Abstract

Essential oils are plant natural products resulting from secondary metabolites used for raw materials of various industries such as perfumery, preservative, cosmetics, and pesticide. The major problem of essential oil plants cultivation is the low essential oil content. Enhancing essential oil content is one of the main focuses in developing essential oil plants which can be reached by water management. Growth and yield reduction and changes in some physiological reactions are the responses of a plant toward water supply shortage (water stress). Water stress triggers elicitors and some signal molecules produced for secondary metabolites resulting in higher essential oil percentages. However, it would also decrease essential oil yield following lower biomass production. Some microorganisms can produce phytohormone and enhance nutrient uptake allowing the plant to cope under water stress condition.  Understanding how the environment affected plant secondary metabolite (especially essential oil), as well as microorganism roles for crop production, will provide proper cultivation technology to increase plant essential oil content and oil yield. This review aimed to analyze the potential use of some biological agents to alleviate the negative effect of water stress on essential oil plants.ABSTRAKMinyak atsiri merupakan produk alami tanaman dari hasil metabolisme sekunder yang digunakan sebagai bahan baku berbagai industri seperti parfum, antiseptik, kosmetik, dan pestisida. Budidaya tanaman  minyak atsiri menghadapi kendala seperti rendahnya kandungan minyak yang dihasilkan. Pertumbuhan dan penurunan hasil serta perubahan pada beberapa reaksi fisiologis merupakan respon tanaman terhadap cekaman air. Cekaman air memicu produksi elisitor dan beberapa molekul sinyal pada metabolit sekunder sehingga dapat menghasilkan minyak atsiri yang lebih tinggi, akan tetapi tidak diikuti dengan peningkatan produksi biomassa sehingga produksi minyak atsiri tidak cukup tinggi. Beberapa mikroorganisme mampu menghasilkan fitohormon dan meningkatkan serapan hara yang memungkinkan tanaman dapat bertahan pada kondisi cekaman air. Pemahaman bagaimana lingkungan dapat mempengaruhi metabolit sekunder dari tanaman (khususnya minyak atsiri), serta peran mikroorganisme terhadap produksi tanaman, akan menghasilkan teknologi budidaya yang sesuai untuk meningkatkan kandungan dan hasil minyak atsiri suatu tanaman.  Review ini bertujuan menganalisa potensi penggunaan beberapa jenis agens hayati untuk mengurangi dampak negatif dari cekaman air pada tanaman penghasil minyak atsiri.

Abstract

This study aimed to screen and characterize halotolerant bacterial isolates, which could enhance plant growth performance in saline soil. Halotolerant bacteria was isolated from weeds rhizosphere grown in saline soil of coastal agricultural land located at Brondong District, Lamongan Regency, East Java Province, Indonesia. This research was conducted from June to September 2018. Seven bacterial isolates can grow in a Nutrient Agar medium containing 10% of NaCl, suggesting that these bacteria were halotolerant. Furthermore, all bacterial isolates were shown to produce indol acetic acid (IAA) and do not induce a hypersensitive response when infiltrated into tobacco leaves. These results explain that these bacteria had potency as plant growth-promoting rhizobacteria (PGPR) and were not tend to be the plant pathogen. The growth of seedlings when inoculated in cucumber seed grown in saline media were higher than those in control. This result suggests that the halotolerant bacteria can enhance the development of cucumber seedlings in saline stress conditions. Three potential halotolerant bacteria i.e., SN22, SN23, SN26 were selected and molecularly identified as Bacillus megaterium, Bacillus sp., and B. megaterium, respectively.

Abstract

Combining the application of organic manure with inorganic fertilizer treatment can improve the productivity of the cucumber. Biogas slurry is synthesized from organic manure that can improve soil fertility and increase the yield of cucumber. This research aimed to learn the effect of biogas slurry and inorganic fertilizer on soil fertility and its impact on yield of cucumber and to learn the role of biogas slurry in decreasing amount of inorganic fertilizer used on the crop. This research was conducted in former paddy field located in Wriginsongo village, District of Tumpang, Malang Regency from March to May 2017. A randomized block design factorial was used with biogas slurry treatment as the main plot which consists of three levels: 10 t ha-1, 20 t ha-1, and 30 t ha-1while the subplot was the dosages of inorganic fertilizer which consists of100%,75%and 50% dosage of recommendation. This research revealed that biogas slurry treatment could increase the organic matter on the plant. There were some interactions between biogas slurry and inorganic fertilizer in the number of fruits produced, the weight of the fruit, the total weight of fruit produced per plant and hectare. Biogas slurry improved organic matter from 0.29% to 2.06%, N total from 0.06% to 0.15%, P2O5 from 93.48 ppm to 224.31 ppm, K2O from 2.01me 100 g-1 to 100 me 100 g-1, and C/N ratio from 3 to 9.

Abstract

Cutleaf groundcherry is a medicinal herbaceous plant that has not been widely cultivated. Adjustment to the light intensities supported by the fulfillment of essential macro-nutrient underlies the agronomic consideration for cropping system determination. The study aimed to examine the growth and yield of cutleaf groundcherry grown under shade nets of various shading percentages and potassium application at different dosages. A split-plot design was used for this pot experiment repeated three times. The main plot was the shading percentages (0, 25, 50 and 75), while potassium dosages (0, 60, 120 and 180 kg ha-1) were the subplot. The result showed that several growth variables were affected by the interaction between shading percentages and potassium dosage, whereas yield variables were not. Under the high level of shading, leaf number (41% to 50%), leaf area (28% to 50%), and shoot dry weight (70% to 85%) were reduced at all potassium dosages. Potassium dosage at 120 kg ha-1 was required to achieve better growth under full sun or soft shading. Shading at 50% and upper significantly decreased fruit production by 30% lower fruit number, 50% to 80% lower fruit weight, and 15% lower total soluble solids (TSS). In addition, potassium fertilizer at 120 kg K2O ha-1 improved fruit weight but did not affect TSS. It can be concluded that cutleaf groundcherry is able to grow well under high intensity of light and need an adequate supply of potassium to improve growth, yield and fruit quality.
