Growth and yield of shallot (Allium ascalonicum L.) on different types of media and nutrient solution on hydroponic wick system

Abstract

Effect of planting media and nutrient solutions and their interaction on growth and yield of shallot on hydroponic wick system was studied. The study was conducted in a screen house. A two factor experiment with three replications, arranged in randomized completed block design, was carried out. First factor was types of planting media i.e. sand, sand+husk charcoal (1:1), and sand+sawdust (1:1). Second factor was types of nutrient solution i.e. AB Mix, fermented urine of rabbit, and fermented vermicompost. Observed variables were plant height, leaf, tiller, and bulb number, root volume, total root length, plant fresh weight, and bulb dry weight. Data were analysed by F test followed by DMRT at a 5% error level. Results showed that shallot grown on sand+sawdust was the lowest, but types of media did not have significant effect on the other variables; plants supplied with fermented vermicompost nutrient solution had the lowest values for all observed variables. It was concluded that 50% substitution of sand with husk charcoal or sawdust did not reduce yield of shallot; solution of fermented urine of rabbit could replace solution of AB Mix, but solution of fermented vermicompost could not replace AB Mix solution for growing shallot on wick system.

Growth of Arengapinnata Seedlings on Three Different Media

“…and 15.77 cm respectively. This finding supported the finding that sawdust could be used for media of chilli [12] and shallot [13] but contrary to the finding that papaya seedling grown on sawdust+compost+soil without nutrient solution addition was the lowest [7].…”

“…High soluble tannin in the sawdusk might retard the growth of plants [5]. Soaking sawdust with water and pouring the water every day for removing the soluble tannin for 7 days resulted in that height of seedlings of pepper grown on sawdust that has been soaked for 7 days was better than that of grown on soil [13].…”
