Innovate And Create Novel Mycoinsecticide System To Promote Green Development Of Agriculture, Ding Ding, Feng Jiang, Lili Cao, Le Kang

Bulletin of Chinese Academy of Sciences (Chinese Version)

The long-term irrational use of chemical pesticides has led to severe ecological, environmental, and human safety concerns, although chemical pesticides play an important role in increasing crop yields. In response, China has issued a series of policies to reduce the use of chemical pesticides, aiming to ensure food and agricultural safety while promoting high-quality agricultural development. Reducing the usage of chemical pesticides must be complemented by the adoption of biological pesticides. Globally, biological pesticides currently account for approximately 40% of total pesticide usage in many countries. Mycoinsecticide, characterized by their environmental friendliness, sustainability, and low resistance development, represents an important …

The Indigenization Of Tobacco Farming And Its Challenges In Iringa District: 1960s–1980s, Emmanuel Kihongo

Journal of Humanities and Social Sciences

This paper is about the politics of indigenizing tobacco farming and the challenges associated with it during the post-colonial era. It examines the initiatives of government in facilitating the process, and how the bodies entrusted to ensure its implementation failed to achieve the intended goal. Tobacco farming in Africa and Tanzania has a complex history. Since this crop is essentially labour- and capital intensive, its beginning in colonial Tanganyika, and Iringa in particular, was dominated by settler farmers. The paper progressively narrates this history, especially on how it became a popular crop among indigenous smallholders in Iringa from 1961. It …

Tissue‑ And Time‑Dependent Metabolite Profiles During Early Grain Development Under Normal And High Night‑Time Temperature Conditions, Nathan Abshire, Andrew L. Hauck, Harkamal Walia, Toshihiro Obata

Department of Agronomy and Horticulture: Faculty Publications

Background Wheat grain development in the first few days after pollination determines the number of endosperm cells that influence grain yield potential and is susceptible to various environmental conditions, including high night temperatures (HNTs). Flag leaves and seed-associated bracts (glumes, awn, palea, and lemma) provide nutrients to the developing seed. However, the specific metabolic roles of these tissues are uncertain, especially their dynamics at different developmental stages and the time in a day. Tissue- and time-dependent metabolite profiling may hint at the metabolic roles of tissues and the mechanisms of how HNTs affect daytime metabolic status in early grain development. …

Biological Lags And Market Dynamics In Vertically Coordinated Food Supply Chains: Hpai Impacts On U.S. Egg Prices, James L. Mitchell, Jada M. Thompson, Trey Malone

Department of Agricultural Economics Faculty Publications

It is well known that livestock production involves long biological lags. Failure to account for these biological lags can result in the misspecification of supply chain relationships and adjustments to market shocks, which can have significant implications for policy decisions. An example is the 2022 Highly Pathogenic Avian Influenza (HPAI) event that caused high mortality rates in domestic poultry supply chains and reduced egg production. We use the 2022–2023 HPAI event to highlight the implications of misspecification of disease dynamics in agri-food systems. Specifically, we examine the impact of HPAI on U.S. egg prices in 2022–2023. To do this, we …

Enhanced Photocatalytic Degradation Of Rhodamine B Dye (Rhb), Fluorescein Dye (Flu), And Their Mixture Using Agi/Sno2 Photocatalyst, Saddam Alaskary

Chemical Engineering

AgI/SnO2 composites, synthesized via sol–gel method, emerge as highly efficient photocatalysts for degrading rhodamine B (RhB), fluorescein (Flu), and their mixtures, shifting photocatalytic activity into the visible spectrum. Characterized by XRD, FESEM, DRS, EDX, mapping, TEM, BET, and XPS, these nanocomposites, especially with 15% AgI, show a remarkable increase in photocatalytic efficiency for Flu, achieving a rate constant of 0.0189 min− 1 which is triple that of pure SnO2 at 0.0061 min− 1. The optimal degradation of Flu, RhB, and their mixture occurs with 0.1 g of the 15 wt% AgI/SnO2 composite. This enhancement is attributed to the Z-scheme mechanism …

Physiological And Biochemical Responses Of Maize (Zea Mays L.) Cultivars Under Salinity Stress, Nosheen Iftikhar, Shagufta Perveen, Baber Ali, Muhammad Hamzah Saleem, Mohammad Khalid Al-Sadoon

Turkish Journal of Agriculture and Forestry

Salt stress is a serious threatening factor for cereal crops such as maize (Zea mays L.) by affecting their growth and development. In the current era, the requirement for staple crops is increasing, so it is important to screen out salt-tolerant genotypes. For this purpose, a pot experiment was designed within three replications on ten different genotypes of the maize. The plants were planted in plastic pots and salt stress (0, 40, 70, 100 mM) was maintained. The salt stress induced a noticeable reduction in plant growth traits (shoot length, root length, shoot, root fresh and dry weight, and leaf …

Turkish Journal of Agriculture and Forestry

A comparative analysis was performed under in vitro conditions using Nicotiana tabacum lines overexpressing the genes of arginine decarboxylase (FvADC) and spermidine synthase (FvSPDS) enzymes. The transgenic and native lines were tested under controlled conditions and exposed to long-term treatment of arginine (150 mg/L), putrescine (10 mg/L), and spermidine (10 mg/L). Chlorophyll and lignin contents of the samples were measured spectrophotometrically, while proline, putrescine, spermidine, and spermine contents were determined using high-performance liquid chromatography methods. The experimental results showed that the arginine decarboxylase enzyme affects polyamine metabolism. As it is involved in several other biosynthetic pathways, this effect is significant …

