Nowadays, table grape consumers prefer seedless grape varieties, so the market promotion of seedless varieties continues at a rapid pace. Responding to consumer preferences, the breeders have developed numerous various-flavour seedless varieties with large berries and bunches. The study purpose is to assess the prospects of cultivation and use in breeding of a new seedless Regal Seedless grape variety bred in South Africa. By origin, this is an intraspecific hybrid of the species V. vinifera L., with an early middle ripening period.

Analyzing the varieties of apple trees included in the assortment of the Orenburg region from various regions of our country, it can be noted that fruits of attractive appearance, large size, good taste and high yield are in the greatest demand. To achieve this goal, it is necessary to select varieties and introduce them as sustainable agrocenoses for the Orenburg region. The article presents the results of a study of 15 introduced apple varieties. Landing pattern is 3.0 × 5.0 m. The studies were carried out in 2019–2021.

A stationary field experiment carried out in 1978 on sod-podzolic heavy loamy soil (Eutric Albic Retisols (Abruptic, Loamic, Cutanic)) found that the application of mineral fertilizers in increasing doses led to acidification of the soil by the end of the fifth crop rotation in the arable layer with pH 5.6 when laying the experiment to pH 4.5 in the (NPK) 150 variant. The use of NPK at 90-150 kg ai/ha contributed to the preservation of the initial humus level, an increase in the content of mobile phosphorus to 452 and exchangeable potassium to 403 mg/kg.

Assessment of economically useful characteristics of maral fawns of the Novotalitskaya line of the Altai-Sayan breed

Increasing the profitability in the maral breeding industry primarily depends on the rational and focused rearing of young animals. The development of marals at an early age largely determines the additional economic value of these animals. The study’s objective is to assess the productive qualities of maral fawns of the Novotalitskaya line of the Altay-Sayan breed.

The review summarizes the results of domestic and foreign literature on the biological and ecological characteristics and use of orchardgrass in forage production. In Russia and the world, the orchardgrass is one of the most widespread species in natural and seeded meadows. With a sufficient supply of nitrogen, it surpasses other grasses in terms of competitiveness and yield, producing 5 to 12 t/ha of dry matter in different regions of Russia. Under optimal conditions of use, its productive longevity is 8 to 10 years or more.
