Medicinal uses of the Asparagus Plant;

The newly formed shoots (spears), roots, and “underground stems” (rhizomes) are used to make medicine, as the shoots are mostly used as a food source.

Asparagus is used along with many fluids as “irrigation therapy“ to enhance urine output.
Asparagus is also very useful for bladder infections (urinary tract infections), joint pain, and obesity; there is no scientific evidence to support its uses.
In foods, asparagus spears are eaten as a vegetable. This will produce a pungent odor within the urine in some people.
The seed and root extracts of asparagus are utilized in alcoholic beverages
The tender shoots of Asparagus contain a white crystalline substance, ‘asparagine‘, which is used in medicine as a diuretic in cardiac dropsy and chronic gout.

Climatic Requirements for Asparagus cultivation;

Asparagus is grown in temperate and subtropical regions. It requires the mean day temperature to be up to 25 degrees Celsius, and the ideal night temperature for asparagus plants is 15 to 20 degrees Celsius. It prefers the average annual rainfall range between 600 to 1000 mm.

Soil Requirement and its Preparation for Asparagus Cultivation;

Sandy or sandy loam soils are considered the best for its cultivation. The optimum pH should be between 6 – 6.75.

Avoid the commercial cultivation of asparagus on soils heavier than sandy loams. This crop can grow well on the soil, which has a salt content too much for many other crops, but it prefers natural soils. The land should be prepared thoroughly. Perfect drainage must be adopted to control crown rot disease.

Selection of Varietes for Asparaus Cultivation;

Asparagus seeds

Asparagus varieties are mainly divided into two groups, Viz.

1)Asparagus with green-colored spears: These varieties are more popular and mainly used in the fresh market

2) Asparagus with white or light green colored – These varieties are mainly used for processing purposes.

Fruits of Asparagus

Sowing of Asparagus plant ;

Sowing Time ;

Asparagus crowns are grown from seed planted in a well-prepared nursery bed. The seed is sown during the winter and autumn seasons. In the hills, it can be sown from Marchto May, whereas in the plains it can be sown from July to November.

Seed Rate of Asparagus ;

About 3 to 4 kg of seed will be enough for one acre.

Planting of Asparagus;

A) Crown Planting Method: Generally, one-year-old crowns are recommended for planting in a permanent site. The seedlings are planted at a distance of 1.5 to 2.0 meters (row-to-row spacing) and 45 to 60 cm distance kept within the rows. The interspace can be utilized for the first two to three years by growing some intercrops.

B) Direct Seedling Method: Direct seedling prefers a soil temperature of 16 degrees Celsius for perfect germination. In this method, the seed should be sown at a distance of 5 cm apart in a row. the depth of the seed sowing should be 2 to 2.5 cm.

C) Seedling Transplant method; In this method, Seedlings can be grown in seed trays, peat pots /plastic bags

Manuring in Asparagus ;

40 kg urea, 20 kg single superphosphate, and 30 kg murate of potash per acre are the recommended fertilizer dose for this crop. This should be applied in two installments. The first dose should be applied in the early spring before the start of growth, and the second dose after the harvesting is completed.

After-care in Asparagus cultivation ;

Weeding and hoeing should be done at regular intervals during the early stages of growth. The plant should be earthed up and this method enhances the yield. Irrigation may be given during warm weather more frequently, even once a week.

Harvesting of Asparagus;

Asparagus, the root system takes many years to get fully developed; therefore, harvesting can be done on a limited basis in the first year ( 2 to 3 weeks, or 8 spears per plant).

Similarly, in the second year, harvesting should also be done on a limited basis, which means when there is a reduced size of spear we must stop the further harvesting during the second year of growth.

Recommended harvesting is done from the third year onward. It is done when the spear is about 20 cm in height, and it is harvested by cutting with a knife.