Local Organic And Inorganic Amendments To Improve Table Grape Production In Mediterranean Vineyards Of Southern Türkiye, Semi̇h Tangolar, Simone Priori, Serpi̇l Tangolar, Meti̇n Turan, Erhan Akça

Turkish Journal of Agriculture and Forestry

In the Mediterranean Region, calcareous soils are generally considered to be of low fertility. The use of large amounts of chemicals and irrigation to compensate for low productivity reduces the producer’s net profit and degrades physical and chemical properties of the soils. As a result, the selection of adaptable genotypes is important in agriculturally limited lands. Grapevine is one of the leading crops in the Mediterranean Basin due to its high tolerance to abiotic conditions. However, the fact that the grapevine grows in extreme soils does not mean that such crop does not respond to a good nutritional program, especially …

Using Computational Modeling To Design Antiviral Strategies And Understand Plant-Virus Interactions, Hira Kamal, Muhammad Mubashar Zafar, Abdul Razzaq, Aqsa Ijaz, Zunaira Anvar, Hayat Topçu, Khalid M. Elhindi, Asif Saeed, Urooj Fatima, Xuefei Jiang

Turkish Journal of Agriculture and Forestry

Using a bioinformatics approach to identify binding pockets between proteins is a preferable method before modifying the genome to delineate host interactions with viruses. Based on extensive proteomics data in numerous databases, several interaction prediction methods are available to identify binding sites between viruses and hosts at the individual residue level, but little is known about the interaction prediction strategy for plant viruses. Begomoviruses, belonging to the family Geminiviridae, constitute a group of circular single-stranded (ss) DNA viruses that encode multifunctional proteins responsible for viral replication, causing severe diseases in multiple host plants. These viruses usually escape through plant defense …

Turkish Journal of Agriculture and Forestry

Helicoverpa armigera Hübner, 1808 (Noctuidae; Lepidoptera) is one of the major pest problems causing production constraints in both conventional and organic agricultural systems. Chemical and semichemical, along with biotechnological approaches, like the sterile insect technique, are used to manage pest populations. However, these methods raise environmental concerns. Therefore, the current study was undertaken to assess the biocontrol potential of the entomopathogenic fungal strains Beauveria bassiana, Metarhizium anisopliae, Akanthomyces lecanii, and Purpureocillium lilacinus against H. armigera. These strains, identified through morphological and molecular techniques, were evaluated for their effectiveness in controlling H. armigera. A total of eight fungal strains were identified …

Deferred Grazing And Sheep At The Break Of Season In South West Western Australia, Department Of Primary Industries And Regional Development, Western Australia

Animal production and livestock factsheets

Grazing annual pastures in the first 12 days after germination can lower the productivity of pastures during winter by removing poorly rooted plants, and by reducing plant leaf area to sub-optimal levels. The Department of Primary Industries and Regional Development (DPIRD) recommends deferring grazing of pasture paddocks at the break-of-season until feed on offer is at least 500–800 kilograms of dry matter per hectare (kg DM/ha). At this level, pasture plants are likely to be firmly rooted and have sufficient leaf area to be productively grazed.

Soil And Organic Carbon Losses By Water Erosion In Coffee-Growing Areas In Southern Minas Gerais, Brazil, Derielsen Brandão Santana, Guilherme Da Silva Rios, Guilherme Henrique Expedito Lense, Felipe Gomes Rubira, Flávio Roberto Araújo Franceschi, Velibor Spalevic, Joaquim Ernesto Bernardes Ayer, Ronaldo Luiz Mincato

Turkish Journal of Agriculture and Forestry

Organic carbon performs essential functions in soils. Soils act as sources or sinks of atmospheric organic carbon. Agricultural management influences soil organic carbon, impacting climate change. One of the crops most vulnerable to climate change is coffee. Brazil is the world's largest coffee producer, with a predominance of management under a conventional system, with sloping terrain and the absence of conservationist practices. The absence of conservationist practices results in an increase in soil loss rates due to water management and carbon emissions, as well as a reduction in coffee production. This paper aimed to estimate soil and organic carbon losses …

Effects Of Nutrient Solution Strength, Pgpb, And Mycorrhizal Inoculation On Growth,Yield, And Quality Of Strawberry, Masoud Haghshenas, Sander H. Van Delden, Mohammad Javad Nazarideljou

Turkish Journal of Agriculture and Forestry

Strawberry (Fragaria × ananassa Duch) cultivation is not without difficulty since its root environment is sensitive to many biotic and abiotic stresses. In addition, production is often phosphate limited, even at relatively high phosphorus levels, as the high fruit yields greatly exceed the capacity of the phosphorus supply by the root system. Arbuscular mycorrhizal fungi (AMF), plant growth promoting bacteria (PGPB), and combinations of both are known to mitigate stress and enhance nutrient uptake, particularly phosphorus. Therefore, we studied the effects of AMF (Glomus mosseae, and Glomus intraradices), PGPB (Azospirillum lipoferum DSM1691, and Pseudomonas fluorescens DSM 50090), and their combinations …

Violent Conflict Drives World Hunger And Food Insecurity, E. Wesley F. Peterson

Cornhusker Economics

The World Food Program (WFP) with support from the United States and other countries works to provide food to those in need as a result of conflict, adverse climate effects, poverty, and government mismanagement. It is limited in what it can do, however, by budget constraints and rising food prices. On top of the financial issues, the delivery of food assistance is particularly complicated in areas of conflict where warring adversaries often hijack food supplies intended for the other side. While it is illegal under International Humanitarian Law to use starvation as a weapon of war, Dzerowicz (2023) has identified …
