Response, Correlation of Growth Analysis and Shallot Yield under Different Nitrogen Fertilizer Dosage and Rhizobacteria Source

Maria Theresia Darini

Background and Objective: In the rainy season farmers do not want to cultivate shallot because they are afraid of crop failure and cause low shallot production. In addition to providing high dosage of fertilizer they are also sensitive to pathogenic attacks so. This study aimed to know response and correlation between growth analysis and agronomic character in the application of Ammonium Sulphate (AS) fertilizer through the sources of Plant Growth Promoting Rhizobacteria (PGPR) on growth analysis and yield of shallot in the rainy season. Materials and Methods: The study was conducted in Sleman, special region of Yogyakarta, Indonesia from August-November, 2019. The study was done by using Randomize Completely Block Design (RCBD) factorial with three replications. The first factor was various dosages of Ammonium Sulphate (AS) fertilizer (150, 250 and 350 kg ha1). The second factor was sources of PGP rhizobacteria from bamboo, gliricidia, peanut and control which was applied by 200 kg ha1 of urea without PGPR. The observed variables were the analysis of growth and agronomic character component of shallot plant. The analyzed using analysis of variance at 5% of significant then continued by Duncan’s Multiple Range Test (DMRT) at 5% of significant, it was followed by product moment correlation formula. Results: There were not interaction between Ammonium Sulphate (AS) fertilizer dosage with PGPR sources dosage. The application of Ammonium Sulphate (AS) fertilizer dosage or PGPR source has a significant effect on growth analysis and yield. Conclusion: Cultivation of shallot was in the rainy season with application of 150 kg ha1 Ammonium Sulphate (AS) the best growth and highest yield provide on PGPR from bamboo source and higher growth and yield than control. There was a significant positive correlation between variables of growth analysis and yield of shallot bulb.
