This study has analyzed the factors affecting common bean production and marketing decisions by agricultural households in Malawi. The empirical results from applying the triple hurdle model to the IHS3 data demonstrate that different sets of factors affect smallholder farmers’ production, market participation and the intensity of participation decisions with respect to common beans. The location of the farmer, ownership of a radio, receipt of production extension services and FISP benefits, distance to main road and distance to the nearest market affected the agricultural household’s decision to produce common beans.

Nitrogen fixation by leguminous plants is especially important when farmers are trying to minimise fertilizer use for cost or environmental reasons. This second edition of the highly successful book, first published in 1991, contains thoroughly updated and revised material on the theory and practice of nitrogen fixation in tropical cropping systems.

This research examines the extent of market integration among different bean markets across Malawi. Market integration is an indicator that efficiency exists within the flow of information between markets. The study focused on beans as they are a cheap source of protein affordable by the majority of rural smallholder farmers. Market price data for beans was obtained from the Ministry of Agriculture and Food Security and covered the period 1995 to 2011. The markets included in the study are Chitipa, Rumphi, Mzuzu, Lilongwe, Mitundu, Lizulu, Lunzu, Luchenza, and Bangula. Like prices of other agricultural crops, bean prices follow a general seasonal pattern, rising with increasing time since the last harvest and decreasing during the harvest period. Bean prices typically peak in December when bean supply to the market is low. The research results show that beans prices in different markets move in the same direction, meaning that the markets are co-integrated. However, price information is not fully transmitted between markets. Transaction costs were found to be higher in markets which are far away from major cities and in those markets serviced by poor roads. Based on the results, the study recommends the need to improve infrastructure and market information systems to enhance bean market efficiency in Malawi.

In this Policy Note, we examine both household and spatial factors that may drive participation by smallholder farming households in commercial value chains for pulses, legume crops that are primarily harvested for their dry seed. Here the focus is on value chains for common bean (Phaseolus vulgaris), cowpea (Vigna unguiculata), and pigeonpea (Cajanus cajan). Bean and pigeonpea are particularly important secondary crops within many smallholder farming systems in Malawi, while cowpea is less common. All are commonly grown as intercrops in smallholder farming systems, primarily with maize.

Soil degradation and nutrient depletion have become serious threats to agricultural productivity in Africa. Soils cannot supply the quantities of nutrients required and yield levels decline rapidly once cropping commences. This book addresses these issues and includes papers from an international symposium held at Cotonou, Benin, October 9-12, 2000, organized by the International Institute of Tropical Agriculture, Ibadan, Nigeria and the Department of Land Management of the Katholieke Universiteit Leuven, Belgium. In five main parts it marks the end of a first phase of collaborative research on "Balanced Nutrient Management Systems for the Moist Savanna and Humid Forest Zones of Africa" and concludes with recommendations, providing essential reading for crop and soil scientists.

Smallholder farmers in low and middle income countries often sell the bulk of their marketable surplus immediately after the harvest, when prices are at their lowest. As part of a field experiment that tests the effectiveness of both income and expenditure planning to nudge farmers into delaying sales of cash crops, we collected detailed information about market participation from a sample of about 3,500 semi-subsistence farmers in Malawi. In this report, we use this data to describe the situation at baseline, before the intervention was implemented. The focus is on three crops that are (also) important to obtain cash. We provide a detailed account of sales transactions in 2021 and also inquire about price expectations in the near future. We also provide suggestive evidence that prices obtained in the past influence price expectations.
