 หัวเรื่อง:ผลของ EM ต่อการเจริญเติบโตบักเตรีอิสระที่สามารถตรึงไนโตรเจน ผู้เขียน: บรรหาญ แตงฉ่ำ, Sompron Choonluchanon สื่อสิ่งพิมพ์:pdf AbstractN2-fixing bacteria, Azotobacter sp. and Azospirillum brasilense were cultured on Brown’s medium (1968) and Dobereiner’s medium (1976) with 1% super EM and without super EM, respectively to evaluate the effect of super EM on the growth of the bacteria, Results found that, the growth of Azotobacter sp grown on Brown’s medium with and without super EM was not significant difference. Reduction of the population growth of Azospirillum brasilense was found when it was grown on Dobereiner’s medium with 1% super EM. More over, contamination existed on the medium with super EM causing inhibitive effect of A. brasilelnse growth. |
หัวเรื่อง:ผลของสาร EM ต่อการเจริญเติบโตและการตรึงไนโตรเจนของสาหร่ายสีเขียวแกมน้ำเงิน ผู้เขียน:Sompron Choonluchanon, บรรหาญ แตงฉ่ำ, Jirayuth Tunveenukul สื่อสิ่งพิมพ์:pdf AbstractEffective Microorganism or EM is widely distributed to the farmers with diversity application purposes. The experiment was conducted at Soil Microbiology Research Group. Division of Soil Science to obtain the effect of EM on the growth and nitrogen fixation efficiency of Blue Green Algae (BGA). Five species of BGA, Nostoc sp., Calothrix sp., Tolypothrix sp., A. siamensis and A. royzae were cultured in N-free nutrient solution (BG11) containing EM at the concentration of 0, 150, 300 and 600 ppm, respectively. Dry biomass, ARA and chlorophyll content were estimated as growth and nitrogen fixing efficiency parameter of BGA. Results found that the growth and nitrogen fixation of BGA in EM solution at the concentrations of 150 and 300 ppm were better than control. The growth reduction was found at the concentration of EM upper than 300 ppm. |
หัวเรื่อง:ผลของ EM ต่อการเจริญเติบโตและผลผลิตของข้าว ข้าวโพด และข้าวฟ่างในแปลงทดลอง ผู้เขียน:บรรหาญ แตงฉ่ำ, Sompron Choonluchanon สื่อสิ่งพิมพ์:pdf AbstractThe effect of EM on the growth and yield of rice, corn and sorghum were studied in field condition at Udonthani Rice Experiment Station, Chainat Field Crop Research Center and Supanburi Field Crop Research Center for corn and sorghum. The experimental design was randomize complete block with 3 treatments; check, EM and N-P-K, and 4 replication. The EM treatment were the application of 5 litters of EM solution per 30 m2 area (EM solution was mixture of EM: molasses: water = 1:1:500 by volume) for corn and sorghum and 2.5 liters/25 m2 of EM for rice treatment. Fertilizer treatment were 5-5-5 kg/rai of N-P2O5 respectively, as basal and 5 kg-N/rai as topdressing for corn and sorghum and 3-4-2 kg/rai of N-P2O5-K2O respectively as basal and 3 kg-N/rai as topdressing for rice. Results showed that the yield of corn, sorghum and rice in EM treatment were the same as check but loneer than N-P-K treatment. |
