Local species‐specific effect of trees and shrubs on the incidence of the millet head miner, Heliocheilus albipunctella (Lepidoptera, Noctuidae)

open access: yesAgricultural and Forest Entomology, Volume 28, Issue 1, Page 38-48, February 2026.
Abstract Understanding the interactions between crop pests, natural enemies and semi‐natural habitats in agricultural landscapes is crucial for developing ecology‐based pest management in agroecosystems. In the present study, we investigated the local‐scale species‐specific effect of tree and shrub cover and diversity on the incidence and natural pest ...

BF2 Complexes of N‐arylated 1‐amino‐anthraquinone, ‐xanthone, ‐thioxanthone, and Related Compounds: Synthesis and Properties

open access: yesEuropean Journal of Organic Chemistry, Volume 29, Issue 2, January 16, 2026.
Syntheses of BF2 complexes of 1‐(arylamino)anthraquinones and related compounds are developed and their properties studied. The physical properties of anthraquinones can be modulated by the introduction of arylamino groups next to the carbonyl function.

Influence of notillage on carbon sequestration and erosion in Brazil [PDF]

open access: yes, 2004
Les sols constituent le plus gros réservoir superficiel de C (hors les roches carbonatées), environ 1500 Gt C, ce qui équivaut à presque trois fois la quantité stockée dans la biomasse terrestre, et deux fois celle de l'atmosphère.

Agronomic Performance and Water Use Indicators of Cactus Species Widely Cultivated in Semiarid Regions

open access: yesIrrigation and Drainage, Volume 74, Issue 5, Page 2156-2173, December 2025.
ABSTRACT This study aimed to evaluate the agronomic performance, crop evapotranspiration (ETc), crop coefficients (Kc, Kcb and Ke) and yield response factor (Ky) of three forage cactus clones—Orelha de Elefante Mexicana (OEM), Miúda (MIU) and IPA Sertânia (IPA)—grown in a semiarid environment.

Le volume d’herbe disponible par vache : un indicateur synthétique pour évaluer et conduire un pâturage tournant

open access: yesINRAE Productions Animales, 2000
Gérer un système de pâturage nécessite de définir de manière cohérente trois types de règles. Les règles de planification s’appuient le plus souvent sur des référentiels régionaux (chargement par saison en fonction des apports d’azote).

Differences in the Morphological Characteristics of the Land Races of the Soft and Emmer Wheat in Relation to the Modern Varieties [PDF]

open access: yes, 2009
For the organic farmers there is important question which varieties of wheat are right for organic farming in Less Favoured Areas. Modern varieties of wheat are bred in the conditions of conventional (high imput) farming.
