Cultivation:

The plant comes up well under a wide range of tropical and subtropical climate. Fertile moist sandy loam soils are ideal for its cultivation though it grows in a wide range of soils. Better root development is observed in soils in increased proportion of sand. However, a decline in the yield of the crop is noticed in soils containing previous years residue of the roots. Asparagus plant is best grown from its tuberous roots even though it can be successfully propagated through seeds. Since root tubers are of commercial value seed propagation provides economic advantage to the farmers. Seeds usually start germinating after 40 days and average germination is 70% (Tewari and Misra, 1996).

For the cultivation of the crop, the land is ploughed well with pre-monsoon showers and seed nurseries are raised on seed beds of approximately 1m width, 15cm height and suitable length. Seed nursery should be irrigated regularly and kept weed free. With the onset of monsoon in June-July the main field is ploughed thoroughly and pits of size 30cm cube are dug at a spacing of 60-100cm. Tiwari and Misra (1996) have reported that irrespective of more number of roots and higher fresh weight per plant under wider spacings, the per hectare yields were highest in the closer spacing of 30cm x 30cm. The pit is filled with a mixture of top soil and well decomposed FYM or compost applied at 10 - 15 t/ha and the seedlings are transplanted. Application of N, P2O5 and K2O at 60:30:30 kg/ha increases the root yield. Regular irrigation and weeding are required to realize higher yields. Standards are to be provided for training the plant (Sharma et al, 1992). Few pests and diseases are observed on this crop.

Harvesting:

Harvesting the crop after two years provided higher root yield than annual harvests in pots as well as in field experiments. Irrigating the field prior to harvest enables easy harvesting of the root tubers. The average yield is 10 - 15 t/ha of fresh root tubers though yields over 60t/ha have been reported.
