Leguminous Crops

Faba beans are considered to be one of the most important leguminous crops. The species is characterized by high nutritional value, in terms of both energy and protein content, which makes it suitable for food and feed production. Fungal diseases are among the key biotic factors responsible for a decline in faba bean yields. In this study, the yield and health status of faba bean seeds from the region of Warmia and Mazury (WM) and the region of Lower Silesia (LS), in Poland, were determined. Correlations between weather conditions vs. the yield of faba bean seeds and the occurrence of saprophytic and pathogenic fungi were analyzed. The study revealed that temperature and precipitation influenced the development and yield of faba beans in successive growth stages. Temperature exerted the greatest effect on the yield of faba beans during inflorescence emergence (BBCH 55-Biologische Bundesanstalt, Bundessortenamt and CHemical Industry), whereas the effect of precipitation was the maximum at the 4–5 leaves unfolded stage (BBCH 34–35) and at the end of flowering (BBCH 69). The occurrence of saprophytic, pathogenic, and toxin-producing fungi was influenced by temperature and precipitation in the flowering stage (BBCH 61–64).

AbstractVicia faba (faba bean) is one of the most significant leguminous crops. The faba bean is specialized by maximum nutritional value, in energy and protein content, which leads it to be suitable for food and feed production. Diseases caused with fungi are amongst the biotic factors responsible for decreasing in faba bean yields. In this work, Cladosporium isolates were recorded in cultivated faba bean leaves and pods collected from markets in Qena, Upper Egypt; morphological features and molecular characterization based on actin gene were performed. The ability of the pathogens to cause disease in faba bean seedlings and the biocontrol method to avoid the pathogenic effect of Cladosporium were determined. Results showed that Cladosporium is the main genera isolated from faba beans, and the morphological criteria showed presence of three species complex groups of Cladosporium (C. cladosporioides, C. herbarum and C. sphaerospermum) and the confirmation with molecular characterization revealed the existence of four species in the three groups. All the 26 tested strains of Cladosporium were able to cause leaf lesions on Vicia faba seedlings with different levels. Chaetomium globosum is a biocontrol agent could inhibit the growth of the majority strains of Cladosporium.

The objective of the study was to determine the time of occurrence of the emergence, budding, fruiting and seed shedding stages, as well as the degree of advancement of the white goosefoot fruiting and diaspores shedding stages in fodder beet, spring wheat and faba bean crops under mechanical and chemical weed control. Phenological observations were conducted in the years 2000-2002 at 10-day intervals, starting from the day of crop sowing on alluvial soil made of light loam. Chemically weed controlled objects were treated with herbicides: fodder beet - lenacil 80%; spring wheat - MCPA 30% + dicamba 4%; faba bean - linuron 50%. It was proven that the times of occurrence and the scale of the studied phenological stages of white goosefoot depended on the crop species, the in-crop weed control method and the pattern of weather conditions in the study years. White goosefoot had the most favourable conditions of growth in the fodder beet crop. The herbicides in the fodder beet and faba bean crops delayed the emergence and the time of occurrence of successive white goosefoot growth stages. These agents also decreased the degree of diaspores shedding by the weed species studied. The most white goosefoot specimens shed fruits on the mechanically weed controlled plots. The diaspores dissemination was promoted by a warm and moist growing season.

The health status of seeds of three lupine species (white lupine, narrow-leaved lupine, and yellow lupine) from different regions of Poland was investigated. Seeds were analyzed by microscopic method and PCR. The examined lupine seeds were colonized by saprotrophic fungi of the genera <em>Alternaria</em>, <em>Cladosporium</em>, and <em>Penicillium</em>, and pathogenic fungi of the genera <em>Fusarium</em>, <em>Botrytis</em>, <em>Mycosphaerella</em>, and <em>Colletotrichum</em>. The relative frequency (RF) of fungi detected on lupine seeds from the regions of Kujawy, Wielkopolska, Lower Silesia, and Warmia and Mazury was determined. The highest RF values of pathogenic fungi were noted in Lower Silesia in 2012 and 2013, and in Warmia and Mazury in 2011. The RF values of pathogenic and saprotrophic fungi on lupine seeds harvested in different regions of Poland were affected by weather conditions. PCR analyses revealed the presence of <em>Tri</em> genes in the seeds of narrow-leaved lupine. The analyzed seeds were relatively free of pathogenic fungi and could be used for sowing and feed production.

