The Use of ZA and SP 36 Fertilizer on Growth and Yield of Red Ginger (Zingiber officinale var. Rubrum)

Abstract

Red ginger (Zingiber officinale var. rubrum) is a medicinal plant that contains essential oils in rhizome. In order to meet market demand, by integrated plant nutrition supply it is necessary to apply both organic and inorganic fertilization. This study aims to determine the right combination of ZA and SP 36 fertilizer doses in the growth and yield of red ginger. This esearch was conducted in March - August 2021 in Pelem, Wonorejo Village, Jatiyoso District, Karanganyar Regency, Indonesia with 762 usl and coordinates 7°43'24.7”S 111°05'31.2”E. The research design used randomized completed block design (RCBD) one factor with 4 levels and 6 replications. The treatment levels were D0 (Control, without in organic fertilization), D1 (225 kg.ha−1ZA+50 kg.ha−1SP 36), D2 (450 kg.ha−1ZA+100 kg.ha−1SP 36), D3 (675 kg.ha−1ZA+150 kg.ha−1SP 36). The results ZA and SP 36 fertilization obtained have not been able to increase the growth and yield of red ginger. Research needs to be done with the balance of other nutrients to increase the yield of red ginger.

The Effect of Red Ginger Essential Oil on Adherence of Streptococcus mutans

“…The highest content of essential oil from ginger is zingiberene. 23,31,32 The mechanism of action of red ginger essential oil as an antibacterial is carried out by damaging cell membranes, destroying cell membrane structures, and denaturing proteins, causing bacterial cell death. Growth metabolites such as enzymes, proteins, water, carbohydrates, and organic ions are bound by the hydrophobic compounds of red ginger essential oil so that the survival needs of bacterial cells are not met.…”

“…9,29,30 One of the most important pathogenic mechanisms of bacteria is its adherence capacity through electrostatic and chemical interactions on the surface of teeth and other bacteria in the complex extracellular matrix. 14,29,31,32 The purpose of this study is to assess the optimal concentration of red ginger essential oil for its antibacterial efficacy against Streptococcus mutans and to substantiate its effectiveness in hindering the adherence of Streptococcus mutans bacteria.…”

Mineral and Nan0-Sulfur Fertilizers Effects on the Morphological and Biochemical Components 0f the Ginger (Zingiber Officinale L.)

“…The rhizome of the red ginger plant contains numerous beneficial essential oils. Red ginger has the maximum essential oil concentration compared with elephant ginger and empiit ginger (Pertiwi et al, 2013;Setiawan et al, 2022). Ginger is a 2-to-4-feet-tall perennial with grass-like leaves up to one foot long.…”
