The Effect of Molybdenum Fertilizer on the Growth of Grass–Legume Mixtures Related to Symbiotic Rhizobium

Molybdenum (Mo) is required by the enzymes involved in many metabolic processes related to plant growth and development. However, the effects of Mo addition on plant growth and beneficial microorganisms in mixed grasslands are unclear. We conducted a greenhouse experiment to examine the effects of different Mo addition levels (10 and 20 mg Mo kg−1 soil in the form of Na2MoO4) on the growth of perennial ryegrass–white clover in two low-Mo soils, as well as their symbiotic microorganisms. Our results showed that the addition of Mo had a significant impact on plant growth in limestone soil but not in yellow loam soil (p < 0.05). Compared with no addition of Mo fertilizer in limestone soil, an addition of 10 mg Mo kg−1 significantly increased the plant community shoot and root biomass (p < 0.05). However, this improvement was not observed with an addition of 20 mg Mo kg−1. The shoot nitrogen and phosphorus content in both soil types was unaffected by the Mo addition (p > 0.05), whereas the 10 mg Mo kg−1 addition significantly increased the shoot nitrogen and phosphorus uptake in limestone soil (p < 0.05). This increase in plant community productivity was primarily due to the increased growth of both species, caused by the enhanced activation of the symbiotic rhizobium. We conclude that Mo supply may promote N utilization and uptake in mixed grassland by increasing the activity of symbiotic rhizobium, resulting in a higher yield of mixed grassland, which is critical for sustainable agricultural development in low-Mo soils.

Allelopathic effects of tamarind husk, lemongrass and citronella residues to suppress emergence and early growth of some weeds

The allelopathic effects were evaluated of water extracts from tamarind (Tamarindus indica L.) husk and from lemongrass (Cymbopogon citratus Stapf.) or citronella (Cymbopogon nardus Rendle.) leaves on 2 test plants: ruzi grass (Brachiaria ruziziensis Germ. & C.M. Evrard) and popping pod (Ruellia tuberosa L.). In the laboratory, the seeds were subjected to the different extracts at concentrations of 0, 1.25, 2.5, 5 and 10 % (w/v). The number of germinated seeds was counted daily for 6 days. The shoot/root length was measured 5 days after sowing (DAS). The results showed that the aqueous extract of tamarind husk did not inhibit the germination of either ruzi grass or popping pod. The lemongrass and citronella extracts had higher inhibition effects at high concentrations and clearly delayed seed germination at 10 % (w/v). With the seedling growth bioassays of the 3 extracts, only the citronella extract at the highest concentration had any effect on the shoot/root lengths of ruzi grass. Popping pod was susceptible to all 3 extracts, especially the popping pod roots treated with lemongrass and citronella extracts. The lemongrass and citronella extracts caused cell death and induced lipid peroxidation in both plants. Therefore, the primary action of these extracts on seedling growth inhibition might have been related to the loss of cell viability and triggering lipid peroxidation in affected tissues. The residue incorporation bioassay determined the effects of residue mixed in soil at concentrations of 0, 2.5, 5 and 10 % (w/w) on the growth of ruzi grass and popping pod at 30 DAS. Both plants showed an adverse effect than for the control, based on reduced leaf numbers and greater chlorosis, especially with soil incorporation of the lemongrass and citronella residues at 10 % (w/w). Mixing soil with lemongrass and citronella leaves at 2.5 % (w/w) and above resulted in reductions in the shoot/root lengths and shoot/root biomass values. Catechin, gentisic acid, syringic acids, p-coumaric acid and ferulic acid were the dominant allelochemicals found in the lemongrass and citronella residues.

Recycling eutrophic lake sediments into grass production: A four-year field experiment on agronomical and environmental implications

