Hunting and gathering remained the main mode of subsistence of humanity for hundreds of thousands of years, beginning some 1.8 million years ago, and until the Neolithic Revolution (some 10,000 years ago), when agricultu...

Los cítricos son uno de los cultivos frutales más extendidos a nivel mundial. Constituyen un grupo muy complejo de genotipos con una gran diversidad fenotípica. Originarios del sudeste asiático, los ancestros más an...

Abstract Among oilseeds crops, Brassica napus L., is of great importance globally. The economic yield and harvest efficiency are significantly limited by seed shattering, which represents a persistent agronomic constrain...

Abstract Plant tolerance, a significant parameter against saline conditions has become challenging and a hallmark for agriculture crops. There is an urgent need to incorporate green nanostructure approaches to cope with ...

Potato cyst nematodes, G. rostochiensis and G. pallida, are the most economically important nematode pests of potatoes worldwide and are subject to strict quarantine regulations in many countries. Globodera ellingtonae w...

Peri-urban horticulture is crucial to local populations, but a global paucity of information exists regarding the contamination of the associated waterways because of this activity. The aim of this study was to assess pe...

The nitrogen-fixing symbiosis between leguminous plants and soil bacteria, collectively termed rhizobia, is a major contributor of fixed nitrogen to the biosphere. The ability of legumes to secure nitrogen from the atmos...

ABSTRACT The objectives of this study were to evaluate the effects of cultivation and hay making factors on chemical composition, protein fractionation, and digestibility in rice straw, as well as to identify the chemica...

In China, schistosomiasis is targeted for elimination. As the country approaches elimination, it is critical to evaluate how the dynamics of transmission are changing in remaining pockets of disease. We have been studyin...

Line breeding programs of autogamous crops like barley and wheat are characterized by multiple crosses with high variability in cross means and segregation variances. From theory of order statistics, we derived formulas ...

Biotic and abiotic stresses reduce crop yields, yet existing image‑based diagnostic models are often crop‑specific, computationally intensive, and poorly interpretable. This study present: (i) a multi-crop diagnostic...

Tomato (Solanum lycopersicum L.) crops are affected by a diversity of pests. Among these pests, the whitefly Trialeurodes vaporariorum (Westwood) (Hemiptera: Aleyrodidae) and the leaf miner, Tuta absoluta (Meyrick) (Lepi...

The tomato leafminer Tuta absoluta (Meyrick 1917) (Lepidoptera:Gelechiidae) is a devastating pest, causing losses of up to 100%. An interesting tool for its control is the use of the insect specific viruses of Baculovir...

Abstract Major concerns in view of global issues including population increase, climate change, food insecurity and declining cultivable land are ones of expansion. Ensuring nutritional security and helping to mitigate t...

Abstract Hydrothermal carbonization (HTC) transforms wet or dry biomass into hydrochar, generating a nutrient-rich process water, hereafter termed HTC-PW, which is often overlooked as waste. This review synthesizes curre...

Um experimento foi realizado com o objetivo de avaliar a produção e extração de nutrientes de diferentes forrageiras. Foram implantadas quatro culturas anuais: milho, sorgo-sudão, sorgo forrageiro e girassol em um d...

En este artículo se presentan resultados de una investigación antropológica sobre el cáncer entre docentes rurales expuestas ocupacionalmente a agroquímicos. El estudio se desarrolló en la zona sudeste de la provin...

Disease Diagnosis in crops is a very expensive and lengthy process, as it often involves the need for few experts to make observations, leading to delayed diagnosis, viral spread of diseases, and thus, massive economic l...

Brassica oilseeds are important protein crops for Nordic agriculture. Oilseed production is challenged by multiple insect pests, most importantly the pollen beetle (Brassicogethes aeneus). Concerns about pyrethroid resis...

O experimento foi conduzido para avaliar o rendimento e valor nutritivo da forragem precoce, da silagem e dos grãos do rebrote de 14 genótipos de seis espécies de cereais de inverno. O experimento foi em blocos ao aca...

A hibridação interespecífica entre o caiaué (Elaeis oleífera (Kunth) Cortés) e o dendezeiro (E. guineensis Jacq.) tem sido explorada com o objetivo de desenvolver cultivares tão produtivas quanto as de dendezeiro,...

Abstract The premix formulation of fluopyram and trifloxystrobin is a broad-spectrum fungicidal combination that is widely used to manage foliar diseases in vegetable crops. However, concerns regarding its persistence an...

Flavonoids are polyphenolic compounds and color most flowers, fruits and seeds. The regulation of flavonoid biosynthetic genes is directed by ternary complexes composed of MYB-bHLH-WD40 transcription factors. DNA-binding...

The constant use of sodium N-methyldithiocarbamate (metam sodium: MS) in protected agriculture in México has attracted the attention of researchers and producers on their effects on the environment. The objective of thi...
