Abstract

Litter is a fragment of aboveground carbon stocks, a vital bridge to the belowground carbon cycle. Land conversion to agricultural purposes will affect litter production. This study aimed to compare the litter production of natural forests with cocoa-based agroforestry systems (AFS) in West Sumatra. Litter production was measured in five different types of ecosystems, namely natural forest (NF), cocoa-rubber-based AFS (CR), multistrata cocoa-based AFS (CM), cocoa-coconut-based AFS (CC), and cocoa monoculture (M). This study is quantitative research with the collection method. The difference in litter production between the five ecosystems observed was tested using ANOVA parametric statistical method. Litter was collected monthly for one year in which litter traps were evenly distributed in each research plot. Ecosystems of NF and M produced the highest annual litter (6.04 Mg ha-1 and 4.65 Mg ha-1 respectively), while CR produced the lowest one (2.52 Mg ha-1). Although this study did not perform comprehensive modeling of decomposition dynamics, the measurement of annual litter production can provide a further understanding of the dynamics of ecosystem carbon, especially in cocoa-based agroforestry.

Abstract

Rorippa indica L. Hiern is a local vegetable that is widely consumed by Dayak’s tribe in Central Kalimantan, Indonesia. It is mostly traditionally cultivated without fertilizers, resulting in low productivity. The research aimed to investigate the effect of fertilizers and soil type on the growth characteristics and N uptake of R. indica. The experiment was arranged in a factorial completely randomized design consisting of two factors with four replications. The first factor was fertilizer application (control, 20 t ha-1 of chicken manure, and 600 kg ha-1 of NPK), and the second was soil type (peat and Ultisol). The results revealed that the interaction of fertilizers and soil type gave a non-significant effect on all variables observed, except N uptake. The application of NPK increased the plant height and number of leaves significantly. Compared to control, the increment was 112.50% and 130.32%, respectively, and chicken manure application increased the dry weight (327.87%), N total (310.16%), and N uptake of plants by 478% in peat soil and 228% in Ultisol. This finding concludes that 20 t ha-1 of chicken manure can be applied to increase the productivity of R. indica.

Abstract

Ginger (Zingiber officinale) is the main biopharmaceutical export commodity of Indonesia. However, its productivity and quality are low because it is not cultivated using optimal techniques. This study aimed to examine the effect of magnesium (Mg) fertilizer on the growth, rhizome yield, and essential oil content of two ginger varieties in the organic field. The two factors tested were the rate of Mg fertilizer application (0, 50, 100, and 150 kg MgOha-1) and the variety of ginger (elephant ginger [Zingiber officinale var. officinarum] and red ginger [Zingiber officinale var. rubrum]). The variables measured were plant height, number of leaves, number of tillers, rhizome weight, and essential oil content. Mg fertilizer application rate and ginger variety significantly affected growth, yield, and essential oil content. No interaction effects were found between the two factors. Mg fertilizer applied at 150 kg MgOha-1 resulted in the highest rhizome yield and essential oil content, with an increase of 21.74% and 15.38%, respectively, compared to the control (0 kg MgOha-1). The yield of elephant ginger was 29.41% higher than that of red ginger, whereas the essential oil content of the red ginger was 16.67% higher than that of the elephant ginger.

Abstract

Tobacco stems contain 56.10% cellulose content, 15.11% lignin, 22.44% hemicellulose, and 44.61% total organic carbon, which can be used as a source of energy or fuel. This study aimed to utilize tobacco stems in a briquette form as alternative energy. The materials used in this study were tobacco stem waste, rice husk, wood charcoal, and coconut shell. The treatments used in this study consisted of T1 (100% of tobacco stems), T2 (80% of tobacco stem + 20% of coconut shell), T3 (80% of tobacco stem + 20% rice husk), and T4 (33.33% of tobacco stems + 33.33% of rice husk + 33.33% coconut shell). The fastest combustion rate was found at T3, 0.12 gram/sec, while T1 and T2 had the same combustion rate. T4, a mixture of various materials, had no significant difference compared to T1, T2, and T3. The highest calorific value of tobacco stem briquettes was in T4 (4127 Kcal/kg), and the lowest was in T1 (2343 Kcal/kg). The combustion rate of these tobacco stem briquettes was longer than that of charcoal briquettes, whose average burning rate is 0.234 grams/second. Overall, this study provides an overview of the best combination to create briquettes from agricultural waste.

Abstract

Agriculture land shows soil compaction problems due to long-term agricultural cultivation activities. Soil compaction indicator can be seen from the value of soil penetration resistance at different soil depths (0 - 60 cm). This research aimed to determine soil penetration resistance at different coffee plantation ages with different soil depths and to analyze the relationship between soil penetration resistance with soil physical characteristics and coffee productivity. The survey activities include observation of minipits, measuring soil penetration resistance at soil depths of 0-20 cm, 20-40 cm, and 40-60 cm using a hand penetrometer, and soil sampling. The results showed that the soil penetration resistance at each LU and soil depth suggested variation were categorized into moderate and high soil penetration resistance classes (1.34 MPa - 3.35 MPa). Soil characteristics, such as soil aggregate stability, water content, bulk density, porosity, silt content, and clay content, significantly correlate with soil penetration resistance. However, soil penetration resistance has a negative correlation with coffee productivity. The value of soil penetration resistance (at a depth of 0-60 cm) has a significant negative correlation with the average productivity of coffee plantations (r=-0.5936**). Therefore, increased soil penetration resistance decreased root growth, decreasing plant productivity.

