Genetic Variation for Seedling Traits in Hydroponics and Correlated Response with Mature Plant Traits on Acid Soil Field

G. O. S. Ojo, L. L. Bello & S. A. Ayuba · International Journal of Plant & Soil Science · 2016

Four levels of aluminium activity (0, 5, 50 and 300 μMAl3+) were used to screen soybean seedlings in hydroponics for 3 days (3D) and 13 days (13D). The objective of the research was to determine genetic variation for aluminium stress tolerance in seedlings (primary root length, r...

Combining Ability and Heterosis for Some Yield Component Traits in a 10x10 Diallel Cross of Rice (Oryza sativa L.)

T. Vange, G. O. S. Ojo & A. M. Ladan · Asian Journal of Research in Crop Science · 2020

A ten – parent diallel experiment was carried out at the Teaching and Research Farms of the Federal University of Agriculture, Makurdi, Nigeria, to estimate combining ability and heterosis in rice. The design was a 10x10 alpha lattice with three replications and data was collecte...

Effect of Organic Manure and Harvesting Age on Morphological Parameters, Yield and Physical Silage Quality of Brachiaria ruziziensis

F. A. Opawoye, T. T. Ikyume & G. O. S. Ojo · Asian Journal of Research in Agriculture and Forestry · 2026

Forage productivity and quality in ruminant nutrition depend on factors such as organic manure application and harvesting age, necessitating evaluation of their combined effects on Brachiaria ruziziensis yield and morphology.The aim of this study was to evaluate the impact of dif...
