Abstract

Production area of some vegetables has been shifting from highland to lowland due to the decline of acreage. The main problems of growing shallot on ultisol Bengkulu are low soil pH and reduction of organic matter. The purpose of this study was to evaluate the shallot performance and yield after the application of dolomite and chicken manure. The study was conducted on the experimental field of the Faculty of Agriculture, University of Bengkulu from November 2018 to January 2019. Completely Randomized Design (CRD) was set in two factors and three replications. The factor of dosage of chicken manure consisted of four levels, they were 0 tons / ha, 10 tons / ha, 20 tons / ha, and 30 tons / ha. The other factor was the dosage of dolomite, based on exchangeable Aluminium (Al-ex), which consisted of four dosage levels e.i.: 0 Al-ex, 0.5 x Al-ex, 1 x Al-ex, and 1.5 x Al-ex. Dosage of chicken manure and dolomite influenced tuber weight and tuber diameter. The dosage of 30 ton/ha of chicken manure and 1x Al-ex (3 ton/ha of dolomite) resulted in 7.40 g for tuber weight and 23.24 mm for tuber diameter. Addition of dolomite and chicken manure into Ultisol increased pH and lowered exchangeable Al. There is an indication that high dose application of chicken manure should be paired with lower dose of dolomite to enhance tuber growth of shallot. As single factor, both treatments had affected plant height, time to harvest, fresh weight, dry weight. The higher the dose of dolomite or chicken manure, the longer the days to harvest time.
