Lima beans, often known as “butter beans” for their creamy texture, are gaining popularity for their remarkable nutritional value and health benefits.
These beans are a powerhouse of plant-based protein, fiber, and essential vitamins and minerals, making them a great addition to any balanced diet.
In Uganda, their appeal is rising among health-conscious individuals and those seeking natural ways to enhance their nutrition.
Evanice Manyiraho, a herbal farmer from Kicwamba in Kabarole district, has long understood the potential of lima beans.
For her, this versatile crop is more than a source of sustenance—it’s a path to wellness and an opportunity for local farmers to support both their health and livelihoods.
Through her extensive experience in herbal farming, Manyiraho has gained insight into cultivating and maximizing the benefits of lima beans, a crop she believes holds untapped potential in Uganda’s agricultural landscape.
Health benefits of lima beans
Lima beans are an excellent plant-based protein source, making them ideal for vegetarians and people seeking to reduce their meat intake.
“Protein is essential for muscle repair and development,” Sharon
Naluwende, a nutritionist at Mulago Hospital notes adding that ‘with lima beans, you can get a substantial amount of it without relying on animal sources.’
Lima beans are high in dietary fiber, which aids in digestion, helps maintain a healthy weight, and reduces the risk of heart disease by managing cholesterol levels.
Blood sugar management
Because of their low glycemic index, lima beans can help regulate blood sugar levels, making them a favorable choice for people with diabetes or those trying to prevent it, says Naluwende.
“The complex carbohydrates in lima beans release energy slowly, reducing blood sugar spikes and helping sustain energy over a longer period,” she adds.
Manyiraho mentions that many people in her community are turning to lima beans as a natural option for managing their blood sugar.
Packed with essential nutrients
Lima beans are loaded with nutrients, including iron, potassium, and magnesium. These nutrients support various functions like blood circulation, heart health, and strong bones.
“Iron deficiency is common, especially among women, and adding lima beans to one’s diet can help boost iron levels naturally,” explains Manyiraho.
She adds that they also contain folate, essential for pregnant women as it promotes fetal health and development.
Manyiraho’s journey as a farmer has given her deep insights into cultivating crops that benefit her community.
She shares her knowledge on growing lima beans, highlighting that they’re resilient and relatively easy to maintain.
Soil preparation
Lima beans thrive in well-drained soil rich in organic matter.
Manyiraho advises farmers to add compost or aged manure to enrich the soil.
“Good soil is the foundation. Once the soil is prepared, it ensures the beans grow strong and healthy,” she says.
Planting and spacing
She recommends planting lima bean seeds about 1–2 inches deep, spaced around 6 inches apart. Proper spacing is essential to avoid overcrowding, which can lead to diseases and poor yield.
“Crowded plants compete for nutrients, so spacing gives each plant the chance to grow well,” she advises.
Watering and maintenance
While lima beans are drought-tolerant, they need regular watering during their initial growth stages.
“Once they’re established, you don’t need to water as much,” Manyiraho explains, “but keep an eye out for pests and weeds.”
She recommends weeding by hand to avoid harming the plant roots and suggests applying natural pesticides to ward off pests.
Harvesting and storage
Lima beans are ready for harvest when the pods are firm and filled out.
Manyiraho emphasises the importance of harvesting at the right time to maintain the best flavor and nutritional value.
“Let them dry on the plant if you want beans for storage,” she says, adding that dried beans can be stored for several months, ensuring a consistent supply.
