Abstract
Background: Gogo rice is a type of rice that can be cultivated on dry land with a yield productivity level of 2.57 tons / Ha. So it is necessary to make efforts to increase the growth and productivity of gogo rice through seed bio-inviguration using PGPR. The purpose of this study was to determine the effect of beni bioinviguration techniques using PGPR on the growth and productivity of gogo rice. Method: This study used a RAK consisting of 7 treatments and 5 replications. Data analysis used ANOVA at the 5% confidence level and continued with the BNT test. Result: The results showed that the use of biomatriconditioning medium integrated with PGPR could increase the stem height of upland rice by 104.2 cm, 117 cm, and 133.3, the number of tillers were 7, 13 and 15 at the age of 8, 10, and 12 MST. In addition, it can also increase the number of panicles, the length and weight of 100 grains of 14, 22.6 cm and 2.1 grams. Conclusion: the use of biomatriconditioning medium integrated with PGPR can increase the growth and productivity of gogo rice.
Highlights
Rice gogo can have a yield productivity level of 2.57 tonnes/ Ha cultivated on dry land
Result: The results showed that the use of biomatriconditioning medium integrated with Plant Growth Promoting Rhizobacteria (PGPR) could increase the stem height of upland rice by 104.2 cm, 117 cm, and 133.3, the number of tillers were 7, 13 and 15 at the age of 8, 10, and 12 MST
The results of analysis of variance (ANOVA) showed that there was an effect of seed bio-invigoration integrated with PGPR on stem height, number of tillers, number of panicles, panicle length and weight of 100 gogo rice
Summary
Rice gogo can have a yield productivity level of 2.57 tonnes/ Ha cultivated on dry land. This shows that the productivity of gogo rice production is still very low when compared to the general level of 4.76 tonnes /Ha with a population of 16 plants per m2 (Sumardi, 2017) This is due to low soil pH, aluminium poisoning, lack of calcium, magnesium and phosphorus as important elements that support the growth of rice (Dariah et al, 2014). Gogo rice is a type of rice that can be cultivated on dry land with a yield productivity level of 2.57 tons / Ha. So it is necessary to make efforts to increase the growth and productivity of gogo rice through seed bio-inviguration using PGPR. Conclusion: the use of biomatriconditioning medium integrated with PGPR can increase the growth and productivity of gogo rice
