Seed Biopriming Using Rhizobacterial Isolated Mixture on Increasing Growth and Yield of Shallots (Allium ascalonicum L.)

Abstract

Shallot is very potential to be developed in Southeast Sulawesi, but its productivity is very low, so it needs technological innovation, including the use of microbes as a promoter of plant growth. This study aims to evaluate the effectiveness of shallots seed biopriming using a mixture of rhizobacterial isolates to increase the growth and yield of shallots. This research was conducted at the Experimental Garden II, Faculty of Agriculture, University of Halu Oleo. The experiment was arranged using a Randomized Block Design (RBD), consisting of 8 treatments seed biopriming using a mixture of rhizobacterial isolates, ie without rhizobacterial isolates as control, CKD061 isolate, W2R06 isolate, TWB11 isolate, CKD061+W2R06 isolate, CKD061+TWB11 isolate, W2R06+TWB11 isolate, and CKD061+TWB11+W2R06 isolate. Data were analyzed using variance analysis, followed by Honestly Significant Difference test (BNJ). The results showed that Inoculation of shallots seeds with rhizobacteria both single and mixed was more able to increase the growth and yield of shallots compared to controls. CKD061 single isolate showed better performance in increasing the growth and yield of shallots compared to other controls and isolates, but was not significantly different from mixture of CKD061 + W2R06 isolates. Increased production in the biopriming treatment of CKD061 isolates and CKD061 + W2R06 isolates respectively reached 67.69% and 53.85% compared to controls. Further testing is needed on a wider scale to get more consistent results in the field.

Sulfur-Oxidizing Bacteria From Coal Mine Enhance Sulfur Nutrition in Pigeonpea (Cajanus cajan L.)

“…S. maltophilia DRC-18-7A closely followed by S. pavanii DRC-18-7B outperformed, however, others in enhancing seed germination and vigour indices. There are many reports showing an increase in seed viability and vigour due to inoculation of PGPR in different crops like rice, maize, cocoa, etc., (Kade and Jusoff, 2013;Hanapi et al, 2014;Elekhtyar, 2015;Sutariati et al, 2021). Sulfur-oxidizing bacteria with additional PGP traits have been reported to enhance the growth of different crops like canola (Grayston and Germida, 1991) and maize (Anandham et al, 2014) as it is a constituent of amino acids like cysteine, cystine, and methionine.…”

Exploring the Probiotic and Plant Growth Promoting Potential of Endophytic Bacteria Isolated from the Vegetable Crop Bhendi Abelmoschus esculentus

“…Biopriming of seeds with endophytic microbesis considered as an alternative way of reducing the use of chemicals in agriculture (Sutariati et al, 2020). Plant associated bacteria especially endophytes offer an added advantage in plant growth promotion and disease prevention (Bennet et al, 2009).…”
