“…In Uganda, groundnut is the second most important food legume after common beans (Phaseolus vulgaris L.) (Okello et al 2014;Kabeere and Wulf, 2008). The crop is popular, especially in the eastern and northern regions of the country where it has become part of peoples' culture (Rooner and Giller, 2012;Mugisa et al 2015). It is grown throughout the country in diverse environments including both dryland and rain fed conditions (Rooner and Giller, 2012).…”

A participatory rural appraisal was conducted in selected groundnut growing areas of Uganda to determine how smallholder farmers perceive and cope with drought, identify farmers’ constraints, and study the production systems, and varietal preferences in groundnut production. Majority of farmers surveyed, agreed that drought is a major production constraint. The local drought perceptions were described by farmers (55.7%) as warm/hot windy conditions in eastern (55.7%), while in the northern region, little rainfall (82.5%) and hot sunny weather in the mid-western region (48.3%). The majority of farmers surveyed, 81.7%, 77.6%, and 86.6% from eastern, northern and mid-western region, respectively, indicated that the major impact of drought was low yields. However, most of farmers especially from northern and mid-western grow landraces and use early planting to cope with drought. Therefore, knowledge of farmers’ perceptions on drought and coping strategies provides an entry point for improving farmers’ preferred varieties for drought tolerance.

“…Literature pertaining to differences in plant growth of landraces versus improved varieties is not well documented. However, results from studies by Kakeeto (2018) found that plant height of groundnut materials tested in Uganda Reaction of selected improved groundnut varieties and landraces to natural pest and disease infestations Another important selection criterion used by groundnut producers is the pests and disease reaction (Okello et al 2010, Mugisa et al 2015). The reaction of groundnut varieties to pests and diseases didn't signi cantly differ between landraces and improved varieties, even though incidence of pests and diseases was lower on improved varieties.…”

Groundnut (Arachis hypogaea L.) is important for providing food, income, livestock fodder for smallholder farmers, and improving soil fertility. However, groundnut yields on farmers’ fields in Sub-Saharan Africa are still very low due to various constraints. Several groundnut cultivars are available within the farmer’s domain but the adoption of these varieties favours landraces as opposed to improved varieties. Limited information is available on performance of commonly grown cultivars for guiding selection by different user groups (farmers, breeders and other users). This study was thus designed to determine the performance of selected landraces and improved groundnut varieties in Uganda. 23 groundnut lines with varying degrees of tolerance to a range of stresses were evaluated at two sites. Results showed significant (P ≤ 0.05 to P≤ 0.001) differences among genotypes for yield. Significant (P≤0.05 to P≤0.001) varietal differences were also observed between landraces and improved varieties for growth and physiological traits but not for pest and disease reaction. Clustering was not evident on the basis of either landraces or improved cultivars for pests and diseases incidences. However, associations of a mix of both groundnut classes of with particular diseases and/or pests were observed. Varieties such as India, Serenut 10, Kabonge, and DOK Tan associated with diseases such as rosette virus disease and its vector pest, the aphids. The results reported in this study shall be useful for driving the development of new cultivars owing to their good adaptability and acceptance thus the need to conserve and ensure sustainable use of these germplasm.

“…In conjunction with nutrient balances, examination of the relationships among household demographic/socioeconomic characteristics and management practices can elucidate the factors driving farmer decision-making and further contextualize and assess the sustainability of agroecosystems (Nkonya et al, 2005;Ebanyat et al, 2010a). Socioeconomic and demographic factors such as gender of the household head or crop planner (Nijuki et al, 2008;Tanellari et al, 2014;Mugisa et al, 2015), land tenure (Place and Otsuka, 2002;Kassie et al, 2015), ethnic group (Naughton-Treves, 1997Kirner, 2010), and field distance from the homestead (Tittonell et al, 2005(Tittonell et al, , 2013Zingore et al, 2007a) have been shown to drive farmer practices and affect farmer access to, use, and decisions regarding resources like residues (Barrett and Bevis, 2015).…”

Through symbiotic biological nitrogen fixation (BNF), grain legumes, such as groundnuts, can enhance soil nitrogen (N) and be an important source of N fertility, as well as a critical component of human nutrition and food security. Because legumes obtain N from soil N stocks as well as BNF, legume residues are key to capturing potential N benefits for soils, which may contribute to increased yields and food production. Here, we conducted a detailed survey at household and field level within a six-village corridor along the western boundary of Kibale National Park (KNP) in western Uganda. We focused on groundnut production and residue management practices and soil organic carbon (SOC) and total N (TN) in fields managed by 100 different households. We also determined SOC and TN in adjacent uncultivated KNP soils. We tested for relationships between socioeconomic factors and farmer groundnut management practices. We calculated a partial N balance and estimated potential N benefits under three scenarios for groundnut BNF. Within the study area, groundnut residue management varied greatly with 51% of surveyed farmers retaining residues on fields through spreading or incorporation, and 49% removing residues, either by transfer to banana groves or burning. Groundnut population density was relatively high with 43% of fields having >30 plants m−2. Despite providing net N inputs of up to 27 kg N ha−1, there was no observed effect of groundnut residue management practices on SOC, TN, or soil C:N ratios. Compared to uncultivated KNP soils, groundnut fields had lower mean levels of SOC and TN and wider C:N ratios. These values are consistent with cultivated soils; however, losses of SOC and TN were lower compared to losses previously reported for conversion from tropical forest to agricultural use. We found that farmer valuation and perception of groundnut residues were influential factors in residue management practices. Overall, we estimated that groundnut residues have the potential to contribute to SOC and TN stocks if retained in the field, but, conversely, removal will result in sizable losses. We find that both environmental and social contexts must be considered when recommending legumes for N provisioning services.