Inefficient use of phosphorus (P) fertilizers leads to the transfer of P into water bodies, causing their eutrophication. Sediment removal is a promising lake restoration strategy that removes nutrients including P accumulated in lake sediments, and opens the opportunity to use removed nutrients in agriculture. In the present study, we investigated the effects of using a thick layer of sediment from the eutrophic Lake Mustijärv on plant growth, and estimated the environmental impacts of different sediment application methods by analyzing greenhouse gas emissions, N and P leaching, aggregate stability, and soil biota. The field experiment (2017–2020) was established on the lake shore with the following treatments: the agricultural control soil (Soil) surrounding the lake, pure sediment (Sed), biochar-treated sediment (SB), and biochar and soil mixed with sediment (SSB). The sediment-based treatments resulted in a similar grass growth performance to the Soil. The availability of most macro- and micronutrients including P (75 vs. 21 g m−3) were far greater in the Sed compared to the Soil. The sediment-based growing media emitted more CO2 than the Soil (579 vs. 400 mg CO2 − C m−2 h−1) presumably due to the high rate of organic matter decomposition. The bacterial and fungal community structures of the Sed were strongly differentiated from those of Soil. Also, Sed had lower bacterial diversity and a higher abundance of the bacterial phyla associated with solubilizing P including Proteobacteria and Chloroflexi. Sediment-based growing media increased more than seven times the risk of mineral N and P leaching, and the biochar treatment only had a short-lived beneficial effect on reduction of the sediment's leached P concentration. The sediment application rate should be adjusted to match the crop requirements to minimize greenhouse gas emissions and nutrient leaching when upscaling the case study to larger lakes with similar sediment properties.

How Much Complexity Is Required for Modelling Grassland Production at Regional Scales?

Studies evaluating the complexity of models, which are suitable to simulate grass growth at regional scales in intensive grassland production systems are scarce. Therefore, two different grass growth models (GrasProg1.0 and APSIM) with different complexity and input requirements were compared against long-term observations from variety trials with perennial ryegrass (Lolium perenne) in Germany and Denmark. The trial sites covered a large range of environmental conditions, with annual average temperatures ranging from 5.9 to 10.3 °C, and annual rainfall from 536 to 1154 mm. The sites also varied regarding soil type, which were for modelling categorised into three different groups according to their plant available water (PAW) content: light soils with a PAW of 60 mm, medium soils with a PAW of 80 mm, and heavy soils with a PAW of 100 mm. The objective was to investigate whether the simple model performed equally well with the given low number of inputs, namely climate and PAW group. Evaluation statistics showed that both models provided satisfactory results, with root mean square errors for individual cuts ranging from 0.59 to 1.28 t dry matter ha−1. The model efficiency (Nash–Sutcliffe efficiency) for the separate cuts were also good for both models, with 81% of the sites having a positive Nash–Sutcliffe efficiency value with GrasProg1.0, and 72% with APSIM. These results reveal that without detailed site-specific descriptions, the less complex GrasProg1.0 model can be incorporated into a simple decision support tool for optimising grassland management in intensive livestock production systems.

PENGGUNAAN BERBAGAI KOMPOS KOTORAN TERNAK TERHADAP PERTUMBUHAN Pennisetum purpureum cv. Pakchong

Manure derived from cattle, chickens, and goats can be used as compost and has different nutrient content. The application of manure compost can improve soil’s physical, chemical, and biological properties and thus increase plant growth and productivity. The purpose of this study was to determine the effect of various manure compost (cow, chicken, and goat) on the growth of elephant grass cv Pakchong (Pennisetum purpureum cv. Pakchong). The design used was a completely randomized design with 4 treatments and 5 replications. The treatment is fertilizing using compost, namely P0= without compost, P1=cow manure compost, P2=chicken manure compost, and P3=goat manure compost. The observed variables were plant height, the number of leaves and tiller, and the dry weight of the leaves stem shoots and roots. The results showed that the use of manure compost had a significant effect (P<0.05) on increasing the growth of elephant grass cv. Pakchong. Chicken manure compost produces the best growth of elephant grass cv. Pakchong which is seen from the plant height, the number of leaves and tiller, and the dry weight of the leaves, stems, and shoots.

Evidence of plant-soil feedback in South Texas grasslands associated with invasive Guinea grass

Plant-soil feedback (PSF) processes play an integral role in structuring plant communities. In native grasslands, PSF has a largely negative or stabilizing effect on plant growth contributing to species coexistence and succession, but perturbations to a system can alter PSF, leading to long-term changes. Through changes to soil abiotic and biotic properties, invasion by non-native plants has a strong impact on belowground processes with broad shifts in historical PSFs. Guinea grass, Megathyrsus maximus, an emerging invasive in South Texas, can efficiently exclude native plants in part due to its fast growth rate and high biomass accumulation, but its impacts on belowground processes are unknown. Here, we provide a first look at PSF processes in South Texas savannas currently undergoing invasion by Guinea grass. In this pilot study, we addressed the question of how the presence of the invasive M. maximus may alter PSF compared to uninvaded grasslands. Under greenhouse conditions, we assessed germination and growth of Guinea grass and the seed bank in soil collected from grasslands invaded and uninvaded by Guinea grass. We found that Guinea grass grown in soil from invaded grasslands grew taller and accumulated higher biomass than in soil from uninvaded grasslands. Plants grown from the seed bank were more species rich and abundant in soil from uninvaded grasslands but had higher biomass in soil from invaded grasslands. In South Texas savannas, we found evidence to support shifts in the direction of PSF processes in the presence of Guinea grass with positive feedback processes appearing to reinforce invasion and negative feedback processes possibly contributing to species coexistence in uninvaded grasslands. Future work is needed to determine the mechanisms behind the observed shifts in PSF and further explore the role PSF has in Guinea grass invasion.

