WE2.1: Can communities of practice help us accelerate and improve our gender research?
https://hdl.handle.net/10568/125590
Abstract
There is often just one gender researcher per project or program team or CGIAR initiative so gender research can be a lonely and challenging business due to lack of collaborative and critical discussion with fellow researchers. Collaboration helps researchers to develop and enrich their theory and practice, and share their experiences, doubts, successes and puzzles /conundrums. Communities of Practice (…

The informal seed business: Focus on yellow bean in Tanzania
https://hdl.handle.net/10568/127069
Abstract
This article explores the informal seed business, focusing on the yellow bean in Tanzania. The yellow bean is a major bean type traded, yet little is known about the seed supply that fuels it. The survey research in 2019 encompassed larger grain traders, informal seed traders, and retailers, covered major production, distribution and sale hubs, and was complemented by GIS mapping of seed and grain flows and DNA fingerprinting of…

Limitations of using simple indicators for evaluating agricultural emission reductions at farm level — evidence from Kenyan smallholder dairy production
https://hdl.handle.net/10568/127070
Abstract
National-scale carbon footprints of livestock production are commonly computed from a set of production system characteristics that serve as inputs for greenhouse gas (GHG) emission models. We evaluated the feasibility of using such equations at a finer scale to derive a simple farm-scale indicator of emission intensity (milk yield per…

Evidence support the potential for climate-smart agriculture in Tanzania
https://hdl.handle.net/10568/127099
Abstract
National governments across Sub-Saharan Africa include climate-smart agriculture (CSA)—context-specific interventions that support resilience, productivity, and climate mitigation—in plans, policies, and strategies to jointly address climate change, agricultural production, and rural livelihood goals. This paper synthesizes the evidence on field-based CSA management practices generated through ten years of research…

Photosynthetic and grain yield responses to intercropping of two common bean lines with maize under two types of fertilizer applications in the colombian amazon region
https://hdl.handle.net/10568/127132
Abstract
Acid soils in the Amazon region are characterized by low fertility and high aluminum saturation causing reduced crop yields. Improving genetic adaptation of crop genotypes together with suitable agronomic management practices can mitigate the impact on crop production in acid soils. The objective of the present study was to…

Influence of simultaneous intercropping of maize-bean with input of inorganic or organic fertilizer on growth, development, and dry matter partitioning to yield components of two lines of common bean
https://hdl.handle.net/10568/127141
Abstract
Intercropping is a common practice among smallholder farmers cultivating common bean (Phaseolus vulgaris L.) and maize (Zea mays L.). It affects agronomic performance, dry matter partition- ing, and grain yield. Simultaneous intercropping of common bean with maize can influence growth,…

Impact of web blight on photosynthetic performance of an elite common bean line in the Western Amazon region of Colombia
https://hdl.handle.net/10568/127154
Abstract
Disease stress caused by plant pathogens impacts the functioning of the photosynthetic apparatus, and the symptoms caused by the degree of severity of the disease can generally be observed in different plant parts. The accurate assessment of plant symptoms can be used as a proxy indicator for managing disease incidence, estimating yield loss, and developing genotypes…

High-throughput virus screening in crosses of South American and African cassava germplasm reveals broad-spectrum resistance against viruses causing Cassava Brown Streak Disease and Cassava Mosaic Virus Disease
https://hdl.handle.net/10568/127155
Abstract
Screening cassava lines for resistance against viruses causing cassava brown streak disease (CBSD) is cumbersome because of the unpredictable and erratic virus infections in the slow plant infection processes that are frequently not associated with distinct leaf symptoms and because…

Labour productivity: The forgotten yield gap
https://hdl.handle.net/10568/127203
Abstract
Crop yields and labour productivity have increased markedly over the past 70 years. In agriculturally advanced countries, increases in labour productivity – that is, increases in the economic output per unit of labour input – have been several-fold greater than corresponding increases in yield. The gap in labour productivity between the Global North and the Global South is now much greater than the yield gap. This large labour productivity gap,…

Influence of weather and endogenous cycles on spatiotemporal yield variation in oil palm
https://hdl.handle.net/10568/127207
Abstract
Oil palm is the major source of vegetable oil in the world and Indonesia is the main palm oil producing country. There is limited knowledge on the factors accounting for spatial and temporal variation in fresh fruit bunches (FFB) yield. Here we investigated relationships between weather and endogenous factors with FFB yield and its components (bunch number and individual bunch weight) using data…

Genetic analysis of resistance to bean leaf crumple virus identifies a candidate LRR-RLK gene
https://hdl.handle.net/10568/127298
Abstract
Bean leaf crumple virus (BLCrV) is a novel begomovirus (family Geminiviridae, genus Begomovirus) infecting common bean (Phaseolus vulgaris L.), threatening bean production in Latin America. Genetic resistance is required to ensure yield stability and reduce the use of insecticides, yet the available resistance sources are limited. In this study, three common bean populations containing a total of…

Abstract
Climate variability affects crop production in multiple and often complex ways. The development and use hybrid crops with greater productivity and tolerance to climate shocks is one of the approaches to climate adaptation and agricultural intensification. Since hybrid crops are more expensive for the producer, risk management is of paramount importance. Here, we pose that there is high…
