Striga gesnerioides (Willd) Vatke, is a major destructive parasitic weed of cowpea (Vigna unguiculata (L.) Walp.) which causes substantial yield reduction in West and Central Africa. The presence of different virulent races within the parasite population contributes to significant genotype × envi...

Phenotypic diversity for agronomic characteristics was determined in an experiment without fertilizer in 1998 in 41 two-row and 21 six-row winter barley accessions, provided by the Nordic Gene Bank, at Højbakkegård (Denmark). There were significant differences among these 62 accessions for spring...

Variation in agronomic and quality characteristics was investigated in 220 Nordic spring barley cultivars across distinct environments (6 locations during 3 years) in the Nordic Region of Europe. The objectives of this research were to determine the importance of the genotype by environment inter...

Electronic insect-feeding monitors are increasingly being used to study the feeding behavior of piercing-sucking insects in relation to host resistance and biotypes. The original AC design has been modified several times to simplify and expand the signal generator and signal processor. We report ...

Various factors influencing the adoption of weed control technologies in Abia State were studied. A multi-stage random sampling procedure was used to select 510 cassava farmers in 2006. Results showed that 56.5% of the respondents were females, that are largely (90.2%) in their productive years. ...

Deforestation and degradation are tied to a complex array of socioeconomic and political factors. Many assume that among the most important of these are the particular bundles of rights regulating who can benefit from land (tenure form) and the overall assurance that those rights will be upheld (...

A long history of household-level research has provided important local-level insights into climate adaptation strategies in the agricultural sector. It remains unclear to what extent these strategies are generalizable or vary across regions. In this study we ask about three potential key factors...
