Street theater amplifies need for stress tolerant maize varieties

Posted on Media&Stories, News, News Articles, West Africa News, West Africa Publications, January 7, 2020

The Stress Tolerant Maize in Africa (STMA) project team in Nigeria used street theater to drum up messages on how to mitigate stresses affecting maize production in the country. The messages targeted mainly the youth, informing them that with the right stress-resilient seed varieties and the application of recommended agronomic practices, they can turn farming into a lucrative and livelihood improving enterprise. The messages were developed by the STMA team in collaboration with the Adopted Village Project of the National Agricultural Extension and Research Liaison Services (NAERLS), the Nigerian Forum for Agricultural Advisory Services (NIFAAS) and the Theatre and Performing Arts Department of Ahmadu Bello University, Zaria.

Local artistes in Nigeria perform songs, dance and drama at different markets and streets to create awareness on the benefits of adopting stress resilient maize seed varieties.

Local troupes displayed their skills in song, dance and drama to relay messages on the need for youth to venture into climate-smart agriculture to overcome challenges of drought, current and emerging pests and diseases, as well as improve their yield.

The artistes amplified the benefits of adopting stress resilient maize seed varieties.

Seven such performances were enacted at various markets and streets in Nigeria between August and November 2019. The theme of the street performance was, “Smart people, smart farming”. Since 2017, the STMA team has effectively used this unique campaign method to mobilize communities in rural areas to take adopt stress tolerant maize seed varieties for improved yields and livelihoods.

Association studies between grain yield and agronomic traits of a MARS maize (Zea mays L.) population under drought and non-stress condition

The study aimed at examining the associations between yield and other traits under drought stress and non-stress conditions. A total of 150 MARS testcrosses were evaluated under both conditions at the International Institute of Tropical Agriculture substation for two years under during the dry season. Genotypic and phenotypic correlation, multiple stepwise regression and path co-efficient analyses were carried out to examine the relationship among the traits under both environments. Results showed anthesis-silking interval, days to silking, husk cover and plant aspect were significantly associated with yield under drought condition at both genotypic and phenotypic levels. Yield was positively correlated with plant and ear height but had a negative correlation with plant and ear aspect at both levels under well-watered condition. Regression analysis showed that ears per plant, plant aspect, ear aspect, days to silking, leaf death and plant height had a direct effect on yield, contributing a total of 71.1 % of observed variation under drought, while ears per plant, ear aspect, plant aspect, days to pollen shed, days to silking and plant height contributed about 31.42 % to yield under wellwatered conditions. The study concluded that these traits be used as selection criteria as it will aid improvement of maize yield.
