Withania somnifera is an important aromatic medicinal plant and possesses wide array of pharmacological properties. In the present investigation, an improved version of hairy root culture system was developed by optimizing various transformation parameters such as type of explant, concentration of acetosyringone, Agrobacterium types and co-cultivation period. Between the leaf and cotyledon explants and two Agrobacterium rhizgenes strains (R1000 and... Read more

Intermittent leaching of copper from copper based fungicide through a saturated soil profile

Journal of Soil Science and Environmental Management

J. Soil Sci. Environ. Manage.

Copper is a micronutrient required for plant growth. However, it can have negative effect on plant growth if the concentration is too high. The aim of this study was to examine copper concentrations of leachate from soil columns treated with copper based fungicide. A 2 × 4 factorial arrangements consisting of two soil types (0 to 60 cm sample depth) and four rates of copper based fungicide concentrations (0, 1.88, 3.75 and 7.50 g/L ) was used... Read more

African Journal of Agricultural Research

Afr. J. Agric. Res.

The government of Swaziland has fully recognized the role of smallholder irrigation development in poverty reduction hence intensive investments have been made to empower rural smallholder farmers through irrigation. The Lower Usuthu Irrigation Project (LUSIP) is one of the projects which strive to empower 2600 rural poor households to attain an improved quality of life and be able to sustain it. The study sought to interrogate the development model... Read more
