Abstract

Organic chili cultivation has become a necessity nowadays as awareness increases about the dangers of chemical residues used in conventional cultivation practices. Chili is one of three main of vegetables commodities in Lampung. However, pepper yellow leaf curl disease is still a major obstacle faced by farmers to increase chili productivity. Therefore, the aim of this research is to study the characteristics of symptoms and the incidence rate of pepper yellow leaf cull disease of Capsicum annuum L. and Capsicum frutescens in organic cultivation practice. The results shown that the characteristics or early symptoms of pepper yellow leaf curl disease on chilies are yellowing of young leaves, mosaic and malformation which are found in C. annuum L and C. frutescens. The intensity of disease attacks on chili plants by giving POC from the Mimosa pudica roots (PM) gave positive efect with an average low attack intensity in the 8th week, namely 32% compared to giving POC from bamboo roots (AB) with an average attack intensity 45.5%. This indicates that POC from the roots of Mimosa pudica (PM) is capable of being a bioprotectant for chili plants. The application of POC type 3 also provided a positive response with a low intensity of pepper yellow leaf curl disease on C. frutescens.

Abstract

In 2020, lettuce production in Indonesia was only 101,129 tons, falling short of the market need of 300,204 tons. Fertilizer effects lettuce plant growth and production. The aim of this study was to establish the optimal dosage of cow manure and NPK fertilizer for lettuce plant development and productivity. The research was conducted on agricultural land in Rawa Selapan Village from April to June 2024. This study used a Randomized Block Design (RAK) with two components and three replications. The first factor, the dose of cow manure, had three levels: without cow manure (P0), 100 g/plant (P1), and 200 g/plant (P2). The second factor, the dose of NPK fertilizer, also had three levels: without NPK fertilizer (N0), 2 g/plant (N1), and 4 g/plant (N2). The collected data were examined using analysis of variance, and if there was a significant difference, a 5% BNT test was performed. According to the study's findings, fertilizing with cow manure at a dose of 200 g/plant resulted in better growth and results in the parameters of plant height, number of leaves, wet weight of plots, wet weight of samples, and dry weight of lettuce roots compared to treatments without manure and cow manure at a dose of 100 g per plant. The application of a dose of NPK fertilizer 4 g/plant resulted in good growth and results in the parameters of plant height, leaf width, wet weight per plot, and wet weight of lettuce roots when compared to treatments without NPK fertilizer and NPK fertilizer 2g/plant. No interaction was found between the combination of cow manure and NPK fertilizer dosages.

Abstract

Mustard greens are one of the most popular vegetables in Indonesia, leading to an increasing demand each year, though production levels remain unstable. Among its varieties, pagoda mustard (Brassica narinosa L.) has gained popularity due to its nutritional benefits. Proper plant spacing and NPK fertilizer dosage are believed to improve crop yield. This study aimed to: 1) determine the effect of plant spacing on the growth and yield of Pagoda mustard (Brassica narinosa L.), 2) determine the effect of NPK 16-16-16 fertilizer rates on the growth and yield of Pagoda mustard (Brassica narinosa L.), and 3) determine the interaction effect between plant spacing and NPK 16-16-16 fertilizer rates on the growth and yield of Pagoda mustard (Brassica narinosa L.). The research was conducted in Budi Lestari Village, Tanjung Bintang District, South Lampung, from November to December 2024, using a factorial randomized block design with two factors: plant spacing—20 x 20 cm (J1), 30 x 30 cm (J2), and 40 x 40 cm (J3)—and NPK fertilizer dosage—100 kg/ha (N1), 200 kg/ha (N2), and 300 kg/ha (N3). The results showed that a 40 x 40 cm spacing produced the best results for the number of leaves at 28 days after planting, plant dry weight, and root dry weight. A spacing of 20 x 20 cm produced the highest yield per plot. The 200 kg/ha NPK dosage gave the best performance for leaf number, plant dry weight, and root dry weight. The combination of 40 x 40 cm spacing and 200 kg/ha NPK fertilizer resulted in the highest root dry weight.

Abstract

This study aimed to evaluate the growth and yield response of kailan (Brassica oleraceae var. Albograba) to various plant spacings and growing media under a hydroponic NFT system. The experiment was conducted from September to November 2024 using a split-plot randomized block design with two factors: plant spacing (10 × 10 cm, 15 × 15 cm, and 20 × 20 cm) and growing media (cocopeat, rice husk charcoal, and rockwool), resulting in nine treatment combinations with three replications. Observed variables included plant height, number of leaves, leaf width, leaf length, fresh weight per plant, fresh weight per plot, and dry weight per plant. The results showed that plant spacing significantly affected plant height and fresh weight per plot, with the closest spacing (10 × 10 cm) yielding the highest biomass accumulation per plot. Growing media had a significant effect on all measured variables, where cocopeat consistently produced the highest values for plant height, leaf growth, fresh weight, and dry weight, followed by rice husk charcoal, while rockwool resulted in the lowest performance. No significant interaction was found between plant spacing and growing media. Overall, the study demonstrates that a spacing of 10 × 10 cm combined with cocopeat as the growing medium provides the most optimal growth and yield in hydroponic kailan cultivation.

Abstract

The use of hydroponic systems is often constrained by high costs due to the relatively expensive price of AB Mix fertilizers. This study aimed to determine the optimal AB Mix nutrient concentration for the growth and yield of two melon varieties, as well as to examine the interaction between AB Mix nutrient concentration and the two melon varieties used. The experiment was arranged in a Randomized Complete Block Design (RCBD) with a split-plot pattern consisting of two factors: AB Mix nutrient concentration (1200, 1500, 1800, and 2100 ppm) as the main plot, and melon varieties Inthanon and Honey Globe as subplots. Data were analyzed using analysis of variance (ANOVA), and significant differences were further tested using the DMRT at a 5% significance level. The results showed that an AB Mix nutrient concentration of 1800 ppm resulted in better growth and development of melon plants compared to other concentrations. Variety V2 (Honey Globe) also exhibited the best performance, particularly in terms of leaf width, fruit diameter, and fruit weight. In addition, there was an interaction between AB Mix nutrient concentration and melon variety affecting plant height at 14 and 21 days after planting (DAP) as well as fruit diameter, indicating that plant responses depended on the combination of both treatments.
