Morpho-physiological variations and yield associated with planting density in soyabean(Glycine max.(L)merrill)
(The University of Zambia, 2017)ABSTRACT Understanding morpho-physiological factors associated with yield decline at high density in soybean (Glycine max L.) can assist in optimizing productivity and seed quality. The objective of this study was to ... -
The efficacy of multiple isolate resistance evaluation for stenocarpella maydis in breeding for ear rot resistance in tropical maize(Zea mays L.)
(The University of Zambia, 2017)Maize ear rots caused by Stenocarpella maydis are among the most important impediments to increased maize production in Zambia. They cause reduction in yield and quality of the maize. The mycotoxins produced by the ... -
Evaluation of the Ceres-maize model in the simulating maize (Zea Mays L)growth, development and yield at different planning dates and nitrogen rates in a subtropical environment of Zambia
(University of Zambia, 2014)Crop simulation models can accurately predict yield with a priori knowledge of the soil properties and crop management practices. Generation of new information through traditional agronomic research practices is not ... -
Breeding for resistance to colletotrichum lindemuthianum (sacc. and Magn. Scrib) in common bean (Phaseolus vulgaris L.)
(University of Zambia, 2016)Bean anthracnose caused by Colletotrichum lindemuthianum causes severe common bean (Phaseolus vulgaris L.) yield losses. Breeding for resistance is the best method to mitigate this problem. The objectives of this study ... -
A multi-criteria ananlysis for mapping soybean (glycine max (l.) Merr. land suitability in Kabwe district of Central Zambia
(University of Zambia, 2016)Land suitability is concerned with the process of estimating the fitness of land for alternative agricultural uses. Land suitability analysis for soybean (Glycine max (L.) Merr.) production culminates into suitability maps ... -
Perceptions and adaptation strategies of fishers to climate variability: A case study of Lake Kariba fishery, Siavionga District
(University of Zambia, 2016)Siavonga district has for the last two decades experienced rainfall that is declining, unpredictable and poorly distributed and increasing temperatures. Climate impact studies on Lake Kariba Kapenta fish stocks show that ... -
Mega-environment identification for soybean [glycline maxl. merrill] in Zambia
(University of Zambia, 2016)Soybean is one of the most important cultivated crops in the world with about 6% of the world’s arable land dedicated to its production. Compared to other major food crops, soybean experienced the highest percentage of ... -
Relationship between environmental temperature and rainfall on beta carotene content and yield in selected sweet potato (Ipomoea batatas (L.) Lam.) varieties
(University of Zambia, 2016)Sweetpotato (Ipomea batatas (L.) Lam) is becoming one of the most important tuber crops in Zambia and ranks second in importance from cassava. Orange fleshed varieties are being introduced to reduce vitamin A deficiency. ... -
Evaluation of maize (Zea mays L.) genotypes with multiple resistance to striga hermonthica (Del.) benth and striga asiatica (L.) kuntze
(University of Zambia, 2016)Striga asiatica is a noxious, obligate hemi-parasite of cereal grasses that causes grain yield losses in susceptible maize genotypes in Southern Africa. The development of host plant resistance is one of the most practical ... -
Morphological and biochemical characterization of soybean nodulating rhizobia indigenous to Zambia
(University of Zambia, 2016)Soybean [Glycine max (L.) Merrill] is known for symbiotic nitrogen fixation by rhizobia present in the soil with which it establishes an efficient symbiosis. In Zambia, current rhizobial inoculants used in soybeans ... -
Assessing the potential of conservation agriculture to off-set the effects of climate change on crop productivity using crop simulations model (APSIM)
(University of Zambia, 2016)Agriculture in sub-Saharan African region has depended mainly on rainfall since 1990s and crop production has faced negative impacts of extreme climate events which are believed to be manifestations of long term climate ... -
Stability analysis for oil and protein content in soybean (Glycine max L. MERRIL) seed across varying environments
(University of Zambia, 2016)Soybean is an important crop with many important properties. The use of soybean varies from stock feed, biodiesel, edible oils and high protein food products, to soil amendment resulting from its nitrogen fixing ability ... -
Effects of Crop Rotations on Selected Soil Properties and Maize (ZEA MAYS) Yield Under Coservation Farming
(The University of Zambia, 2016)Crop rotation is known to affect the physical, chemical and biological soil properties. This farming system has shown to be effective at reducing the farmers’ costs while increasing the yields in the long run and improving ... -
Suppressive Effects of Sunflower(Hellianthus Annuus L.) on Local Rain-Fed Weeds in Zambia
(The University of Zambia, 2015)One of the constraints to crop productivity is weed infestation. Options in weed management are varied and can be associated with high costs unaffordable by small-scale farmers. Biological weed management through allelopathy ... -
Effect of aqueous neem(Azdirachta Indica A Juss) leaf extract on selected soil chemical and biological properties
(The University of Zambia, 2015)Zambia has soils with low plant available nutrients due to leaching, depletion of organic matter and acidification. One way of addressing this situation is by the application of organic materials such as aqueous neem leaf ... -
Farmer to consumer direct marketing: Consumer preferences and characteristics
(The University of Zambia, 2011)The aim of this study was to evaluate the effect on carcass characteristics of Cobb 500 broiler chickens of supplementing cowpea meal with Methionine and Lysine only as well as supplementing the cowpea with Methionine, ... -
Epidemiological and molecular characterisation of cassava mosaic geminiviruses and the their effect on yield of cassava in Zambia
(The University of Zambia, 2016)An epidemiological and molecular characterization study of cassava mosaic disease was carried out in four cassava growing Provinces of Zambia in 2013. The objectives of the study were to determine the incidence and severity ... -
Inheritance of resistance to Alectra Vogelli in cowpeas(Vignamunguiculata[L} Walp.)
(The University of Zambia, 2015)Alectra vogelii (benth) is a parasitic weed which causes significant yield reduction in cowpea (Vigna unguiculata Walp) in Tanzania. The objective of this study was to (i) identify the type of gene action controlling the ... -
Evaluation of growth, water balance and water use efficiency of selected maize varieties under rai-fed conditions in Zambia
(The University of Zambia, 2015)Maize in Zambia is mostly grown under rain-fed conditions with yields strongly correlated to seasonal rainfall pattern. Because of lack of information of maize varieties that use water more efficiently under rain-fed ... -
Relationship between vine propagation method, and growth and yield in sweetpotato[Ipomoea batatas(l.)lam]
(2015-11-24)Timely availability of high volumes of good quality planting materials is a challenge especially for crops propagated by vegetative means such as sweetpotato [Ipomoea batatas (L.) Lam.]. Zambian growers rely on volunteer ...
