Quality of Growth Media and Yields of Allium ascolanicum L. on Ultisol Soil Combined with Rabbit Manure

Abstract

Onion cultivation in pots is a solution of limited land in urban areas. Nevertheless, the onion productivity is constrained by the quality of planting media. The utilization of rabbit manure is an alternative to improve the quality of planting media. This study was aimed to determine the effect of rabbit manure level in the planting media on the growth and yield of onion, as well as the effect of rabbit manure on planting media quality. The method used was a completely randomized design with one factor and 12 replications. The treatment was rabbit manure level on growth media i.e. 0%; 25%; 50%; 75%; and 100%. Parameters measured were leaf lenght, number of leafss, diameter and weight of bulbs, pH of planting media, Cation exchange capacity (CEC), Sodium, Phosphor and Potassium. The results showed that 25%-50% rabbit manure in planting media produced the best on leaf lenght, number of leafs, diameter of bulbs, and weight of bulbs. The application of rabbit manure on ultisol soil media was able to increase pH, nitrogen, phosphorus, and cation exchange capacity, vice versa decreased the content Potassium.
