Abstract

White turmeric is a medicinal plant widely used to treat various diseases. The limited availability of white turmeric seedlings is influenced by the scarcity of quality seeds due to the long dormancy of the rhizomes and the high incidence of pathogen attacks. Tissue culture techniques are one alternative to address the problem of white turmeric seedling availability. This study aims to determine the best concentrations of meta-topolin and kinetin for in vitro shoot multiplication of white turmeric. The research was conducted from January to June 2022 at the tissue culture laboratory, Faculty of Agriculture, Universitas Padjadjaran. This study used a completely randomized design consisting of 7 treatments: control (0 mg L-1), meta-topolin (1 mg L-1; 2 mg L-1; 3 mg L-1), kinetin (1 mg L-1; 2 mg L-1; 3 mg L-1). Analysis of variance (ANOVA) and Duncan’s multiple range test were used to analyze the statistical effects of meta-topolin and kinetin application. Applying 1 mg L-1 meta-topolin yielded the best results for shoot number, indicating that 1 mg L-1 meta-topolin is a potential cytokinin for the propagation of Curcuma zedoaria Rosc.

Abstract

Giant false sensitive plants (Mimosa invisa Colla) and giant sensitive plants (Mimosa pigra L.) are invasive plant species in the tropics and native to America. They are widely distributed in different ecosystems and soil types. Apart from being considered woody shrub weeds, these plant species can be used as herbal medicine for their antioxidant activities. An experiment to study the antioxidant activities and phytochemicals of M. invisa and M. pigra grown at 200 m from the coastline and close to the riverbank (riparian abandoned land) was carried out from March to November 2023. Weed leaves were collected as purposive randomized sampling from different terrestrial habitats in the City of Padang, West Sumatra. Antioxidant activity was identified according to a 2-2-diphenyl-1-picrilhydrazil (DPPH) radical-scavenging assay, and phytochemical compounds were identified qualitatively. Results demonstrate that M. invisa had mild antioxidant activity and M. pigra had strong antioxidant activity. The IC50 values for M. invisa grown at 200 m from the coastline and at the riverbank were 121.3 ± 11.5 and 105.6 ± 2.90 ppm, respectively. The IC50 values of M. pigra grown at 200 m from the coastline and at the riverbank were 80.6 ± 15.9 and 85.1 ± 9.03 ppm, respectively. Phenolic, saponin, and steroid were detected in all weeds grown at different habitats. However, alkaloids and terpenoids were not detected. Interestingly, flavonoid was not detected in the leaves of M. pigra grown at the riverbank.

Abstract

Weeds are managed by herbicides, but this can reduce the abundance of soil bacteria. This research aimed to determine the effect of active compounds of herbicides on weeds, the abundance of soil bacteria, growth and yield of sweet corn. The experiment was conducted from June to October 2023 in the fields and Laboratory of Agronomy and Horticulture, Universitas Jenderal Soedirman, Purwokerto. A randomized block design was used, consisting of eight treatments and four replications. The treatments included control (H0); weeding (H1); paraquat (H2); glyphosate (H3); paraquat, atrazine, mesotrione (H4); glyphosate, atrazine, mesotrione (H5); paraquat, atrazine, mesotrione, nicosulfuron (H6); and glyphosate, atrazine, mesotrione, nicosulfuron (H7). Results showed that glyphosate and paraquat, were applied before planting, could suppress weeds on sweet corn until 15 days after planting (DAP). Application of atrazine, mesotrione, and nicosulfuron at 21 DAP can increase the success of weed control observed up to 35 DAP of sweet corn. The application of glyphosate, atrazine, and mesotrione showed the highest values for growth variables (plant height, number, and leaf greenness index) and yield variables (fresh weight, diameter, and length of sweet corn cob). Herbicide decrease abundance of soil bacteria on sweet corn field, from 10.07x10-8 CFU/mL to 9.55x10-8 CFU/mL (total bacteria), 9.53x10-8 CFU/mL to 9.52x10-8 CFU/mL (phosphate solubilizing bacteria), 9.90x10-8 CFU/mL to 9.40x10-8 CFU/mL (Rhizobium) and 9.91x10-8 CFU/mL became 9.78x10-8 CFU/mL (nitrogen fixing bacteria). The total density of phosphate-solubilizing bacteria and nitrogen-fixing bacteria in the application of glyphosate, atrazine, and mesotrione (7.78 CFU/g and 9.52 CFU/g) was greater than control (8.77 CFU/g and 8.15 CFU/g).

