Abstract

Rice (Oryza sativa L.) is a vital food crop that serves as the staple food for over half of the world's population due to its rich nutritional value. This study aims to determine the physiological and morphological characteristics of several rice varieties cultivated using the System of Rice Intensification (SRI) with varying seed densities. The research will be conducted in Geulumpang Payong Village, Jeumpa District, Bireuen Regency, situated at an altitude of approximately 0-969 meters above sea level (masl), from August to December 2024. The study will employ a Randomized Block Design (RBD) methodology. Two factors will be tested: rice varieties (Ciherang, Inpari 49, and Mustajab) and the number of seedlings per planting hole (4, 3, 2, and 1 seedling). A total of 12 treatments were conducted, with each treatment replicated three times, resulting in 36 experimental units. Each experimental plot measured 2 m x 2 m, with a planting distance of 25 cm x 25 cm, accommodating 81 plants per plot. Four sample plants were selected from each plot for analysis. The data obtained from the research were statistically analyzed using the F-test with SAS V9.12 software. If the analysis of variance indicated significant differences at the 5% level, a subsequent Duncan's Multiple Range Test (DMRT) was performed. The results suggested that the variety, number of seedlings, and their interaction did not show significant differences across all parameters. However, the Inpari 49 and Mustajab varieties, along with the treatment of four seedlings per planting hole, demonstrated relatively favorable outcomes.

Abstract

Moringa is often referred to as the "miracle tree" due to its rich nutrient content and medicinal properties. The increasing demand for moringa seeds has highlighted the need for effective propagation methods; however, germination remains limited by the hard seed coats and prolonged dormancy periods. This gap underscores the importance of studying moringa, particularly in efforts to enhance germination success and initial growth. This study aims to evaluate the effects of various seed priming materials, soaking durations, and the interactions between different types of seed priming materials and soaking times on the vigor and viability of moringa seeds. The research was conducted in the Biotechnology Laboratory and greenhouse at the Faculty of Agriculture, National Development University "Veteran" East Java. This study employed a Completely Randomized Design (CRD) with a factorial arrangement of two factors, comprising fifteen combinations and three replications. The first factor is the type of seed priming material (S), which includes Aqua Destillata, seaweed extract, coconut water, PEG 6000, and KNO3. The second factor is the soaking time for the priming solution (L), which consists of 12 hours, 24 hours, and 36 hours. Observations include germinability, maximum growth potential, growth rate, vigor index, and sprout weight. The combination treatment of PEG 6000 as the seed priming material with a soaking time of 12 hours yielded the highest average values for germination and maximum growth potential. A single treatment using PEG 6000 resulted in the highest average vigor index. Additionally, a single treatment with a soaking duration of 12 hours also produced the highest average vigor index. The results of this study can be recommended as optimal treatments to enhance the germination capacity and vigor of Moringa seeds.

Abstract

Rice (Oryza sativa L.) is a staple food crop that is being promoted as part of efforts to enhance national food security. The utilization of dry land in Indonesia is one mechanism that supports this food security initiative. Seed priming treatments have been shown to improve plant tolerance to drought stress conditions. This adaptation study aims to investigate the differences in seed viability among several rice varieties subjected to different concentrations of ZnO nanopriming, as well as the performance of selected seeds grown under drought stress conditions during the vegetative phase of the plants. The first phase of the research involved seed screening and variety selection, accompanied by seed priming treatments. The experimental design employed was a Factorial Randomized Block Design, with the first factor being ZnO concentrations of 0 ppm, 10 ppm, 15 ppm, and 20 ppm. The second factor involved the selection of four rice varieties: Ciherang, Inpari 32 HDB, Mekongga, and the expired Ciherang. The second phase of the research built upon the first phase, utilizing the best rice seeds identified from the screening results along with the most effective priming treatment. These seeds were subjected to drought stress treatments (without watering), which included 0 HTS, 5 HTS, 7 HTS, and 14 HTS. The results indicated that the seed priming treatment with ZnO nanoparticles (NPs) significantly increased the germination percentage of rice seeds across all varieties, with the optimal treatment combinations being 30 ppm for the Ciherang variety and 100 ppm for the Mekongga variety. Under drought stress conditions, the Ciherang variety at 30 ppm exhibited the best adaptation up to 14 HTS. Overall, the application of nano-priming with ZnO NPs enhanced seed germination and promoted plant growth.

