Abstract

NFT hydroponic is a plant cultivation technology that allows plant roots to grow on a shallow nutrient layer on the narrow field. The goal of this study was to evaluate the best NPK 16-16-16 fertilizer concentration and planting media, as well as the combination of the best NPK 16-16-16 fertilizer concentration and planting media, on the growth and yield of pakchoy (Brassica rapa L). This study used a split plot in factorial randomized block design. The first factor is the concentration of AB mix fertilizer as a control at 1400 ppm (N1) and the concentration of NPK fertilizer, namely: 758 ppm (N2), 1000 ppm (N3). The second factor element is the type of planting medium, which consists of 6 media: rockwool (M1), cotton (M2), sponge (M3), fern (M4), charcoal husk (M5), and cocopeat (M6), with 2 repetitions and 18 treatment combinations. Plant height (cm), number of leaves (pieces), leaf width (cm), leaf length (cm), wet weight of sample plants (grams), and dried weight of plants (grams) were the observation variables. In comparison to an NPK nutrient concentration of 1000 ppm, providing an NPK fertilizer concentration of 758 ppm resulted in better growth and yield in the parameters of number of leaves, wet weight, and dry weight of pak choy plants. Using husk charcoal as a planting medium resulted in superior growth and results in the plant height, number of leaves, leaf width, leaf length, and wet weight of pakchoy plants.

Abstract

The use of shade percentage is the main factor as a barrier to sunlight which functions to reduce the intensity of the sun and as a weed control. Liquid biological organic fertilizer is fertilizer that contains microbes and is useful for helping plant growth. The aim of this research is to determine the best shade presentation and concentration of liquid biological organic fertilizer and their combination on the growth and yield of celery plants. This research was carried out from August to November 2023 at the Lampung State Polytechnic Land. This research was a split plot experiment (3 x 3) which was repeated 3 times. The first factor used as the main plot is the percentage of shade which consists of three levels: no shade, 30% shade, 60%. The second factor used as a subplot is the concentration of liquid biological organic fertilizer which consists of three levels: control, 10 ml.l-1, 20ml.l-1. If the results show a significant effect, it will be continued with the Honestly Significant Difference (BNJ) test at the 5% level. Based on the observations result, it can be concluded that there is no good combination between the shade percentage treatment and the concentration of liquid biological organic fertilizer on the growth and yield of celery plants. The shade percentage treatment of 30% gave the best results for all observation parameters tested. Treatment of liquid biological organic fertilizer with a concentration of 10 ml.l-1 gave the best results in all observed parameters except for plant height parameters.

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.
