“…An example is the results of field experiments conducted in the Volgograd region, Tatarstan, Western and Eastern Siberia, and the Far East, where phosphorous flour was prepared from local phosphorous raw materials. Now, local agricultural ores are the most reliable source of improving the nutrient regime of soils and increasing the yield of agricultural crops [65]. Phosphorous flour from local deposits is the main source of phosphorus nutrition for agricultural crops and a means of reproducing soil fertility in the Russian Federation.…”

Considerable attention of the world community is now focused on the implementation of measures in the interests of achieving the global food security for future generations. Particular aspects of this problem include efforts aimed at increasing crop yields through the use of fertilizers. The purpose of this review is to analyze the experience of using organic and mineral fertilizers to increase crop yields in the cryolithozone of the European part of Russia for food security purposes. The fertility restoration methods of various Retisols considered in the review are of primary importance for the agriculture in the forest zone where 91% of arable lands are represented by this soil type. As these soils are low-fertility, poorly humified and acidic, they largely require the use of chemization and biologization means which are therefore an important factor in ensuring food security under the conditions of modern challenges.

Background. This study was dedicated to the evaluation and selection of maize hybrids of different origin for important agronomic traits and for protein and oil accumulation in grain under the conditions of Primorsky Territory, as well as for their possible use as source material for breeding.Materials and methods. Twenty-two grain maize hybrids of various geographic origin were studied at the Federal Scientific Center of Agricultural Biotechnology of the Far East named after A.K. Chaika” in 2017–2020. Useful agronomic characters and biochemical indications were assessed, correlations between parameters were established, and an integrated evaluation of maize hybrids was made. The hybrids were ranked relative to a predetermined ideal model.Results. Based on the results of the integrated assessment, maize hybrids Р 7709, Р 8688 and Р 8523 (Pioneer Corporation) and Si Rotango (Syngenta) had the highest scores for a set of important agronomic traits under the conditions of Primorsky Territory. Higher protein content levels were detected in maize grain when the combination of temperature and moisture was optimal (Selyaninov’s hydrothermal coefficient = 1.1). The highest oil content was observed at an enhanced level of soil moisture (HTC = 3.1). The Si Rotango hybrid had the maximum protein content. The NUR, Ladozhsky 181 MV and P 7054 hybrids showed the maximum in oil content. Strong direct correlations were discovered between the yield and the weight of 1000 kernels and one ear, and between grain yield and the height of the lower ear position. Weak reverse correlations were observed between biochemical parameters and yield, and between a FAO maturity group and grain yield.

The paper evaluates new promising soybean varieties and their parental forms with high yield, seed quality, and resistance to diseases and the stress conditions of Primorsky kray for a number of traits. The soybean accessions were used in a breeding program for constructing genotypes. Based on the research results, we selected promising soybean varieties characterized by a high yield and a high content of protein and oil in seeds. The yield of varieties Primorskaya 1670 and Primorskaya 1672 exceeded the standard by more than 32.2%. Varieties Primorskaya 1551 and Primorskaya 1674 had a high oil content in seeds – 23.8% and 24.1%, respectively. Variety Primorskaya 1659 was characterized by a high content of protein (41.2%). The parental forms used in the breeding of the new varieties were evaluated for a number of economically important traits. The yield of the starting forms ranged from 0.149 to 0.405 kg/m2. It was determined that 69.5% of the soybean accessions belonged to the group with mid-season maturity. A high content of protein in seeds (> 40.0 %) was detected in varieties of various origin – Primorskaya 13, Hefeng 25, NIISKH 2, XN 4, Arisa, and Kioto; variety NIISKH had a high oil content (24.2%). Varieties NIISKH 6, D 402-HH51, Arisa, NIISKH 5, XN 8, and XN 4 demonstrated a high potential adaptability to stress conditions.
