Increased Growth and Production of Shallot Plant (Allium ascalonicum L) with Application of Rhizobacteria

Abstract

The low production of shallot plants in rainy season can decreased income of farmers. Thus, efforts should be made to increase production in the rainy season. The objective of this research was to know the growth and production of shallot to the application of rhizobacteria. This research was conducted from February to April 2018 at production center of Kediri Regency, East Java. Randomized Block Design with two factors was applied in this research. The First factor was a rhizobacteria that consisted of three levels: P0 (Without Pseudomonas fluorescens), P1 (Pseudomonas fluorescens with 5ml/l of concentration)and P2 (Pseudomonas fluorescens with 10 ml/l of concentration) and the second factor wasa rhizobacteria that consisted three levels: B0 (Without Bacillus subtillis), B1 (Bacillus subtillis with 5ml/l of concentration) and B2 (Bacillus subtillis with 10ml/l of concentration).The Combination treatment as nine treatments, each treatment was repeated three times to obtain 27 units of trial. Application of rhizobacteria was watered at the root with an interval of seven days. The results suggested that there were a significant difference in plant height, number of leaves, number of tubers, tuber diameter, fresh weight and dry weight of tubers between plants applied rhizobacteria and without applied rhizobacteria.
