Genetic analysis of gain yield of IITA and CIMMYT earlymaturing maize inbreds under Strigainfested and lowsoil nitrogen environments by Ifie, B.E., Badu-Apraku, Baffour, Gracen, V.E., Danquah, E.Y.

“…Breeding maize (Zea mays L.) hybrids resistant to Striga and tolerant to low soil nitrogen (low-N) will reduce grain yield losses due to stresses in West Africa (WA). Studies were conducted to determine if selection for Striga resistance and/or drought tolerance in early-maturing maize populations improved low-N tolerance in hybrids derived from selected inbreds from International Institute of Tropical Agriculture (IITA) and International Centre for Maize and Wheat Improvement (CIMMYT) under Striga-infested, low-N and optimum environments in Nigeria. …”

Diversity of arbuscular mycorrhizal fungi in Brazil’s Caatinga and experimental agroecosystems by Pontes, J.S., Oehl, F., Marinho, F., Coyne, Danny L., Silva, D.K.A. da, Yano-Melo, A.M., Maia, L.C.

“…Striga hermonthica is a serious parasite of cereals in most of the semi-arid savanna zone of West Africa, causing substantial yield loss. It has been observed that some soybean cultivars are capable of stimulating germination of S. hermonthica seed, which would reduce the seed bank in the soil. …”
