Abstract
The method and technology were developed to study the influence of an average diameter, mass and rolling friction of hawthorn fruits on the moisture content during the drying process. It was established that the fruits of smoothed hawthorn (Crataegus oxyacantha L.) have a large unevenness in diameters of 11 mm - 21 mm and weight of 1.3 g - up to 4.2 g. The average diameter of hawthorn fruits decreases from 16 to 12.5 mm with a decrease in moisture content from 74.9 to 14%; the coefficient of rolling friction of hawthorn fruits on the surface of the working chamber increases from 0.12 to 0.31 with a decrease in moisture content from 74.9 to 14%. The results of these studies of hawthorn fruits can be used in the future when designing drying plants and improving drying technology.

Abstract
It is known that vegetables are sources of vitamins, biologically active substances, antioxidants and other vital micronutrients. In particular, pumpkin vegetable crops (zucchini, squash) contain all the necessary mineral salts, vitamins, trace elements, pectin substances, ascorbic acid and not too many sugars. Varieties of vegetable crops are characterized by a diverse biochemical composition and are suitable to various degrees for obtaining processed products for therapeutic, preventive and functional purposes. The article considers the assortment of zucchini and squash by yield and the most important indicators of the biochemical composition of the fruit: the content of dry substances, sugars, vitamin C; the accumulation of nitrates in the fruit. High water content of zucchini and squash fruits (94-96%), low sugar content ( 1.5-3.5%) were found. Squash has a higher yield (25-90 t / ha), compared to zucchini (4-11 t/ha). Nevertheless, zucchini contain 3-4 times more vitamin C in the fruit and accumulate 3-4 times less nitrates than squash, having almost 10 times more of vitamin value. At the same time, squash is 2-3 times less than zucchini, accumulating nitrates. Of the 7 studied varieties of zucchini, the hybrid Belogor F1 and the variety Tsukesha were distinguished, which have high yield, high fruit quality and vitamin value. Of the 15 studied varieties of squash, the varieties Perlinka, Pyatachok and Tabolinsky were identified, which have high yields, high fruit qualities and vitamin value, and weakly accumulate nitrates.

Abstract
The potential possibility of using coherent optics for non-destructive testing to modify the microstructure of the surface of apples under the influence of chemical factors was studied. The model objects included solar and shade sides of fruits of Antonovka Common variety, untreated (control) and treated with diphenylamine (DPA). The amplitude-phase parameters of laser radiation reflected from the fruit surface were evaluated using a polarization shearing interferometer. It was experimentally shown that by the intensity and degree of coherence of the reflected laser radiation of the surface of apples, it is possible to register the anatomical and morphological characteristics of their tissues. It was revealed that after two months of storage, the spatial coherence of light scattering of the shadow side of an apple is higher than that of the solar, and the surface of apples treated with diphenylamine has a higher coherence of light scattering of the surface of both the solar and shadow sides. It was shown that the transpiration of apples treated with diphenylamine exceeds the transpiration of control apples.

Abstract
The increase in the area of orchards of intensive fruit crops in the Russian Federation is one of the priority tasks of horticulture. This requires a huge amount of quality planting material. Digging remains one of the laborious and responsible operations in the production of seedlings of fruit crops. Grubbers and diggers of various producers are used for continuous digging of seedlings. After this, the dug-in seedlings are manually removed from the soil and row and only after that the next run of the unit is possible. The authors proposed a means of mechanization, selective digging of individual varieties or rows of plants, with a winch traction using a cable. The paper provides a comparative analysis of mechanization means for selective digging of seedlings and presents a diagram and results of field tests of two types of devices to perform this operation.

Published: November 2021

Abstract
The article presents data on the influence of various types of spherical disks on the discarding of soil in the horizontal and vertical planes during its processing. These studies were conducted in order to optimize the selection of working bodies of disk tillage machines in terms of resistance and processing quality. Three types of disks were used in the comparative analysis. Two types of discs with cutouts and one solid spherical disc. On one type of disk, the cutouts are made in the form of circular arcs, and on the other-in the form of arcs of a logarithmic spiral. The conducted studies have shown that within the working surface of the disk, the trajectories of movement of soil particles under the influence of the three types of disks under study differ little from each other. Although it can be noted that the steeper rise of the trajectory in the vertical plane provides a solid disk, and the smallest rise of the trajectory - at the disk with cutouts in the form of a logarithmic spiral. In the horizontal plane, the longitudinal movement of the soil mass is less in disks with cutouts, especially in a disk with cutouts along the arc of a logarithmic spiral. As a result of these studies, it was revealed that the disk working bodies with cutouts on the cutting edge in the form of arcs of a logarithmic spiral showed the best quality and energy indicators.

