Abstract

The diversity of plants in a conservation area or forest is important data that can be used as a recommendation in efforts to maintain ecosystem balance, especially in herbaceous and shrubby plants that are rarely studied so that access to plant data is very limited. For this reason, this study aims to identify herbaceous and shrubby plants in the Lemor Botanical Garden Forest Area, East Lombok. This study is a qualitative descriptive study with cruise methods by tracing the exploration route. The findings show that in the area, 21 species from 19 families of herbaceous and shrubby plants were identified. In detail, 13 species from 11 families of herbaceous plants were found with the majority of species having upright, creeping, and epiphytic habitus and 8 species from 8 families of shrubby plants were found, the majority of which had upright habitus. The existence of various herbaceous and shrubby plants plays an important role in maintaining ecosystem stability so that stricter conservation efforts are needed by related institutions to maintain the diversity of existing species.

Abstract

Chili plants have a high selling value when the supply of goods decreases due to late harvests in red chili centers in various regions. This can trigger Indonesian farmers to cultivate more quality chili plants because they have high economic value. This research aims to determine the effect of NPK fertilizer and banana peel liquid organic fertilizer on the growth of red chili (Capsicum annum L) and to assess the impact of the combination of NPK fertilizer and banana peel liquid organic fertilizer on red chili. This study employed an experimental approach, with data collected by assessing plant growth. NPK fertilizer had no discernible effect on the height or quantity of leaves on red chili peppers, but it did have an impact on leaf area, fresh weight, and dry weight. Red chili pepper plants' height, leaf count, leaf area, fresh weight, and dried weight were all unaffected by the application of a liquid organic fertilizer made from banana peels. Red chili pepper plant height and leaf count were not significantly impacted by the combination of NPK fertilizer and liquid organic fertilizer generated from banana peels; but, leaf area, fresh weight, and dry weight were.

Abstract

One of the many advantages of lamtoro is that, due to its high nutrient content, it may be utilized as organic fertilizer. Utilizing POC can help plants meet their nutritional needs and avoid nutrient shortages. The purpose of this study is to ascertain how applying NPK fertilizer and liquid organic fertilizer derived from lamtoro leaves, both independently and together, affects the growth of chili plants. Five treatments using NPK fertilizer and liquid organic fertilizer derived from lamtoro leaves were employed in this study, which employed a completely randomized design with three replications. The impact of treatments on the growth metrics of cayenne pepper plants was assessed using a two-way anova test. The results showed that the application of liquid organic fertilizer (POC) derived from lamtoro leaves had a substantial effect on the number of leaves, leaf area, fresh weight, and dry weight. When NPK fertilizer was applied, plant height, leaf count, leaf area, fresh weight, and dry weight all increased. The application of a mixture of liquid organic fertilizer derived from lamtoro leaves and NPK fertilizer did not significantly affect the cayenne pepper plants' fresh weight, dry weight, number of leaves, leaf area, or plant height.

Abstract

Long beans (Vigna sinensis L.)  require sufficient nutrients for their growth. To increase nutrients, fertilization needs to be carried out using either chemical fertilizers or organic fertilizers. Bokashi is an organic fertilizer that can be applied to agricultural land. Research on the analysis of vegetative growth of Vigna sinensis L due to bokashi and NPK fertilizer treatments has been conducted with the aim of analyzing the effect of bokashi, NPK fertilizer, and the interaction of the two treatments on the vegetative growth of Vigna sinensis L. In this study, a completely randomized design with 2 factors was used. Long bean  growth parameter including number of leaves, leaf length, leaf width and stem length were analyzed using analysis of variance. The results of the study showed that there was an increase in the number of leaves, stem length and leaf length but there was no increase in leaf width after bokashi treatment. NPK fertilizer treatment can increase all growth parameters, The interaction between bokashi and NPK fertilizer did not have a significant effect on the growth parameters of  Vigna sinensis L. Farmers are recommended to use 16 tons of bokashi for 1 hectare of agricultural land combined with 1.5 g of NPK fertilizer for 1 long bean.

Abstract

This study aimed to evaluate the effects of NPK fertilizer and bokashi on the vegetative growth and chlorophyll content of pakcoy (Brassica rapa L.). The objective was to determine both the single and interactive effects of these fertilizers on various growth parameters. The experiment was conducted at the Greenhouse of the Faculty of Agriculture, University of Mataram, from May to July 2025, using a completely randomized design (CRD) with two factors. The treatments consisted of five levels of NPK fertilizer (0–2 g/100 ml water) and five levels of bokashi (0–400 g/polybag). Data were analyzed using two-way ANOVA and Duncan’s Multiple Range Test (DMRT) at a 5% significance level. Results showed that NPK fertilizer significantly affected all growth parameters and chlorophyll content, while bokashi significantly influenced plant height, fresh weight, and dry weight. The interaction between NPK and bokashi significantly affected plant height and biomass but not leaf number, leaf area, or chlorophyll content. The best growth was obtained with 1.5 g NPK/100 ml water combined with 300 g bokashi/polybag. In conclusion, integrating organic and inorganic fertilizers improves nutrient efficiency and pakcoy productivity. These findings recommend integrated fertilization practices to promote sustainable crop production.

Abstract

Cayenne pepper is one of the leading horticultural products in the agricultural sector in Indonesia. In order for plants to grow optimally and produce well, it is necessary to apply silver black plastic mulch and a dose of organic fertilizer. This study aims to determine the growth and chlorophyll content of cayenne pepper plants using black silver plastic mulch and doses of organic fertilizer. The study used a randomized block design with 8 treatment combinations and 3 repetitions. The arrangement of treatments was as follows: M0P0: without mulch + 0 kg/m2, M0P1: without mulch+ 1 kg/m2, M0P2: without mulch+ 1.5 kg/m2, M0P3: without mulch+ 2 kg/m2, M1P0: MPHP + 0 kg /m2, M1P1: MPHP + 1 kg/m2, M1P2: MPHP + 1.5 kg/m2, M1P3: MPHP + 2 kg/m2. The results on plant height and leaf number observations on days 28 and 40 showed that the silver black plastic mulch factor make a real impact. Organic fertilizer significantly affected leaf length on day 40, while the interaction of silver black plastic mulch and dose of organic fertilizer affected leaf length and leaf area on day 40. The best combination in this study was black silver plastic mulch and a dose of 1.5 kg organic fertilizer/m2.

Abstract

Melon is an annual plant, growing creeping with a stem length of about 3 meters. The vegetative and generative growth of melons is influenced by genetic and environmental factors. Environmental factors that affect the growth of melons include the abundance of nutrients in the growing media. Research has been carried out on the effectiveness of vermicompost and NPK fertilizer treatment on melon vegetative growth, with the aim of analyzing the effectiveness of vermicompost in increasing stem length, number, length and width of leaves and stem diameter of melons. effectiveness of NPK fertilizer in increasing stem length, number, length and width of leaves and stem diameter of melons. Effectiveness of the interaction of vermicompost and NPK fertilizer in stimulating melon growth. Growth parameters were measured when the melon was 28, 29 and 30 days after planting, the data obtained was analyzed using Anova. The results showed that vermicomposti is effective in increasing stem length, total and leaf length, but is not effective in increasing leaf width and stem diameter of melons. Application of NPK fertilizer is effective in increasing stem length, total leaves, leaf length, leaf width and stem diameter of melon. The interaction between vermicompost and NPK fertilizer was not effective in stimulating melon growth.
