The Complexity of Multidimensional Learning in Agriculture

Econometrica, Volume 94, Issue 2, Page 465-503, March 2026.
Studies on agricultural technology adoption often focus on one input, practice, or package, which is analytically useful, but may overlook the complexities involved with multidimensional learning needed for a lot of agricultural decisions. In Kenya, we study farmers' dynamic learning (from oneself and others) and adoption decisions over six seasons ...

Genetic Diversity and Inter-Trait Relationships among Maize Inbreds Containing Genes from Zea diploperennis and Hybrid Performance under Contrasting Environments

Agronomy, 2020
Accurate estimation of genetic variability present in tropical maize inbreds with varying reactions to Strigahermonthica infestation is essential for efficient and sustainable utilization to ensure increased genetic gain in a breeding program. Thirty-six

Striga Management through Herbicide Resistance: A Public-Private Partnership in Action [PDF]

Striga is an indigenous parasitic weed that attacks cereals and other crops in Africa. In maize croplands alone, Striga infests over 2.3 million ha resulting in 1.6 million tons of grain loss worth US $383 million annually.

A new species of Drimia Jacq. ex Willd. (Asparagaceae) from Nellai wildlife sanctuary, Western Ghats, India

Nordic Journal of Botany, Volume 2026, Issue 2, February 2026.
The new species Drimia courtallensis from the Nellai Wildlife Sanctuary of Tamil Nadu, India is described and illustrated. It is similar to Drimia razii,in its necked bulb, hysteranthous nature, lax inflorescence and diurnal flowers on moderately short pedicels but it can be distinguished by its broader linear‐lanceolate leaves (230–420 × 6–15 mm ...

Identification of QTLs Controlling Resistance/Tolerance to Striga hermonthica in an Extra-Early Maturing Yellow Maize Population

Agronomy, 2020
Striga hermonthica parasitism is a major constraint to maize production in sub-Saharan Africa with yield losses reaching 100% under severe infestation. The application of marker-assisted selection is highly promising for accelerating breeding for Striga ...

Determining smallholder farmers’ preferences for Push-Pull technology dissemination pathways in western Kenya [PDF]

The push-pull technology (PPT) has widely been disseminated to control stemborer (Chilo partellus and Busseola fusca) and Striga weeds (Striga hermonthica and Striga asiatica) in maize fields in Kenya. This study examined farmers’ preferences for various

Striga parasitizes transgenic hairy roots of Zea mays and provides a tool for studying plant-plant interactions [PDF]

, 2012
Background Striga species are noxious root hemi-parasitic weeds that debilitate cereal production in sub-Saharan Africa (SSA). Control options for Striga are limited and developing Striga resistant crop germplasm is regarded as the best and most ...

Increasing the diversity of Sycorax Haliday, 1839 (Diptera: Psychodidae) in the Neotropical region: New species from the Brazilian Atlantic Forest

Austral Entomology, Volume 65, Issue 1, February 2026.
Abstract Four new species of Sycorax Haliday, 1839 are described: Sycorax alumna sp. nov., Sycorax catarina sp. nov., Sycorax paranaensis sp. nov., and Sycorax striga sp. nov., with the females of Sycorax striga sp. nov. bearing characteristics that suggest haematophagous behaviour.
