Integrated weed management systems in sorghum based cropping system in Nigeria

Sorghum (Sorghum bicolor (L) Moench) is the fifth most important staple food crop after wheat, rice, maize and barley. Sorghum is consumed by more than 70% of the population. Striga hermonthica is a serious biotic constraint to cereal production in the dry savannas of sub-Saharan Africa. Striga infestation in sorghum is reported to be higher in Nigeria than in other West African countries with about 80% (8.7 million ha)...

Phylogenetic assessment of selected Ghanaian groundnuts, in reference to U.S. mini-core based on Kompetitive allele-specific PCR (KASP) and axiom single nucleotide polymorphism (SNP) array protocols

Groundnut farming has always been an essentially major agricultural venture, both commercially and in subsistence, to the inhabitants of the Northern Regions of Ghana. The current study sought to assess the relationship and genetic diversity, through a phylogenetic analysis, among twenty-five (25) Ghanaian groundnut genotypes, in reference to US groundnut mini-core collection, based on the Kompetitive allele-specific...

The influence of solvent’s polarity on physicochemical properties and oil yield extracted from pumpkin (Cucurbita maxima) seed

The effect of solvent polarity, polar and non-polar solvents, on pumpkin (Cucurbita maxima) seed oil yield and quality based on selected physicochemical properties was investigated. Five different solvents, like petroleum ether, hexane, cyclohexane, acetone and ethanol were used on a laboratory scale in this study. Results showed that both physicochemical properties and oil yield extracted from the pumpkin seed were...

Evaluation in Gampela (Burkina Faso) of agronomic performances of peanut genotypes (Arachis hypogaea L.) selected in Texas

Peanut is of paramount importance in human and animal nutrition, as well as in improving producers’ income. However, its production is faced with abiotic and biotic constraints. Among the biotic constraints, Cercosporiosis diseases are a major handicap in Burkina Faso. In order to minimize the impact of these diseases on peanut yield, important work has been carried out and is still ongoing to select and develop...

Effect of N fortified rice mill waste on soil chemical properties and yield of maize in Nigeria rainforest

Organo-mineral nutrient sources are promising soil amendments for sustainable crop production in Nigeria. A field experiment was conducted at the Teaching and Research Farm of the Cross River University of Technology Obubra during the 2016 cropping season. The objective of the study was to evaluate the effects of nitrogen (N) and amended rice mill waste (RMW) on some soil chemical properties and yield of maize (Zea mays...
