The need to continuously multiply new improved seeds for onward delivery to the farmers, with the sole aim of attaining food self-suffi ciency, necessitates this study. Data were collected from 17 maize and soybean out growers randomly selected from a list of out growers provided by the seed manager, using structured questionnaire. The data were analyzed using percentages and gross margin analy...
Larger, and deeper, root systems of new maize varieties, compared to older varieties, are thought to have enabled improved acquisition of soil resources and, consequently, greater grain yields. To compare the spatial distributions of the root systems of new and old maize varieties and their relationships with spatial variations in soil concentrations of available nitrogen (N), phosphorus (P) an...
Maize is a major cereal crop and an important model system for basic biological research. Knowledge gained from maize research can also be used to genetically improve its grass relatives such as sorghum, wheat, and rice. The primary objective of the Maize Genome Sequencing Consortium (MGSC) was to generate a reference genome sequence that was integrated with both the physical and genetic maps. ...
The food supply is being increasingly challenged by climate change and water scarcity. However, incremental changes in traditional cropping systems have achieved only limited success in meeting these multiple challenges. In this study, we applied a systematic approach, using model simulation and data from two groups of field studies conducted in the North China Plain, to develop a new cropping ...
The objective of this study was to investigate the nutritive value, in vitro dry matter degradability (IVDMD), and ensiling characteristics legume foliage–maize straw silages. For silage, proportion maize 20%:80% (maize–lablab (ML), maize–indigenous cowpea (MI), maize–Betswit (MB), maize–Dr Saunders (MD)). Maize alone (M) used as a control, making up five treatments. Silages were opened after 4...
We tested the hypothesis that reduced root cortical cell file number (CCFN) would improve drought tolerance in maize (Zea mays) by reducing the metabolic costs of soil exploration. Maize genotypes with contrasting CCFN were grown under well-watered and water-stressed conditions in greenhouse mesocosms and in the field in the United States and Malawi. CCFN ranged from six to 19 among maize genot...
Quality Protein Maize is an improved variety of maize which contains higher amount of lysine and tryptophan. Cowpea is an indigenous legume widely consumed in Nigeria. Quality Protein Maize was malted by steeping, germinating, drying and milling while cowpea was dehulled, steamed, dried and milled. The resulting flours were blended to produce complementary food at ratios of 100:0; 70:30 (Qualit...
Maize Agrobacterium-mediated transformation efficiency has been greatly improved in recent years. Antioxidants, such as, cysteine, can significantly improve maize transformation frequency through improving the Agrobacterium infection efficiency. However, the mechanism underlying the transformation improvement after cysteine exposure has not been elucidated. In this study, we showed that the add...
