Profitability of diammonium phosphate use in bush and climbing bean-maize rotations in smallholder farms of Central Burundi

Article purchasedSoil fertility decline is a major constraint to bean (Phaseolus vulgaris L.) and maize (Zea mays) production in the Central Highlands of Burundi. Nutrient sources, specifically fertilizers, are paramount to increasing the production in the regions. Hence, improving fertilizer use efficiency is considered as a key factor towards sustainable intensification. The use of grain legumes with low harvest indices, such as climbing beans, are assumed to improve soil fertility and fertilizer use efficiency. This study compares the rotational effects of bush and climbing bean varieties on maize and evaluates the profitability of diammonium phosphate (DAP, 18–46-0) fertilizer in the bean-maize rotations in 59 smallholder farms of Mutaho district, Gitega Province in Central Burundi. The application of DAP fertilizer significantly increased the grain yields by 14% and 21% for bush and climbing beans, respectively (P 2 $$−1) in a climbing bean-maize rotation while 45% of the farmers in a bush bean-maize rotation. Regression tree analysis showed that targeting fertilizer use to soils with higher C and clay content, and ensuring timely planting are the predominant factors to ensure fertilizer response and profitable returns. This study confirms the need for integrated soil fertility management (ISFM), and that a combination of judicious fertilizer use, an improved grain legume (climbing bean) and adjustment to local conditions (targeting to responsive soils) maximizes economic returns of legume-cereal rotation systems

Bean utilization and commercialization in great lakes region of Central Africa: the case of smallholder farmers in Burundi

This paper evaluates production and commercialization constraints that prevent smallholder farmers from effectively utilizing beans with regard to household food and income security. The study was conducted in six provinces of Burundi in 2010 using a multi-stage stratified sampling procedure to select a sample of 380 smallholder bean farmers. Linear regression models were used to estimate factors influencing the quantity of beans marketed by smallholder farmers. Different ways in which beans are utilized include household consumption, selling, gifts and as seeds. Both improved and local seeds are used, with over 65% of farmers in Muyinga planting local varieties. Results showed that highly educated farmers were more likely to increase commercialization by 10%. However storage of beans for food was more likely to reduce commercialization by 23% while those who gave out beans as gifts had a higher (12%) chance of commercialization. Transport losses were likely to reduce commercialization by 15%, but knowledge of bean networks and access to information from traders was likely to increase bean commercialization by about 10%. Emphasis on interventions (information and extension services) that increase farm level productivity and market led approaches between potential buyers of beans and rural communities will help to reduce poverty and address food insecurity in rural areas

Factors influencing small-holder farmers\u2019 bean production and supply to market in Burundi

Common bean ( Phaseolus vulgaris L) is a major staple food in Burundi; thus increasing its production and marketing has the potential for raising incomes of the farming households. In the country, bean outputs have been declining for decades, yet demand for the crop in East Africa has surged considerably. This study was conducted in Burundi to assess the determinants of quantity produced and marketed by smallholder farmers. A total of 380 farmers obtained through a multistage sampling technique, constituted the study sample. Constraints to production and supply of beans to markets include lack of productive assets, lack of improved varieties and inadequate use of fertilisers. Results with regard to these constraints indicate that a unit increase in the value of productive assets is likely to lead to about 10 percent increase in production of beans; while changing to improved bean varieties may increase production by 22%. In addition, a kilogram increase in fertiliser use is likely to raise bean quantities produced by about 10%. Constraints that affect quantities of beans marketed by farmers include levels of production and losses due to transport problems. Thus, an increase in quantity produced will lead to an almost 30% increase in marketed quantities, while reduction in transport losses will lead to an increase in marketed quantities by about 12%. However, an increase in quantity of beans stored for food will lead a reduction in marketed beans by about 19%, implying that storage of beans may not be targeted at the market but for food security purposes. Efforts that promote collective action among farmers while encouraging increasing the proportion of land under beans are likely to enhance bean production and consequently marketable surplus.Le haricot commun ( Phaseolus vulgaris L) est une nourriture principale au Burundi; ainsi l\u2019augmentation de sa production et son marketing est un potential pour accro\ueetre les revenus familiaux de ressources agricoles. Dans le pays, la production de haricot a connu une baisse depuis bon nombre de d\ue9cennies, alors que la demande en cette denr\ue9e s\u2019est accrue consid\ue9rablement en Afrique de l\u2019Est. Cette \ue9tude \ue9tait men\ue9e au Burundi pour \ue9valuer les d\ue9terminants de quantit\ue9s produites et marchandes par les petits fermiers.

Les contraintes \ue0 la production et \ue0 la fourniture de haricot sur le march\ue9 comprennent le manque de mat\ue9riel productif, manque de vari\ue9ti\ue9s am\ue9lior\ue9es et l\u2019utilisation non ad\ue9quate des fertilisants. Les r\ue9sultats en relation avec ces contraintes indiquent que l\u2019accroissement d\u2019une unit\ue9 de valeur du mat\ue9riel productif entra\ueene environ 10% d\u2019augmentation de la production de haricot, alors qu\u2019en utilisant des vari\ue9t\ue9s am\ue9lior\ue9es la production serait accrue de 22%. En plus, une augmentation d\u2019un kilogramme de fertilisants pourrait accro\ueetre les quantit\ue9s de haricot produites d\u2019environ 10%. Les contraintes qui affectent les quantit\ue9s de haricot fournies sur le march\ue9 par les fermiers incluent les niveaux de production et pertes dus aux probl\ue8mes de transport. Ainsi, l\u2019augmentation en quantit\ue9 produite induira environ 30% d\u2019accroissement de quantit\ue9s fournies, alors qu\u2019en r\ue9duisant les pertes li\ue9es au transport induira une augmentation en quantit\ue9s marchandes d\u2019environ 12%. Cependant, une augmentation en quantit\ue9 de haricot sctock\ue9 pour consommation induira une r\ue9duction de la quantit\ue9 marchande de haricot d\u2019environ 19%, impliquant que le stockage de haricot ne pourrait \ueatre vis\ue9 au march\ue9 mais plut\uf4t pour s\ue9curit\ue9 alimentaire. Efforts qui favorisent l\u2019action collective entre les agriculteurs tout en contribuant \ue0 l\u2019am\ue9lioration des champs de haricots pourraient aussi augmenter la production du haricot et par cons\ue9quent un surplus de vente
