Stimulate The Growth of Rice Using Endophytic Bacteria from Lowland Rice Plant Tissue

Abstract

Exploration and selection of endophytic bacteria from healthy food crops grown in lowland ecosystem is important to be conducted in order to get growth-stimulating endophytic bacteria at soil with low fertility level so that capable to optimize initial growth of food crops and subsequently can increase productivity level of lowland soil.The research objective was to isolate and to test the IAA-producing endophytic bacteria isolate in stimulating the rice crop growth at lowland area. Endophytic bacteria are isolated from tissues of rice, corn and peanut crops which grown at shallow swamp land in OganIlir and OganKomeringIlir Districts, South Sumatra, Indonesia. There was nine isolates of nitrogen-fixer endophytic bacteria that capable to contribute IAA phytohormone into their growth media. The P31 isolate from rice crop tisssue of 2 months old produce the best rice sprouts than other isolates. This isolate can contribute of about 10 mg kg -1 IAA to its growth medium and increase the crownsdry weight and the roots dry weight respectively with magnitudes of 133% and 225% compared to control treatment. Concentration and absorbtion of N for rice crops innoculated with P31 isolates had increased by 169% and 400%, recpectively. The P31 isolates had been identified as Burkholderiapseudomallei (also known as Pseudomonas pseudomallei).

“…Narasumber juga menyampaikan beberapa pengalaman dalam membuat pupuk organik padat dan cair. Nara sumber juga telah mencoba penggunaan pupuk organik hayati ini pada beberapa tanaman seperti padi, jagung hibrida, jagung manis, kedelai, kacang tanah, bawang merah di lahan lebak, pasang surut dan kering (Marlina et al, 2014, 2016, 2017b, 2018a, 2018b, 2019a, 2019bdan 2020, Aminah et al, 2014, Gofar et al, 2015…”
