Abstract

One factor affecting productivity is the quality of seeds with good initial seed vigor indicators, but less than optimum growing environment conditions also affect seeds' growth and initial Vigor. One of the technologies that can improve it is giving priming treatment to the seeds before planting. This study aims to see the effect of priming treatment to improve the quality of Vigor and early growth of 2 composite corn varieties, namely Sukmaraga and Bisma. The research was carried out in the laboratory and the Green House, with the experimental method using a Completely Randomized Design (CRD) with each seed of the two varieties treated with Hydropriming (soaking seeds before planting) using Ion-Free Water (IFW) for 30 minutes, 12 hours, and 24 hours plus a control treatment without Priming, and priming using PGR made from sodium orthonitrifenol 0.2%, sodium 2,4-dinitrophenol 0.05% both as controls. So there are a total of 10 treatments. The results showed that priming treatment greatly influenced the germination, where all Hydropriming treatments gave average germination above 88%, significantly different from seeds without priming below 82%. The hypocotyl length ratio of Sukmaraga and Bisma corn seeds was also different from the treatment without priming. Seeds with hydropriming for 12 hours showed the best field growth percentage, reaching 96.7% (Sukmaraga variety) and 96.98% (Bisma variety).

Abstract

Nutrients are the main component in a hydroponic system. Liquid organic fertilizer has the potential to be a source of hydroponic nutrition because it can be made from agricultural waste through a fermentation process using local microorganisms. The aim of the research is to analyze articles that use the theme of liquid organic fertilizer and describe various topics that are relevant and have novelties to be developed in future research. The bibiometric analysis used in the research used the 2019-2023 literature. The data collection method uses dimensions with the keyword "liquid organic fertilizer" to obtain 500 papers published in 2019-2023. The data was sorted into 300 articles for further analysis with the help of VOSviewer 1.6.19_Mac software. The research results show that the theme of liquid organic fertilizer implemented in scientific articles has become a serious concern and has had high interest value for researchers over the last 4 years. Several new topics that need to be studied further to support the development of liquid organic fertilizer as nutrition in hydroponic systems to support sustainable agriculture include: local microorganisms (mol), biostimulants, cocopeat, chicken manure. Elsevier is a publisher in the main ranking which publishes articles and is widely cited. Keywords with different topics are needed to analyze articles to get new ideas and innovations in developing knowledge and technology that supports sustainable agriculture.
