Abstract

In Indonesia, the demand for rice always increases from year to year. However, the rice production in 2021 decreased by 0.45% more than in 2020. Therefore, production needs to be improved again to meet national food self-sufficiency. One of the innovations to increase growth is utilizing natural plant growth regulators (PGRs) derived from Allium extracts. This study aimed to find one of the best types of Allium extract that can stimulate rice growth. The study area was conducted in the greenhouse, Faculty of Agriculture, Universitas PGRI Yogyakarta, Bantul Regency, Yogyakarta Special Region, Indonesia. The research was a single factor arranged in a complete randomized design (CRD) and three replications. The treatments involved four allium species i.e., control (without treatment), shallot (Allium ascalonicum L.), garlic (Allium sativum L.), and onion (Allium cepa L.). Each type of Allium extract was used at a concentration of 20%. The research results showed that the Allium extract types significantly affected seedling growth, especially seedling height for the first time. The shallot and garlic extracts decreased seedling dry weight. The Allium extract types can stimulate shoot dry weight clump-1. Application of shallot extract could cause the highest grain dry weight clump-1. The study findings show that shallot and garlic extracts harm seed germination and seedling growth, but the onion extract does not. However, shallot is a type of Allium whose extract can stimulate rice growth. Therefore, we recommend the shallot extract type for stimulating growth in rice cultivation.
