Features of the microbial biological “Flavobacterin” impact on the yield and quality of potato tubers of the Udacha variety

Relevance. Organic production is focused on maximizing the use of natural resources. Particular importance is attached to natural nitrogen fixation. Nitrogen fixation provides agricultural systems with nitrogen fixed from the atmosphere and converted into forms accessible to plants. The microbial biological “Flavobacterin”, which exhibits nitrogen-fixing activity and also suppresses a wide range of phytopathogenic fungi and bacteria, was created at the All-Russian Institute of Agricultural Microbiology.Methods. Field studies of the “Flavobacterin” effects on potatoes were carried out from 2018 to 2022 in an organic crop rotation located at the Experimental Station of the Institute for Engineering and Environmental Problems in Agricultural Production Branch of FSAC VIM.Results. The soil of the experimental plot is soddy-podzolic, light loamy gleyic on residual carbonate moraine loam, characterized by a slightly acidic reaction and a high content of organic matter. Udacha variety potatoes were cultivated. The studies were carried out with organic fertilizer — BIAGUM compost, prepared from chicken manure by industrial method. Potato tubers were treated with a “Flavobacterin” when planting, and then on the leaves. Weather conditions in summer during the years of research differed significantly from each other. In all years of the study, with the exception of the dry year 2021, the application of “Flavobacterin” significantly increased potato productivity by an average of 4.4 t/ha, without compost. In the same years, the use of compost together with “Flavobacterin” increased potato productivity by an average of 2.6 t/ha compared to options where compost was used without biological.

Unraveling the Rich Fragmentation Dynamics Associated with S-H Bond Fission Following Photoexcitation of H2S at Wavelengths ∼129.1 nm.

H2S is being detected in the atmospheres of ever more interstellar bodies, and photolysis is an important mechanism by which it is processed. Here, we report H Rydberg atom time-of-flight measurements following the excitation of H2S molecules to selected rotational (JKaKc') levels of the 1B1 Rydberg state associated with the strong absorption feature at wavelengths of λ ∼ 129.1 nm. Analysis of the total kinetic energy release spectra derived from these data reveals that all levels predissociate to yield H atoms in conjunction with both SH(A) and SH(X) partners and that the primary SH(A)/SH(X) product branching ratio increases steeply with ⟨Jb2⟩, the square of the rotational angular momentum about the b-inertial axis in the excited state. These products arise via competing homogeneous (vibronic) and heterogeneous (Coriolis-induced) predissociation pathways that involve coupling to dissociative potential energy surfaces (PES(s)) of, respectively, 1A″ and 1A' symmetries. The present data also show H + SH(A) product formation when exciting the JKaKc' = 000 and 111 levels, for which ⟨Jb2⟩ = 0 and Coriolis coupling to the 1A' PES(s) is symmetry forbidden, implying the operation of another, hitherto unrecognized, route to forming H + SH(A) products following excitation of H2S at energies above ∼9 eV. These data can be expected to stimulate future ab initio molecular dynamic studies that test, refine, and define the currently inferred predissociation pathways available to photoexcited H2S molecules.

Study of excited Ξ states in ψ(3686)→K−ΛΞ¯++c.c.

Based on a sample of (448.1±2.9)×106 ψ(3686) events collected with the BESIII detector at BEPCII, the decays of ψ(3686)→K−ΛΞ¯++c.c. with Ξ¯+→Λ¯π+, Λ¯→p¯π+ are studied. We investigate the two excited resonances, Ξ(1690)− and Ξ(1820)−, which are each observed with large significance (≫10σ) in the K−Λ invariant mass distributions. A partial wave analysis is performed, and the spin-parities of Ξ(1690)− and Ξ(1820)− are measured to be 12− and 32−, respectively. The masses, widths, and product branching fractions of Ξ(1690)− and Ξ(1820)− are also measured. Published by the American Physical Society 2024

Why together? Archaeology and zoology about medieval leather products on the example of Szczecin

Abstract Many years of archaeological excavation brought to light a rich material, that can be used in research of topics important from a social and economic point of view, such as the character of the production and/or organization, the development of technique and production technology, or the assortment of goods. A deep analysis of the selected categories of artifacts, in this case made of leather, can be used for a double purpose – a reconstruction of the process and conditions of early medieval leather craft formation, as well as a presentation of their role and significance in the activity structure of the inhabitants of Szczecin. Such an attempt to grasp the rules governing the development of one of the most important production branches – leatherworking, has been undertaken on the basis of leather objects that can be found on a mass scale in Szczecin’s cultural layers dated for the period from the early 10th to the mid-13th century. Key to these studies are the results of zoological analyses, which perfectly complement the archaeological conclusions.