Abstract

Oil palm empty fruit bunches are materials used as organic fertilizers that can be applied to oil palm plantations, thereby reducing the use of inorganic fertilizers. Indigofera zollingeriana is an appropriate alternative as an interplant because of its high branch and leaf development. Functions as a ground cover and a supplier of carbon stocks naturally plays a role in water and soil conservation. This study aims to determine the effect of oil palm empty fruit bunches and I. zollingeriana on land improvement to support oil palm growth and production. Variables observed included changes in soil water content, soil microorganism activity, and carbon stock. The results showed that the soil planted with I. zollingeriana and given the empty fruit bunches of oil palm had a higher soil moisture content. The highest soil carbon stock, oil palm carbon stock, and vegetation carbon stock were 81.6 t ha-1, 36.60 t ha-1, and 1.89 t ha-1, respectively. The population and activity of microorganisms varies. The highest total microorganisms were treated with I. zollingeriana and oil palm EFB 105 (10⁵CFU g-1), while the lowest was 60 (10⁵CFU g-1). Planting I. zollingeriana and providing oil palm empty fruit bunches increased groundwater reserves by 36.71%.

Abstract

The productivity of potatoes (Solanum tuberosum L.) in Indonesia is still low. Fertilization needs to be done to increase potato productivity. This study aimed to examine the effects of applying oil palm empty fruit bunch (OPEFB) ash nanoparticles on the anatomy of potato stomatal and leaf cells (Solanum tuberosum L.). The research was carried out from March to June 2021 in the Sumberejo Village, Ngablak District, Magelang Regency, Central Java, and at the Agrobiotechnology Laboratory, Faculty of Agriculture, University of Muhammadiyah Yogyakarta. The study used a single-factor treatment design with a Randomized Completely Block Design (RCBD). The treatments tested included the foliar application of OPEFB ash nanoparticles at several concentration, consisting of 0% (control), 0.1%, 0.2%, 0.3%, and 0.4%. The results showed that foliar application of nanoparticles OPEFB ash affected stomatal anatomy, namely guard cell width, stomatal aperture, and density. The application of OPEFB ash nanoparticles with a concentration of 0.3% was most effective in increasing the opening of stomata because it affects the activity of the photosynthetic process.

Abstract

The growth and yield of plants are strongly influenced by the early growth ability of the plants. Similar germination and good seed vigor will greatly support plant growth and increase production. Increasing the germination and vigor of seeds can be done through biopriming. The application of biopriming using rhizobacteria is developing environmentally friendly agricultural technology. This study aimed to determine the effect of inoculation of rhizobacteria from the north coast of Pemalang on rice plants' germination and vigor index. The study was arranged in a Randomized Block Design, consisting of 10 treatments with three replications. Ten rhizobacteria isolates were isolated from the North Coast of Pemalang, Central Java, consisting of Ju1, Jn3, Jn1, J, J12, J5, Kn1, A3, Jn, and K3. The biopriming with rhizobacteria isolated from the rice rhizosphere of the Northern Coast of Pemalang increased the seed germination rate, seed vigor index, and early vegetative growth of rice seedlings. Inoculation with isolate J12 produced the highest vigor index of 8280.01. The results of this study imply that the application of rhizobacteria from saline soil has the potential to increase the vigor of rice seedlings to impact better seedling growth in saline conditions.

Abstract

Gunungkidul is a production center of cassava (Manihot esculenta Crantz), a carbohydrate source and raw material for food industry. AMF inoculation in cassava plants is known to increase biomass production. However, little studies have been conducted on the response of cassava to mycorrhizal inoculation and organic fertilizer. Therefore, this study was aimed at examining the effects of AMF inoculation and types of manure on the AMF colonization and yield of cassava in Gunungkidul. The research was carried out by planting cassava in Alfisol Gunungkidul arranged in a randomized complete block design with two factors, AMF doses of 25g; 50; and 75g/plant; and types of manure i.e. cow, goat, and poultry manure, for five months period. Rhizosphere soil and root samples were analyzed for AMF colonization and the spores number. The results showed that AMF-infected cassava roots combined with cow or goat manure application produced more spores than poultry manure. AMF infection and manure, thus, significantly resulted in better root proliferation, root forehead weight, tuber diameter, and cassava products, than the absence of both treatments. Cow manure combined with AMF at a dose of 25 g/plant significantly affected the dry weight of cassava roots. This study implies that applying AMF and manure provide a substantial contribution on the growth and production of cassava.

Abstract

Nanotechnology can be used to produce slow-release fertilizers. Zeolite and crab shells are materials that can be used as fertilizer encapsulation. This study aimed to compare the effects of nano zeolite and crab shells for encapsulation of nitrogen- potassium fertilizers tested on Entisols and Inceptisols soil on the growth and yield of shallots. The research method used a completely randomized design with three factors. The factors were soil type (Entisol and Inceptisol), coating materials (nano-zeolite and nano-crab shell), and NK fertilizer doses (125:50, 250:100, 375:150, and 500:200). The variables observed include initial soil physical and chemical properties, nanoparticle characterization, growth and yield, and agronomic efficiency. Nanoparticles were characterized using SEM and analyzed using ImageJ. The data collected were tested by ANOVA and Tukey. The ball milling method succeeded in producing 91.41% zeolite and 97.50% nano-sized crab shells. Plant height showed that using crab shells as fertilizer encapsulation with a dose of 125:50 gave better results. The yield of crab shells as encapsulation with a dose of 250:100 in inceptisols was better than that in entisols, but the highest agronomic efficiency (EA) was obtained in zeolite treatment as fertilizer encapsulation with a dose of 125:50.