Abstract

Soil salinity is a significant limiting factor in plant growth, particularly in areas affected by salt accumulation. This study aims to analyze the effectiveness of underground drainage in reducing soil salinity through the leaching method and its impact on the growth of spinach (Amaranthus tricolor). The experiment involved applying saline soil mixtures at ratios of 25%, 50%, 75%, and 100% alongside non-saline soil while utilizing underground drainage to expedite the salt leaching process. The parameters observed included pH, electrical conductivity (EC), sodium (Na) content, and plant growth. Observations were conducted at 1, 10, 20, and 30 days, with three replications for each treatment. The results indicated that underground drainage significantly reduced soil salinity levels in a relatively short period. The decrease in salt concentration positively influenced spinach growth, particularly in treatments with lower saline soil mixture ratios. These findings suggest that underground drainage can serve as an effective solution to mitigate agricultural land salinity, thereby enhancing plant productivity.

Abstract

The potential for biodiversity, including a variety of tree, shrub, and bush species, is particularly pronounced in ecosystems characterized by high biodiversity, which influences the soil's capacity to retain water—the greater the species diversity within an ecosystem, its ability to sequester CO2 increases. Lambosir Hill is one of the hills located within the protected forest area of Mount Ciremai National Park (TNGC). This study aimed to assess the level of plant vegetation diversity on Lambosir Hill and examine the relationship between biodiversity and carbon stocks. This study was conducted in Lambosir Hill, Mount Ciremai National Park in Kuningan Province, West Java. This study began in November 2022 and ended in March 2023. Activities related to data processing were carried out at the Land Resources Laboratory, Faculty of Agriculture, National Development University “Veteran” East Java. The study results showed low diversity at the shrub level and moderate at the tree level. The highest carbon stock was found in Sonokeling and the weakest in Hamerang. The land use type, slope, and vegetation composition influence these values’ differences. These results show the importance of permanent vegetation in supporting carbon stocks and ecosystem stability. It is recommended that woody tree vegetation such as Sonokeling be preserved to maintain the sustainability of carbon reserves in this conservation area.

Abstract

Soybean productivity in Indonesia remains relatively low, partly due to declining soil fertility. One approach to address this issue is the application of liquid organic fertilizer (LOF) and phosphate fertilizers, such as SP-36. This study aimed to evaluate the effects of various concentrations of banana corm-based LOF and different doses of SP-36 fertilizer, as well as their interaction, on the growth and yield of soybean plants (Glycine max L.). The research was conducted in Medokan, Surabaya, using a two-factorial Randomized Block Design (RBD) with four levels of LOF concentration (0, 500, 600, and 700 ml/l) and three levels of SP-36 concentration (150, 200, and 250 kg/ha). The observed parameters included plant height, number of pods, percentage of empty pods, seed weight per plant, seed weight per hectare, and fruit set. The results indicated a significant interaction between LOF and SP-36 on plant height 42 days after planting, number of pods, percentage of empty pods, and fruit set. The most effective treatment was the combination of 600 ml/l banana corm LOF and 200 kg/ha SP-36. However, seed weight per plant and hectare did not show a significant effect. This study concludes that the appropriate combination of banana corm LOF and SP-36 fertilizer can significantly enhance soybean growth and yield. It is recommended to use 600 ml/L of banana corm LOF combined with 200 kg/ha of SP-36 fertilizer to optimize plant height, number of pods, and fruit set in soybean cultivation.