Abstract

Climate change occurred in Karawang Regency due to extreme weather events, which are included in the El Nino climate anomaly phenomenon. The existence of extreme weather events in Karawang Regency has decreased rice production, which is a climate-dependent crop. Based on this problem, a study was conducted to analyze the identification of extreme weather changes and correlation analysis of rice crops in Karawang Regency to see the magnitude of extreme weather changes and the influence of extreme weather elements on rice crops. The method used is a quantitative descriptive method by analyzing extreme weather changes, correlation analysis of extreme weather elements on rice plants (production, productivity, and harvest area), and correlation graphs of extreme weather elements with rice plants. Data was obtained from BPS, BMKG, and the Karawang Regency Agriculture and Food Security Office. The results showed that Karawang Regency experienced extreme weather changes due to climate change, namely an increase in the average maximum rainfall (1.78 mm), an increase in maximum temperature (0.76 °C), a decrease in minimum temperature (-0.57 °C), a decrease in wet spell for 3 days, and an increase in dry spell for 10 days. The impact of extreme weather change, namely the wet spell element, has a real significant correlation with a moderate level to a decrease in rice production and productivity.

Abstract

Roses are known as a high-value commodity frequently used in various important events. However, they are susceptible to postharvest quality deterioration, which can affect their vase life and appearance. In this study, roses with a blooming stage of approximately 25–50% were immersed in melatonin and 6-benzylaminopurine (BAP) solutions at different concentrations. This research aims to analyze the effect of melatonin and BAP application on the freshness of cut roses. The parameters observed included flower vase life, flower wilting angle, increase in flower diameter, fresh weight, solution uptake, and chlorophyll content. The results showed that melatonin and BAP, applied individually or in combination, effectively extended the freshness of cut roses by up to eight days by maintaining solution uptake, flower quality, and chlorophyll content. This study provides new insights for farmers and researchers in improving the quality and longevity of cut roses through the use of plant hormones, particularly cytokinin.

Abstract

Sustainable rice farming is increasingly threatened by declining soil fertility, excessive reliance on chemical fertilizers, and environmental degradation from intensive agricultural practices. There is an urgent need for innovative organic fertilizer products that combine organic materials with macro and micronutrient enhancements to restore soil health effectively. This research aimed to evaluate the effect of organic plus fertilizer (OPF) as a sustainable soil amendment to improve soil nutrient status, increase paddy productivity, and enhance overall soil health. The experiment was conducted using a Randomized Block Design (RBD) with nine treatments: one recommended OPF dose, six combinations of NPK (75 – 100%) and OPF (75 – 150%), one recommended conventional NPK dose, and one control. Variables observed included plant growth, yield, and yield components, total soil nitrogen, and plant uptake of N, P, and K. Results indicated that OPF combined with NPK significantly increased plant height (29.13 – 31.38%) and number of panicles (57.89%) compared to the control. Nutrient uptake improved for nitrogen (23.68%) and potassium (15.96 – 21.28%), although no significant improvement was observed for phosphorus. Yield parameters showed an 81.97%–118.50% increase over the control. The combinations of 75% NPK + 150% OPF, 100% NPK + 75% OPF, and 100% NPK + 100% OPF produced taller plants, higher yields, greater nutrient uptake, and lower residual nitrogen in the soil. For optimal rice yield and soil health, integrated application of OPF with either a full or 75% NPK dose is recommended.

