“…Natural siliceous minerals present promise as environmentally friendly regulators of the biogeochemical nitrogen cycle. In contrast to synthetic nitrification inhibitors natural siliceous minerals do not impose any harm to soil microbiota and were shown to have beneficial effect on crop productivity [10,11]. They are stable in the soil environment, and, after having been applied once, express their effect for many years.…”

The comparative study on the effects of nitrapyrin and the mixture of natural siliceous minerals on physiological processes in economically important C3 and C4 crops (viz. wheat and corn) grown under high nitrogen fertilization conditions, as well as on soil microbiota and nitrogen balance, was conducted in the laboratory and long-term field experiments. The siliceous minerals were shown to have significantly higher inhibitory effects on the nitrification process in different types of soils, amended with urea, the number of nitrifiers and micromicetes producing phytotoxic allelochemicals compared with nitrapyrin. Crops treated with siliceous minerals had higher photosynthetic pigment content and higher glutamic acid concentration, which indicated the intensification of photosynthetic processes. Nitrapyrin reduced the concentration of chlorophyll b and carotenoids, but slightly increased the content of chlorophyll a in the leaves of wheat and corn. The content of aspartate and some aromatic amino acids decreased, while arginine and lysine increased. Such metabolic changes suggested disintegration of nitrogen and phosphate metabolism in the studied crops. Thus, the use of siliceous minerals is more advantageous than nitrapyrin in terms of their effectiveness, persistence in various types of soils and beneficial effect on soil microbiota and crops’ functional state and productivity.

Перспективи застосування кремнієвмісної органо-мінеральної суміші для зниження ґрунтовтоми в плодових садах Представлено членом-кореспондентом НАН України Н.В. Заіменко Досліджено вплив кремнієвмісної суміші на алелопатичні, мікробіологічні, фізико-хімічні властивості прикореневого ґрунту та життєвий стан плодових рослин за умов монокультури. Показано ефективність її застосування для зниження ґрунтовтоми в плодових садах, що обумовлено активізацією мікробіологіч них процесів, оптимізацією окисно-відновного, алелопатичного, поживного режиму та підвищенням стійкості рослин.

The research relevance is determined by the need to develop modern scientific and practical principles of involving little-known, rare, and newly created plant genotypes in the introduction process. This will help to warn of a possible phytoproduct crisis caused by climate change and rapid population growth on the planet. The research aims to determine the morphological characteristics and biochemical features of Cicer arietinum seeds for improving the germplasm of legumes and conducting further breeding and biotechnological research. The comparative morphological method was used for seeds of introduced plant genotypes from different regions of origin. The material for the study was 9 genotypes of Cicer arietinum originating from Australia, Afghanistan, Azerbaijan, and Ukraine, which were grown in experimental plots of the M.M. Gryshko National Botanical Garden. Morphometric parameters and some biochemical properties of plant seeds were studied depending on genotypic characteristics. Field, laboratory, and methods of analysis of variance and statistical evaluation of average data were used using Microsoft Excel (2010). In the course of the research, it was found that all introduced genotypes are characterised by high quantitative and qualitative indicators of seeds. In terms of linear seed dimensions (length to width ratio), the sample CAAFGK-1 was particularly distinguished – 17.12 × 14.38 mm, and in terms of weight of 1000 seeds CATADJK-1 – 584.5 g. Biochemical studies have shown that the highest amount of absolute dry matter was accumulated in the seeds of C. arietinum samples – CAAFGD-2, CAAFGK-1, CATADJD-2 and CATADJK-1 (from 89.04 to 89.68%). The level of total sugars was dominated by the samples of C. arietinum genotypes CATADJK-1 – 9.37%, and the accumulation of phosphorus was dominated by CAAZEUR-2 – 1.43%. The biochemical composition of plants makes it possible not only to characterise their value in terms of food crops but also to determine the most plastic genotypes to environmental factors. Thus, the results obtained indicate the prospects of using certain genotypes of C. arietinum as a starting material for breeding and biotechnological research and the creation of new plant forms, which will help to expand the range of highly productive chickpea genotypes in the northern regions of Ukraine
