Genetic gains from selection for high grain yield and Striga resistance in early maturing maize cultivars of three breeding periods under Striga-infested and Striga-free environments

Field Crops Research, 2013
Abstract Maize is the most important staple cereal crop in sub-Saharan Africa (SSA) and has great potential to rectify the food insecurity in the sub-region. A study was conducted at four locations two each in Nigeria and Benin in 2010 and 2011 to determine the rate of genetic improvement in the grain yield of 50 maize cultivars developed during ...

Fertiliser Microdosing and Organic Amendments as an Integrated Soil Fertility Management Strategy: Evidence From On‐Farm Sorghum Trials in Burkina Faso

Soil Use and Management, Volume 42, Issue 1, January‐March 2026.
ABSTRACT Fertiliser microdosing (FM) is widely promoted in sub‐Saharan Africa as a means to improve fertiliser use efficiency in cereal crops. However, combining organic amendments with FM could further increase the agronomic efficiency of the latter because of possible synergies between both practices.

Strip Crops and Intercrops Outperform Crop Rotations for Weed Management Under Conservation Agriculture in Zimbabwe

Weed Research, Volume 66, Issue 1, January/February 2026.
ABSTRACT High weed infestation remains a major constraint on crop productivity for smallholder farmers practising Conservation Agriculture (CA). Fewer, more diverse weeds are desirable to reduce competition and provide ecosystem services. Crop diversification can help, but it is not yet clear which species combinations and layouts are most effective ...

CRISPR/Cas9-mediated mutagenesis of CAROTENOID CLEAVAGE DIOXYGENASE 8 in tomato provides resistance against the parasitic weed Phelipanche aegyptiaca. [PDF]

, 2019
Broomrapes (Phelipanche aegyptiaca and Orobanche spp.) are obligate plant parasites that cause extreme damage to crop plants. The parasite seeds have strict requirements for germination, involving preconditioning and exposure to specific chemicals ...

Assessing Agronomic Practices and Constraints of Pearl Millet (Pennisetum glaucum [L.] R. Br.) Production in Semiarid Areas of the West Hararghe Zone, Eastern Ethiopia

International Journal of Agronomy, Volume 2026, Issue 1, 2026.
Pearl millet is widely regarded as one of the most promising cereal crops for food and nutritional security in semiarid regions globally. However, it has long been considered an orphan crop due to limited attention from the scientific community and policymakers, as well as low public awareness of its potential role within the food system. Consequently,

Phenotypic evaluation of gene-pyramided cowpea lines for resistance to Striga gesnerioides using multi-origin inoculum from Nigeria

Discover Agriculture
Cowpea (Vigna unguiculata (L.) Walp.) is a major source of dietary protein in sub-Saharan Africa, but its productivity is severely constrained by the parasitic weed Striga gesnerioides. This study evaluated 140 BC3F2 cowpea lines developed through marker-

Screening of Tobacco Genotypes for Tolerance/Resistance to Striga gesnerioides infestation in Zimbabwe

Advances in Crop Science and Technology, 2018
Witch weed (Striga gesnerioides) is a root parasitic weed of tobacco and cowpea in Sub- Saharan Africa. It is very difficult to control and host plant resistance is the most promising effective method affordable to small-scale farmers. This study was done to screen local tobacco genotypes for tolerance and resistance to Striga gesnerioides infection ...

Boosting Drought Resilience in Rice: The Priming Effects of Zaxinone and Its Mimics

Physiologia Plantarum, Volume 177, Issue 6, November/December 2025.
ABSTRACT Climate change increasingly threatens global agriculture, with drought emerging as a major constraint on crop productivity. Plants activate complex adaptive responses, involving genetic, physiological, and hormonal networks, to cope with water deficit.

Maize production constraints, traits preference and current Striga control options in western Tanzania: farmers’ consultation and implications for breeding

Acta Agriculturae Scandinavica. Section B, Soil and Plant Science, 2019
Striga spp. severely affect maize yields in Tanzania causing yield losses varying from 20% to 100%. The use of Striga resistant varieties is an economical and environmentally friendly option that can be easily adopted by smallholder farmers.
