Lucerne requires phosphorus and nitrogen at sowing to aid strong establishment. Single super phosphate at 250-300 kg/ha or M.A.P or D.A.P fertiliser at 80-100 kg/ha is recommended to be drilled with the seed.
What is the amount of NPK required by Lucerne?
Apply the full dose NPK of 25 : 120 : 40 basally before sowing. Mark lines to a depth of 5 cm and 25 cm apart. Place the fertilizer mixture at a depth of 5 cm along the lines and cover the lines upto 2 cm from the top before sowing.
Does lucerne fix nitrogen?
Once nodulated, lucerne can fix nitrogen – that is, it can convert atmospheric nitrogen to a form available to the plant with the aid of rhizobium bacteria. This nitrogen allows the plant to maintain high protein levels and build up soil nitrogen.
How many tons is a hectare of lucerne?
Yields also depend on the plant population, maintenance of the crop and the variety that has been cultivated. Average yield ranges between 15 000 kg to 30 000 kg per hectare. The first cutting gives an average yield of about 1.5-2 tons/ha. and then the yield increases during subsequent cuttings.

What is lucerne fodder?
Lucerne also known as “alfalfa” or “rijka” in northen India is a protein rich fodder and considered as “queen of fodder crop”. It is a perennial plant and can supply fodder for 3-4 year in same growing. Along with protein, it is also major source of mineral and calcium.
How do you grow lucerne crops?
Lucerne does not establish well from being sown too deep. The seed should be covered by 1-2 cm of soil. Using a roller after sowing is important to get good seed soil contact on lighter soils. Treating lucerne seed is recommended in any situation for successful establishment.
What is the seed rate of lucerne?
Lucerne variety Anand-2 and SS-627 should be sown by line sowing at the seed rate of 10 kg/ha for obtaining higher forage yield and net realization.
How do you grow lucerne hedges?
Preparatory cultivation: Plough 2 to 3 times to obtain a good tilth and form ridges and furrows 50 cm apart. Water management: Immediately after planting and life irrigation on 3rd day. Then once in 10 days depending on soil type. Harvest: First harvest at 90 days after planting and subsequent harvests once in 50 days.
What is MAP Fertiliser?
Mono ammonium phosphate (MAP) is a widely used source of phosphorus (P) and nitrogen (N). It’s made of two constituents common in the fertiliser industry and contains the most phosphorus of any common solid fertiliser. MAP has been an important granular fertiliser for many years.
Does Lucerne need potassium?
Lucerne, like other legumes, has a high phosphate and potash requirement, with 10 kg of phosphate and 30 kg of potash removed for each 3 tonnes of fresh weight silage (or 1 tonne of dry matter).
What is in potash?
Potash is the common name given to a group of minerals and chemicals that contain potassium (chemical symbol K), which is a basic nutrient for plants and an important ingredient in fertilizer. Most potash is produced as potassium chloride (KCl).
How do you treat potassium deficiency in soil?
Solutions. To correct a deficiency, spread organic mulch beneath plants and apply potassium fertilizer, preferably slow-release forms such as potassium silicate or sulfur- or polymer-coated potassium products. Potassium sulfate may be used, and potassium will be held by organic matter and clay particles.
What causes potassium deficiency in soil?
Potassium deficiency can be caused by soil pH, extreme liming or calcium rich areas of fields, lack of soil oxygen or true soil deficiency. Foliar application of potassium can help in cases where deficiencies are caused by reasons other than true soil deficiency.
When should you plant lucerne?
Lucerne is usually planted in autumn (irrigated lucerne may also be planted in spring) when there is sufficient soil moisture and soil temperatures are warm enough. Seeding rate will depend on expected productivity and end use of the lucerne.
What is lucerne silage?
As a forage crop, alfalfa has high palatability, high protein levels, good winter hardiness and good drought tolerance. However, this nutritional value comes with a price. Alfalfa requires well-drained soils with high fertility and pH.
Can you direct drill lucerne?
