THE EFFECTS OF BIOCHAR AND RAISING MYCORRHIZA USAGE ON SEVERAL MINERAL INGREDIENT OF PAK CHOI

Abstract

This study aims to determine the effect of biochar and increasing mycorrhiza applications on some mineral material content of pak choi plant. In the beginning of the experiment, 300 g/m(2) parcel biochar was used for each parcel one month before seedling planting. Then, increasing mycorrhiza doses per plant (0, 15, 20, 30 and 40 mL) were used to the parcels undergoing biochar application and the harvest occurred 54 days after seed sowing. The findings revealed important increases in some macro and micro nutrient element contents of Pak Choi plant with biochar and increasing mycorrhiza applications. The contents were found as P (0.41 %, 0.46 %, 0.47 %, 0.49 % and 0.56 %), K (4.33 %, 4.19 %, 4.06 %, 4.17 % and 4.59 %), Ca (2.03 %, 2.24 %, 2.17 %, 2.25 % and 2.47 %), Mg (0.15 %, 0.16 %, 0.17 %, 0.17 % and 0.20 %), Fe (569 mg/kg, 973 mg/kg, 1016 mg/kg, 1016 mg/kg and 1094 mg/kg), Cu (5.02 mg/kg, 6.26 mg/kg, 6.58 mg/kg, 7.04 mg/kg and 13.16 mg/kg), Mn (62.73 mg/kg, 74.03 mg/kg, 78.00 mg/kg, 85.96 mg/kg and 114.10 mg/kg) and Zn (37.23 mg/kg, 41.36 mg/kg, 42.03 mg/kg, 43.53 mg/kg and 52.83 mg/kg), respectively. Some macro (P, K, Ca and Mg) and micro (Fe, Cu, Zn and Mn) element contents were determined statistically significant at the level of 5 %. The best nutrient element contents of pak choi plant were obtained at V. dose: 40 mL /plant mycorrhiza applications.
