Abstract

Soil salinity is a limiting factor in agricultural productivity. One of the biological approaches to mitigate the impact of salt stress on plants is inoculating plant growth-promoting rhizobacteria (PGPR) to the plant roots. This study aimed to investigate the eff of PGPR dosage on the growth and yield of shallots at various salinity levels. This study was carried out in the experimental field of Poncokusumo, Malang. The treatments tested consisted of two factors. The first factor was soil salinity level, consisting of four levels: no salinity, NaCl 50 mM, NaCl 100 mM, and NaCl 150 mM. The second factor was PGPR concentration, consisting of four levels: no PGPR, PGPR 10 mL/L, PGPR 20 mL/L, and PGPR 30 mL/L. The sixteen treatment combinations were arranged in a randomized block design with three replications. The data obtained were subjected to the analysis of variance (ANOVA) at a significance level limit of 5%, followed by the Honestly Significant Difference (HSD) test at a 5% significance level for any significant differences. The results showed that the application of 30 mL/L of PGPR reduced EC of the soil and improved plant height, plant dry weight, leaf area, bulb diameter, bulb weight, and the number of bulbs per plant by 33%, 47.3%, 81%, 13%, 34.2%, 98.5%, and 31%, respectively, compared to the treatment without PGPR application under NaCl 150 mM salinity. The application of PGPR at 20 and 30 mL/L dosages significantly increased chlorophyll, flavonoid, and proline indices at NaCl at 100 mM and 150 mM salinity levels compared to the treatment without PGPR.

Abstract

Shallot (Allium cepa L.) is an annual Liliaceae family plant and a major horticultural commodity globally. As a crucial horticultural product, market demand for shallots tends to increase. However, global climate change causes saline land areas to increase. Salt stress is one of the leading challenges limiting yield worldwide. This study aims to understand the impact of salt stress on the growth of shallots and their stress tolerance limits. This research was conducted from August to October 2023 in Wonorejo Village, Poncokusumo District, Malang Regency. The plant material used in this study was the Tajuk variety of shallots. This study used a Randomized Block Design (RBD) with four salinity treatments ( 0, 100, 150, and 200 mM NaCl), each replicated three times. Variables observed in this study include plant length, leaf number hill-1, tiller number hill-1, and plant fresh weight hill-1 that were observed at 2, 4, 6, and 8 weeks after planting (WAP). Our results showed that plants treated with 100 mM NaCl decreased plant length, leaves number, tiller number, and plant fresh weight (shoots, roots, and bulbs) by 8 %, 10 %, 8 %, and 12 %, respectively. While at a concentration of 150 mM, the reduction was 14 %, 30 %, 18 %, and 22 %. Furthermore, the highest percentages of decrease of those growth variables, up to 27 %, 42 %, 31 %, and 41 %, respectively, were obtained at 200 mM treatment. These findings may help to understand the morphological and ecological aspects of salt stress in plants and how plants grow and develop under salinity conditions. This study also highlights the importance of further studies on the physiological of shallot on salt stress. This might result in innovative strategies and technology that crops' resilience to salinity, and ensure food security and the sustainability of farming in impacted areas Keywords: shallot, abiotic stress, salinity, plant growth.
