Abstract

One of the most popular vegetables is the long bean (Vigna sinensis L.). Due to the presence of Rhizobium bacteria nodules in its roots, long bean plants are considered soil enrichers. Liquid organic fertilizer from goat urine is highly soluble in soil and contains essential nutrients crucial for soil fertility. This study aims to ascertain the best fertilizer dose for plant development as well as the effects of goat urine organic fertilizer, NPK fertilizer, and their combination on the growth of long bean plants (Vigna sinensis L.). A completely randomized design was used to perform the study as an experiment (CRD). With the aid of SPSS for Windows 25, two-way ANOVA was used for data analysis. Post hoc analyses were performed using DMRT and were allowed if the p-value (sig) was less than 0.05 or if the computed F value was greater than the tabular F value. The combination of goat urine organic fertilizer (POC) and NPK fertilizer did not substantially alter the development of long bean plants, according to the findings of the ANOVA study on the plant height parameter. Significant variations were seen, nonetheless, for other metrics as chlorophyll content, wet and dry weights, leaf area, and number of leaves. At the 5% significance level, the impact of treatments on plant height metrics showed that either the alternative hypothesis, H1, or the null hypothesis, H0, was accepted. Thus, it can be said that there is a strong interaction between the growth of long bean plants and the combination of NPK fertilizer and goat urine organic fertilizer (POC).

Abstract

An key factor in promoting the growth and development of plants is fertilizer. Both organic and inorganic fertilizers can be used for fertilization. If inorganic fertilizers are applied over an extended period of time without the incorporation of organic matter, the soil's quality may be compromised, leading to suboptimal plant development. The purpose of this study is to ascertain the optimal fertilizer dose for purple eggplant growth response, as well as the effects of NPK fertilizer, liquid organic fertilizer made from vegetable waste, and a combination of both on the vegetative growth of purple eggplant plants. A two-factor Complete Random Design was employed in this study, with three replicates and five treatment levels for each of the liquid organic fertilizer made from vegetable waste and NPK fertilizer treatment. The Anova two-way test was used to examine the data, and then the DMRT test was performed. The application of liquid organic fertilizer made from vegetable waste and the combination of the two fertilizers had a real effect on plant height, leaf area, wet weight, and dry weight but no real effect on the number of leaves, according to the results. On the other hand, the application of NPK fertilizer had a real effect on plant height, number of leaves, leaf area, wet weight, and dry weight. The results of the DMRT test (5%) indicated that the optimal dosage for plant height, wet weight, and dry weight was 1.5 grams of NPK and 10 ml of liquid organic fertilizer made from vegetable waste; for the number of leaves, it was 1.5 grams of NPK and 2 grams, and for the area of leaves, it was 1 gram of NPK.

Abstract

Macronutrients (N, P, and K) are essential for plants. Plants that are deficient in any of these elements may produce less in terms of both quantity and quality. The purpose of this study is to ascertain how pakchoy (Brassica rapa L.) growth is impacted by the concentration of liquid organic fertilizer from rice washing water and NPK fertilizer. This study used a completely randomized design with two components and five treatment levels: liquid organic fertilizer treated with rice washing water (0 ml, 10 ml, 20 ml, 30 ml, and 40 ml) and NPK fertilizer treatment (0 g, 0.5 g, 1 g, 1.5 g, and 2 g). Anova was used to examine research data. The study's findings demonstrated that NPK fertilizer significantly impacted plant growth in terms of plant height, leaf area, number of leaves, and wet and dry weight. Plant height, the quantity of leaves, and plant wet weight were not significantly affected by rice-washed liquid organic fertilizer, but leaf area and dry weight were. The growth of pakchoy was not significantly impacted by the combination of liquid organic fertilizer from rice washing water and NPK fertilizer.

Abstract

Applying fertilizer can increase spinach productivity. Fertilization is necessary because the nutrients in the soil can be reduced as a result of being absorbed by plants continuously. For plants to thrive, there must be an adequate supply of nutrients. The purpose of this study is to ascertain the impact of roasted rice husk and NPK fertilizer, as well as the ideal ratio of the two to promote spinach development. A fully randomized design comprising two components, five treatment levels, and three replications was employed in this investigation. The plant height, number of leaves, leaf area, wet weight, and dry weight were all significantly impacted by the NPK fertilizer element, according to the Anova data. At 18 days after planting, the factor of burnt rice husk significantly affected plant height; however, at 35 days after planting, it had no significant influence. The interaction of NPK fertilizer and roasted rice husk had no significant effect on all observation parameters. The best treatment on plant height, leaf area, and wet weight was the dose of 200 g of roasted rice husk and 1.6 g NPK fertilizer, the best treatment on the number of leaves was the dose of 50 g of roasted rice husk and 1.6 g NPK fertilizer, the best treatment on dry weight was the dose of 100 g of roasted rice husk and 1.6 g NPK fertilizer.

Abstract

Beautiful beetles are a group of insects that play an important role in maintaining ecosystem balance, ecotourism and education. Suranadi Nature Park, as one of the conservation areas in Indonesia, has great potential in maintaining the biodiversity of these insects. However, information on the dispersion pattern of beautiful beetle species in this area is still very limited so this research is important. The data collection method was carried out by survey, by capturing and directly documenting the beetles encountered during the exploration of the forest of TWA Suranadi. Data collection was carried out in June 2024 on the edge, middle of the forest and waterways. The samples obtained were brought to the Biology Education laboratory of FKIP Unram for identification. The results showed that the distribution pattern of beautiful beetles in Suranadi Nature Tourism Park has three distribution patterns, namely group distribution patterns of 21%, Uniform 72% and random distribution patterns 7%. In conclusion, the distribution pattern of beautiful insects in Suranadi Nature Park is different. The dominant uniform distribution pattern, then the group distribution pattern and the least random distribution pattern.
