Weed Management for Optimal Yield
This technology helps farmers grow beans more effectively by dealing with the problem of weeds. Weeds can take away important nutrients and sunlight from the bean plants, making them weaker and giving less harvest. This technology offers two main solutions: using special chemicals or machines to get rid of the weeds. These methods are much faster and easier than doing it by hand. It's like giving the beans a better environment to grow in, so they can be healthier and give more beans for the farmers. This is especially helpful for small-scale farmers who may not have a lot of people to help with the hard work. Overall, this technology makes bean farming more efficient and helps farmers get better harvests.
This technology is TAAT1 validated.

Utilizing this technology enhances agricultural productivity, improves weed management efficiency, reduces labor and costs, bolsters food security, and stimulates economic growth in farming communities. It also advances sustainable practices, facilitates job creation, and enhances farmers' livelihoods.
Consider the following cost structure:
Pre-emergence herbicides and labor cost approximately US $27 per hectare.
Mechanical weeders range between US $250 and $500, depending on type and attachments.
Cost breakdown for single-row motorized weeders: Equipment is about US $7 per hectare, while labor is approximately US $39 per hectare, totaling US $46 per hectare.
There is potential for cost reduction with larger, multiple-row weeders.
Maintenance is required for knapsack sprayers and power weeders.
Training is essential for successful implementation. Additionally, include delivery costs to the project site and account for import clearance and duties if applicable, considering the technology's availability in various countries. Key partners such as agro dealers are necessary.
Estimate the profit realized with this practice, noting that in Ethiopia, implementing weed management strategies yields a net profit of US $743 per hectare, a 35% increase compared to conventional hand management.