Ecosystems of Alas Landscapes—The Basis for the Development of Cattle Breeding in the Harsh Natural and Climatic Conditions of the Permafrost Zone

Alas landscapes are unique ecosystems, which are dynamic, geochemically closed thermokarst landforms of the permafrost zone. Alases have a limited capacity in their active layer, and specific conditions for soil, flora and fauna formation. A comprehensive study of alas landscape functionswas carried out in Central Yakutia from 1988 to the present time using conventional methods of geobotany, zoology, entomology, etc. This paper presents long-term observations of lake fluctuation cycles and changes in the spatial structure of meadow spaces. The dynamics of the spatial structure lead to significant fluctuations in the productivity of alas phytocenoses. It was revealed that wet and normal alas meadows have the highest vegetation productivity. The long-term course of their productivity tends to decrease, which shows the influence of anthropogenic pressure since the main haymaking areas are located in these meadows. With sharp fluctuations in interannual weather conditions, which determine the microclimatic and soil characteristics of grass growth, the productivity of the edge phytocenoses tends to increase. The productivity of the steppe phytocenoses of the alas remains practically at the same level. Over the years of observation, the economic capacity of alas pastures and hayfields was calculated. Additionally, the paper presents the important role of fauna within closed alas ecosystems, which directly affects the functioning of alas landscapes and is directly involved in soil formation and the circulation of matter and energy.

Deep mowing rather than fire restrains grassland Miscanthus growth via affecting soil nutrient loss and microbial community redistribution.

Fire and mowing are crucial drivers of grass growth. However, their effects on soil properties, microbial communities, and plant productivity in dry-alkaline grasslands have not been well investigated. This study evaluated the effects of mowing (slightly and deeply) and fire on vegetation traits (Tiller number per cluster and plant height) and biomass (plant dry weight), and soil availability of N, P, and K, as well as soil microorganism abundance in a Miscanthus system. We designed one control and three experimental grass plots (slightly and deeply mowed, and burned) in 2020-2021 in the Xi'an Botanical Garden of Shaanxi Province, Xi'an, China. Tiller number, plant height per cluster, and soil N, P, and K availability during Miscanthus growth decreased significantly (p < 0.05) in all treatments compared to the control. However, this effect was much greater in the deep-mowing plot than in the other plots. After harvest, deep mowing induced the greatest effect on biomass among all treatments, as it induced a 5.2-fold decrease in dry biomass relative to the control. In addition, both fire and mowing slightly redistributed the community and diversity of the soil bacteria and fungi. This redistribution was significantly greater in the deep-mowing plot than in other plots. In particular, relative to the control, deep mowing increased the abundance of Firmicutes and especially Proteobacteria among soil bacterial communities, but significantly (p < 0.05) decreased Basidiomycota and increased Ascomycota abundance among soil fungal communities. We conclude that nutrient limitation (N, P, and K) is crucial for Miscanthus growth in both mowing and fire grasslands, whereas deep mowing can induce soil nutrient loss and microorganism redistribution, further restraining grass sustainability in dry-alkaline grasslands.

Genome wide association analysis of root hair traits in rice reveals novel genomic regions controlling epidermal cell differentiation