Abstract

 Drought stress is a major limiting factor affecting the growth, yield, and quality of tea (Camellia sinensis). The present study aimed to analyze the success of post-drought growth recovery of tea in response to different techniques and doses of biofertilizer applications. Field experiments were conducted from January to August 2024 in the experimental garden of the Research Institute for Tea and Cinchona, Gambung Blok A8, Bandung. This work was arranged in a split-plot design, consisting of a main plot with two biofertilizer application techniques (foliar feeding and soil drenching) and subplots with four levels of biofertilizer dosage (control (B1), 15 L ha-¹ (B2), 22.5 L ha-¹ (B3), and 30 L ha-¹ (B4), with three replications. The results showed a significant interaction of biofertilizer dose and technique on shoot dry weight and plant growth rate of tea. There was an independent effect of biofertilizer dose on leaf area ratio. Applying a biofertilizer dose of 15 L ha-1 through soil drenching produced the best plant growth rate and shoot dry weight at the 6th harvest.

Abstract

Information on soil resources in volcanic landscapes presents a high potential for agricultural land development, but its development is always faced with the potential for continuous land degradation. This study aims to reduce the rate of land degradation through the application of vegetative conservation in erosion-prone Loto agrotourism area, Ternate Island. The research location is focused on erosion-prone areas. The research consisted of a soil resource inventory and a vegetative conservation application. The vegetative conservation application method used a Randomized Block Design (RBD) pattern, composed of 2 factors. The first factor is mulching, namely: no mulching (M0) and mulching (M1), while the second factor is chicken manure-based organic fertilizer, specifically at 10 tons ha-1(P1), and 20 tons ha-1(P2). Observation parameters include soil parameters as well as plant growth and yield parameters. The results showed that the combination of mulching and chicken manure had an insignificant effect on plant height, number of flowers, number of fruits, or number of branches. However, the application of mulching was found to increase the fruit weight of curly chili plants. This finding implied that erosion-prone areas require improved land management, such as mulching, to optimize soil resources and reduce erosion risk.

Abstract

Wood ear mushrooms are often consumed in Asia and Tropical America for their jelly-like texture, health, and freshness. However, they are easily damaged due to microbes and poor postharvest handling, which affects quality. The combination of nano edible coating, packaging, and storage temperature offers a solution to these issues. This study aims to evaluate the effect of nano edible coating, packaging, and storage temperature on the color (L*, a*, and b*), water content, and antioxidant properties (total phenolic and flavonoid) of wood ear mushrooms. The study was conducted at the Horticulture Laboratory, Faculty of Agriculture, Universitas Padjadjaran. The experimental design used was a Completely Randomized Design with a total of 18 combinations of nano edible coating (sodium alginate and aloe vera), packaging (biodegradable, wrap, and vacuum plastic), and storage temperature (±25 ℃, 10 ℃, and 5 ℃). Each treatment was replicated twice, resulting in 36 experimental units, with 3 mushrooms per unit for a total of 108 mushrooms. The results showed a significant effect of the combination treatments on L* at 9 days after treatment (DAT), a* at 6 DAT, water content at 6 and 9 DAT, total phenolics, and total flavonoids during the storage period. Nano aloe vera with vacuum packaging at 5 ℃ gave the best effect on L* value at 9 DAT, water content at 6 and 9 DAT, total phenolic at 3 and 6 DAT, and total flavonoid at 6 DAT. These results indicated the potential of the treatment in maintaining the quality of the wood ear mushroom during storage.

Abstract

Rabbit urine liquid organic fertilizer (LOF) can be used as an alternative fertilizer to reduce the use of inorganic fertilizers, especially for shallots, as a national food commodity. This study aims to determine the best concentration of rabbit urine LOF, the best dose of NPK fertilizer dose reduction, and a combination of rabbit urine LOF and NPK fertilizer dose reduction on the physiological characters of shallot plants. The observed variables consisted of net assimilation rate, crop growth rate, stomatal density, stomatal aperture, and chlorophyll content. The experimental results showed that a concentration of 200 mL L-1 of rabbit urine LOF had the best effect on several physiological characteristics studied. In addition, a 50% reduction in the NPK dose had the best effect on physiological characteristics compared to other treatments. Rabbit urine LOF 200 mL L-1 and a 50% reduction in NPK doses had a significant interaction effect on the physiological characters of shallot plants.