As Lucerne is a small seed it is best to sow at a shallow depth – either drilled close to the surface or dropped onto the soil. It should be covered with a roller or very light covering chain or mesh. Lucerne will not survive if drilled at below 25 mm. Weed and Pest control at establishment.
How do you grow lucerne in NSW?
For good persistence it must be grazed or cut on rotation. Can dry out soil profiles to depth. Usually sown in autumn or in spring (irrigated) when the soil temperature is high enough and there is sufficient moisture for establishment.
What is lucerne hay made of?
Lucerne (or alfalfa) hay is made from the lucerne plant (Medicago sativa), a leguminous temperate perennial plant. Lucerne hay, when it is produced and stored correctly is commonly green in colour and should, on closer inspection contain a high percentage of leaf material and fine stems.
What is the difference between pasture and forage crops?
Meaning of Pasture and Forage Crops – A pasture is an area of land on which grasses and legumes (forages) grow for animals to graze. Forage crops are plants cultivated for their vegetative portions in a pasture and are used either in fresh or preserved for feeding livestock such as cattle, sheep and goat.
How long does it take Lucerne to mature?
Lucerne’s extensive root system enables the crop to produce good yields even under relatively dry conditions. It’s perennial nature means that once successfully established reliable production could be expected for the following 3 to 4 years.
What height do you cut lucerne?
Cutting height should be as low as possible without damaging the crowns or new shoots. It is important however that enough stubble is left to ensure the plant-material is off the ground for aeration and to stop ground moisture moving up into the windrows. It is suggested that 7-10cm is ideal.
What is the spacing of lucerne?
In New Zealand, lucerne seed has commonly been produced in rows 9 or 18 cm apart at sowing rates of 6-12 kg/ha (Wynn-Williams & Palmer 1974). However, Dunbier et al. (1983) recommended a sowing rate of 1 kg/ha and row spacing of 75 cm, although they produced no evidence to support these recommendations.
What does lucerne mean in English?
(luːsɜːʳn ) uncountable noun. Lucerne is a plant that is grown for animals to eat and in order to improve the soil. [British]regional note: in AM, use alfalfa.
Can you make silage from lucerne?
Making quality silage – High quality silage is made from high quality pasture or crop such as lucerne, which is preserved through excellent fermentation.
How do you water Lucerne?
It would be best to schedule irrigation so that the lucerne gets two equal amounts, just after cutting and again 14 days later. In winter there should be a single irrigation just after the last cut is removed, and another about 6 weeks before the beginning of the new growing season.
How much water does it take to irrigate 1 hectare?
Thus, if your rain gauge indicates that 1mm of rain has fallen, it means that 1l of water fell on every 1m2 piece of ground. There are 10 000m2 in a hectare. Therefore, if you have to irrigate 10mm/ha, you’ll need exactly 100 000l of water per hectare.
How many Litres of water does it take to irrigate an acre?
As one cubic feet of water weighs about 62.4 Ib or 28.37 kg. One cusec of water flowing for one hour is equal to 62.4 Ib X 60 X 60 = 22464 gallons, 101 tons, or one- hectare inch (28.37 liter X 60 X 60 = 101952 liters or one-acre inch.

Where is lucerne grown in South Africa?
Lucerne, a perennial summer legume, is well adapted to almost all areas of South Africa, but prefers deep, well-drained soils with a neutral to high pH.
How do lucerne grow in Kenya?
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).
What is lucerne grass?
Lucerne grows off a taproot, which stores nutrients to help the plant regrow after it has been cut or grazed. Like other legumes, such as clover, peas and beans, there are nodules on its roots, which contain nitrogen-fixing bacteria so the crop doesn’t need additional applied nitrogen (N) to grow.
How do you grow lucerne in Namibia?
PLANTING OF LUCERNE – Inoculate lucerne seeds with Nitrogen-fixing bacteria (Rhizobium) before sowing. Avoid sowing lucerne on fields with poor surface drainage and where the water table is high (0,76 m to 0,9 m of the soil surface) during most of the growing season. Avoid fields infested with perennial or noxious weeds.
