Autor: Julius Oluseyi Olasoji, Johnson Adedayo Adetumbi, Solomon A. Makinde, D. J. Ogunniyan

Publikováno v: Journal of Agricultural Sciences (Belgrade), Vol 66, Iss 2, Pp 105-119 (2021)

Breeding for yield and quality requires the assessment of the seed metrics and vigour traits. This study, therefore, assessed the variability and inter-dependence of grain yield (GY), seed morphometric and vigour traits in hybrid maize. Seeds of 75 e

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

Diallel analysis of maize inbred lines for agronomic traits in nitrogen stress and optimal conditions

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

Publikováno v: Ghana Journal of Agricultural Science; Vol 54, No 1 (2019); 10-23

Increasing demand, soil cultivation pressure and adverse climate change effects necessitated maize production in nitrogen stress soils. This study examined the general combining ability (GCA) of 12 maize inbreds and specific combining ability of thei

Response of groundnut (Arachis hypogaea L.) genotypes to accelerated ageing treatment

Autor: D. J. Ogunniyan, M. A. Adebisi, Johnson Adedayo Adetumbi, Kehinde O.S. Aderiye, T. O. Kehinde

Publikováno v: Notulae Scientia Biologicae, Vol 13, Iss 1 (2021)

Reduction in germination of crop seeds due to depletion of food reserves and decline in synthetic activity due to ageing has become a serious concern to groundnut growers who need adequate, high quality seeds to sustain groundnut production. Therefor

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