Management of marketing activities in agricultural enterprises producing white sea buckthorn

Marketing management in a practical sense means management that uses marketing concepts, i.e. the management of an enterprise that has adopted and uses the marketing view or philosophical vision of marketing in its development process. The management of marketing activity of the enterprise in which there is the branch of production of white currant there must be organizational structures through which each employee, with different functions, level of training and duties, has the opportunity and obligation to act on the basis of marketing strategies, as well as responsibility centers. The concept of actively influencing market requirements also implies effective management of specialized marketing activity, i.e. activities related to product, pricing, placement and promotion policies. In order to establish appropriate management of marketing activity and to position it as effectively as possible in the organizational chart of an agricultural enterprise in which there is a white currant production branch, it is specific, first of all, to analyses the background parts of the constituent elements of the environment with which it operates in order to be able to establish strategic lines, which need to correspond to the appropriate form of organization. In the given article, the authors intend to identify and propose solutions to some problems, which, in essence, represent a diagnostic analysis of the enterprise, the results of which indicate one of the options for the organization of marketing activity and marketing department or specialist in agricultural enterprises.

Ozonolysis of 2-Methyl-2-pentenal: New Insights from Master Equation Modeling.

Experimental and theoretical studies were carried out to investigate the ozonolysis of trans-2-methyl-2-pentenal. The experiments were conducted in atmospheric simulation chambers coupled to a Fourier transform infrared (FTIR) spectrometer and a gas chromatograph-mass spectrometer at room temperature and atmospheric pressure in the presence of an excess of cyclohexane in dry conditions (RH < 1%). The ozonolysis reaction was investigated theoretically from the results of accurate density functional (M06-2X) and ab initio [CCSD(T)] computations, employing the AVTZ basis set. The sequence of reaction steps was established, and the system of kinetics equations was modeled using MESMER. In the first step, a primary ozonide is formed, which then decomposes along two pathways. The principal ozonolysis products are propanal, methylglyoxal, ethylformate, and a secondary ozonide. An interesting competition between sequential reaction steps and well-skipping is found, which leads to an inversion of the expected methylglyoxal/propanal product ratio at temperatures below 210 K. The mechanism of the "hot ester" reaction channel of the Criegee intermediate was revisited. The computed ozonolysis rate constant and product branching ratio are in excellent agreement with the experimental data that are also reported in the present work.

Total pod weight was positively correlated with the number of productive branches (r = 0.83), the number of good pods (r = 0.96), and the total number of pods (r = 0.96). The number of productive branches correlated positively with the number of good pods (r = 0.87) and the total number of pods (r = 0.86). The number of good pods variable has a positive correlation with the total number of pods (r = 0.98). The Cantonese Tavi variety has an advantage in the number of good pods produced in an organic environment. Keywords: Correlation, Organic Environment.

Effects of Mycorrhizal on The Growth and Yield of Cayenne Pepper (Capsicum frutescens L.)

Innovations are required to increase the production of cayenne pepper (Capsicum frutescens L), mainly due to the need for more quality land, such as dry land in Wamena. The innovation uses biological microorganisms that positively impact plants, such as arbuscular mycorrhizal fungi (AMF). Therefore, this experiment aimed to determine the response of the growth and yield of cayenne pepper plants cultivated in dry land to the application of mycorrhiza. The research was conducted using a completely randomized design with one factor: the mycorrhizae dose (0, 20, 50, 80, and 120 g). The research results were analyzed using ANOVA, and the analysis process continued with the 5% level DMRT test. The research results on the growth of cayenne pepper are visible in the plant height parameters of the 80 g treatment (75 DAP: 93.4 cm) and the 120 g treatment (95 DAP: 103.3 cm). Then, the stem diameter parameter showed a real influence by the 120 g mycorrhiza treatment at 35 and 75 DAP and the 80 g mycorrhiza treatment at 95 DAP. The excellent response of plants to the 80 g and 120 g mycorrhiza treatments also impacted the plant's total chlorophyll content and the number of leaves produced, which then impacted the number of productive branches. So, the effect on the yield of cayenne pepper plants is that the number of fruits treated with 80 g of mycorrhiza was 89.7 fruits, with the weight of the heaviest cayenne pepper fruit being 68.0 g by the treatment of 120 g of mycorrhiza with a fresh weight of 17.6 g and a total dry plant of 10.2 g compared to the control.

