Description:
Maize is an important staple crop in Sub-Saharan Africa due to its diversity in uses and adaptability to various agro-ecological zones. Decline in soil fertility and drought are major constraints to maize production in Benin Republic. Therefore, this study was carried out to evaluate the response of five extra-early maturing maize hybrids and one check (TZEE-W Pop DT STR QPM (which is an open-pollinated variety) to nitrogen fertilizer and naturally-imposed drought at two agro ecologies in Benin Republic. A field experiment was conducted in 2019 growing season at Experimental fields at Komkoma and Angaradebou. The six genotypes were subjected to natural stress as dictated by prevailing weather conditions and two rates of nitrogen: 30 kgN/ha (low N) and 76 kgN/ha (normal N). Treatments without fertilizer application served as control.
