Characterization, Identification, and Analysis of Plant Growth Regulator (PGR) Conditions to Four Types of Free Clean Maize

Abstract

The high price of chemical fertilizers and residues in the soil, resulting in low production of food and vegetables, biological fertilizer is believed to be able to improve and improve the availability of nutrients in the soil by utilizing existing compounds in plants in the form of PGR. Plants in general have the potential to produce various compounds, one of which is in the form of “natural PGR”. The issue now is that PGR is naturally environmentally friendly. Eco-friendly agriculture uses a lot of natural PGR. However, natural PGR is still very limited. This study aims to obtain PGR content from sweet corn, pulut corn, yellow corn, and white corn. The results showed that the highest content of auxin (IAA) was found in sweet corn PGR of 27.9303 ppm and the lowest was yellow corn PGR of 2.2689 ppm. The highest gibberellin content is found in sweet corn PGR of 442.8318 ppm and the lowest is yellow corn PGR of 74,0705 ppm. The highest content of cytokines (kinetin) is found in pulut corn PGR of 45.8963 ppm and the lowest is yellow corn PGR of 33.5830 ppm.