BackgroundGenome wide association (GWA) studies demonstrate linkages between genetic variants and traits of interest. Here, we tested associations between single nucleotide polymorphisms (SNPs) in rice (Oryza sativa) and two root hair traits, root hair length (RHL) and root hair density (RHD). Root hairs are outgrowths of single cells on the root epidermis that aid in nutrient and water acquisition and have also served as a model system to study cell differentiation and tip growth. Using lines from the Rice Diversity Panel-1, we explored the diversity of root hair length and density across four subpopulations of rice (aus, indica, temperate japonica, and tropical japonica). GWA analysis was completed using the high-density rice array (HDRA) and the rice reference panel (RICE-RP) SNP sets.ResultsWe identified 18 genomic regions related to root hair traits, 14 of which related to RHD and four to RHL. No genomic regions were significantly associated with both traits. Two regions overlapped with previously identified quantitative trait loci (QTL) associated with root hair density in rice. We identified candidate genes in these regions and present those with previously published expression data relevant to root hair development. We re-phenotyped a subset of lines with extreme RHD phenotypes and found that the variation in RHD was due to differences in cell differentiation, not cell size, indicating genes in an associated genomic region may influence root hair cell fate. The candidate genes that we identified showed little overlap with previously characterized genes in rice and Arabidopsis.ConclusionsRoot hair length and density are quantitative traits with complex and independent genetic control in rice. The genomic regions described here could be used as the basis for QTL development and further analysis of the genetic control of root hair length and density. We present a list of candidate genes involved in root hair formation and growth in rice, many of which have not been previously identified as having a relation to root hair growth. Since little is known about root hair growth in grasses, these provide a guide for further research and crop improvement.

Sources, Migration, Transformation, and Environmental Effects of Organic Carbon in Eutrophic Lakes: A Critical Review.

Organic carbon (OC) plays a leading role in the carbon cycle of lakes and is crucial to carbon balances at regional and even global scales. In eutrophic lakes, in addition to external river inputs, the decomposition of endogenous grass and algae is a major source of organic carbon. Outbreaks of algal blooms (algal eutrophication) and the rapid growth of aquatic grasses (grass eutrophication) can lead to the accumulation and decay of large amounts of algae and aquatic grass debris, which increases the intensity of the carbon cycle of lakes and greatly impacts aquatic environments and ecosystems. The structures, decomposition processes, and distribution characteristics of algae and higher aquatic plant debris in eutrophic lakes are different from mesotrophic and oligotrophic lakes. Studying their accumulation dynamics and driving mechanisms is key to further understanding lake carbon cycles and their many interdependent pathways. This paper focuses on the carbon sources, tracing technologies, migration and transformation processes, and environmental effects of OC in eutrophic lakes. Based on the existing knowledge, we further combed the literature to identify the most important knowledge gaps preventing an in-depth understanding of the processes and driving mechanisms of the organic carbon cycle in eutrophic lakes.

GRASSROOTS ЯК НЕПРЯМИЙ МЕТОД ЛОБІЮВАННЯ ПОЛІТИЧНИХ РІШЕНЬ

Interest groups use a sophisticated combination of various methods and technologies in their lobbying activity, their list expands and diversifies in a digital society and differs depending on the subject of lobbying and available resources for influence. To increase the effectiveness of lobby campaigns along with traditional methods of direct influence, interest groups seek to create a certain impression about a particular issue in the public. For these purposes indirect methods of lobbying are widely used, they do not have a specific target audience, they are applied outside the offices and corridors where government officials make their decisions. Among these indirect methods of lobbying, grassroots take a special place. This term grassroots refers to the self-organized activity of groups, their attempt to influence "from the bottom up" by analogy with the growth of grass from the roots. Grassroots involves influencing decision-makers not directly, but through the public, mobilizing support for political interest through mass communication. The power of grassroots is not in financial resources, but in the ability to use the beliefs and efforts of ordinary citizens to shape the political agenda. To mobilize community lobbyists use a combination of public affairs and media relations tools. This method of influence is widely used by non-governmental organizations around the world to ensure the protection of human rights in various spheres at the local, regional, national and international levels - from race, national, religion, gender discrimination to the abortion and climate change. The article analyzes grassroots as a method of lobbying influence by mobilizing the public around a political issue; its content and essence, advantages and risks to the political system are defined. It is determined that grassroots not only enhances the effectiveness of interest group lobbying, but also makes a significant contribution to the development of democracy by promoting public awareness of important political issues, helping ordinary citizens understand the essence and consequences of legislation from a layman's perspective. The author identifies the main grassroots tools, demonstres the specifics of their effective application, emphasizes the key role of mass communication, including social networks, in organizing grassroots lobbying to expand audience coverage and mobilize public support. The importance of astroturfing lobbying as an imitation of grassroots, the creation of artificial public support for political decisions and events, which threatens the democracy and transparency of the political process, is established. Key words: astroturfing, grassroots, interest groups, lobbying, grassroots initiatives, political communications, political decision.

