Аннотация: An optical remote assay for biological production of crops in the field during the vegetation period is proposed. Our calculations demonstrate a good correlation between the S(t) value and crop yield (in the range from 0.85 to 0.90); the higher is S(t) for the vegetation period, the higher is the crop yield. S(t) value can be used to calculate the increase in dry and wet biomass for various crops during the whole vegetation period with an error of less than 10-12%. The absolute error of crop yield for 110 cultivars of wheat, oats, and barley during the experimental period was +/-3-3.5 quintal/ha with the mean crop yield of 14-38 quintal/ha.

crops -- optical remote sensing techniques -- polarization characteristics
Аннотация: This paper presents an analysis of the study of the polarized component of the reflectance factor (Rq) and the degree of polarization (P) of wheat and maize crops depending on the wavelength. The polarization characteristics were obtained in the field from an elevated work platform at heights of 10 to 18 m in June and July. Measurements were performed using a double-beam spectrophotometer with a polarized light filter attachment within the spectral range from 400 to 820 nm. The viewing angle was no greater than 20° with respect to the nadir. The reflection spectra of wheat and maize crops that were obtained using a polarizer adjusted to transmit the maximum and minimum amounts of light (Rmax and Rmin) were studied. Based on these reflection spectra, the polarization characteristics, which differ in the visible and infrared spectral regions, were determined and analyzed. © 2015, Pleiades Publishing, Inc.

Estimation of chlorophyll content and yield of wheat crops from reflectance spectra obtained by ground-based remote measurements / A. F. Sid'ko [et al.] // Field Crops Res. - 2017. - Vol. 207. - P24-29, DOI 10.1016/j.fcr.2016.10.023 . - ISSN 0378-4290

Chlorophyll potential -- Optical remote method -- Wheat -- Triticum aestivum
Аннотация: This study aimed to analyze the relationship between chlorophyll potential, chlorophyll content, and grain yield of different wheat cultivars by using ground remote sensing and laboratory data. Chlorophyll potential is the difference between the reflectance factor integrals with and without chlorophyll absorption (in the 550–730 nm wavelength range). Ground-truth data were obtained at the experimental fields located in the Krasnoyarsk region, Russia (2002–2012). Experiments were conducted in different seasons under various lighting conditions by controlling plants states and soil types. Spectral measurements were obtained using a double-beam spectroradiometer, which was installed on a mobile work platform at a height of 5–18 m. The photometric area varied from 0.5 to 2 m2. The study showed good correlation (R2 = 0.9) between chlorophyll potential and chlorophyll content for different wheat cultivars. However, the correlation between chlorophyll potential and grain yield was less (R2 = 0.8). The values of chlorophyll potentials depended on the type of wheat during the growing season. The novelty of the approach is that it calculates the chlorophyll potential with additional spectral regions when compared with normalized difference vegetation index. We used a spectroradiometer with high spectral resolution. This increased the accuracy and stability of measurements in rapidly changing conditions. © 2016

SYSTEM
Аннотация: To increase the degree of closure of biological life support systems of a new generation, we used vermicomposting to involve inedible phytomass in the intra-system mass exchange. The resulting product was a soil-like substrate, which was quite suitable for growing plants (Manukovsky et al. 1996, 1997). However, the soil-like substrate can be regarded as a candidate for inclusion in a system only after a comprehensive examination of its physical, chemical, and other characteristics. An important criterion is the ability of the soil-like substrate to supply the necessary mineral elements to the photosynthesizing component under the chosen cultivation conditions. Thus, the purpose of this work was to study the feasibility of enhancing the production activity of wheat and radish crops by varying the intensity of photosynthetically active radiation, without decreasing the harvest index. The increase of light intensity from 920 to 1150 mumol(.)m(-2.)s(-1) decreased the intensity of apparent photosynthesis of the wheat crops and slightly increased the apparent photosynthesis of the radish crops The maximum total and grain productivity (kg/m(2)) of the wheat crops was attained at the irradiance of 920 mumol(.)m(-2.)s(-1). Light intensity of 1150 mumol(.)m(2.)s(-1) decreased the productivity of wheat plants and had no significant effect on the productivity of the radish crops (kg/m(2)) as compared to 920 mumol(.)m(-2.)s(-2). The qualitative and quantitative composition of microflora of the watering solution and substrate was determined by the condition of plants, developmental phase and light intensity. By the end of wheat growth under 1150 mumol(.)m(-2.)s(-1) the numbers of bacteria of the coliform family and phytopathogenic bacteria in the watering solution and substrate were an order of magnitude larger than under other illumination conditions. The obtained data suggest that the cultivation of plants in a life support system on soil-like substrate from composts has a number of advantages over the cultivation on neutral substrates, which require continual replenishment of the plant nutrient solution from the system's store to complement the macro- and micro- elements. Yet, a number of problems arise, including those related to the controlling of the production activity of the plants by the intensity of photosynthetically active radiation. It is essential to understand why the intensity of production processes is limited at higher irradiation levels and to overcome the factors responsible for this, so that the soil-like substrate could have an even better chance in the competition for the best plant cultivation technology to be used in biological life support systems.

