Response of Shame Plant Root PGPR Strain To Water Shock on Shallot

Abstract

Shallot (Allium ascalonicum L.) is a type of tuber that is familiar to the Indonesian people because of its distinctive properties, taste, and aroma. however, in 2023 production declined in Banten Province. Factors causing are erratic climate and insufficient nutrient fulfillment. One of the efforts that can be made is the use of organic fertilizers such as Plant Growth Promoting Rhizobacteria (PGPR) based on mimosa roots. This study aims to determine the response of shame plant root PGPR to water stress in shallots (Allium ascalonicum L.) variety Bima Brebes. The research method used is a group randomized design consisting of two factors, namely the concentration of PGPR shame plant root and watering interval. The first factor is the concentration of PGPR shame plant root which consists of four concentrations, namely 0ml/L, 12.5ml/L, 25ml/L, and 37.5ml/L. The second factor is the watering interval which consists of three intervals, namely once a day, 1 day 2 times, and every 2 days. The results showed that the concentration of PGPR of shame plant root at 37.5 ml/L gave the best effect on the parameters of plant height, root length, and tuber wet weight. At a watering interval of 2 days, the best effect was on the number of tillers per clump and tuber wet weight. There was no interaction between PGPR concentration of shame plant root and watering interval on plant height, number of leaves per clump, number of tillers per clump, root length, tuber wet weight, and tuber dry weight.
