    Agronomic Assessment of Upland Rice Varieties under Unpredictable Rains in the Semi-Arid Conditions of South-Western Agro-Ecological Zone of Uganda

    This paper examined agronomic performance of three upland New RICE for Africa (NERICA) varieties promoted by the Government of Uganda in its efforts to improve household food and income security among smallholder farmers. Three rain-fed experimental trials were conducted on station at Mbarara Zonal Agricultural Research and Development Institute (MBAZARDI), with semi-arid climate conditions typical of more than 50% of the South-Western Agro-Ecological Zone (SWAEZ) of Uganda. The experimental trials were established in the long rain seasons that often occur in September-December period. But results for only one successful long rain seasonal trial of 2010 are presented in this paper. Successful experimental trial for upland NERICA had an average precipitation of 130 mm that was well distributed especially from booting stage, which is the most sensitive growth stage for upland NERICA. During the growth period, NERICA 1 and NERICA 4 were significantly taller (p < 0.05) than NERICA 10. NERICA 4 had the highest yields: two-folds that of NERICA 1, but four-folds lower than that obtained in Namulonge Crops Resource Research Institute (NACRRI), the breeder station for NERICA in Uganda. Grain yields of NERICA 4 were also below the national average of rice productivity estimated at 2.5 t·ha-1. Although, NERICA 4 ranked top in terms of grain yields among the tested upland NERICA varieties and therefore, most possible candidate for smallholder rice farmers in the humid parts of the SWAEZ, it called for more breeding for upland NERICA varieties with traits that could increase their tolerance to low soil moisture most prevalent in the SWAEZ.

    Knowledge and Perceptions on Banana Xanthomonas Wilt Control 10 Years after the Epidemics in the South Western Agro-Ecological Zone, Uganda
    (Open Access Library Journal, 2024-06-07) Kankwatsa, Peace; Kyomugisha, Maggiore; Ntakyo, Proscovia Renzaho; Muhumuza, John Bosco
    The East African highland cooking banana (Musa spp.) is a major food security and non-traditional income generation crop in rural and urban areas of the South Western Agro-Ecological Zone (SWAEZ) of Uganda. Being a perennial crop, the vulnerability of banana to the evolving abiotic and biotic stresses is increasing in this major production region. During the late 2000s, the SWAEZ experienced wide-spread and severe banana Xanthomonas wilt (BXW) disease epidemics, which caused 70% - 100% crop and/or yield losses. Through various partnerships, the government of Uganda applied the integrated approaches to provide the needed technical, policy, legal and financial support to rapidly eradicate the disease, strengthen the farmers’ capacities to prevent further plant infections and spread of the “Xanthomonas vasicola pv., musacearum (XVM)” pathogen. Research has shown that the comprehensive and collective action, which focused on rapidly eliminating BXW, reduced the disease prevalence to <5%, but ten years after the eradication campaign, BXW is persistent in SWAEZ. A study carried out in five districts to assess farmers’ knowledge and perception about the BXW control 10 years after the epidemics, found that the disease incidences continue to gradually rise, as efforts to control it continue to decline, which makes the zone prone to another serious epidemic if strong measures are not enforced. Given the knowledge and skills previously imparted to farmers, banana productivity and production for food and income generation have been gradually increasing; livelihoods that are highly dependent on banana have improved and crop production has been diversified in some areas. However, because of the decline in the government’s effort to continue sensitizing, monitoring and enforcing by-laws, the disease inoculum continues to build up and spread. While the majority of the household respondents agreed that the recommended disease control technology packages were very effective, they were also expensive (in terms of labour and non-labour inputs), and too difficult to be applied by the weak and vulnerable community members (females, children, elderly people, sick and other disabled community members). The farmers attributed the disease persistence in the zone to poor monitoring, ineffective use of the recommended disease management technology packages, increased disease pathogen inoculum in abandoned plantations, use of infected planting materials and unsterilized field tools. Therefore, in order to completely mitigate BXW from the SWAEZ, this study recommends that the government reinstate regular awareness creation campaigns, training, and functional BXW eradication task-forces in the banana-producing communities to ensure timely and effective disease control.
