Effect of reduced feeding allowances on the nitrogen retention and growth of indigenous pigs
The effect of reduced feeding allowances for pigs was investigated in two trials. Trial 1 was aimed at evaluating the effect of graded levels of energy on the nitrogen balance and growth performance of Mukota pigs. Graded ...
Weed management options for cotton-maize systems
Spectral indices: in-season dry mass and yield relationship of flue-cured tobacco under different planting dates and fertiliser levels
(Hindawi Publishing Corporation, 2013-08-13)
This experiment investigated the relationship between tobacco canopy spectral characteristics and tobacco biomass. A completely randomized design, with plantings on the 15th of September, October, November, and December, ...
Manure Management Options for increasing Crop Production in the Small Holder Sector of Zimbabwe.
Cattle manure available to farmers is of low value as a fertilizer N and generally contains less than 1% N, which cannot sustain N requirements for high yielding crops like maize. The purpose of the study was to develop ...
Assesment of Sustainability of Different Populations of Stemborer Species for the Development of Cotesia Flavipes (Hymenoptera: Braconidae) and the Establishment of the Latter in Zimbabwe.
Maize and sorghum are very important crops in Zimbabwe. They are, however, attacked by several pests, among them stemborers. Host suitability studies using Cotesia flavipes Cameron (Hymenoptera: Braconidae) against Chilo ...
Genetic analysis of Maize Streak Virus (MSV) resistance in dwarf maize
Maize Streak Virus (MSV) is the most widespread biotic constraint to maize (Zea mays L.) production in Africa and may lead to total crop loss in susceptible varieties. Use of resistant cultivars is the most efficient and ...
Evaluation and characterisation of twenty-two Soyabean [Glycine max (L) MERRILL] lines under rust infested and non-infested conditions
Soyabean [Glycine Max (L) Merril] is an important leguminous crop, mainly used for human nutrition and livestock feed, as well as improving soil. The major constraint or threat to soyabean production is soyabean rust, a ...
Temporal and Spatial Variability of the Hydrology of Semi-Arid Zimbabwe and its Implications on Surface Water Resources.
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 ...
EXPLORING THE EFFECTIVENESS OF DIFFERENT FERTILIZER FORMULATIONS IN ALLEVIATING ZINC DEFICIENCY IN SMALLHOLDER MAIZE PRODUCTION SYSTEMS IN ZIMBABWE
Fertilization of staple cereal crops in smallholder farming systems of sub-Saharan Africa has mostly focused on supply of nitrogen (N), phosphorus (P) and potassium (K), despite the widespread deficiencies of micronutrients ...
Improving maize (Zea mays L.) growth and yield using Jatropha (Jatropha curcas L.) seed cake under Zimbabwean soil condition
A research study exploring the use of jatropha seed cake as a sole source of nutrients and used in combination with inorganic N fertilizer was conducted on station at Henderson Research Station on sandy and clayey soils ...
