Synergistic effects of biochar and peat moss on growth of choy sam (Brassica Rapa L.)

Asilah Abdul Mutalib

Abstract

An experiment was carried out to determine the synergistic effects of biochar and peat moss on growth and soil-plant interaction of choy sam. It was implemented at the Soil Science Laboratory, Sultan Idris Education University. The plants were treated with different amount of biochar (0g and 20g) and peat moss (0g and 20g). Parameters of the sample such as root and shoot length, plant biomass, soil pH and soil moisture content were analysed after 44 days of transplanting. Total of experimental units were 20 pots. The experimental design used in this experiment was Randomised Complete Block Design (RCBD). Data were analysed by using Analysis of Variance (ANOVA) (SAS University Edition) and means were compared using Duncan’s Multiple Range Test (DMRT) with significance level (P ). Results in the experiment showed that soil amendment with biochar and peat moss applications did not affect any growth parameter studied such as root and shoot length, plant biomass, soil pH and soil moisture content.
