Integrated Soil Fertility Management Affect Profitability of Soybean in Northern GhanaLarbi A.1, Addul Rahman N.1, Kotu B.1, Hoeschle-Zeledon I.2 Akakpo D.B.3, Mellon S. B.31International Institute of Tropical Agriculture (IITA) – Tamale, Ghana2International Institute of Tropical Agriculture (IITA) - Ibadan, Nigeria3Wageningen University, Wageningen, NetherlandsCorresponding author email: a.larbi@cgiar.orgKey research activitiesA split-plot design with 2 soybean varieties (TGX-1904-6F &Jenguma) as main plots and 5 integrated soil fertilitymanagement (ISFM) methods as subplots. ISFM methods usedinclude: Triple superphosphate at 60 kg/ ha(TSP) , Fertizol at 4 t/ha (F), TSP + F, TSP + F + Boostxtra. Grain and fodder yield weremeasured and benefit cost (BCR) was estimated.Implications of the research for generating development outcomesResults and main findings• Soybean variety affected only fodder yield (Table 1).• ISFM affected both grain and fodder yield (Table 2).• Majority of farmers preferred TSP+F+Boostxtra application onsoybean N (Fig. 1).• ISFM affected benefit cost ratio (Fig. 2).• Jeguma variety may be grown with TSP at 60 kg/ha to increaseyield and profitability.Results from this study can be used for scaling-up activity inAfrica RISING phase 2 to improve soybean productivity in innorthern Ghana.How this work would continue in Africa RISING phase 2The Africa Research In Sustainable Intensification for the Next Generation (Africa RISING) program comprises three research-for-development projects supported by the United States Agency for International Development as part of the U.S. government’s Feed the Future initiative. Through action research and development partnerships, Africa RISING will create opportunities for smallholder farm households to move out of hunger and poverty through sustainably intensified farming systems that improve food, nutrition, and income security, particularly for women and children, and conserve or enhance the natural resource base.The three projects are led by the International Institute of Tropical Agriculture (in West Africa and East and Southern Africa) and the International Livestock Research Institute (in the Ethiopian Highlands). The International Food Policy Research Institute leads an associated project on monitoring, evaluation and impact assessment.www.africa-rising.net Current :  Ministry of  Food and Agriculture (MoFA)Future: 1) Agricultural Technology Transfer project (ATT)2) Agricultural Development and Value  Chain  Enhancement  Program (ADVANCE)Current partnerships and future engagements for out scalingISFM Grain yield (kg/ ha) Fodder yield (kg/ ha)Farmer practice 971.7 1833.4TSP at 60 kg/ha 1435.4 2955.8Fertizol (F) at 4 t/ha 1289.4 2758.3TSP + F 1671.1 3182.6TSP + F + Boostxtra 1563.8 3006.4s.e 141.97 180.33P-value 0.0081 <.00010 20 40 60 80 100Farmer PracticeTSP+FFertisol (F)TSPTSP+F+BoostxtrraNumber of farmersTotalMaleFemaleaabbb0 0.5 1 1.5Farmer practiceTSPFertizol (F)TSP + FTSP + F + BoostxtraBenefit cost ratioVariety Grain yield (kg/ ha) Fodder yield (kg/ ha)Jenguma 1374.3 2925.9TGX-1904-6F 1398.3 2568.8s.e 88.99 88.81P-value ns 0.0361Table 1: Effect of  variety on grain yield and fodder yield of soybeanTable 2: Effect of IFM on grain yield and fodder yield of soybeanFig. 1: Farmer preference for ISFM on soybeanFig 2: Effect of ISFM on benefit cost ratio