Geographic information system technologies in the study of deformation in rivers

The article examines the possibilities of assessing the changes and condition of the riverbed using remote sensing (RS) and geoinformation systems (GIS) technologies. Deformation processes observed in the last 25 years in the Sox stream bed selected as a research object were evaluated on the basis of modern geoinformation systems. The processes taking place in River were studied on the basis of satellite data. Landsat satellite generations were selected for analysis. To download the data, the official site of GloVis, which is widely used today, was used. The data was analyzed using the ArcMap software. The results of GIS analysis were compared with field experiments. In the last 20 years, the direction of the flow along the right bank has changed, the left bank sections are covered with silt particles, grass growth and washing processes are observed on the left bank. Over the past 5 years, 30 m of cultivated land has been washed away along the right bank between PK 3 and PK 4. These changes average 4-5 m per year. The deformation processes observed in the river are analyzed and conclusions are drawn.

Spatial variability of soil properties and its effect on meadow productivity

The spatial heterogeneity of the yield of perennial grasses was studied to identify soil factors that most affect the productivity of sown meadows in South Karelia. Soil variability was studied using various statistical and geostatistical methods. In the course of research, it was found that the best conditions for the growth of perennial grasses are created on soils with a carbon content of about 8% and a slightly acidic or close to neutral reaction environment. It is noted that the type of soil affects the organic carbon content and change in the yield of perennial grasses. In the diagnostic range of peat soils, as the transition from peat-mineral soils to peat soils the organic carbon content in the soil increases and the yield of grasses decreases. The acidity distribution is rather anthropogenic in nature.

The yellow river-bed evolution a statistical proof of the mountain-river-desert conjecture

When the Yellow River flows through the Hetao Plain in Inner Mongolia, north China, it forms a mountain-river-desert system with the Yin Mountains on one side and the Hobq desert on the other side. In this mountain-river-desert system, a dense growth of green grass is formed in the area fronting the river and with the mountains at the back, however, on the opposite the river, the area has an inherent trend to lost moisture, which might cause desertification. This study verifies this theoretical conjecture by analyzing the Yellow Riverbed change from 2014 to 2021. The seven year change showed the river is the inherent boundary between the grassland and the dessert, and it was nothing to do with the river banks? past earth surfaces.

ICP-MS Analysis of Elemental Composition in Soil and Forage Plant Irrigated with Sewage water and Bore Well Water

Ensuring sufficient nutrition for livestock is crucial for maximizing livestock productivity besides bridging the widening gaps between demand and supply of green fodder. The cumbu napier hybrid grass, known for its high biomass yield per unit area and wider adaptability has played a vital role in managing the green fodder requirement to a substantial extent is the focus of the current study. Present research aims to explore the impact of sewage wastewater on the growth of Cumbu Napier hybrid grass. The findings revealed that elevated levels of heavy metals viz., 37.77 ppm (parts per million) of lead and 10.46 ppm of tin accumulation in Cumbu Napier hybrid grass grown in soil irrigated with sewage water was recorded as compared to those irrigated with borewell water where 7.73 ppm of lead and 1.92 ppm of tin were registered. Hence, the results indicated that recycling the sewage water for high water demanding forage crops such as cumbu napier hybrid grass found to accumulate more heavy metals than bore well water. The order of mean concentrations of heavy metals in the soil obtained was Sn&gt;Sb&gt;As&gt;Pb&gt;Cd.

A Preliminary Assessment of Utilizing Solid Waste Fractions as an Agricultural Growth Medium in Arid Soils

The fast-paced and globalized industrial/population growth has generated a vast consumerism-based culture, resulting in the rapid increase in municipal solid waste generation. Considering the case of Kuwait, the collection and disposal of waste has become a major economic and health issue for both the general public and the Kuwaiti government. Addressing and improving current waste disposal challenges, through utilizing (or recovering) basic materials from waste, will benefit society in terms of reductions in costs, pollution and associated negative health impact. The objective of this study was to assess the re-utilization prospects of waste materials (paper, cardboard and cotton) as a substrate for plant growth, consequently serving as a growing medium material, apart from naturally occurring soil. This investigation was conducted across two land plots in the Wafra region, located in Southern Kuwait. The plots were planted with Rhanterium epapposum and Festuca rubra seeds. Temperature, humidity and growth rates were measured during this study. Study results indicated that chemical composition of the growth medium is suitable for local conditions. Furthermore, the soil plot with added growth medium was found to retain moisture for prolonged periods in comparison to the plot lacking in growth medium. Field studies on grass germination and growth rates highlighted that waste-derived substrate is favorable to their development and adaptation within challenging environmental conditions. This investigation can play an important part for introducing and developing the concept of a circular economy within Kuwait, with potential to improve waste management within the country.

