Households’ responsiveness to government ban on polythene carrier bags in Uganda
(American Research Institute for Policy Development, 2015)Polythene carrier bags have become common in Uganda largely due to their desirable properties that are considered convenient by consumers. They have, however, turned out to be a big nuisance and threatening the environment ... -
Improvement of resistance to fusarium root rot through gene pyramiding in common bean
(African Crop Science Society, 2012)Fusarium root rot (FRR), caused by Fusarium solani f.sp. phaseoli, is one of the most serious root rot diseases of common bean (Phaseolus vulgaris L.) throughout the world. Yield losses of up to 84% have been attributed ... -
Influence of host plant resistance and disease pressure on spread of cassava brown streak disease in Uganda.
(SCIENCEDOMAIN International, 2015)Cassava brown streak disease (CBSD) is a major constraint to cassava production in Uganda. The disease is caused by two ipomovirus species: Cassava brown streak virus (CBSV) and Ugandan cassava brown streak virus (UCBSV), ... -
Influence of season and cropping system on occurrence of cowpea diseases in Uganda.
(American Phytopathological Society, 1997)An on-farm survey was conducted for two seasons (first and second rains of 1994) to determine influence of season and cropping systems on occurrence of cowpea (Vigna unguiculata) diseases in Uganda. Viral diseases were ... -
Inheritance of resistance to kernel infection by Aspergillusflavus and aflatoxin accumulation in groundnut
(International Scholars Journals, 2014)Aflatoxin contamination in groundnut is one of the major barriers in international groundnut trade. Aflatoxin may cause human cancer, hepatitis and liver cirrhosis. The objectives of the study were to determine: (i) the ... -
Inheritance of root dry matter content in sweet potato.
(African Crop Science Society, 2014)There has been much emphasis on breeding for increased sweet potato storage root yield, but less on dry matter yield, and its inheritance. High dry matter content (DMC) is associated with consumer preferences, and ... -
Making ICTs relevant to rural farmers in Uganda: A Case of Kamuli District
(Revista Brasileira de Planejamento E Desenvolvimento, 2016-09)ICTs stands for information and Communication Technologies, it has been broadly defined by the Uganda Communication Commission as technologies that provide an enabling environment for physical infrastructure and services ... -
Morphological and genetic diversity analysis of rice accessions (Oryza sativa L.) differing in iron toxicity tolerance
(Korean Society of Crop Science and Springer, 2013)A major emphasis in breeding for iron toxicity tolerance in rice is to identify differences that are associated with resistance and harness them for genetic improvement. In this study, thirty accessions, including IRRI ... -
Pests and diseases on cowpea in Uganda: Experiences from a diagnostic survey.
(African Crop Science Society, 1999)diagnostic survey (DS) using a questionnaire covering 525 farm households was conducted in 1993/94 to determine the status of cowpea (Vigna unguiculata L. Walp) and its production constraints in Uganda. Subsequent on-farm ... -
Population diversity of rice bacterial leaf blight isolates in Uganda
(Pelagia Research Library, 2013)The deployment of resistant cultivars is the best option to control bacterial leaf blight (BLB) and requires an understanding of the pathogen diversity. BLB caused by Xanthomonas oryzae pv.oryzae is a destructive disease ... -
Potential determinants of profits and market efficiency of potato market chains in Uganda
(Emerald Publishing Limited, 2017)Purpose – The study aimed at understanding the level of inefficiencies in the potato market chain. Farmers sell potato to traders but continue to complain of limited market access and low profits. The purpose of this paper ... -
A preliminary analysis of diversity among East African sweet potato landraces using morphological and simple sequence repeats (SSR) markers
(International Society for Hoticultural Science, 2006)East Africa is known to have a wide range of sweet potato landraces and, therefore, is considered to be a secondary center of diversity. In this study, we assessed the diversity among sweet potato landraces from Kenya, ... -
Prevalence of sorghum anthracnose in different agroecologies of Uganda
(National Agricultural Research Organisation, 2013)Nine major sorghum growing agro-ecologies of Uganda were surveyed to establish the sorghum anthracnose incidence and severity. Hierarchical sampling was used. Severity of anthracnose in the field was rated on a scale of ... -
Prevalence of viruses infecting cowpea in Uganda and their molecular detection
(Academic Journals, 2012)The main areas for cowpea cultivation in Uganda were surveyed in June and October 2006 for viruses affecting the crop. Seed and leaf samples from symptomatic and asymptomatic plants were collected from farmers’ fields and ... -
Reaction of rice cultivars to a virulent rice yellow mottle virus strain in Uganda
(African Crop Science Society, 2012)Rice (Oryza spp.) has long been an important food staple for many traditional rice growing communities. Key developments in efforts to improve rice production such as the development of NERICA varieties have been widely ... -
Reaction of waxy and opaque-2 inbreds and their derived progenies to multiple foliar diseases of maize in Uganda
(Canadian Center of Science and Education, 2012)Specialty maize lines possessing important endosperm genes waxy and/or opaque-2 enhance processing and nutritional qualities of the grain. However, production and utilization of specialty maize varieties for food, feeds ... -
Response of improved cassava varieties in Uganda to cassava mosaic disease (CMD) and their inherent resistance mechanisms
(Academic Journals, 2011)Field based trials were setup to evaluate response and inherent resistance mechanisms to cassava mosaic disease (CMD) of four improved varieties; Nase 9, Nase 11, 00036 and 00057 together with Nase 4 and Bao as resistant ... -
Response of local cassava varieties in Uganda to cassava mosaic virus disease
(SCIENCEDOMAIN International, 2012)Cassava mosaic disease (CMD) resistant varieties have been used to manage CMD in Uganda. In spite the availability of a number of CMD resistant cultivars, several local landraces are continually grown in Uganda because ... -
