Effect of main cultivation methods in dry rainfed conditions on the amount of weed under winter wheat

Relevance. Against the background of predecessors, soil cultivation and nutritional conditions, weeding of the area under Barakatli 95 durum wheat variety was studied and the results obtained are given in the article. Thus, high weeds in the field reduce the quantity and quality of crops. One of the main factors preventing this is the application of proper cultivation methods appropriate to the region. This is one of the most important and urgent issues in agriculture.Methodology. The research was conducted in a 3-factor (2×3×3) field experiment in a short-rotation crop rotation (pea-wheat-wheat) located at the Jalilabad Regional Experimental Station in the rainfed conditions of South Mugan. The amount of weeds in the field was studied in the first decade of March and April by counting weeds per 1 m2 from different parts of the field according to the options.Results. The results of the 3-year study (average for 2019–2021) showed that the effect of predecessors, soil cultivation and nutritional conditions on the amount of weeds under winter wheat was different. Among the cultivation options, relatively high weeding soil was obtained with a heavy disc harrow at a depth of 10–12 cm in the form of 1 disc, and against the background of feeding conditions, N60P60 + 10 tons of manure on all three cultivations, and the least weeding was observed in the variant where N90P60K45 fertilizer norm was applied in 2 discs at a depth of 10–12 cm with a heavy disk trowel after the pea predecessor.

Growing cotton in China.

Penataan Lahan Pekarangan Untuk Mendukung Budidaya Lebah Madu di Desa Gelangsar, Kabupaten Lombok Barat

The resident's yard of Gelangsar Village generally has not been used optimally. In some parts of the yard are overgrown with shrubs whose benefits are not yet known. This program aims to introduce yard management methods that can provide economic benefits, namely the innovation of flowering plant gardens to support honey bee cultivation. The method used in this program is socialization and the formation of a pilot project. The socialization focused on introducing the arrangement of the yard with flowering plants. The pilot project was made on the land of one of the partner residents. In this pilot project, innovations in planting flowering plants with vertical garden and honey bee cultivation methods are applied. Through this pilot method, it is hoped that the people of Gelangsar Village can apply the innovations offered independently. This program has been successfully implemented. Partner residents are willing to apply the innovation of a combination of flowering plant gardens and honey bee cultivation.

Effect of different management techniques on bird taxonomic groups on rice fields in the Republic of Korea

Many bird species rely on the ecological functions of rice field habitats (e.g., paddy, levee, road, and ditch). However, recent intensive practices are causing rice fields to provide fewer suitable habitats. This study examined bird habitat usage and how it is affected by cultivation methods (e.g., eco-friendly vs conventional fields). Eco-friendly and conventional rice fields in the midwestern region of the Republic of Korea were surveyed from January 2014 to December 2016, and the species presence, number of birds, and locations of observed habitats were recorded. It was found that shorebirds and herons used more eco-friendly rice paddies with lower or no pesticide and/or herbicide use, while waterfowl used paddy habitats more than the other habitats, regardless of the amounts of pesticides and/or herbicides used. Land birds used ditches or roads in conventional rice fields more than those in fields that used pesticides and/or herbicides. Pesticide and/or herbicide use affected bird taxonomic groups differently. Consequently, the use of habitats by different bird taxonomic groups varied depending on the crop cultivation as well as the cultivation methods. These results provided valuable information for managing rice fields, which serve as habitats for birds.

Plant Growth Promotion Diversity in Switchgrass-Colonizing, Diazotrophic Endophytes

Endophytic nitrogen-fixing (diazotrophic) bacteria are essential members of the microbiome of switchgrass (Panicum virgatum), considered to be an important commodity crop in bioenergy production. While endophytic diazotrophs are known to provide fixed atmospheric nitrogen to their host plant, there are many other plant growth-promoting (PGP) capabilities of these organisms to be demonstrated. The diversity of PGP traits across different taxa of switchgrass-colonizing endophytes is understudied, yet critical for understanding endophytic function and improving cultivation methods of important commodity crops. Here, we present the isolation and characterization of three diazotrophic endophytes: Azospirillum agricola R1C, Klebsiella variicola F10Cl, and Raoultella terrigena R1Gly. Strains R1C and F10Cl were isolated from switchgrass and strain R1Gly, while isolated from tobacco, is demonstrated herein to colonize switchgrass. Each strain exhibited highly diverse genomic and phenotypic PGP capabilities. Strain F10Cl and R1Gly demonstrated the highest functional similarity, suggesting that, while endophyte community structure may vary widely based on host species, differences in functional diversity are not a clearly delineated. The results of this study advance our understanding of diazotrophic endophyte diversity, which will allow us to design robust strategies to improve cultivation methods of many economically important commodity crops.

Prospects for the use of plant materials in creating biodegradable eco-friendly packaging

This article provides information on the expansion of the base of vegetable raw material used in the packaging industry. During literature research the following criteria were considered: biodegradability, cheapness, availability, a sprouting area, an impact of used materials on condition of other industries. Plant-derived polysaccharides are contemplated as a source of biodegradable substances. The main subjects of research are plants with medicinal properties, invasive, technical and agricultural crops. The process for producing polysaccharide-based films was also examined. The possibility of introducing technologies into production was assessed. Conclusions are based on the impact of all stages of the process (collection, recycling, receiving and reusing) on the environment. Cogeneration technologies, pharmaceutical wastes and biotechnological biomass cultivation methods usage are taken into account to obtain efficient production.
