NATURAL AND SAFE SOLUTION FOR
RICE YIELD INCREMENT
CONCEPTION
Rice is important staple food for more than 60% world's population. The rice demand is tend to increase.
Rice demand for Indonesia annually is 34 million tonnes. About 2.5 million tonnes are imported from other country.
Rice productivity for Indonesia is still relativelylow : average 4.5 tonnes/ha.
Australia : 9.5 tonnes/ha.
Japan : 6.65 tonnes/ha
Factors involving in the low rice productivity
- Consecutive rice production system all the year : The law of diminishing return.
- Imbalance use of fertilizers (mainly rely on the use of synthetic chemical fertilizers).
- Pest and diseases : brown plant hopper, tungro disease and rice blast disease.
Causal agent of rice blast
Pyricularia oryzae
Screening for antagonists from rice rhizosphere
Isolates of Rhizobacteria isolated from
plants of Graminae, and Leguninoceae
Screening for plant growth promotion by rhizobacteria formulation (Sunland)
The formation of lateral roots and root hairs in rice seedling treated with rhizobacteria formulation significantly higher when compared to control
Abundant lateral roots are formed on rice treated with rhizocabteria formulation
Comparison of rice growth with and without Sunland treatment
Treatment with rhizobacteria formulation increased the root weight by 278.6%-511%,
Comparison of rice yield with and without rhizobacteria formulation treatment.
These treatments increased the yield by 112.76%-150.91%.
-
For Seed treatment :
1 part of Sunland + 29 parts of clean water.
Soak the germinated seed for 2 hours before sowing. -
For foliar or soil treatment :
1 part of Sunland + 49 parts of clean water
Through spraying or soil dressing
Field experiment at seedling stage : Rice cultivar "Cigeulis", 17 days after sowing. Seedlings treated with Sunland showed significant better roots and shoots growth
