Enhancing Rice Markets in Uganda through Smart Micronutrient Fertilization (ENRICH)
Duration: January 2016 – January 2019
Aim: Rice is an important crop with rapidly growing demand in Uganda. 90% of the increased production resulted from land expansion, while yields remained stagnant. Fertilizers are barely used and yield responses to conventional NPK-fertilizers are poor. On-farm trials reveal that addition of micronutrients to NPK significantly increases yields. The benefits from adding micronutrients include increased yield, improved grain quality, increased uptake efficiency of NPK-fertilizers and increased economic returns. These mutually reinforcing benefits may incentivise farmers to buy and use fertilizers. Yet, uptake efficiency of soil applied micronutrients is low. Innovations in nutrient packaging and delivery mechanisms are needed. Foliar application and nano-packaging both show promising potential to increase plant uptake. The aim of this project is to fine-tune the composition of micronutrients required and their mode of application to realize multiple benefits.
Objective: The main objective of this project is to increase food security and income of smallholder farmers producing lowland rice with the main objective to significantly increase the productivity of lowland rice in Eastern and Northern Uganda. Specific objectives are:
- Understand the current situation and rice fertility challenges in the region.
- Evaluate and identify the appropriate composition and mode of application of micronutrients (SmartFert) for optimum yield of lowland rice.
- Integrate and out scale SmartFert into ongoing development programs and production practices, and support institutional and research capacity for rice sector development.
Method: Findings of the project will be disseminated throughout the value chain, and policymakers will be informed to be able to create an enabling environment for further development.
Dutch policy goals: Increased sustainable agricultural production; and Improved access to better nutrition.
Year 1: Rice is a very important crop for the smallholder farmers in Uganda. However yields are very low (2.5t/ha). ENRICH aims to increase food, nutrition and income security of smallholder lowland rice farmers through testing and recommending best micronutrient and NPK fertilizer management strategies for optimum yields and nutritional quality. Preliminary results conducted in partnership with Farmers’ Research Groups (FRGs) at Doho and Kibimba, Eastern Uganda indicate that additional average yield increment of 0.76t/ha can be obtained when micronutrients are applied in combination with NPK, bringing in additional $434/ha for a farmer who has been using NPK alone. However, an average yield increment of 2.41t/ha, equivalent to an additional $1,377/ha can be achieved when a farmer who has not been using any fertilizer at all, adopts best NPK and micronutrient fertilizer strategies. Through workshops and farmers’ field days, stakeholders are greatly interested and keen to try the technologies on their own.
Year 2: Rice is an important food staple and a major source of income among smallholder farmers in Uganda, however, yields are low (2.5t/ha). ENRICH therefore, aims to increase food, nutrition and income security of smallholder lowland rice farmers through testing and recommending best micro-macronutrient fertilizer strategies for optimum yields and nutritional quality. Preliminary results of field trials conducted with participation of Farmers’ Research Groups (FRGs) show an average yield increment of 2.41t/ha (1st trial) when a farmer who has not been using any fertilizer, adopts best NPK and micronutrient fertilizer strategies and, good agricultural practices. Through trainings and participation in the fertilizer trials, some farmers have already begun to apply the knowledge and, yield increase of up to 1.5t/ha reported with fertilizer use. The findings have generated great interest from all stakeholders in the rice value chain; who are keenly waiting for the best fertilizer management option(s) to be recommended for adoption.
