Mineral Nutrition and Integration of Forage Legumes into Smallholder Farming Systems, with Emphasis on Velvet Bean [Mucuna pruriens (L) DC var. utilis].
(2012-08-30)The major objective of this work was to evaluate and compare forage supply and soil fertility effects of velvet bean (Mucuna pruriens var. utilis) integrated into smallholder cropping systems as ley, intercrop and green ... -
Identification of Fungal Seed Borne Pathogens in Farm Saved and Certified Seed of Sorghum (Sorghum Bicolor (L.) Moench) and Evaluation of the Incidence and Severity of Seed Borne and Non-seed Borne Disease in the Field.
(2012-08-30)A study to identify fungal seed borne pathogens on sorghum seed samples and to assess seed to field transmission of these pathogens was carried out at the Crop Science Department in the 2003/04 season. Seed samples collected ... -
Selection for High Grain Yield and Determination of Heritable Variation in Biomass Yield, Grain Yield and Harvest Index in Different Plant Height Classes of Breeding Populations of Spring Wheat (Triticum Aestivum L.).
(2012-08-30)High grain yield is a prerequisite in the release of wheat genotypes intended for production under high input and capital-intensive cultures such as is practiced in Zimbabwe. Zimbabwe experiences shortages of wheat grain ... -
Temporal and Spatial Variability of the Hydrology of Semi-Arid Zimbabwe and its Implications on Surface Water Resources.
(2012-08-30)There are 170 Communal lands, totaling 163 500 km2 or 42% of Zimbabwe. About 75% of these Communal lands are in Natural regions IV and V that are semi-arid. Water development is therefore a key aspect in ensuring sustainable ... -
