“…Therefore, it is essential to determine the optimal combination of maize varieties and Nfertilizer application rates that will result improved yields in different agroecologies. Several studies have shown significant responses of maize varieties to N-fertilizers (Kamara et al, 2009;Garba et al, 2017;Ewansiha et al, 2020). However, a study by Ewansiha et al (2019) reported that late maturing maize varieties had higher grain yield than early maturing maize varieties in the rainforest agroecology of Nigeria.…”

The agronomic response of maize (Zea mays L.) to nitrogen (N) fertilizer depends on the cultivation conditions. However, there is a knowledge gap on the optimal rates of N fertilizer application for cultivars with different days to maturities in the tropical rainforest agroecology. Field trials were conducted at the Teaching and Research Farm, University of Benin, Benin City, which lies in the tropical rainforest of Nigeria in 2019 and 2020, to evaluate the agronomic performance of maize of contrasting maturities at varying rates of nitrogen fertilizer application. The experiment was arranged in a split-plot fitted into a randomized complete block design having three replications. The main plot treatment was N rate (0, 30, 60, 90 and 120 kg N ha–1) and sub plot treatment was maize variety (extra-early maturing (TZEE-Y POP STR C4); early maturing (2008 DTMA-Y STR); intermediate maturing (BR. 9928 DWRSR) and late maturing (TZL COMP.4 C4). Results showed non-significant N rate × variety interactions for measured traits except 1000-seed weight. However, optimum grain yield was achieved at 60 kg N ha–1 beyond which rate, additional N did not cause any significant increase, suggesting that application of N above this optimum rate to maize plants may result in fertilizer wastage. The intermediate and late maturing varieties out-yielded the extra-early and early maturing varieties, indicating better utilization of available N. Therefore, in the rainforest agro-ecology, intermediate and late maturing maize varieties should be grown at 60 kg N ha–1 for optimum yield.

“…These researchers stated that tolerant maize hybrids and open-pollinated cultivars have been developed with moderate levels of resistance and reduced numbers of emerging Striga plants. Moreover, from an experimental research conducted in the Southern Guinea Savannah, it was reported that a resistance maize variety performed remarkably better than the local variety under Striga infested fields (Garba, Yakubu, Gwandu, & Muhammad, 2014).…”

The study was conducted in Lapai, Niger State, North central Nigeria to determine the profitability of improved maize variety (SAMMAZ 17) in cooperative farmer's fields. Demonstration plots were cited in three cooperative farms where the improved variety and a local variety were planted. All agronomic practices were carried out uniformly and simultaneously on the plots. In addition, structured questionnaires were administered to 20 members of each of the cooperative farms. Participants were selected by means of simple random sampling techniques to solicit information on the performance of SAMMAZ 17 maize variety on their farms. Descriptive statistics were used to analyse the socioeconomic characteristics of the farmers, while gross margin analysis was used to compare the profitability of maize varieties. The results revealed that maize farmers were mostly male and small-scale in operations. The local maize variety supported high Striga infestation with low yield of 1.7 t/ha, while SAMMAZ 17 yield was 4.4 t/ha under less Striga infestation. The gross margin production of SAMMAZ 17 maize variety was N 254,127.40, while the gross margin for the production of farmer's maize variety was N 102,517.90. Based on these findings, SAMMAZ 17 was found to be profitable and is therefore recommended for planting in Striga endemic fields in North Central Nigeria.
