 หัวเรื่อง:ประสิทธิภาพของ EM ในการเพิ่มผลผลิตข้าว ผู้เขียน:Varaporn Komboonruang, Walaiporn Sanwong, Somsak Siripanitcharoen, Pisit Promnart สื่อสิ่งพิมพ์:pdf AbstractThe efficiency of EM on Increasing crop production was reported in many i.c. Japan. However, its information on rice yield in Thailand is limited. Therefore, there is a need to find whether EM is positively increase rice yield and should be used by farmer. The effective of EM on yield of rice was studies on three different soil types of different chemical properties at three rice research center ramely Phrase (PRE), clay loan; pH 5.8 O.M. 1.12% available P.13 mgkm-1, (Bray II), and extractable K6 mgkg-1 Prachinburi (PCR) clay soil, pH 4.12, O.M. 2.69%, available P 6 mgkm-1, and extractable K 238 mgkm-1, and Phitsanulok (PSL) clay soil, pH 5.03, O.M. 6.22% available P 20 mgkm-1, extractable K 266 mgkm-1. The experiment was conducted in cement block filled with the individual soil types varielty RD7 was employed for this study. Factoral arrangement of 23 in RCB with 6 replication was used. The treatments consisted of fumigation soil with methyl bromide and non-fumigation; with and without inorganic fertilizer and with and without application of super EM. Rice was grown to matarity and grain yield was measured. The results indicated that in low O.M. soils (PRE/PCR) EM did not appear to improved rice yield regardless of treatments. Nevertheless in high O.M. soil (soil at PSL 6.2% O.M.) application of EM slightly increase yield. In addition, EM did not decrease gall midge damage in rice yield RD7. The effect of EM was discussed in detail in the text. |
