Corn is an important food security crop in Bolivia. Consumption is approximately divided into 77% animal feed and 17% human consumption. However, Bolivian corn production is the lowest among its neighboring countries due to the use of uncertified varieties, lack of fertilizer use, limited agricultural technology, and climate change. Korea Partnership for Innovation of Agriculture Bolivia Center and Bolivian Institute of Agricultural and Forestry Innovation planted synthetic INIAF Guaraní and hybrid INIAF H1 using green manure and Biol (eco-friendly fertilizer) in the Chaco region. Three villages used green manure for crops. Later, INIAF Guaraní and INIAF H1 were sown using Biol. The production and generated income were calculated based on the market price of 1,300 Bs per ton. Traditional farming methods for INIAF Guaraní and INIAF H1 yield 2.4 tons/ha and 5 tons/ha, respectively. By contrast, using green manure and Biol yielded 5.2 tons/ha for INIAF Guaraní (1.8 tons/ha increase) and 6.5 tons/ha for INIAF H1 (1.5 tons/ha increase). Net income from traditional farming methods was 980 Bs, whereas using ecofriendly farming methods to cultivate INIAF Guaraní and INIAF H1 resulted in net incomes of 2,620 Bs and 3,910 Bs, respectively. The project highlights Bolivia’s need to disseminate techniques that use certified varieties and eco-friendly farming methods through demonstrations for farmers and village pilot programs.
