Abstract

One source of nutrients that influences how a plant grows and produces is fertilizer. fertilization that is possible with both inorganic and organic fertilizers. The purpose of this study is to ascertain how the development of bok choy is impacted by vermicompost, NPK fertilizer, and their combination. Design using RAL two components with five fertilization levels each, repeated three times, such that the experimental unit employed up to 75 plants. The first factor is the dose of vermicompost organic fertilizer consisting of K 0 = 0  gr (control), K1  = 50 gr, K2 = 100 gr, K3 = 150 gr and K4 = 200 gr. The second factor is the dose of NPK fertilizer (16:16:16) consisting of N 0 = 0 gr (control), N 1 = 0.3 gr, N2 = 0.6 gr, N3 = 0.9 gr and N4  = 1.2 gr. The ANOVA test was used to evaluate the data. The findings revealed that the vermicompost treatment had no appreciable impact on the plant's height, number of leaves, leaf area, wet weight, or dry weight characteristics. The use of NPK fertilizer has a sizable influence on plant properties such as height, leaf count, leaf area, wet weight, and dry weight. Vermicompost and NPK fertilizer together have a considerable influence on the metrics of plant height, leaf count, wet weight, and dry weight.

Abstract

Melon is a short-lived dicot, that growing up on the ground or on bamboo stakes. Vegetative growth and melon production rate are influenced by internal and external factors. Research has been carried out on the analysis of melon growth due to the application of silver black plastic mulch and cow manure compost in 2023. This study aims to analyze the effect of application of silver black plastic mulch on melon growth; application of cow manure compost on melon growth; interaction of application of silver black plastic mulch and cow manure compost on melon growth. The study was designed in two factors, namely the application of silver black plastic mulch as the first factor and the dosage of cow manure compost as the second factor. The results of the study were: there was an increase in plant height, number of leaves, leaf length and width of melon leaves due to application of silver black plastic mulch; there was an increase in plant height, number of leaves, length of melon leaves due to application of cow manure compost, but the application cow manure compost did not increase the length of melon leaves; there was no increase in all growth parameters measured due to the interaction of silver black plastic mulch and cow manure compost application

Abstract

This research aims to determine the species of ferns (Pteridophytes) and to determine the relationship patterns of ferns (Pteridophytes) in the Suranadi Natural Tourism Park Area, West Lombok Regency. The research was conducted from June to July 2023. This type of research is descriptive research using the roaming method, with a roaming area of 52 Ha. The samples of this research were ferns (Pteridophytes) found at the research location. Data collection techniques are carried out by means of observation, identification and documentation. The results of the research show that in the Suranadi Nature Tourism Park there are 3 orders, 10 families, 16 genera and 33 species of ferns. The fern grouping pattern is depicted in the form of a dendogram, the dendogram was created using the NTSYS application. In this study, the closest level of relationship is species Christella parasitica with species Christella subpubescens namely 94%. Meanwhile, the ferns with the furthest degree of relationship are the species of the family Polypodiaceae and species of the family Thelypteridaceae, with a kinship level of 50%.
