Genetic Variability and Inter-relatedness of Agronomic Traits of Single Cross Hybrid Maize in Contrasting Soil Nitrogen-nutritional Conditions

Autor: D.K. Ojo, S. A. Olakojo, D. J. Ogunniyan

Publikováno v: International Journal of Plant & Soil Science. :1-15

Background: Lowering the nitrogen demand is the most cost effective and sustainable option to increase grain yield of maize in poor fertility soil. Aim: This study was conducted to estimate the variability and inter-traits’ association of white and

Low soil nitrogen (low-N) and stem borer attack are two of the major stresses limiting maize production in West and Central Africa (WCA). Thus, there is need to intensify efforts aimed at identifying inbred lines with resistance and tolerance to thes

Differential grain yield performance of single cross hybrid maize in varied nitrogen conditions

Autor: D.K. Ojo, O.A. Omikunle, S. A. Olakojo, D. J. Ogunniyan, S.A. Makinde

Publikováno v: African Crop Science Journal; Vol 27, No 3 (2019); 445-461

Presence of genotypic differences in maize ( Zea mays L.) grain yield in multi-environments would help plant breeders to make logical decisions in improvement programmes of the crop. Hence, the grain yield performance, heterosis and stability in hybr
