Abstract

Lemongrass (Cymbopogon nardus L.) is an economically valuable plant that produces citronella oil and could grow on marginal lands. This study aimed to analyze citronella oil yields planted with agroforestry and monoculture patterns in a post-mining revegetation area. The treatment consisted of 3 factors, namely planting pattern, fertilizer dosage, and plant spacing. The measured variable was the citronella oil yield. The study was conducted by planting two lemongrass varieties i.e., Sitrona 2 Agribun Variety dan G2 Variety in the agroforestry and monoculture areas. The study was conducted for 12 months with three harvest times, i.e., in the 6th, 9th, and 12th months. The results showed that planting patterns significantly affected the citronella oil yield. Planting pattern of Monoculture-Sitrona 2 Agribun Variety (P4) produced the highest oil yield (1,95%). Plant spacing and dosage of bokashi fertilizer did not significantly affect the citronella oil yield. The Monoculture-Sitrona 2 Agribun Variety (P4) significantly increased the oil yield compared to the Agroforestry- Sitrona 2 Agribun Variety (P2), Monoculture-G2 Variety (P3), and Agroforestry-G2 Variety (P1) with a respective oil yield of 1,95% (P4), 1,50% (P2), 1,01% (P3), and 0,99% (P1). Sitrona 2 Agribun Variety tended to produce a higher oil yield than the G2 Variety. Keywords: agroforestry, citronella oil, lemongrass, oil yield, revegetation

香茅(Cymbopogon nardus L.)采煤后复垦区农林业与单一栽培模式下油料产量分析

柠檬草(Cymbopogon nardus L.)是一种生产香茅油的具有经济价值的植物，可以种植在边缘土地上。本研究的目的是分析在采伐后复植区采用农林业和单一栽培模式种植香茅油的产量。处理包括种植方式、施肥量和株距3个因素。测量变量为香茅油得率。通过在农林业和单作区种植香茅品种Sitrona 2 Agribun品种和G2品种进行研究。研究为期12个月，分为第6个月、第9个月、第12个月三个采收期。结果表明，种植方式对香茅油产量有显著影响。单栽-西rona 2型农用品种(P4)的产量最高(1.95%)。株距和施用博克施量对香茅油产量影响不显著。与农林业-Sitrona 2农业品种(P2)、单栽培- g2品种(P3)和农林业- g2品种(P1)相比，单栽培-Sitrona 2农业品种(P4)的油分产量显著提高，分别为1.95% (P4)、1.50% (P2)、1.01% (P3)和0.99% (P1)。西特罗纳2号农用品种的油料产量高于G2品种。关键词:农林业;香茅油;柠檬草

期刊介绍： The Journal of Symbolic Logic publishes research in mathematical logic and its applications of the highest quality. Papers are expected to exhibit innovation and not merely be minor variations on established work. They should also be of interest to a broad audience. JSL has been, since its establishment in 1936, the leading journal in the world devoted to mathematical logic. Its prestige derives from its longevity and from the standard of submissions -- which, combined with the standards of reviewing, all contribute to the fact that it receives more citations than any other journal in logic.
