Abstract

The experiment was the study of bio-fertilizer efficiency for rice on the

growth and yield of Sangyod rice in Phatthalung province. This experiment operated in
Moo 6, Nhakuan village, Tapan sub-district, Sribanpot district, Phatthalung province

and had been conducted from October 2017 to February 2021. The experiment

aimed to study the bio-fertillizer efficiency on Sangyod rice. It was arranged in
Randomize Complete Block Design (RCBD), consisted 8 treatments with 3 replications.

Tr.1) Control, applied 16-20-0 at the rate of 20 kg/rai combined with 46-0-0 at the rate
of 10 kg/rai, Tr.2) applied 16-20-0 at the rate of 15 kg/rai combined with 46-0-0 at the

rate of 8 kg/rai and 0-0-60 at the rate of 10 kg/rai, Tr.3) applied bio-fertilizer liquid for

rice, Tr.4) applied bio-fertilizer liquid for rice combined with 50% of chemical fertilizer
in Tr.2, Tr.5) applied bio-fertilizer liquid for rice combined with 70% of chemical

fertilizer in Tr.2, Tr.6) applied bio-fertilizer powder for rice, Tr.7) applied bio-fertilizer

powder for rice combined with 50% of chemical fertilizer in Tr.2, and Tr.8) applied bio-
fertilizer powder for rice combined with 70% of chemical fertilizer in Tr.2.

The results indicated that soil chemical properties -pH, organic matter, and

available phosphorus in soil of each treatment was statistically non-significant
difference but tended to increased. While, available potassium in soil of each

treatment was statistically non-significant difference but it tended to decreased.

Moreover, the growth (height) of Sangyod rice each treatment was statistically non-
significant difference. The yield components and yield of Sangyod rice of each

treatment was statistically non-significant difference. In addition, applied fertilizer

based on Tr.2 produced the highest number of tillers per plant (12.73 tillers per
plant) in the second year. Furthermore, it produced the highest yield in the first year

and the second year (522.37 kg/rai and 496.07 kg/rai in order) but in the third year,

applied fertilizer based on Tr.1 produced the highest yield (449.73 kg/rai)