Abstract

Rice is one of the primary food commodities as a staple food in Indonesia. Increasing rice production can be done by using certified seeds. Dormancy is one of the obstacles in the rice seed testing process. Eco-enzyme is expected to be used for breaking dormancy and promoting germination in certified rice seed testing. This study aims to determine the optimal concentration and soaking time of Eco-enzyme in breaking dormancy of Inpari 32 HDB rice seeds and to assess the potential of Eco-enzyme in replacing KNO3 0.2% in breaking dormancy of Inpari 32 HDB rice seeds. This research was conducted in the seed quality testing laboratory of UPTD Food Crop and Horticultural Seed Certification, North Sumatra Province, from September to October 2024. The results of the study showed that the use of eco-enzyme with concentrations of 5%, 10%, and 15% and a soaking period of 24 and 48 hours did not show a significant difference or a significantly increased effect on various germination parameters compared to the use of KNO3.

Abstract

Rice (Oryza sativa L.) is the primary staple food crop and a strategic source of carbohydrates for the Indonesian population. In recent years, rice production has declined at both national and local levels due to climate change, land limitations, and pest disturbances. This condition highlights the urgent need for research to develop more efficient and sustainable rice cultivation strategies. This study aimed to determine the interactive effects of planting systems and Paclobutrazol concentrations on the growth and yield of the rice variety Inpari 32. The research was conducted in Ngraho District, Bojonegoro Regency, East Java, using a Split Plot Design with two factors: planting systems (Tegel/traditional, SRI, Legowo 2:1, and modified Legowo) and Paclobutrazol concentrations (0, 600, 700, and 800 ppm). Observed parameters included plant growth and yield components. The results revealed significant interactions between planting systems and Paclobutrazol concentrations on several parameters, including the number of panicles, panicle length, and grain weight per cluster. The best results were obtained with the modified Legowo system combined with 600 ppm Paclobutrazol, which produced yields exceeding 6 tons per hectare. This combination is recommended as an effective cultivation strategy to enhance rice productivity and support sustainable national food security.

Abstract

Long bean (Vigna sinensis L.) is a valuable vegetable commodity recognized for its high nutritional value; however, its production in Indonesia has declined. This decrease can be attributed to improper cultivation techniques. To enhance production, strategies such as NPK fertilization and the application of growth regulators, specifically gibberellic acid (GA3), can be employed to improve yields. The combination of these two methods has the potential to improve both the growth and yield of long beans. This study employed a randomized complete block design (RCBD) with two factors, where each treatment combination was replicated three times. Data analysis was conducted using analysis of variance (ANOVA). This research aims to provide insights and recommendations regarding the most effective doses of NPK fertilizer and GA3 concentrations to enhance growth and yield. Specifically, it seeks to determine the optimal concentration of GA3 that promotes the growth and yield of long bean plants. The combination of NPK fertilizer and GA3 had a significant influence on the growth and yield of long bean plants. The treatment of NPK at 15 g/plant combined with GA3 at 100 ppm resulted in increased plant height, while NPK at 5 g/plant combined with GA3 at 100 ppm led to a higher number of fruits. Additionally, the combination of NPK at 15 g/plant and GA3 at 150 ppm significantly increased pod weight. Furthermore, the individual treatments of NPK at 15 g/plant and GA3 at concentrations ranging from 100 to 150 ppm also positively affected the growth and yield of long bean plants.

Abstract

The model for estimating groundwater availability for plants often overlooks the type of soil and the capacity of plants to absorb water from it. This study employs laboratory soil tests and statistical analyses to examine the relationship between various soil types in Pohuwato Regency and the variations in Groundwater Availability (KAT) levels for rice and corn plants. The results indicate that Andosol and Litosol are the soil types with the highest Field Capacity values in Pohuwato Regency, ranging from 331 mm to 403 mm. Meanwhile, Alluvial and Regosol soil types exhibit the lowest Permanent Wilting Point values in the Pohuwato Regency, ranging from 23 mm to 53 mm. The study results revealed a very high average correlation value of 0.907 between Field Capacity and the Permanent Wilting Point concerning the Groundwater Availability model. The research data, which includes soil characteristics and the Groundwater Availability model for rice and corn cultivation in Pohuwato Regency, can serve as a foundation for strategies that farmers can employ to enhance their future agricultural productivity.
