ABSTRACT: Coffee, a globally traded and profitable commodity, is pivotal in many countries' economies and social development. In the Vale do Ribeira, a region of significant socio-environmental importance, coffee farming has the potential to boost local family agriculture through the diversification of agricultural production, with a focus on Conilon coffee (Coffea canephora Pierre), which thrives in hot and humid climates. In this context, our study's in situ evaluation of the agronomic performance of Conilon coffee clones is of utmost importance. We assessed the vegetative growth, incidence of pests and diseases, productivity, and grain ripening of various Conilon coffee clones in Registro, located in the humid subtropical environment of Vale do Ribeira. Clones 401 and 410 demonstrated superior vegetative growth. Pests and diseases, such as leaf miner, Phoma, and Cercosporiosis, were more prevalent during higher temperatures, while rust was a concern in cooler temperatures. The most productive clones were 13V, 407, 403, and 409, with a higher percentage of grains in the "cherry" stage, making them the most promising for cultivation in the region.

The review article is devoted to the analysis and assessment of the impact of climate change on the efficiency of agricultural commodity production in the Republic of Tatarstan and ameliorative measures to overcome its negative impact on the performance of the agrarian sphere. Studies of agrometeorological data for 1900–2021 testify to the impending growth of climate aridity in the region. The analysis of modern conditions of meliorative industry development and its economic efficiency has shown that 1.5% of arable land area under irrigation allows to produce up to 18% of crop production in the republic, which certainly indicates a high degree of its efficiency. It has been established that the natural-climatic potential of the republic allows to bring the scale of irrigation reclamation up to four hundred thousand hectares, and to guarantee the need of the Republic of Tatarstan in foodstuffs of own production it is necessary to bring the volume of irrigated lands up to 150 thousand hectares, which allows to speak about the high export potential of the republic. High efficiency of land reclamation measures and existing measures of state support unfortunately do not provide its implementation in production activity of agrarian business entities due to the need for preliminary overly bureaucratized survey works, approvals for obtaining design and estimate documentation (DED). The scientific and substantiated measures of land reclamation industry development are proposed, contributing to the preservation and restoration of soil fertility, water resources, reducing the loss of agricultural land area, a multiple increase in the economic efficiency of agricultural production.

Relevance. Accidental disease is an actual disease of horses in many countries, including Russia, where cases of the disease have been registered in 16 administrative territories. In the Russian Federation, the proportion of accidental illness is about 47% in the general infectious and parasitic pathology of horses. The mortality rate is high, up to 30–50%, sometimes higher. The treatment of sick animals is prohibited.The purpose of the study is to study the epizootic situation of accidental illness in the North Caucasus and Southern Federal Districts, where a high density of horse population is registered.Methods. The epizootic situation of accidental equine disease from 2020 to 2022 was studied based on the materials of annual reports submitted by the state veterinary laboratories of the Russian Federation.The complement binding reaction (CFT) is the main method of lifetime diagnosis of accidental illness.Results. Serological studies for accidental equine disease from 2020 to 2022 were performed in all subjects of the North Caucasus and Southern Federal Districts. It has been established that the epizootic situation of accidental illness in the territory of the Southern Federal District is prosperous, and in a number of regions of the North Caucasus Federal District it is tense. Thus, specific antibodies to the causative agent of accidental disease were detected in the North Caucasus Federal District in 36 cases, including in the Republic of Dagestan — 27, in the Chechen Republic — 4, in the Kabardino-Balkarian Republic — 3, in the Karachay-Cherkess Republic — 2. Thus, the epizootic situation in the South of Russia is different.

Relevance. The safety of lambs is the most important factor affecting the efficiency of the industry. It is of particular relevance for multiple breeds. The level of dairy productivity of ewes is one of the factors affecting the growth and development of lambs, their safety before weaning. Milk productivity is positively correlated with the dynamics of the live weight of lambs.The aim of the study was to study the milk content of crossbred ( 1/2 southern meat and 1/2 Katum) and purebred (southern meat) ewes, the effect of this indicator on the growth of lambs.Methods. The objects of the study were purebred (n = 46), crossbred ( n = 30) ewes and their lambs. To determine the amount of milk produced by a ewe over 20 days, the increase in live weight of lambs during this period was multiplied by a factor of 5 (on average, up to 5 liters of milk are required for an increase of 1 kg). In multiple-fetal ewes, milk production was determined by multiplying the sum of the growth of all lambs in the litter by 5.Results. The number of lambs in the litter and the genotype of the ewes have a statistically significant effect on the live weight of lambs at birth and the milk production of ewes. Lambs born alone in a litter exceeded double lambs by 18.1% and triple lambs by 22.6% in live weight. Multiple ewes are superior in milk production to ewes with one lamb. In terms of the amount of milk produced in 20 days, ewes with triplets exceeded their peers with one lamb by 2.24 times, and with twins — 1.52 times. Crossbred (1/2 southern meat and 1/2 katumskaya) ewes are higher in milk productivity than the maternal breed.

