A study was conducted during the year 20019-2020 at Annamalai University, Annamalainagar to find out a suitable media and appropriate nutritionto increase the growth, yield and quality of Asparagusdensiflorus'sprengeri' L. as cut foliage. The experiment was laid out in randomized block design with 8 treatments and 3 replications.Among the different treatments, the treatment T9 (2 parts of garden soil + 1 part of farmyard manure, decomposed coirpith and pressmud + 19:19:19 NPK complex fertilizer

Control recorded the minimumgrowth, yield and quality attributes of asparagus.
