Abstract

The current study was aimed to determine the effect of ameliorant on Pak choi (Brassica rapa chinensis) productivity, CO₂ emissions, and factors affecting the rate of CO₂ emission. The study was carried out using a non-factorial completely randomized design with seven treatments. The imposed treatment are without ameliorant (control), 10, 20, 30 ton ha^-1 chicken manure, 4 ton ha^-1 Dolomite + Chicken Manure @ 10 ton ha^-1, Dolomite 4 ton ha^-1 + Chicken Manure @ 20 ton ha^-1 and Dolomite 4 ton ha^-1 + Chicken Manure @ 30 ton ha^-1. The variables observed are the chemical properties of peat soil, fresh and dry weight of pak choi, CO₂ emissions, and factors that affect CO₂ emissions. The results of the study revealed that the combination of Dolomite and chicken manure has a significant effect on the studied parameters and the combination of 4 ton ha^-1 dolomite + 30 ton ha^-1 chicken manure had the highest pH change (average of 6.36), highest productivity, and CO₂emission (344.42 mg cm^-2hr^-1). Results of the study can be concluded that Dolomite and chicken manure has a significant effect on the various growth parameters of B. rapa chinensis and the properties of the peat soil.