Relevance. When forming a diet for feeding animals that are kept in modern livestock complexes, the farmer pursues an exceptionally rational approach in terms of livestock productivity and the period of productive existence of animals. First of all, the provision of these indicators forms the quality of animal feeding, expressed in the total nutritional value of the diet and the quality of mixing the components that make up its composition.Methods. The updating of the direction of scientific research was carried out on the basis of a preliminary literary review of modern publications in the international journals Journal of dairy science, Robotics and autonomous systems and Agriculture. In addition, the functionality of modern analytical equipment from world manufacturers used in agriculture was analyzed. The technical solutions of the exhibits of industry exhibitions, as well as the accompanying documentation, are considered. The existing methods for determining the homogeneity of feed mixtures for farm animals have been studied, advantages and disadvantages have been identified.Results . The existing methods for estimating the homogeneity of feed mixtures are considered. A new concept has been proposed for constructing a system for determining the homogeneity of feed mixtures by optical methods, which is based on express measurement of the optical properties of feed mixture components on the surface of a conveyor belt or mixing unit, the use of which will allow you to manage the temporary modes of mixing feeds and assess the serviceability of the machines and units used.

Relevance. Holstein dairy cattle are bred in the Sverdlovsk region, its improvement is carried out by selecting and selecting the best for further breeding. In order for them to display their genetic potential of productivity, it is necessary to ensure a balanced diet. The aim of the work was to assess the diversity of dairy characteristics in Holstein cows when using the “VivAktiv” feed additive.Methods. To conduct the study, 4 groups of calved heifers with 10 heads each were formed in a typical breeding plant for the region: a control group and three experimental ones based on the principle of pairs of analogues. The dairy productivity of cows was evaluated for the first lactation and for the calendar year by control milking once a month. The fat and protein content in milk was assessed in an average milk sample once a month from each cow. The coefficient of variability (variation) was calculated according to the generally accepted formula.Results. As a result of the conducted research, it was found that the use of the “VivAktiv” feed additive did not significantly affect the productivity of cows. The milk yield for lactation by group was 10582.3 ± 187.35, 10640.8 ± 163.89, 10293.9 ± 176.45 and 10080.1 ± 178.13 kg, respectively, the difference was unreliable and insignificant. Considering the changes in the coefficient of variation between the groups, we can note a lower variability of the trait in cows of the 2nd experimental group. The animals of the control group came in second place. The largest variety of the trait turned out to be in the 3rd experimental group. Thus, the variability of the trait is influenced by the period (month) of lactation, to some extent the duration of lactation, as well as the use of the feed additive “VivAktiv”, which had a stabilizing effect on cow yield when used at a dose of 20 g/head/day.

Published: May 2024

Relevance. Optimization of the mineral nutrition of plants of anthocyanin-containing potato varieties requires an analysis of their yield, elemental composition and nutrient removal. In the work, these indicators were studied for three varieties with different colors of the pulp of tubers (Gala, Syurpriz and Severnoe Siyanie).Methods. The research was carried out in a single-factor experiment on the experimental field of the Tver State Agricultural Academy in 2023 on well-cultivated sod — medium podzolic light loamy soil. 3 varieties have been studied: Gala, Syurpriz and Severnoe Siyanie . The repetition in the experiment is 3 times. Intensive cultivation technology was observed. The yield of tubers, the content of dry matter, crude ash, nitrogen, potassium, phosphorus, iron, copper, zinc, cobalt and boron in them — according to standard methods prescribed in the relevant GOST standards. The content of calcium and magnesium in tubers was determined by the complexometric method.Results. The anthocyanin-containing varieties Syurpriz and Severnoe Siyanie were characterized by higher yields (by 4.2–5.2 t/ha) and the content of nitrogen, calcium, iron, copper, zinc, cobalt and boron in tubers than in the Gala variety. Due to this, they were distinguished by a higher removal of two macronutrients — nitro-gen (76.14–77.28 kg/ha) and calcium (1.95–2.78 kg/ha), five trace elements — iron (112.63–151.29 g/ha), copper (18.79–20.41 g/ha), zinc (66.65–69.84 g/ha), cobalt (0.75–0.77 g/ha) and boron (29.19–37.46 g/ha). The obtained removal indicators can be used to calculate the approximate doses of fertilizers.

