This study was conducted to evaluate the symbiotic effectiveness of Rhizobium isolates using soybean and Phaseolus bean as host plants grown in acid soil (pH 4.5 and 5) from two southern districts of Rwanda. For this purpose, 10 and 33 iso…
The smallholder farming sector in much of the developing world relies on the use of farm-retained seed. The availability of good quality disease free seed is important in enhancing food security but seed-borne viruses can be a major proble…
Farmers across Uganda have developed their own indicators of soil quality but their mechanisms, reliability and sensitivity have not yet been examined. Therefore, this research is intended to address these gaps. Specific objectives include…
We examined abundance and diversity of rhizobia, arbuscular mycorrhiza fungi, nematodes, collembolan, termites, earthworms, ants and beetles in forest, grassland, mixed cropping, fallow, sugar and tea plantation; encompassing Mabira forest…
Pigeon Pea (Cajanus cajan) remains a relatively untapped food legume crop in Uganda and in many parts of Africa mainly due to lack of promotion and availability of varieties that meet producer and consumers needs. The crop is a rich source…
The study evaluated the performance of the centre pivot sprinkler irrigation system and its effects on sugar cane yield at Kagera Sugar Estate. The study also examined soil parameters that influence cane yield and the quality of irrigation…
This on-going study is examining the linkage between termite prevalence and residue amount under conservation agriculture in Zimbabwe. Preliminary results show that convectional ploughing had lowest termite abundance while tied ridging inc…
Clarias liocephalus is a data-deficient air breathing cat fish in wetlands of Western Uganda. It is highly demanded as live bait in Nile perch fishery of Lake Victoria and as food by local communities. Because of high demand, smaller sizes…
The study assessed the agronomic effectiveness of fertilizer use recommendations in western Kenya on maize yields. The treatments included: FURP – 75kg N/ha CAN and 26kgP/ha DAP; 2) FURP – 75kg N/ha CAN and 26kgP/ha DAP plus lime (2t/ha); …
In Malawi development of aquaculture is constrained by, among other factors, lack of good quality seed. Through Research into Use (RiU) the Government of Malawi has mandated a few fish hatcheries, of which the most prominent is the Commerc…
Poor soils, erratic rainfall, frequent dry spells have been cited as the major threats to the development agricultural in Southern Africa. This experiment was designed to evaluate the benefits derived from post planting tied ridging, conse…
High total ammonia nitrogen (TAN) concentrations were introduced to an Algal Turf Scrubber developed under loadings of Clarius gariepinus recirculating aquaculture system effluent to determine its potential and dynamics of TAN removal. TAN…
An experiment was conducted at Bunda fish farm from November 2009 to February 2010. Juveniles of Tillapia rendalli of average weight 9.5 ± SD 0.5g were stocked in outdoor concrete tanks and fed on diets of different plant protein sources f…
A study was conducted to establish the contribution of Eragrostis superba, Enteropogon macrostachyus and Cenchrus ciliaris in improving soil hydrological properties in semi-arid Kenya. Kamphorst rainfall simulator was used on bare ground a…
This paper provides an overview of the research to be conducted in Lake Malombe in Malawi. The changes that have taken place in Lake Malombe fishery have had major social and economic consequences on communities around the lake. In Malawi,…
This study was undertaken to assess the effect of different inoculants on nodule formation and legume yield. On farm experiments were carried out in Bungoma district of western Kenya with treatments arranged in RCBD design with single repl…
Life history traits of Lethrinops gossei from south east arm of Lake Malawi were studied. Validation of age was done by using analysis of marginal increment and length frequency distribution. It was assumed that a single opaque ring was la…
The widespread fragmented adoption of improved soil fertility management options among smallholder farmers can partly be attributed to poor diffusion of acquired knowledge. Using participatory action research approaches, a study was conduc…
This research established the water balance resulting from the clay irrigation for beans (Phaseolus vulgaris L.) and Amaranths (hypochondriacus) grown under different plant density per pot and different precedent soil moisture. Results rev…
This study being conducted in eastern Uganda, is examining the potential of aquaculture as an alternative enterprise to the previously vibrant but now collapsed coffee farming. The study site is highly populated with no lakes. The study is…
The parasitic weed Striga poses a serious threat to cereal production in sub-Saharan Africa. Infestation usually results in significant yield losses, quite often over 70%. Many control options have been reported but, the effect of soil fer…
The research will analyze value chain of Barbus paludinosus and Oreochromis shiranus chilwae from Lake Chilwa in Malawi. It will examine problems of asymmetric bargaining power in fish sales and information flow on the distribution of bene…
A study to investigate factors that influence prices of fish was conducted in Lilongwe, Salima, Kasungu and Mchinji districts of the Central Region of Malawi. Market type, form of preservation, species type, length of fish, weight of fish,…
Climate change has modified the distribution and productivity of many organisms including freshwater species. It has also affected biological processes with eventual alterations in the food webs. Fishers and fish farmers will bear the full…
Assessing soil quality is important so as to learn about the effects of management practices on soil function, create awareness and education, and provides a basis for evaluation of alternative practices. Soil quality often cannot be direc…
