Meta-analysis of the effects of Rhizobia inoculants and phosphorus fertilizer on soybean nodulation in Africa

Soybean has the potential to bring significant benefits in diversified cropping systems, which could help restructuring soil fertility and allow smallholders to increase grain yield. Rhizobium inoculation improves the biological nitrogen fixation (BNF) in legume crops and assists resource-poor farmers to increase grain yield at lower financial costs. The efficacy of symbiotic bacteria on legumes can also be...

Classifying highland quality protein maize in bred lines into heterotic groups

Efforts to boost maize productivity can be undertaken through systematic management of heterosis. Combining ability test is a critical step towards identifying a heterotic group of new parental lines. Different heterotic grouping methods has been used by different researchers. Among these, SCA and hybrid mean, hybrid index, combined use of amplified fragment length polymorphism (AFLP), SSR markers and heterotic...

Combining ability of quality protein maize inbred lines under low and optimum soil nitrogen environments in Ethiopia

Maize (Zea mays L.) is the most important cereal crop on which many smallholder farmers in sub-Sahara Africa (SSA) depend on as a sole source of calories, proteins, and vitamins. However, conventional maize is deficient in two essential amino acids, lysine, and tryptophan. Thereafter, Quality Protein Maize (QPM) developed to combat protein malnutrition. In SSA low soil nitrogen is also the most limiting factor in maize...

Correlation and path coefficient analysis studies in Ethiopian Mustard (Brassica carinata A. Braun)

Ethiopia is the center of origin for Ethiopian mustard (Brassica carinata). The crop is one of the oldest oil crops and farmers in the highlands of the country grow as a leafy vegetable in their gardens. However, no attempt has been made to assess the association of characters and path analysis in Ethiopian mustard leaf. This study was conducted to assess association of traits among leafy vegetable yield and yield...
