Abstract

Basal stem rot (BSR) is a serious disease of oil palm in Malaysia. It can cause damage to the root, and later cause restriction of water and nutrients supply to the aerial parts which later causes the palm to die. This study was carried out to monitor the three soil properties, namely soil moisture, electrical-conductivity (EC) and temperature taken from an inoculated and un-inoculated samples of BSR in oil palm seedling. MEC10 sensor is a sensor used in this study because it can give reading of moisture content, EC and temperature. Before it is used, laboratory work was done to see the trend of these three parameters by comparing with other equipment. This study was later conducted in a transgenic greenhouse at Institute of Plantation Studies (IKP), UPM Serdang, Selangor. Oil palm germinated seed at age 5 months were used for inoculation by using rubber wood block (RWB) method. The data collected from MEC10 sensor were taken hourly though an online system. In order to identify how fast the changes can be seen, the analysis has been done at week 3, week 7 and week 12 after plant. The results showed that samples with un-inoculated seedling gave higher reading on moisture content, electrical-conductivity and temperature compared to inoculated. Based on T-test result, soil moisture and temperature gave consistent significant different at all these weeks at 6am, 8am and 8pm; and 1-2am, 4am-2pm and 6pm and 8pm, respectively. In conclusion, the BSR in oil palm seedling can be detected as early as in week 3 after plant using moisture content and temperature value of soil.