Predicting pressure-dependent rate constants for the furan + OH reactions and their impact under tropospheric conditions.

In this work, we have evaluated the influence of temperature and pressure on the mechanism of furan oxidation by the OH radical. The stationary points on the potential energy surface were described at the M06-2X/aug-cc-pVTZ level of theory. In the kinetic treatment at the high-pressure limit (HPL), we have combined the multistructural canonical variational theory with multidimensional small-curvature tunneling corrections and long-range transition state theory. The system-specific quantum Rice-Ramsperger-Kassel theory was employed to estimate the pressure-dependent rate. In the HPL, the OH addition on the α carbon is the dominant pathway in the mechanism, producing a product via the ring-opening process, also confirmed by the product branching ratio calculations. The overall rate constant, obtained by a kinetic Monte Carlo simulation, reads the form koverall=5.22×10-13T/3001.10⁡exp1247(K/T) and indicates that the furan oxidation by OH radicals is a pressure-independent reaction under tropospheric conditions.

Yield performance and stability analysis of three cultivars of Gayo Arabica coffee across six different environments

Abstract The three cultivars of Gayo Arabica coffee (GAC) are distributed widely in the Gayo Highlands, Aceh Province, Indonesia, between 900 and 1,700 m above sea level (masl). The difference in altitude affects the yield and quality of coffee, and Arabica coffee has biennial bearing characteristics, so there are always annual yield fluctuations. This study aimed to determine the yield performance and stability level of the three GAC cultivars, Gayo 1, Gayo 2, and Gayo 3 (G3), across six different environments. The study used a randomized complete block design with three replications. The six environmental conditions are the combinations of two altitudes (900 and 1,500 masl) and 3 years of production (2019, 2020, and 2021). The estimation of coffee yields is based on the fruit value, which is calculated by the number of productive branches per tree, nodes per branch, berries per node, and the weight of a single cherry. An investigation of the genotype-by-environmental interaction using a combined analysis of variance and the yield performance and stability analysis performed using the Eberhart and Russell method, AMMI (additive main effects and multiplicative interaction) and GGE (genotype + genotype × environment) biplot analysis. Results showed that the yield performance of GAC was significantly affected by the interaction between genotype and environment. G3 was an ideal cultivar because it had high yield performance, was stable, and could adapt to broader environments in Gayo Highland. Therefore, G3 deserves high priority for Arabica coffee development in that region.

Updated measurements of the M1 transition ψ(3686)→γηc(2S) with ηc(2S)→KK¯π

Based on a data sample of (2712.4±14.3)×106ψ(3686) events collected with the BESIII detector at the BEPCII collider, the M1 transition ψ(3686)→γηc(2S) with ηc(2S)→KK¯π is studied, where KK¯π is K+K−π0 or KS0K±π∓. The mass and width of the ηc(2S) are measured to be (3637.8±0.8(stat)±0.2(syst)) MeV/c2 and (10.5±1.7(stat)±3.5(syst)) MeV, respectively. The product branching fraction B(ψ(3686)→γηc(2S))×B(ηc(2S)→KK¯π) is determined to be (0.97±0.06(stat)±0.09(syst))×10−5. Using B(ηc(2S)→KK¯π)=(1.86−0.49+0.68)%, we obtain the branching fraction of the radiative transition to be B(ψ(3686)→γηc(2S))=(5.2±0.3(stat)±0.5(syst)−1.4+1.9(extr))×10−4, where the third uncertainty is due to the quoted B(ηc(2S)→KK¯π).

Search for Scalar Leptoquarks Produced via τ-Lepton-Quark Scattering in pp Collisions at sqrt[s]=13 TeV.

The first search for scalar leptoquarks produced in τ-lepton-quark collisions is presented. It is based on a set of proton-proton collision data recorded with the CMS detector at the LHC at a center-of-mass energy of 13TeV corresponding to an integrated luminosity of 138 fb^{-1}. The reconstructed final state consists of a jet, significant missing transverse momentum, and a τ lepton reconstructed through its hadronic or leptonic decays. Limits are set on the product of the leptoquark production cross section and branching fraction and interpreted as exclusions in the plane of the leptoquark mass and the leptoquark-τ-quark coupling strength.

