Abstract

The problem faced by hydroponic farmers in cultivating chili peppers is the lack of an optimal AB Mix nutrient formula that can be synthesized independently using chemical fertilizers readily available in agricultural supply store. This study aims to evaluate the effects of AB Mix nutrient formulation and variety on yield of curly chili peppers (Capsicum annuum L.) in hydroponic system. The experimental design was a Randomized Block Design (RBD) in 2-factor split-plot arrangement with three replications. The main plots consisted of four nutrient formulations. The subplots consisted of plant varieties, which included the Lado Juara F1 variety, the Joker genotype, and Lolay genotype. The result of the study showed that increasin of the concentration of the AB Mix nutrient formulation from N1 to N2 enhanced the number of fruits and the fruit weight per plant, both in the Lado Juara, Joker, and Lolay varieties. However, further increases the concentration of the AB Mix nutrienr formulation from N2 to N3 and N4 decreased the number of fruits and the fruit weight per plant in any of varieties. The use of the Lado Juara variety resulted in higher numbers of fruits and fruit weight per plant compared to the Joker and Lolay genotypes across all AB Mix nutrient formulations with a drip irrigation hydroponic system.

Abstract

Cauli flower is a vegetable from the Brassicaceae family which has high economic value. However, flowering cabbage easily experiences a decline in economic value due to the production of flowering cabbage being attacked by Plutella xylostella. P.xylostella attacks can reach 50-100%, so integrated control is needed to be able to control it effectively and efficiently. Technical and biological cultural controls are the controls applied in this research. The aim of this research was to assess the resistance of flowering cabbage to P.xylostella attacks by applying hedge crops and NPK doses to flowering cabbage. The research was structured using a complete randomized block design with two factors. The first factor is the type of hedge plant, namely spring onions, rampai tomatoes and tagetes, while the second factor is the NPK dosage, namely 100, 200, 300, 400 and 500 kg/ha. The results showed that there was no real interaction between the variables of plant height, flower appearance time, flower weight and P.xylostella attack. However, the border tagetes type was able to suppress P.xylostella attacks. P. xylostella attacks reached 33%.

Abstract

Tomato plants are expected to have an ideal growing environment to optimize their growth and production. Therefore, this study aimed to investigate the effect of various concentrations of biofertilizer, mulch types, and their interactions on growth and production of the Gustavi F1 tomato cultivar. A randomized group design (RGD) arranged factorially was used for the analysis, with the first factor consisting of no mulch (M0), straw mulch (M1), and plastic mulch (M2). The second factor was five biofertilizer concentrations, including 0 ml.l-1 (L0), 5 ml.l-1 (L1), 10 ml.l-1 (L2) 15 ml.l-1 (L3), and 20 ml.l-1 (L4). Data were analyzed using the F test (analysis of variance), and in cases of significant differences, the analysis proceeded with Duncan Multiple Range Test (DMRT) at an α level of 5%. Growth parameters observed in the experiments included plant height at 1 and 3 weeks after planting, while production parameters comprised fruit diameter, the number of fruits per plant, the percentage of fruits experiencing Blossom End-Rot (BER), and fruit weight per plot. The results showed that the use of plastic mulch significantly increased the number of fruits per plant, while the 0 ml.l-1 biofertilizer concentration showed the most effective reduction in the percentage of fruits experiencing BER. Moreover, an interaction between mulch and biofertilizer treatments was observed, particularly in relation to plant height 1 week after planting, the number of fruits per plant, and the percentage of fruits experiencing BER.Keywords— generative, microbes, ground cover, vegetative

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

Shallots (Allium ascalonicum L.) are horticultural crops with great potential to be developed to meet the needs and economic value of the community. Shallot production is influenced by fertilization, both inorganic and organic fertilizers. The objectives of this study were (1) to obtain the best dose of NPK fertilizer for the growth of shallots. (2) to obtain the best concentration of guano liquid organic fertilizer for the growth of shallots. (3) to obtain the best combination of NPK fertilizer doses and guano liquid organic fertilizer concentrations for the growth of shallots. This study was conducted on the horticultural experimental land of the Lampung State Polytechnic from June to August 2024. The research method used was a factorial Randomized Block Design (RAK) with 2 factors and 3 replications. The first factor used NPK fertilizer (N) with 3 levels, namely: 400 kg/ha (N1), 600 kg/ha (N2), 800 kg/ha (N3). The second factor used POC (P) with 3 levels, namely: 2 ml/L (P1), 4 ml/L (P2), 6 ml/L (P3). Each treatment was repeated 3 times so that there were 9 treatment combinations and 27 experimental units. The results showed that the application of NPK fertilizer at a dose of 600 kg/ha showed the best results for all observation parameters except plant height and number of leaves. The application of POC Guano did not show significantly different results for all observation parameters. There was no best combination between NPK fertilizer and POC Guano treatment for all observation parameters.

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.
