Soil acidity with associated low nutrient availability is one of the major constraints to soybean production in southwestern Ethiopia. Integrated use of lime and acid-tolerant crops is believed to reduce soil acidity and improve crop production. The experiment was conducted in the field condition of Mettu, southwestern Ethiopia during the 2017/18 main cropping season. The experiment comprised fifteen soybean genotypes and two soil amendment (lime and unlimed) treatments arranged in a split-plot design with three replications.

Cassava is a perennial crop that can adapt to periods of drought at different times in a growing season, which permits scheduling planting and harvest to develop production systems supplying roots continuously. However, farmers plant and harvest cassava at the onset of rains which creates glut and results in unattractive root prices.

Rohu Labeo rohita (Hamilton) is an economically and culturally significant aquaculture
species in Bangladesh. However, until recently, genetically improved rohu strains have not
been available to Bangladeshi farmers. In 2020, a multiplier population comprised of
highly-ranked families from the third selected generation of the WorldFish Rohu Genetic
Improvement Program (the ‘G3 multiplier’) was released to commercial hatcheries as
spawn. This spawn was subsequently developed into broodstock by these hatcheries and

This report presents one of three case studies undertaken as part of a broader study to explore and develop models for the emergence of enhanced and resilient seed systems in fragile state contexts. Such contexts provide a particular challenge for seed system development. Existing formal seed sector development models are not viable in fragile states due to a severe lack of capacity, insecurity, and ongoing political and economic instability. The formal seed sector is either weak or non-existent in fragile states, and farmers necessarily rely on the informal seed sector.

The kick off workshop of the CGIAR Initiative on Sustainable Animal Productivity for Livelihoods, Nutrition and Gender inclusion (SAPLING)—took place on 20-21 April in Son La Province, Vietnam. The workshop was co-hosted by the Sub-department of Animal Health and Livestock Production and Fisheries, Son La Province (Sub-DAH), the International Livestock Research Institute (ILRI) and the Alliance for Bioversity International and CIAT (ABC).

Farmers in developing countries routinely misperceive or misreport input quality for various reasons, which introduces substantial measurement error in farm survey data. In this paper, we motivate and illustrate, both analytically and empirically, the inferential and behavioral implications of misperception and misreporting using a unique crop variety identification data from Nigeria. Using a non-parametric framework for testing the presence of measurement error, we show that crop variety misclassification in our data is mostly driven by misperception.

Providing farmers with essential agricultural information and training in the era of COVID-19 has been a challenge that has prompted a renewed interest in digital extension services. There is a distinct gender gap, however, between men’s and women’s access to, use of, and ability to benefit from information and communication technologies (ICTs).

In Mozambique, smallholder farmers commonly grow rice under rainfed systems with limited fertilizer
application; thus, productivity remains very low. Moreover, the adoption rate of improved rice varieties
is as low as 3 per cent, partly because these varieties usually require an irrigated environment with
the use of fertilizer. Green super rice (GSR) varieties are expected to sustain high yield potential under
severe stress conditions. This article used farm-level survey data collected in Mozambique to assess

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, development, and dry matter partitioning of grain of common bean.

Maize cropping systems in Kenya, as is true in many other places in Africa, face multiple biotic and abiotic stressors not least climatic ones. Guided by farmers' priorities, maize breeding programs can contribute to the needed resilience against these changes by developing and mainstreaming new generations of maize varieties adapted to these challenges. Using data from 1,400 farmers and applying a multi-criteria choice analysis, this study reports on smallholder farmers' relative valuation of stress tolerance traits.

germplasm for the benefit of farmers and consumers of the Global South during and after the Green Revolution. Understanding farmers’ heterogeneous preferences for varietal traits in different market segments and incorporating the prominent ones in crop breeding programs are expected to facilitate a faster diffusion of these new varieties. Albeit knowing little about farmers’ trait preferences in South Asia, public-sector breeding programs prioritize yield enhancement and risk reduction over other varietal traits.

Yam (Dioscorea spp.) is a staple food crop and a source of income for millions of people in West Africa. Traditionally, in West Africa, yams are grown without any external inputs, leading to low tuber yields. The rapid decrease of tuber yield observed after the first yam cropping season has been ascribed to nutrient depletion and/or to the accumulation of yam-specific pests and diseases. This has led farmers to grow yam on new surfaces under fallow each year.