Аннотация: The paper analyses the results of multi-year studies of the state of agricultural crops based on plant reflectance during the growth period. A universal methodology for determining the physiological state, and plant phytopigment content from the value of the chlorophyll potential S(t) in the region of the red absorption band lambda = 680 nm, which can be determined from the SEC values, is presented. It is shown that addition of mineral fertilisers (and, in particular, nitrogen) to soils, in on average 10 days slows the process of chlorophyll breakdown in phytocoenoses in comparison with control areas.

Аннотация: The paper presents results and analysis of a study on polarized characteristics of the reflectance factor of different plant canopies under field conditions, using optical remote sensing techniques. Polarization characteristics were recorded from the elevated work platform at heights of 10-18 m in June and July. Measurements were performed using a double-beam spectrophotometer with a polarized light filter attachment, within the spectral range from 400 to 820 nm. The viewing zenith angle was below 20 degree. Birch (Betila pubescens), pine (Pinus sylvestris L.), wheat (Triticum acstivum) [L.] crops, corn (Zea mays L ssp. mays) crops, and various grass canopies were used in this study. The following polarization characteristics were studied: the reflectance factor of the canopy with the polarizer adjusted to transmit the maximum and minimum amounts of light (R-max and R-min), polarized component of the reflectance factor (R-q), and the degree of polarization (P). Wheat, corn, and grass canopies have higher R-max and R-min values than forest plants. The R-q and P values are higher for the birch than for the pine within the wavelength range between 430 and 740 nm. The study shows that polarization characteristics of plant canopies may be used as an effective means of decoding remote sensing data. (C) 2014 Elsevier Ltd. All rights reserved.

Аннотация: The patterns of the phase portraits of vegetation (agrophytocenosis, woody vegetation) constructed using two-dimensional space radiation temperature values and Normalized Difference Vegetation Index were studied. An analysis of the phenological variability of vegetation in the south of the Krasnoyarsk Territory and the Republic of Khakassia during the growing seasons of 2003 and 2006 was carried out. Distinctive features of the phase portraits of agrophytocenosis and woody vegetation were revealed. The possibility of determining the boundaries of phenological states in the phytocenosis, and the transition range from one state into another was shown. Based on the complex analysis of the reflexive and radiative properties of the plant samples, an algorithm for calculating the start and end of the growing season was developed. © 2017, Pleiades Publishing, Inc.

Аннотация: Pesticides are commonly used in agriculture to enhance crop production and control pests. Therefore, pesticide residues can persist in the environment and agricultural crops. Although modern formulations are relatively safe to non-target species, numerous theoretical and experimental data demonstrate that pesticide residues can produce long-term negative effects on the health of humans and animals and stability of ecosystems. Of particular interest are molecular mechanisms that mediate the start of a cascade of adverse effects. This is a review of the latest literature data on the effects and consequences of contamination of agricultural crops by pesticide residues.

Аннотация: This paper presents the results of a study assessing the degree of weed infestation of wheat crops. They are obtained using optical ground-based and satellite spectral data with a 3-m spatial resolution from PlanetScope Dove satellites for 2019. The vegetation indices, including the normalized difference vegetation index (NDVI), the relative chlorophyll index (Chlorophyll Index Green-ClGreen or GCI), the modified soil-adjusted vegetation index (MSAVI2), and the visible atmospherically resistant index (VARI) are used in the interpretation of ground-based spectrometric and space images. This paper indicates the possibility of assessing the degree of weed infestation of agricultural fields. The higher the weed infestation, the lower the index values. The dynamics of VARI is found to be different from the dynamics of NDVI, ClGreen, and MSAVI2 during the growing season. The strong correlation between NDVI, ClGreen, and MSAVI2 and the weak correlation between VARI and other indices are observed. The possibility of identifying weedy sites in the agricultural fields is shown using the spatial distribution map of ClGreen dated August 2, 2019.

