Detection of Tobacco mosaic tobamovirus resistance gene (N-gene) in tobacco genotypes using gene specific markers.
(University of Zimbabwe, 2012-11-01)
Tobacco mosaic tobamovirus (TMV) is one of the most destructive viral diseases that
threaten worldwide tobacco production. Use of host resistance appears to be the best way to
control the disease. The use of specific ...
Participatory Variety Selection and Evaluation of Sixteen Sorghum [Sorghum bicolor (L) Moench] Varieties Grown on the Flat and on Tied Ridges
(2012-08-29)
Sorghum [Sorghum bicolor (L.) Moench] is a crop of great diversity, mainly grown in semi-arid and arid areas because of its adaptability to moisture stress and low fertility. In Zimbabwe, sorghum production is affected by ...
Effects of cotton-cowpea intercropping on crop yields and soil nutrient status under Zimbabwean rain-fed conditions
(2012-09-03)
Intercropping of cotton and cowpea is one of the ways to improve food security and soil fertility while generating and maintaining cash income of the rural poor. A study was carried out to find out the effects of cotton-cowpea ...
Evaluation of Draught Animal Power Systems for Maize and Cotton Production at Smallholder-Farmer Level in Masvingo Province.
(2012-08-30)
An evaluation of smallholder draught animal power systems was conducted in six study areas in Masvingo and Chivi districts of Masvingo province over two seasons 1999-2000 and 2000-2002. The objective was to investigate the ...
Evaluation of the feed resources and analysis of body condition scores of local pigs in a semi-arid smallholder farming area of Zimbabwe
(2012-07-11)
The objectives of this study were to characterise the types, seasonal distribution, and nutritive value of feed resources and growth performance of local pigs in Chinyuni ward,Chirumanzu district. Pig herd sizes were (mean ...
Genotype X Environment Interaction Effects on the Developmental Time, Kernel Modification and Yield of Experimental Quality Protein Maize (Zea mays L.) hybrid Varieties
(2012-08-30)
Genotype „e environment interactions occur in crops grown in more than one environment such that it is unusual for a single genotype to perform better than other genotypes at all the locations in which they are grown posing ...
Genetic variability, host specificity and resistance in Striga Asiatica-host plant interactions
(2012-08-30)
Genetic analyses were conducted on Striga asiatica populations collected from different host species and geographic areas throughout Zimbabwe. These collections had been suspected to differ in their virulence, leading to ...
Evaluating Hybrid-Maize Simulation Model for Grain Yield Estimation in Hybrid Seed Maize Production
(2012-08-30)
The study was carried out to determine the effect of Male Planting Date (MPD) and Female Plant Population (FPP) on the Grain Yield (GY), yield components and flowering of a three-way hybrid. The study also evaluated ...
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 ...
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 ...
