Pearl millet is potentially prone to diseases as such downy mildew caused by Sclerospora graminicola causing losses in grain yield. Crop improvement technologies such as seed priming and fertilizer micro-dosing have only been applied to improve crop production without assessing their implications in the diseases of crops. This study examines the effects of these technologies on downy mildew of pearl millet. An... Read more.

Maize is one of the most important crops grown by smallholder farmers in Amatole and O.R. Tambo Districts of the Eastern Cape Province. Improved open pollinated varieties of maize have been shown by studies to be relatively drought tolerant as compared to hybrids, and can be a valuable step if adopted and used by smallholder farmers. This study assessed the factors that influence the demand for improved maize OPVs in... Read more.

Fonio (Digitaria spp.) is a highly nutritious, health promoting and cheaply available cereal which is, however, marginalized in many parts of Nigeria, and research attention on the crop is yet to measure up to its usefulness as a dietary staple. In this study therefore, five accessions each of two common species (Digitaria exilis and Digitaria iburua) were assessed for intra and inter- species variation in antioxidant... Read more.

More than half of the world’s population, especially women and children in the developing countries suffer from micronutrient malnutrition especially deficiency in iron and zinc. Micronutrient malnutrition problems increased the interest of researchers to increase the mineral contents (Fe and Zn) in cereals to ensure adequate attainment of dietary minerals. A lot of variability does exist for micronutrients (Fe,... Read more.

Viability and vigour are seed quality parameters that affect the seed chain. Seed vigour is a measure of accumulated damage in seed as viability declines from physiological maturity. This study aimed at determining the seed vigour of various sorghum genotypes stored ex situ for 10 years using the Heat Shock Stress Test (HSST), Cold Test (CT), Standard Germination Test (SGT) and field germination. The samples from the... Read more.

Lodging is characterized by the reduction in plant canopy and the bending or fall over of mature plants with panicles on the soil or water resulting in yield and quality decline. It may be induced by variations in crop nutrition, water management, susceptible tall varieties and windy conditions. In all cases the plant stem base is unusually weak with a reduced diameter. This study evaluated the use of 2 plant... Read more.