Isolation and characterization of endophytic bacteria from Pennisetum purpureum Schumach

Pennisetum purpureum Schumach, commonly called elephant grass, found in tropical and subtropical climates is used as an energy crop as well as a forage grass. As part of an ongoing exploration of environmentally friendly agricultural approaches in Vietnam, which includes the utilization of endophytic species and endogenous bacteria in fertilizer synthesis, studies were conducted on elephant grass. Elephant grass specimens were gathered and examined to investigate the advantages of endogenous bacteria during elephant grass growth. Endogenous bacteria capable of generating IAA were identified from Pennisetum purpureum Schumach samples collected in the provinces of Hai Duong, Cao Bang, and Thai Nguyen. Five of these strains were chosen for their capacity to stimulate plant development and fight harmful bacteria. All selected strains were gram-negative and motile endophytic bacteria. After 72 hours in a medium with a pH of 7, 100 mg/l L-tryptophan, and 30°C on liquid NA media, the study identified five endogenous bacterial strains (HDR5, HDR9, TNT3, CBR1, and CBR2) that produced the maximum amounts of IAA. HDR5 and CBR2 strains demonstrated the ability to inhibit plant-pathogenic Xanthomonas strains. The investigation of HDR5’s 16S rRNA nucleotide sequence revealed that it is closely linked to the genus Enterobacter. The study suggests the use of endogenous bacteria in fertilizer synthesis as an effective and eco-friendly approach.

Utilising commercial farm grass growth data to evaluate long-term dry matter production of perennial ryegrass varieties

Little data are currently available on either the dry matter (DM) production of perennial ryegrass (PRG) swards as they age beyond 5 yr (i.e. permanent pasture) or the performance of PRG varieties on commercial grassland farms. Previous work has generally assumed a connection between DM production and ground score (GS) and this link has been used as a proxy for variety persistence. The evolution of technology in the form of PastureBase Ireland has led to agronomic data of individual paddocks being made available for analysis over multiple years which has allowed the long-term assessment of varieties sown as monocultures on commercial farms. This technology allowed for the inclusion of eight PRG varieties sown in 649 paddocks across 101 farms in Ireland in the current analysis. The results show little association between GS and variety DM production as varieties age to 7 yr. Dry matter production of 1- to 4-yr-old swards appeared to provide a strong indication of variety DM production in years 5–7 post-sowing (r = 0.72, P &lt; 0.05). The interaction of variety and sward age was not associated with DM production. Generally, varieties which produced the most DM in younger swards also produced the most DM in permanent pasture swards. Over longer-term periods these variety differences can manifest into large differences in DM produced and consumed on farm. The current analysis suggests that the long-term production benefits of utilising improved PRG varieties in pasture reseeding may be underestimated.

Effects of Liquid Organic and NPK Fertilizers on the Nutrient composition of Grass Jelly (Premna oblongifolia Merr) in Tropical Peat Soil

Peat soil is deficient in nutrients and agricultural development in this type of low in fertility soil is very difficult. Grass jelly (Premna oblongifolia) is a dark green shrub-like medicinal plant that has been widely used for its nutritional and medicinal properties. This study aimed to evaluate the effect of foliar application of organic fertilizers and NPK on the growth, nutrient absorption, and flavonoid content of grass jelly plants grown in peat soil. The study was carried out in a completely randomized factorial design with two factors including liquid organic fertilizer and NPK inorganic fertilizers. Three doses of liquid organic fertilizer consisting of P0 (without liquid organic fertilizer), P1 (Agrobost), and P2 (Nasa), and three levels of NPK fertilizer consisting of N0 (0g NPK polybag-1), N1 (1 g NPK polybag-1), and N2 (2 g NPK polybag-1). The results of the study revealed a nonsignificant interaction between liquid organic fertilizer and NPK fertilizer in terms of leaf growth, leaf area, fresh weight, and flavonoid of grass jelly plant growth. Further, in the case of plant nutrient contents, combined application of Nasa liquid organic fertilizer and 2 g polybag-1 NPK fertilizer tends to increase the nutrient content of N, P, and K and have the highest impact as compared to other treatments. The results of the study can be concluded that administration of liquid organic fertilizer and NPK did not affect the plant growth characteristics of grass jelly plants while in the case of nutrient content except flavonoids the level of N, P, and K of plant leaves increased.
