What are pulses?

Pulses are a type of leguminous crop that are harvested solely for the dry seed. Dried beans, lentils and peas are the most commonly known and consumed types of pulses.

Pulses do not include crops which are harvested green (e.g. green peas, green beans)—these are classified as vegetable crops. Also excluded are those crops used mainly for oil extraction (e.g. soybean and groundnuts) and leguminous crops that are used exclusively for sowing purposes (e.g. seeds of clover and alfalfa).

What are some examples of pulses?

You probably already eat more pulses than you realize! Popular pulses include all varieties of dried beans, such as kidney beans, lima beans, butter beans and broad beans. Chick peas, cowpeas, black-eyed peas and pigeon peas are also pulses, as are all varieties of lentils.

Staples dishes and cuisines from across the world feature pulses, from hummus in the Mediterranean (chick peas), to a traditional full English breakfast (baked navy beans) to Indian dal (peas or lentils).

Why are they important crops?

Pulses are essential crops for a number of reasons. They are packed with nutrients and have a high protein content, making them an ideal source of protein particularly in regions where meat and dairy are not physically or economically accessible. Pulses are low in fat and rich in soluble fibre, which can lower cholesterol and help in the control of blood sugar. Because of these qualities they are recommended by health organizations for the management of non-communicable diseases like diabetes and heart conditions. Pulses have also been shown to help combat obesity.

For farmers, pulses are an important crop because they can be both sold and consumed by the farmers and their families. Having the option to eat and sell the pulses they grow helps farmers maintain household food security and creates economic stability. Furthermore, the nitrogen-fixing properties of pulses improve soil fertility, which increases and extends the productivity of the farmland. By using pulses for intercropping and cover crops, farmers can also promote farm biodiversity and soil biodiversity, while keeping harmful pests and diseases at bay.

Pulses can contribute to climate change mitigation by reducing dependence on the synthetic fertilizers used to introduce nitrogen artificially into the soil. Greenhouse gases are released during the manufacturing and application of these fertilizers, and their overuse can be detrimental to the environment. However, pulses fix atmospheric nitrogen in the soil naturally, and in some cases free soil-bound phosphorous, thus significantly decreasing the need for synthetic fertilizers.
