Scarification of seed is not required as percentage of hard seeds is very few. In monocultures, the seed rate is 12 − 20 kg/ha. Rows should be 80 − 120 cm apart with 30 − 50 cm between plants when planted with grasses, seed rate should be 5 − 8 kg/ha. It will not establish readily in the existing pastures without some form of soil disturbance. Germination is quick if seed quality is good. It is common to grow Lablab without fertilizer application. But sandy soils require application of phosphorus and sulphur and it is also beneficial if lime is applied in acid soils.

When used for forage in large areas, Lablab is often sown with annual grasses such as annual sorghums and millets and such mixtures can be strip-grazed through late summer into autumn. Light grazing to remove leaf only will prolong the productive life of Lablab pasture. In small farms, Lablab can be intercropped with maize. Lablab should be sown 28 days after the maize to avoid severe cereal crop yield depression from composition.

Companion species are sorghum (Sorghum spp) and millets (Pennisetum glaucum). Summer cereal crops are maize (Zea mays) and sorghum (S.biocolour). In Brazil, it is sown with Panicum maximum pastures. It is reported as a weed in cropped areas in some humid-tropical locations where individual plants may live upto 3 years, but no report as an environmental weed.

Seasonal yields of 2 t/ha leaf or 4 t/ha stem and leaf are common in sub-humid tropics. Dry matter yield is usually higher than for cowpea, particularly under drought conditions. For human nutrition 2 − 7 t/ha green pods. In monoculture 1-2.5 t/ha of dry matter depending on cultivar.

Lablab is highly sensitive to 2,4-D, M.C. P.A., 2,4-D-B and decamba.

Its strengths are that it is a dual purpose crop and can be used with cereals in small holder systems. Can be sown with summer grass crops to provide a mixed forage crop system. Forage quality is high. It improves the soil fertility as a green manure crop. It is drought tolerant once established. High grain yields and better resistance to root diseases than cowpea.

Its limitations are it is an annual or short-lived perennial, poor frost-resistance, host to pest attacking field beans, and indeterminate flowering, leading to extended seeding period in current cultivars.

The other advantages are that it has a considerable potential as a multipurpose legume in crop-livestock systems where rotations are possible.
