How to grow Lucerne Grass for profit in Kenya

The Lucerne grass, commonly referred to as alfalfa, is a highly precious forage legume because of its palatable and nutritious benefits compared to Napier and other fodder.

Lucerne grass increases the quality and quantity of milk production and makes your dairy animals stronger and healthier.

Lucerne is usually mixed with silage made from green maize supplemented with concentrates for quick and visible results. Most farmers ignore this type of green gold because they think it is challenging to grow.

However, contrary to dishonest opinions, lucerne does best in all areas with good management practice.

Lucerne Grass Varieties in Kenya.

Four popular varieties of lucerne grass are grown in Kenya. These include;

  1. The Hunter river
  2. The Cuf 101
  3. Lucerne Aurora
  4. The Hairy Peruvian

The hunter river is suitable for high altitude areas, whereas the cuf 101 and the hairy Peruvian do well in lower altitudes.

All three types require the following cultivation conditions for the best results.

Soil requirement

Deep (3.5 meters depth) fertile and free-draining soils with little or no murram or small rocks is ideal for lucerne growth.

Farmers interested in growing the alfalfa grass should have their soil tested for acidity before planting.

The soil samples should be taken from the top (0-10cm) and the subsoil(30-40cm). The soil PH should be neutral up to 5.6. If the sub-soil sample has a PH of less than 5.5, it is considered too acidic and unsuitable for growing lucerne.

However, in acidic soils with a pH of less than 4.9, you should apply agricultural lime at 10 tonnes per hectare rate. Phosphates, inoculants, and liming promote root development, modulation, and nitrogen fixation.

Climatic requirement

Alfalfa grass does well in a warm and sunny climate with well-distributed rainfall of more than 1200mm annually. The grass may require supplementary irrigation under prolonged dry spells. Prolonged high humidity leads to increased pests and diseases.

How to grow Lucerne grass for profit

Seedbed preparation

Alfafa requires a fair, firm, and weed-free seedbed prepared before the onset of the rains. You should well break the subsoil with a forked jembe.

Ten tonnes of thoroughly decomposed farmyard manure should be applied and mixed well with the subsoil.

Planting

Make furrows 30-40cm apart and 2.5cm deep. Use 10-15kgs of lucerne seeds per hectare. In places where lucerne hasn’t been grown before, use lucerne inoculant, available from agrochemicals companies in Kenya.

However, in areas where inoculant is not readily available, collect soils from lucerne grown areas and mix it with the seeds before planting.

Apply Phosphatic fertilizer during planting at 40kg P2O5 per hectare. there  is no need to apply any nitrogenous fertilizer during the required period nor to maintain
Lucerne during growth.

It would help if you did hand weeding 4-6 weeks after planting, and subsequently, after that, the weed reappears.

You can also use plant extracts or organic pesticides 2-3 times to control pests. Continue applying farmyard manure to the lucerne field to improve soil fertility structure and herbage yields.

Harvesting

Lucerne grass is harvested when it starts flowering(30cm high) up to a stable height of 4.5cm from the ground level. You can obtain 6-8 cuts in a year. Never allow grazing of lucerne grass.

Farmers are encouraged to allow the alfalfa grass to wilt before feeding it to their animals, as fresh grass can cause bloating.

The excess lucerne can be conserved as hay(whole or chopped). Lucerne grass gives up to 6 tonnes of dry matter per hectare per year and 25-30% crude protein.
