Improvement of seed quality and organic of Brown rice productivity with matriconditioning plus biological agents in jatiluih tourism

Abstrak

Jatiluih Village is a cool, mountainous area in Penebel sub-district, Tabanan regency is a World Cultural Heritage area (World Herritage).Tthis area is visited by many foreign tourists and is one of the famous tourism areas in Bali. The tourism object in this area is the natural beauty of terraced rice paddies and in the paddy fields there are many cowshed as a source of organic fertilizer, accompanied by a strong survival system of irrigation culture called Subak.

The famous rice production in this area is brown rice, Jatiluih local brown rice is very popular with urban communities because besides it is organic, it also tastes fluffier and fragrant but if it is cooked it doesn't need to be mixed with white rice. Thus the improvement of brown rice cultivation should be carried out by involving growth-promoting  bacteria  (PGPR)  whose  application  is  to  sead  treatment  in  the proper carrier matrix, from the results of research obtained;

A matrix containing with one PGPR bacterium can increase seed germination capacity, and brown rice plant height compared to control without PGPR

Organic  fertilizer  in  the  form  of  a  matrix  containing  4  types  of  bacteria Serratia marcescens,  Achromobacter  spanius, Providencia vermicola and Myroides adoratimimus can increase seed germination by 2 times, plant height and number of plant leaves 1.5 times compared to control.

In terms of Stimulated the growth of rice plants, between the PGPR bacteria, it turns  out  that  A. spanius  and  P. vermicola  bacteria  have  a fairly  good  ability  to increase the number of tillers in rice plants by 1.5 times the control, and it is expected that later production of brown rice will increase to 1.5 times as well. Likewise, rice plants that received  PGPR bacteria  produced  higher, higher number  of leaves and chlorophyll compared to controls that did not get PGPR bacteria

In the chromatographic image the GCMS results clearly showed the content of the compounds  in the control ie plants without being given PGPR,  the number of compounds  was far less than in rice that was treated by PGPR bacteria. Rice with PGPR contains 9,12,15-Octadecatrienoic  acid which is anti-bacterial and anti-fungal, while Neophytadiene and 2-Methoxy-4-vinylphenol can increase plant growth.