Effect of Poultry Manure and Ethephon on Growth, Yield, and Quality of Cayenne Pepper (Capsicum frutescens L.) ‘Ratuni UNPAD’

&lt;p&gt;&lt;span lang="IN"&gt;The production of 'Ratuni UNPAD' cayenne pepper can be increased using organic chicken manure. However, the application of ethephon is needed during fertilization due to the significantly slow flower initiation. Therefore, this study aim&lt;/span&gt;&lt;span&gt;s&lt;/span&gt;&lt;span&gt; &lt;span lang="IN"&gt;to determine the interaction between chicken manure and ethephon on the growth, yield, and quality of the 'Ratuni UNPAD' cayenne pepper. Planting &lt;/span&gt;&lt;/span&gt;&lt;span&gt;is &lt;/span&gt;&lt;span lang="IN"&gt;carried out 829 meters above sea level (masl), and a factorial randomized block experimental design comprises 2 factors with 3 replications. The first factor &lt;/span&gt;&lt;span&gt;i&lt;/span&gt;&lt;span lang="IN"&gt;s the dose of chicken manure (10, 20, 30, and 40 t/ha), while the second is the ethephon concentration (0, 500, 1000, and 1500 ppm). The results showed no interaction between poultry manure and ethephon on the growth, yield, and quality of the 'Ratuni UNPAD' cayenne pepper. According to the doses of chicken manure, 40 t/ha significantly affect&lt;/span&gt;&lt;span&gt;s&lt;/span&gt;&lt;span lang="IN"&gt; the flower initiation, fruit number, weight, length, and diameter, as well as capsaicin and dihydrocapsaicin. The 30 t/ha shows the highest value for the number of leaves and productive branches, while 20 tons dose/ha influences flavonoids, phenolics, and total carotenoids. The ethephon concentration of 1500 ppm significantly affects the flower initiation, fruit length, diameter, capsaicin, and dihydrocapsaicin.&lt;/span&gt;&lt;/p&gt;

Effect of eco-enzymes on vegetative and generative growth in several kipas putih soybean (Glycine max (L) Merr.) mutant lines

This research used soybeans resulting from gamma-ray radiation mutations of the Kipas Putih variety to obtain new superior varieties that are better than their parents. The research was carried out at the East Sector 2 Experimental Garden, as well as the Genetics and Plant Breeding Laboratory, Faculty of Agriculture, Syiah Kuala University from April to July 2023. This research used a Randomized Completely Block Design (RCBD) in a 2 x 4 factorial pattern with 3 replications so that there are 24 experimental units. The first factor is the concentration of ecoenzyme (K) which consists of 2 levels (without eco-enzyme and 10 ml L−1), while the second factor was the soybean line which consists of 4 levels, namely mutants B4, B7, B18, and the Kipas Putih (parent) variety. The results showed that the application of 10 ml L−1 eco-enzyme had an influence on the parameters of plant height, number of productive branches, number of pods, number of pithy pods, and percentage of pithy pods. The Kipas Putih G1 (B4) soybean mutant line was the best in terms of the number of pithy pods. The Kipas Putih G2 (B7) soybean mutant line was the best in the parameters of harvest age, flowering age, number of pods, and seed weight per plant. The best interaction of eco-enzyme with mutant lines was found in mutant lines G3 (B18) and G2 (B7) when given 10 ml L−1 of eco-enzyme based on the parameters of the number of productive branches and seed weight per plant.

Responsiveness of Arabica coffee cultivars to skeleton pruning in a low‐altitude region

AbstractSkeleton pruning is a type of pruning that, by cutting lateral branches (plagiotropic), allows the reinvigoration of coffee plants through the renewal of productive branches. The crop response to this management may be affected by several factors, such as the trees age, crop practices, and, mainly, the genotype. This study aimed to identify the Arabica coffee cultivars with greatest responsiveness to skeleton pruning and desirable productive and qualitative characteristics in a low‐altitude region. The experiment was conducted in northeastern São Paulo state, Brazil, at an altitude of 565 m. The experimental design was randomized blocks with four replicates, and the treatments consisted of 17 short‐stature Arabica coffee cultivars. On average, the responsiveness of the cultivars to pruning was 32% in the first year and 14% in the second year. The cultivars IAC Catuaí SH3, IAC Ouro Verde, IAC Obatã 4739, Tupi IAC 1669‐33, Catiguá MG1, Oeiras MG 6851, Pau‐Brasil MG1, Sacramento MG1, IPR 99, IPR 103, and Sabiá Tardio were responsive to skeleton pruning. Among these, Catiguá, Oeiras, Sacramento, and Sabiá stood out with pruning responsiveness above 45%. The cultivars Obatã IAC 4739, Tupi IAC 1669‐33, and Catuaí SH3 stood out in terms of yield, with an average between 40 and 50 bags ha−1. In addition to high yields, the cultivar Obatã IAC 4739 obtained grains with higher weight and sieve 17. Skeleton pruning was found to be genotype dependent and emerged as a viable alternative for revitalizing Arabica coffee cultivars in low‐altitude regions.

