Rico, Cyren Mendoza,Bhuiyan, Mohammad Kamrul Islam,Mintah, Lemuel O.,Shin, Dong-Il,Chung, Il-Kyung,Son, Tae-Kwon,Lee, Sang-Chul The Korean Society of Crop Science 2007 Korean journal of crop science Vol.52 No.3
The effect of biofertilizer in enhancing nutrient quality and antioxidant property of rice grain was investigated. The experiment was carried out in a randomized complete block design with 3 replications and 7 treatments namely : RF = $N-P_2O_5-K_2O(11-5.5-4.8kg\;10a^{-1});$ half of the recommended fertilizer rate, $HRF=N-P_2O_5-K_2O(5.5-2.75-2.4kg\;10a^{-1}):$ HRF+Bio 250=HRF combined with 250 kg Biofertilizer 10 $a^{-1}$; HRF+Bio 500=HRF combined with 500 kg Biofertilizer 10 $a^{-1};$ Bio 250=250 kg Biofertilizer 10 $a^{-1};$ Bio 500=500 kg Biofertilizer 10 $a^{-1};$ and NF=No Fertilizer. Results showed that HRF+Bio 500 obtained a significantly higher protein content but a significantly lower amylose content compared with RF and NF treatments. Highest phytic acid content was recorded in NF treatment while the lowest was observed in HRF+500 treatment. The highest values in both electron donating ability and reducing power were obtained in HRF+Bio 500 treatment. All treatments obtained higher reducing power than that of the RF treatment and that NF treatment showed comparable values in both electron donating ability and reducing power with those of the treated plots. Highest antimutagenicity property was also observed in HRF+Bio 500 treatment followed by Bio 500 treatment. This study showed the possibility of using biofertilizer to enhance nutritional quality and antioxidant property of rice.

Effects of Biofertilizer Rate and Application Time on Growth Characters and Grain Quality of Rice

A field experiment was conducted to investigate effects of application time and rate of biofertilizer alone and in combination with chemical NPK fertilizer on growth, yield and quality of rice. The biofertilizer used composted food waste as substrate and added with effective microorganism. The treatments included recommended NPK fertilizer(RF, $11-5.5-4.8kg\;10a^{-1}$), half recommended NPK fertilizer(HRF, $5.5-2.8-2.4kg\;10a^{-1}$), half recommended NPK fertilizer plus $250kg\;10a^{-1}$ biofertilizer(HRF+Bio 250) and $500kg\;10a^{-1}$ biofertilizer(HRF+Bio 500). The biofertilizer treatments were applied at 0, 5 and 10 days before transplanting(DBT). Grain yield of HRF+Bio 250 at 5 DBT($648.4kg\;10a^{-1}$) was statistically similar to the highest obtained in the RF($654.1kg\;10a^{-1}$). Tiller numbers at HRF plus biofertilizer treatments were already high during the maximum tillering stage, and were similar with that of the RF and higher than that of the HRF during heading stage. Likewise, ripening ratio at HRF plus biofertilizer treatments was similar with that of the RF and higher than that of the HRF. Furthermore, all the biofertilizer treatments improved protein content but reduced the amylose content and palatability compared to treatments with chemical NPK fertilizer alone. Thus, HRF+Bio 250 at 5 DBT can be used to save 50% chemical NPK fertilizer and at the same time obtain an improved rice grain yield and quality.

The biofertilizer used composted food waste as substrate and added with effective microorganism. The treatments included recommended NPK fertilizer(RF, 11-5.5-4.8kg~;10a-1 ), half recommended NPK fertilizer(HRF, 5.5-2.8-2.4kg~;10a-1 ), half recommended NPK fertilizer plus 250kg~;10a-1 biofertilizer(HRF+Bio 250) and 500kg~;10a-1 biofertilizer(HRF+Bio 500). The biofertilizer treatments were applied at 0, 5 and 10 days before transplanting(DBT).

The effects of self-incompatibility control substance (SICS) on self-pollination, fruit set, fruit weight, and seed number of pear cultivars ‘Manpung’, ‘Wonhwang’, and ‘Niitaka’ were investigated. SICS at 1 or 2 mLㆍL?¹ was sprayed at 1 day before (BHP) or after hand pollination (AHP), BHP using reduced pollen volume (BHPR), and 1 day before (BFB), during (DFB), and 1 day after full bloom (AFB). Untreated and hand pollinated (HP) trees DFB were used as control treatments. All hand pollinations were done DFB. Simple sequence repeat (SSR) gene analysis of ‘Niitaka’ seeds was conducted to determine the effect of SICS on self-pollination. Results showed that SICS applied BHP or AHP did not induce higher fruit set than HP. Only in ‘Niitaka’, SICS at 1 mLㆍL?¹ applied BHPR induced higher fruit set than HP. All SICS at 1 or 2 mLㆍL?¹ applied BFB in ‘Manpung’, and BFB and AFB in ‘Wonhwang’ yielded higher fruit set than HP, but when applied at different blooming stages in ‘Niitaka’, no treatment induced higher fruit set than HP. SICS treated trees induced higher fruit set than untreated control, and SICS applied BHP, BFB, and DFB always performed better than that applied AHP or AFB. There was no general trend on the effects on number of seeds and fruit weight. SSR gene analysis revealed that SICS promoted self-pollination at 2 mLㆍL?¹ applied DFB and at 1 mLㆍL?¹ applied BHP.