Abstract

Acinetobacter baumannii is a non-fermentative Gram-negative bacterium that can cause nosocomial infections in critically ill patients. Carbapenem-resistant A. baumannii (CRAB) has spread rapidly in clinical settings and has become a key concern. The main objective of this study was to identify the distribution of integrons and biofilm-formation-related virulence genes in CRAB isolates. A total of 269 A. baumannii isolates (219 isolates of CRAB and 50 isolates of carbapenem-sensitive A. baumannii (CSAB)) were collected. Carbapenemase genes (bla
KPC, bla
VIM, bla
IMP, bla
NDM, and bla
OXA-23-like) and biofilm-formation-related virulence genes (abal, bfms, bap, and cusE) were screened with PCR. Class 1 integron was screened with PCR, and common promoters and gene cassette arrays were determined with restriction pattern analysis combined with primer walking sequencing. Whole-genome sequencing was conducted, and data were analyzed for a bla
OXA-23-like-negative isolate. All 219 CRAB isolates were negative for bla
KPC, bla
VIM, bla
IMP, and bla
NDM, while bla
OXA-23-like was detected in 218 isolates. The detection rates for abal, bfms, bap, and cusE in 219 CRAB were 93.15%, 63.93%, 88.13%, and 77.63%, respectively. Class 1 integron was detected in 75 CRAB (34.25%) and in 3 CSAB. The single gene cassette array aacA4-catB8-aadA1 with relatively strong PcH2 promoter was detected in class 1 integrons. The bla
OXA-23-like-negative CRAB isolate was revealed to be a new sequence type (Oxford 3272, Pasteur 2520) carrying bla
OXA-72, bla
OXA-259, and bla
ADC-26. In conclusion, bla
OXA-23-like was the main reason for CRAB’s resistance to carbapenems. A new (Oxford 3272, Pasteur 2520) CRAB sequence type carrying the bla
OXA-72, bla
OXA-259, and bla
ADC-26 was reported.
A Modified Reactive Powder Concrete Made with Fly Ash and River Sand: An Assessment on Engineering Properties and Microstructure

Published: May 2024

Containing a high quantity of both fine powders and steel fiber makes reactive powder concrete (RPC) a unique kind of ultra-high strength concrete. However, the cost of manufacture, shrinkage, and hydration heat are increased when silica fume and cement are used in significant amounts. To mitigate these negative consequences and the environmental impact, this study assessed the use of fly ash (FA) with high volume combined with natural-fine river sand (NFRS) in the manufacturing of RPC. FA was utilized to partially substitute cement at 0, 20, 40, and 60 wt% in RPC mixtures that had a set water/binder ratio of 0.2. Thermal conductivity, porosity, water absorption, and compressive strength tests were performed. Furthermore, RPC's microstructure was examined using a scanning electron microscope (SEM). This study also included a cost and global warming potential analysis of RPC production. Test results indicated that a modified RPC with a 60 MPa compressive strength value could be created by using NFRS and a large amount of FA. In comparison to the reference mixture, a higher compressive strength, reduced water absorption, and lesser porosity were observed in RPC when the FA replacement amount was less than 40%. Many FA particles did not engage in the hydration reaction when the FA replacement level was more than 40%, which had a detrimental impact on the RPC's characteristics. In general, using FA to produce RPC has certain benefits for the economy and the environment. It is recommended that 40% of FA be used in actual practice.

The objective of the current work was to synthesize and characterize ferromagnetic activated carbon from peanut shells (PSs) and apply it for the degradation of methyl orange (MO) following the heterogeneous Fenton process. PSs were activated with phosphoric acid and potassium hydroxide at 1:1, 1:2, and 1:3 solid/liquid activation ratios and different concentrations (0.5, 1, and 1.5 M) and pyrolized at 500°C. Based on the iodine indexes, KOH-activated carbon adsorbents exhibited higher porosity than the H3PO4-activated adsorbents. KOH-activated carbon at a 1:3 activation ratio (iodine value 591 mg/g) was selected for magnetization using iron (II) ions and catalytic mineralization of MO dye. The ferromagnetic activated carbon (AC-PS@FeII) was characterized using Fourier-transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray (EDX) analysis, and nitrogen-adsorption BET measurements. AC-PS@FeII contained ferromagnetite with a cubic spinel structure and a specific area of 181.96 m2·g–1. AC-PS@FeII degraded MO with a degradation efficiency of 99.22% at pH 2, 4 g/L of catalyst dosage, and a 50-min contact time. The results of recyclability tests, using distilled water, revealed a slight decrease in degradation capacity after four runs, indicating that the developed catalyst was appreciably stable. The hetero-Fenton catalyst from peanut shells could be an ideal catalyst for treating wastewater contaminated with dyes as a path toward a circular economy.