Temperature-Dependent Kinetics for the Reactions of Fen- (n = 2-17) and FexNiy- (x + y = 3-9) with O2: Comparison of Pure and Mixed Metal Clusters with Relevance to Meteor Radio Afterglows and Surface Oxidation.

Rate constants and product branching fractions were measured from 300-600 K for Fen- + O2 (n = 2-17) and for 300-500 K for FexNiy- + O2 (x + y = 3-9) using a selected-ion flow tube (SIFT) apparatus. Rate constants for 46 species are reported. All rate constants increased with increasing temperature, and several were in excess of the Langevin-Gioumousis-Stevenson (LGS) capture rate at elevated temperatures. As with previously studied transition metal anion oxidation reactions, the collision limit is treated as the sum of the LGS limit along with a hard-sphere contribution, allowing for determination of activation energies. These values are compared to each other along with previous results for Nin-. Measured rate constants for all three series (Fen-, Nin-, and FexNy-) vary over a relatively narrow range (1-5 × 10-10 cm3 s-1 at 300 K) being at least 15% of the collision rate constant. All reaction rate constants increase with temperature, described by small activation energies of 0.5-4 kJ mol-1. The data are consistent with an anticorrelation between the electron binding energy and rate constant, previously noted in other systems. The Fen- reaction produces a larger population of higher energy electrons than do the Nin- reactions, with FexNiy- producing an intermediate amount. The results suggest that the overall rate constant is limited by a small energetic barrier located at a large internuclear distance where electrostatic forces dominate, causing the potentials to be similar across systems, while the product formation is determined by the shorter-range, valence portion of the potential, which varies widely between systems.

FISH FARMING IS A PROMISING BRANCH OF ENSURING FOOD SECURITY OF THE EARTH'S POPULATION

Based on marketing research, it has been proven that aquaculture is one of the fastest growing branches of food production in the world. The main method of increasing fish productivity in ponds is fish feeding, which is an objective reality with high intensification of fish farming. With the intensification of production processes, the role of feeding is constantly increasing, and the cost of feeding in the cost price of fish is about 40% and has an upward trend. In this connection, the problem of rational feed use becomes extremely important. It is justified that the use of high-quality feed and feed additives in the diet of fattening animals significantly increases the productivity and profitability of the operation of livestock, poultry, and fish farms. 160 factories are engaged in the compound feeds production in Ukraine, the production capacity of which is 7.5 million tons per year. The specified indicator should be realistically increased to 15 million tons of finished products per year. It is established that we will need to produce 60 percent more food by 2050 to feed the world's 9.3 billion people according to estimates compiled by the Food and Agriculture Organization (FAO). Therefore, animal protein production is expected to increase with this increase. According to IFIF estimates, the world production of compound feeds has reached more than 1 billion tons per year. Top 10 countries in world compound feed production in 2021–2022 are presented (according to Alltech Agri-Food Outlook 2023). The structure of compound feeds production by types of agricultural animals and poultry in the world in 2022 is summarized. It is proved that the production of fish compound feeds continues to grow in all the world regions. In the world (as well as in Ukraine), fishing and aquaculture play and will play a significant role in the coming centuries in ensuring the food security of the global population. It is necessary to make changes in policy, management, stimulate innovation and investment to the industry to ensure the food security of the planet through fisheries and aquaculture. It is established that the world volume of aquatic bioresources production is constantly growing and in 2022 reached the value of 176 million t/year. More than 150 million tons of aquatic biological resources were used for human consumption. In the conditions of the formation of market relations, against the background of significant costs for feed, feeding fish should be based on careful calculations, the logical conclusion of which should be economic expediency. On the basis of the marketing research of the situation on the market of feed supplements, a shortage of protein vitamin supplements and complete feeds for domestically produced fish was revealed. The restraining factors for the use of foreign supplements are their cost and interruptions in supply.
