Yield improvement in maize for tolerance to low soil nitrogen

Autor: Ajala, S. Olaniyan, A.B. Olayiwola, M.O. Job, A.O.

Low soil nitrogen limits maize (Zea mays L.) production in the West and Central African subregion. Levels of residual genetic variability were determined in two low‐N populations using selfed progeny evaluations, and results obtained indicate large genotypic and phenotypic variances for grain yie...

Performance of tropical early maturing maize cultivars in multiple stress environments

Autor: Badu-Apraku, B. Menkir, A. Ajala, S. Akinwale, R. Oyekunle, M. Obeng-Antwi, K.

Maize (Zea mays L.) production in west Africa (WA) is constrained by drought, Striga hermonthica infestation and low soil nitrogen (N). Maize varieties resistant to Striga, drought, and low N are ideal for WA, but genotype × environment interaction on these traits are usually significant due to d...

Input use and profitability of arable crops production in Nigeria

Autor: Awotide, D.O. Ikudaisi, O.J. Ajala, S. Kaltungo, J.H.

The study accessed the profitability of the usage of all input in crop production through Community-Based Agricultural and Rural Development Project (CBARDP) among rural dwellers in the Northern part of the country with the view of comparing the input usage to recommended practices. The study was...

Selection of maize genotypes resistant to pink stem borer and sugarcane borer.

Autor: Ngwuta, A. Ajala, S. Obi, I.U. Ene-Obong, E.E.

Maize is an important economic crop grown in Nigeria. Its production is dramatically affect by the pink stem borer—Sesamia calamistis (Hampson, Noctuidae) and sugarcane borer—Eldana saccharina (Walker, Pyralidae) that are endemic in Southeastern Nigeria. In areas of stress, existing genotypes may...

Effects of NPK single fertilizers on relative growth performances of two cycles of maize (Zea mays L.) grown in a degraded soil of Southwest Nigeria

Autor: Chukwuka, K. Ajala, S. Nwosu, P.C. Omotayo, O.E. Chukwuka, K.

The balanced use of inorganic amendments to enhance effective crop production for developing world economies like Nigeria is paramount to achieve her Millennium Development Goals (MDGs) for its teeming population. Thus this study was carried out to assess the relative growth performances of a maj...

Expected responses to aggregate trait selection in maize (Zea mays L.)

Autor: Ajala, S.

This study was conducted with the objective of predicting and comparing expected gains for two selection indices and to aid identification of a better index to improve maize populations for a target environment, in thiscase, small-farm conditions. Data from S2 lines from each of three populations...
