A field study was carried at Gwebi VTC to determine relationships among the morpho-physiological traits associated with drought tolerance in cowpea. Fifteen genotypes were planted in RCBD with three replications under two moisture environm…
We conducted a participatory mapping of natural resources and woody biomass estimation in Canhane Community, Massingir District in Mozambique. The aim of this study was to identify problems and opportunities for natural resources managemen…
Improvement of banana using conventional breeding methods is very difficult due to its biology. Genetic transformation is a novel alternative approach for crop improvement. Transformation of EA-AAA bananas has, however, been limited by dif…
Deforestation has become rampant in many areas in Kenya due to pressure on land resulting from human population increase. Efforts to rehabilitate areas that have been deforested have had little success due to the limited knowledge of veget…
Western Kenya continues to experience food insecurity due to increasing soil acidity and consequent phosphorus deficiencies with 0.9 million hectares of land having pH < 5.5. Liming is one of the interventions recommended to ameliorate …
Food insecurity in sub-Saharan Africa (SSA) results mainly from common and prolonged droughts, fertility depleted soils, poor economies and insignificant researcher-extension-farmer contacts to demonstrate technologies. The soils are predo…
Fusarium solani f. sp phaseoli (FSP) is an important disease in Uganda causing in some cases 100% yield losses in beans. The study established the nature of inheritance to FSP resistance in genotypes RWR 719, NABE 14 and NABE 13. A 5x5 ful…
Groundnut (Arachis hypogeal L.) is an oil crop legume capable of symbiotic nitrogen fixation. Soil acidity is a major limitation to symbiotic nitrogen fixation. Acid soils are widespread in Western Kenya and Eastern Uganda where groundnut …
Poor soil fertility and increased frequency of mid-season droughts due to climate change have made it difficult for urban farmers to get sustainable crop yields especially on sandy soils. Higher yields can be attained by urban farmers if p…
A semi-detailed soil survey of the land of Ikwuano Local Government Area Abia State South East Nigeria was undertaken. The soils were sampled with the aid of soil auger to identify major soil types and their morphological properties (e.g. …
Breeding for drought tolerance requires a clear understanding of the mode of gene action for this trait. To understand the action of drought tolerance genes in upland rice varieties in Uganda, a study was carried out to establish the gener…
A greenhouse experiment was undertaken to evaluate the effects of lime application (at different rates) on soil pH, exchangeable aluminium (Al3+) and plant response to lime application across four of the strongly acidic soils series of Les…
Improving tuber seed quality and availability is institutionally complex in the tropics and sub-tropics. The main objective of this work was to evaluate the effect of superphosphate and plant density on mini-tuber production from true pota…
Soil moisture flow characteristics, infiltration and storage in the root zone determine the overall availability and use efficiency of water in crop production. This study is evaluating the effects of cropping systems and tillage managemen…
Rice in Zambia has traditionally been grown in lowland flooded or semi-flooded environments. These environments are unfortunately only a small portion of Zambia, occupying only 1% of the total land. The increase in food demand in the count…
In this paper we report on findings from a co-learning experience we undertook with smallholder farmers in two areas in Zimbabwe aimed at developing their capacity to apply integrated soil fertility management (ISFM) options to improve foo…
This study examined presence of heavy metals (aluminium, cobalt, copper, iron, lead, manganese, nickel and zinc) along Botswana roads. These metals are toxic to human and animals. The mean values of these metals were below toxic range, ind…
Food insecurity in Kenya is on the increase unless appropriate measures are taken. This is because nearly 80% of the land is arid to semi-arid and therefore not favorable for crop production using the current methods of production. The iss…
The paper reports work aimed at improving livelihoods of smallholders by providing investors, policymakers and implementers with concrete knowledge and tools to make informed investment decisions on small-scale irrigation water management …
Land degradation which among others include loss of vegetation is rampant in Kenya, destroying both the fragile arid and semiarid lands and the non-arid areas. Efforts to rehabilitate semiarid areas by re-vegetation has often failed. This …
Kenyan farmers are threatened by overreliance on few crops whose yields are reduced by adverse climatic changes. Bananas are more resilient and produce year round, making it a more suitable crop. To increase banana production, farmers shou…
The study assessed Mohale dam and the associated rivers’ water quality over 5 years and comparing it to the water quality standards. It was believed that since this dam and the rivers occurred at elevations of between 2000m and 2900m above…
Bacterial blight caused by Xanthomonas oryzae pv.oryzae, is a destructive disease of rice worldwide. Resistant varieties are the best option to avert the disease. Thirty resistance genes identified face a wide genetic diversity exhibited b…
The need for a high degree of experimental uniformity is clearly shown by the fact in an experiment that results in a CV (coefficient of variation) of 20%, 8 replications would be required to detect the size of difference between treatment…
The nitrogen reserve of agricultural soils must be replenished periodically in order to maintain an adequate level for crop production. This replacement of soil nitrogen is generally accomplished by the addition of fertilizers or as produc…