Amino acids in prospective feeds for fish aquaculture: A review of experimental data / V. I. Kolmakov, A. A. Kolmakova // J. Sib. Fed. Univ. - Biol. - 2020. - Vol. 13, Is. 4. - С. 424-442, DOI 10.17516/1997-1389-0332 . - ISSN 1997-1389

Аннотация: Total dependence of aquaculture on imports of feeds can significantly compromise Russia's food supply security; hence the task of designing new domestic feeds is of primary importance. A major challenge of world aquaculture is providing fish with a balanced diet, in particular, with a well-balanced composition of amino acids. In this review, we analyze international publications on the composition of amino acids in fish feed over the last two years. We summarize the data on the amino acid composition of prospective food sources for fish aquaculture: agricultural crops, insects, annelids, higher crustaceans, animal waste, phytoplankton, zooplankton, macrophytes, and microorganisms. We performed a comparative analysis of the composition of amino acids in promising aquafeed sources and fish flour traditionally used for fish feeding. Based on the results, we conclude that each of the examined food sources can be used as a component of fish nutrition and offers realistic prospects for production of alternative feeds. To ensure high quality of fish aquaculture products, the priority should be given to development of technologies which allow to control amino acid feed composition during the production process with respect to fish species-specific needs. It is hoped that this review will be useful to researchers and practitioners involved in designing and producing new domestic aquafeed for fish. © Siberian Federal University. All rights reserved.

Аннотация: The purpose of the present study was to investigate the efficacy of the experimental formulations of the metribuzin (MET) and tribenuron-methyl (TBM) herbicides embedded in the matrix of degradable poly-3-hydroxybutyrate blended with wood flour in field-grown tomato and beet crops infested by weeds. There is a necessity to develop environmentally friendly and effective means to protect plants because of the shortcomings of the free herbicide forms such as the environmentally unsafe spray application of solutions and suspensions of the widespread metribuzin and tribenuron-methyl herbicides, removal from soil during watering events and rains, and transport to natural aquatic environments, where the herbicides accumulate in the trophic chains of biota. Free TBM is also rapidly inactivated in soil and metabolized to nontoxic products in plants. The efficacy of experimental formulations of metribuzin and tribenuron-methyl embedded in the matrix of degradable poly-3-hydroxybutyrate blended with wood flour was tested in field-grown tomato and beet crops infested with weeds. Application of metribuzin resulted in the highest productivity of tomatoes (2.3 kg/m(2)) and table beet (3.4 kg/m(2)), improved biometric parameters of tomato fruits and beet roots, and caused reduction in nitrate nitrogen concentrations in them. The mode of herbicide delivery did not affect sugar contents, but application of both metribuzin and tribenuron-methyl induced a 1.7-fold and 1.4-fold, respectively, increase in vitamin C concentrations in tomato fruits and beet roots relative to the vegetables grown on the subplots treated with free herbicides and the intact plants. Embedded herbicides can be used as preemergence herbicides in the field.

Efficacy of Slow-Release Formulations of Metribuzin and Tribenuron Methyl Herbicides for Controlling Weeds of Various Species in Wheat and Barley Stands / T. Volova, A. Shumilova, N. Zhila [et al.] // ACS Omega. - 2020, DOI 10.1021/acsomega.0c02492 . - Article in press. - ISSN 2470-1343
Аннотация: The herbicidal activity of long-acting formulations of metribuzin and tribenuron methyl herbicides embedded in granules prepared from a mixture of degradable poly(3-hydroxybutyrate) and birch wood flour was studied in laboratory-grown weeds of various species and in wheat Triticum aestivum and barley Hordeum vulgare stands infested by weeds. The constructed formulations effectively suppressed all species of weeds studied. The biological effectiveness of herbicide formulations toward intact plants in wheat and barley stands infested with weeds was close to 100%, which was significantly higher than the effect of their free forms. The more effective suppression of weeds by embedded herbicides was beneficial for the growth of crops whose aboveground biomass was 8-13 to 20% greater than that of the crops in the treatments with free herbicides. Embedded metribuzin and tribenuron methyl exhibit sustained and pronounced herbicidal activity and are effective for pre-emergence soil application for crops infested with weeds of various species. © Copyright © 2020 American Chemical Society.

