Abstract
The objective of this research was to investigate efficiency of Plant Growth Promoting Rhizobacteria No.3 (PGPR–3) on yield and quality of cassava in soil series 35. The two treatments comprising of the recommend method (PGPR-3 bio-fertilizer combined with 75% chemical fertilizer according fertilizer requirement) and farmer practice were examined. Ten farmers’ farm in Mueang District and Khanu Woralaksaburi District, Kamphaeng Phet Province were participating this research during April 2022 – March 2023. The result revealed that the productivity had statistically significant difference between recommend method (average 6,640 kilograms/rai) and farmer practice (average 5,657 kilograms/rai). In term of productivity of starch, the recommend method (average 1,929 kilograms/rai) had also statistically significant difference from farmer practice (average 1,695 kilograms/rai). However, plant height at 10 months, the number of tubers per plant and the amount of starch percentage in cassava roots were not statistically significant. The results showed that the recommend method had a 4.4 percent higher production cost but a 14.3 percent increase in total income compared to the farmer's method. Consequence, BRC ratio was equally 3.7 which was higher than farmers' methods.
