered smut ( Ustilago hordei (Pers.) Kell. Et Sw.) was registered in individual collection varieties. The first and tenth races of a loose smut and the sixth race of a black loose smut were identified. The sources of individual and group immunity to the smut fungi from the world gene pool of barley are distinguished: Moskovsky 3/125, Suzdalets, Ramos (Moscow Region); Kazer (Rostov Region); line 3 KM-1192 (Belarus); Kumir Odessky (Ukraine); Guardian (Canada). The donor properties of resistance to a loose smut in the Bagan variety, line 53 HVS 91/76, line 1899 were studied. They are recommended for use in breeding programs. With their participation a new hybrid fund was created. Variability and inheritance of quantitative traits of productivity of hybrids was studied. To select the recombinants immune to the loose smut in combination with high productivity, the most promising combinations of hybrids have been identified: Bagan × Viner; Bagan × KM-16; l. 53 HVS 91/76 × KM-7; KM-7 × l. 1899; l. 1899 × KM-7. Among them, prospective breeding lines have been selected. The results of the implementation of technology elements in the selection of barley for resistance to smut fungi is the creation of immune highly productive varieties of a new generation: Simon and Luka (Kemerovo Region). They are included in the State register of breeding achievements since 2004.

Abstact. Varieties of spring ginger included in the State Register of breeding achievements and recommended for the Central Chernozem region, cultivated in the conditions of the forest-steppe of the Lipetsk region, form different yields of oilseeds in specific production conditions. The purpose of the research was to identify the most adaptive high-yielding varieties of spring ginger, suitable for cultivation in the forest-steppe conditions of the Central Chernozem region and providing high productivity. Research methods. When studying varieties according to the main economic characteristics, the method of competitive variety testing was used in accordance with the requirements of the state testing methodology and the field experience methodology of B. A. Dospekhov. Results. Spring ginger is a precocious crop with a growing season in the context of the studied varieties: Omich – 84 days, Ekaterininskiy – 79 days and Yubilyar – 75 days. The height of the varieties ranged from 59.3 to 67.8 cm. The Omich variety was short, and the Jubilee variety was the tallest. The maximum number of pods was observed in the Ekaterininskiy variety – 49.5 pieces per plant. Among the studied varieties of spring ginger, according to the complex of positive signs, the Ekaterininskiy variety stood out, which has a higher yield (1.52 t/ha without fertilizers and 1.88 t/ha against the background of N90P60K90), and the highest oil productivity (684 kg/ha without fertilizer and 833 kg/ha against the background of N90P60K90). The Omich variety had a high oil content of seeds (48%), but it was inferior to other varieties in terms of oil collection. The Yubilyar variety provided the highest yield of crude protein from 1 ha. Scientific novelty. For the first time on leached chernozem in the conditions of a typical forest-steppe of the Central Chernozem region, a comparative study of new-generation spring ginger varieties by a complex of economically useful characteristics was carried out and the genotypes most adapted for this region were determined.

The experience in cooperation of breeders of different institutions in creating cultivars is shown. It is not always when the breeding institution has the necessary initial forms for selection. In this regard, there is a need to conduct separate stages of selection in different breeding institutions. For this purpose, a provision on authorship and continuity in the integrated work of several institutions in fruit breeding has been developed (Program and methods of fruit, berry and nut crop breeding. Annex. – Orel, 1995. – pp. 492-498). Breeding work of the Russian Research Institute of Fruit Crop Breeding (VNIISPK) and North Caucasian Federal Scientific Center of Horticulture, Viticulture, Winemaking can serve as a positive experience of creating new apple cultivars by two institutions. As a result of the joint work of these two institutions, 22 apple cultivars have been created, of which 9 have already been included in the state register of breeding achievements approved for use (zoned), including three cultivars for the conditions of the Middle zone of Russia – Aleksandr Boiko, Maslovskoye and Yablochny Spas and six cultivars for the conditions of the North Caucasus – Vasilisa, Karmen, Margo, Orfey, Soyuz and Talisman. Brief economical and biological characteristics of these cultivars are given in this paper. The obtained practical results indicate that in some cases, when creating modern cultivars that meet the requirements of production, it is necessary to use the knowledge of breeders, the source material and equipment of different breeding institutions, and carry out separate stages of the selection process in different institutions.

Water shortage and drought are a growing problem in Europe. Therefore, effective methods for limiting its effects are necessary. At the same time, the “field to fork” strategy adopted by the European Commission aims to achieve a significant reduction in the use of plant protection products and fertilizers in the European Union. In an experiment conducted in 2018–2020, the effect of the method of foliar fertilization containing silicon and potassium on the yield and technological quality of sugar beet roots was assessed. The fertilizer was used in seven combinations, differing in the number and time of application. The best results were obtained by treating plants during drought stress. The better soil moisture for the plants, the smaller the pure sugar yield increase was observed. It is difficult to clearly state which combination of silicon and potassium foliar application is optimal, as their effects do not differ greatly.

AbstractThe pulse width modulation (PWM) spray system is the most advanced technology to obtain variable rate spray application without varying the operative sprayer parameters (e.g. spray pressure, nozzle size). According to the precision agriculture principles, PWM is the prime technology that allows to spray the required amount where needed without varying the droplet size spectra which benefits both the uniformity of spray quality and the spray drift reduction. However, some concerns related to the effect of on–off solenoid valves and the alternating on/off action of adjacent nozzles on final uneven spray coverage (SC) have arisen. Further evaluations of PWM systems used for spraying 3D crops under field conditions are welcomed. A tower-shaped airblast sprayer equipped with a PWM was tested in a vineyard. Twelve configurations, combining duty cycles (DC: 30, 50, 70, 100%) and forward speeds (FS: 4, 6, 8 km h−1), were tested. Two methodologies, namely field-standardized and real field conditions, were adopted to evaluate the effect of DC and FS on (1) SC variability (CV%) along both the sprayer travel direction and the vertical spray profile using long water sensitive papers (WSP), and (2) SC uniformity (IU, index value) within the canopy at different depths and heights, respectively. Furthermore, the SC (%) and deposit density (Nst, no stains cm−2), determined using short WSP, were used to evaluate the spray application performances taking into account the spray volumes applied. Under field-controlled conditions, the pulsing of the PWM system affects both the SC variability measured along the sprayer travel direction and along the vertical spray profile. In contrast, under real field conditions, the PWM system does not affect the uniformity of SC measured within the canopy. The relationship between SC and Nst allowed identification of the ranges of 200–250 and 300–370 l ha−1 as the most suitable spray volumes to be applied for insecticide and fungicide plant protection products, respectively.

Abstract In the central part of the European Union soybean, lupin and camelina are minor agricultural crops. The paper presents analysis of plant protection products availability for those crops in Austria, Belgium, Czech Republic, Germany, Holland, Hungary, Poland and Slovakia. Data from year 2019 show that availability of products is generally insufficient. For camelina in some countries, there are no chemical products available whatsoever. For lupin and soybean, there are not always products available to control some pest groups. However, the products on the market differ significantly among the member states. The results show that in protection of soybean, lupin and camelina, no single active substance is registered for the same crop in all the analysed member states. In very numerous cases, active substance is registered in one out of eight analysed member states only.
