Abstract
A study on the effects of bio-fertilizer to increase growth and rice (Ko Kho 41) yield. The
experiment was conducted on Uttaradit Soil series (Utt) clay soil, at Muang District, Phitsanulok
Province during 2017 to 2020 and Randomized Complete Block Design with 3 replications was
used. 8 treatments application i.e. 1) Control (0-0-0) 2) Application fertilizer base on soil analysis
(6-3-6 kg/rai of N-P2O5-K2O) 3) Application Bio-fertilizer 4) Application fertilizer base on 50% soil
analysis and bio-fertilizer 5) Application fertilizer base on 70% soil analysis and bio-fertilizer 6)
Application Powder Organic Fertilizer 7) Application fertilizer base on 50% soil analysis and Powder
Organic Fertilizer 8) Application fertilizer base on 70% soil analysis and Powder Organic Fertilizer.
Results showed good yield on Bio-fertilizer and Powder Organic Fertilizer treatment. They
could help to increase yield on low fertilizer apply. And rice response to Bio-fertilizer better than
Powder Organic Fertilizer.
Keywords: bio-fertilizer, Uttaradit Soil series, soil analysis, Powder Organic Fertilizer