Published: November 2021

Abstract
Understanding the possible climate risks and potential economic losses of agribusiness in different regions is becoming a determining factor in the strategic planning of agricultural activities in the context of global warming. The purpose of this work was to assess the climate risks for agriculture in Russia. The study was conducted using techniques and tools of multivariate correlation analysis. The authors investigated the influence of deviations of the average monthly amounts of temperatures and precipitation from the average long-term values on the deviation of grain yields, using a set of data for 17 regions of the Central Federal district of Russia for the period of 2000-2019. The results showed that a smooth change in the parameters of heat and precipitation does not significantly affect the yield of grain crops. At the same time, increasing annual temperature variability and precipitation significantly reduce yields. An increase in the frequency of extreme events causes a growth in the probability of environmental and economic damage and the magnitude of climate risks. The maximum level of climate risk requires an appropriate adjustment of the agribusiness development strategy and the creation of an institution in society of fair compensation for damage caused by global warming factors.

Abstract
Due to global shifts in climate, studies in contrasting conditions of two natural and climatic zones are of particular interest: (1) subzone of mixed and broad-leaved forests, (2) south-steppe subzone. In the period 2019-2020, 308 plant species from 56 families were surveyed. Phytopathogens damage plants, and therefore increase the loss of quality of plant materials. The frequency of occurrence of mycoses in autumn is 2-14 times higher than in spring-summer observations. The activity of phytopathogenic fungi of the genera of Fusarium (the causative agent of fusarium), Puccinia (rust), Phoma (phomosis), Rhizoctonia (scab), Verticillium (tracheomycotic or vascular wilting) increases. Differences in dominant micromycetes from the point of view of geography were determined: zone 1 (forest) - Alternaria spp., Chaetomium spp., Fusarium spp., F. avenaceum (Fr.) Sacc., (Mart.) Sacc., Heterosporium iridis (Fautrey & Roum.) JE Jacques, Phoma spp., Stemphylium spp., Verticillium spp.; zone 2 (steppe) – Alternaria spp., Botrytis spp., Cladosporium spp., Fusarium avenaceum, Fusarium spp., Peronospora spp., Phoma spp., Pullularia spp., Septoria spp. Screening of pesticides (biological fungicides) showed the effectiveness of preparations based on Pseudomonas fluorescens, Bacillus subtilis or Streptomyces griseus in limiting the growth of the mycelium of phytopathogenic fungi.

Published: November 2021

Abstract
In this paper, we analyse the suitability of various elements and their composition for microwave absorption. This is done by developing a mathematical model based on transmission line theory, polarizability and dielectric and magnetic response of the material. The inputs to this model are the desired specifications of the absorber like reflection loss, resonance frequency and bandwidth. The corresponding output parameters are the range of the atomic radii and magnetic dipole moment of suitable elements and their effective energy parameters. This mathematical model has been verified for compounds like oxides and ferrites that have been proven posses microwave absorption properties through previous experimental research. This mathematical model has been verified for compounds like oxides and ferrites that have been proven to possess microwave absorption properties through previous experimental research. Through numerical computations, we propose new material compositions with various elements that can be used as effective microwave absorbers.
Spatiotemporal monsoon characteristics and maize yields in West Africa
Authors: Shiu Janice , Fletcher Sarah , Entekhabi Dara 
Published: November 2021

Abstract
To assess the vulnerability of rainfed agriculture in West Africa (WA) to climate change, a detailed understanding of the relationship between food crop yields and seasonal rainfall characteristics is required. The highly seasonal rainfall in the region is expected to change characteristics such as seasonal timing, duration, intensity, and intermittency. The food crop yield response to changes in these characteristics needs greater understanding. We follow a data-driven approach based on historical yield and climate data. Such an approach complements model-based approaches. Previous data-driven studies use spatially and temporally averaged precipitation measures, which do not describe the high degree of spatial and temporal variability of the West African Monsoon (WAM), the primary source of water for agriculture in the region. This has led previous studies to find small or insignificant dependence of crop yields on precipitation amount. Here, we develop metrics that characterize important temporal features and variability in growing season precipitation, including total precipitation, onset and duration of the WAM, and number of non-precipitating days. For each temporal precipitation metric, we apply several unique spatial aggregation functions that allow us to assess how different patterns of high-resolution spatial variability are related to country-level maize yields. We develop correlation analyses between spatiotemporal precipitation metrics and detrended country-level maize yields based on findings that non-climatic factors, such as agricultural policy reform and increased investment, have driven the region’s long-term increase in maize yields. Results show that that the variability in the number of days without rain during the monsoon season and the lower bounds to the spatial rain pattern and end to the monsoon season are most strongly associated with maize yields. Our findings highlight the importance of considering spatial and temporal variability in precipitation when evaluating impacts on crop yields, providing a possible explanation for weak connections found in previous studies.