SYNTHASE-INHIBITING HERBICIDES
Аннотация: The herbicidal activity of long-acting formulations of metribuzin and tribenuron methyl herbicides embedded in granules prepared from a mixture of degradable poly(3-hydroxybutyrate) and birch wood flour was studied in laboratory-grown weeds of various species and in wheat Triticum aestivum and barley Hordeum vulgare stands infested by weeds. The constructed formulations effectively suppressed all species of weeds studied. The biological effectiveness of herbicide formulations toward intact plants in wheat and barley stands infested with weeds was close to 100%, which was significantly higher than the effect of their free forms. The more effective suppression of weeds by embedded herbicides was beneficial for the growth of crops whose aboveground biomass was 8-13 to 20% greater than that of the crops in the treatments with free herbicides. Embedded metribuzin and tribenuron methyl exhibit sustained and pronounced herbicidal activity and are effective for pre-emergence soil application for crops infested with weeds of various species.

Аннотация: The purpose of this work was to study the full-scale potential use of human mineralized waste (feces and urine) as a source of mineral elements for plant cultivation in a biological life support system (BLSS). Plants that are potential candidates for a photosynthesizing link were grown on a neutral solution containing human mineralized waste. Spring wheat Triticum aestivum L., peas Pisum sativum L. Ambrosia cultivar and leaf lettuce Lactuca sativa L., Vitaminny variety, were used. The plants were grown hydroponically on expanded clay aggregates in a vegetation chamber in constant environmental conditions. During plant growth, a determined amount of human mineralized waste was added daily to the nutrient solution. The nutrient solution remained unchanged throughout the vegetation period. Estimated plant requirements for macro-elements were based on a total biological productivity of 0.04 kg day-1 m-2. As the plant requirements for potassium exceeded the potassium content of human waste, a water extract of wheat straw containing the required amount of potassium was added to the nutrient solution. The Knop's solution was used in the control experiments. The experimental and control plants showed no significant differences in state or productivity of their photosynthetic apparatus. A small decrease in total productivity of the experimental plants was observed, which might result in some reduction of O{cyrillic}2 production in a BLSS. В© 2009 COSPAR.

A study of spectral-polarization characteristics of plant canopies using land-based remote sensing / A. F. Sid'ko [et al.] // Journal of Quantitative Spectroscopy and Radiative Transfer. - 2013. - Vol. 129. - P109-117, DOI 10.1016/j.jqsrt.2013.06.001 . - ISSN 0022-4073

Аннотация: The study addresses reflection and spectral-polarization characteristics of forest stands and farm crops obtained under field conditions. The study of the reflection properties of farm crops shows that during the summer plant growing season, the major factors influencing the plant canopy reflectance are morpho-physiological parameters, plant architectonics, solar elevation h0, and viewing angle. The crop reflectance minimum was recorded at viewing angles 25-30В° with respect to the nadir. Coniferous and broadleaf forest stands had similar reflectance spectra of polarized light. The polarized component was smaller for all coniferous stands than for broadleaf ones. For broad-leaved farm crops (wheat and corn), the polarized component of the spectral brightness coefficients had a greater influence on the plant reflectance in the red and near-infrared spectral regions, ?>720nm.

Аннотация: The work presents the results of the study aimed at determining the seasonal dynamics of the spectral brightness and reflectance of agricultural crops (wheat, barley and oats) in the Krasnoyarskii Krai (Russia). The analysis of spectral curves obtained through field ground measurements and from satellite data showed that fine spectral differences can be used to study the spatial distribution of various types of vegetation and their ecological state. Based on the created electronic spectral brightness data base, the possibilities are shown of using spectrophotometric information for determining morphophysiological changes occurring in the plants and their species composition. The determined contrasts can be effectively used to obtain necessary information while processing space images, which suffer from natural interferences (varying optical thickness of the atmosphere, cloudiness, alterations in the scanner's angle of view, varying solar height, and highly inhomogeneous underlying surface).