In the frame of EU 7th Research Framework Programme of The European Union project EUROLEGUME (Enhancing of legumes growing in Europe through sustainable cropping for protein supplay for food and feed) two Rhizobium leguminosarium strains alone and in mixture were examinated to evaluate the influence on yield formation of faba bean (Vicia faba L.) ‘Lielplatones’. The field experiment was carried out at the Institute of Agricultural Resources and Economics between 2014 -2016 in the organic cropping system field. The beans seeds were treated with rhizobia fungi by soaking in bacteria suspension for 30 minutes before sowing. A plant high was measured at the beginning of flowering (BBCH 61- 64), at the beginning of forming pods (BBCH 71- 75) and at the beginning of maturity (BBCH 81- 85). The inoculation of plant seeds promotes a slight increase in the plant length. The highest yield was from seeds inoculated with strain R2. There were no significant differences between tested strains. The results of this investigation indicate that rhizobium inoculation is a recommendable management tool for faba beans generally but effectiveness of rhizobial strains strongly depending climate conditions. Seed treatment with Rhizobium contributed to an increase in the quantity of nitrogen in the soil.

Faba bean necrotic yellow virus (FBNYV) was not detected during 1994 to 1996 field surveys of faba beans (Vicia faba L.) in Spain (1). In 1997, however, one sample with symptoms of necrosis, collected in Baleares, was tested using ELISA (enzyme-linked immunosorbent assay) and was positive for both Tomato spotted wilt virus (TSWV) and FBNYV. FBNYV is a single-strand DNA virus that is transmitted by aphids and is the main virus disease of broad bean in North Africa and West Asia (2). During 1997 to 1999, faba bean plants with symptoms of necrosis, yellowing, small leaves, and stunting were collected from several fields in the Murcia Region (Spain) and were analyzed using ELISA. To detect FBNYV, we used monoclonal 2E9 supplied by H. J. Vetten (Institute of Plant Virology, Microbiology and Biosafety, BBA, Braunschweig, Germany). Of 700 samples analyzed, 34 were positive for FBNYV. Of the 34 positive samples, 12 tested positive, using commercial antiserum from Loewe, Inc. (Munich) for mixed infections with TSWV. FBNYV was transmitted to healthy faba bean plants by aphids (Acyrthosiphon pisum) in greenhouse experiments and was confirmed by ELISA. Preliminary epidemiological data showed a gradual increase in the number of plants infected with time in the same field. Aphid transmission of FBNYV to faba beans has established the disease in Spain and is a potential threat to other leguminous crops. This is the first report of a nanovirus in Europe.

The results of the study of 12 varieties and promising lines of glumaceous oat in the competitive variety testing of the FASC of the North-East (Kirov region) in the period from 2018 to 2020 are presented. The purpose of the research is to assess the productivity, ecological plasticity and stability of the genotypes of glumaceous oat for feed and universal use in the conditions of the Volga-Vyatka region. The dependences of grain yield and dry matter harvesting on the state of agro-climatic resources (HTC), temperature and precipitation are established. The contrasting weather conditions during the years of research allowed to conduct the most complete assessment of the studied genotypes. The most favorable conditions for the formation of a high yield of green mass of oat were formed in 2020 (Ij=3.76), grain - in 2019 (Ij=1.35). The average degree of positive dependence of green mass yield on the height of oat plants was revealed (r=0.51). The variety of the high-intensity type of the universal direction Medved, promising lines of the mowing direction (178h13 and 245h14) are distinguished.

Vertical stratification of forests results in the occurrence of different arthropod assemblages between the vertical layers. Fallen arthropods from the canopy layers (i.e., “arthropod rain”) are additional food sources for predators thriving on the forest floor (FF). However, the abundances of arthropods are strongly affected by weather conditions and vertical stratification. Therefore, in this study, we investigated the vertical distribution of arthropod assemblages and effects of temperature and precipitation on the arthropod rain in a temperate conifer (Cryptomeria japonica) forest. Arthropods were collected by water-pan traps and trunk-sticky traps in the upper canopy (UC; 16 m), lower canopy (10 m), and FF (0.5 m). Among the fallen arthropods collected by water-pan traps, wandering detritivores, and herbivores were more abundant ranging from the FF to the UC, whereas the abundance of wandering predators (mainly spiders) was similar in the upper and lower canopies. However, detritivores, herbivores, and predators showed the highest abundance in the UC among the flying arthropods. Wandering arthropods moved upward from the FF toward the tree trunks more frequently than downward, indicating the importance of arthropod immigration from the ground to arboreal habitats. Temperature and precipitation had different effects on fallen and moving arthropods among different taxonomic groups. Flying arthropods were affected only by temperature, while wandering detritivores and herbivores were affected by precipitation and temperature. Thus, the abundance of wandering and flying arthropods differed among the vertical layers of a temperate conifer forest; additionally, arthropod rain was closely associated with weather conditions.
