Abstract

One of the main food commodities in the world, including Indonesia, rice requires continuous efforts to increase productivity. The use of plant growth-promoting rhizobacteria (PGPR), which are microorganisms that function to enhance plant growth through various biological mechanisms, is one approach that is increasingly receiving attention. PGPR can accelerate flowering, increase resistance to abiotic stresses such as drought and salinity, and aid nutrient uptake, especially nitrogen and phosphorus. In addition, PGPR can reduce dependence on pesticides and chemical fertilizers and support more environmentally friendly agricultural practices. Recent studies have shown that the use of PGPR in marginal lands can increase crop yields, improve root structure, and increase water use effectiveness. In addition, the use of PGPR and seed coatings can improve germination and early plant growth. PGPR offers a sustainable solution for national food security as it has great potential to be applied to non-ideal lands such as saline soils. However, there are still problems to apply, mainly due to the growing bacterial population and varying environmental conditions. Therefore, additional research is needed to create ideal PGPR formulations and application methods to support sustainable agriculture in Indonesia.

Abstract

This study aims to analyze the early growth of rice plants (Oryza sativa L.) at the vegetative stage, which are planted in ponds as an alternative medium in Laverna, Gunungsitoli, to address the challenge of limited rice field land. The method used is descriptive quantitative, with the observed parameters including plant height, number of stems, and number of leaves measured on days 7, 15, and 22 after planting. Samples were taken from 10 plants out of a total population of 35 planting holes with 5 stems per hole. The research results show a significant increase in growth during the observation period. The height of the plants increased from an average of 12 cm on day 7 to 29 cm on day 22. The number of stems also showed growth, from an average of 2.5 stems to 2.8 stems per plant. Meanwhile, the number of leaves increased more significantly from 5 to 11 leaves. However, this growth is not without challenges, especially the attack of golden apple snails (Pomacea canaliculata) which caused some plants to lose leaves and stems, and even die in some cases. However, the growth of the plants is supported by the pond conditions that provide stable moisture, as well as the presence of microorganisms in the growing medium that contribute to nutrient availability. This study concludes that pond cultivation systems have the potential to be an efficient alternative for rice farming in terms of water usage and adaptability to climate change, provided they are accompanied by pest management and the selection of appropriate varieties. Thus, this system can be developed as a sustainable agricultural solution in areas with limited rice field land, such as coastal regions and river basins. These findings are expected to serve as a foundation for further research as well as practical guidelines for farmers and stakeholders in the agricultural sector.
