Abstract

Conventional melon cultivation has limiting factors, one of which is the extreme climate and the provision of sufficient nutrients that are not fully absorbed by plants, which results in greatly varied and inadequate of melon production. The purpose of this research was to determine the type of planting media, the volume of planting media, and combination between the type of planting media and the volume of planting media that was best for the growth and yield of melon plants in a hydroponic system. This research was conducted in the greenhouse of the Lampung State Polytechnic from March to June 2021. The analysis used was Factorial Randomized Block Design (RBD). The first factor was the type of planting media (husk charcoal+sand, cocopeat+sand, husk charcoal only, and cocopeat only). The second factor was the volume of the planting medium (4.3 liter, 7.5 liter, and 9.9 liter). In this study, there were 12 treatment combinations, 3 replications, and analyzed using 5% level of Tukey's test. The variables observed in this study were plant height, number of leaves, leaf width, pollination time, fruit weight, fruit diameter, and fruit flesh thickness. The results showed that the type of planting media, the volume of planting media, and the combination of both did not significantly have a different effect on the observed variables of the growth and yield of melon plants.

Abstract

Sunflowers are plants from the Asteraceae family which are popular as ornamental plants, as well as consumed in the form of microgreens. The problem with microgreen cultivation is that it requires light as a substitute for sunlight and is difficult to imbibition because it has a hard skin. The aims of this study were (1) to obtain the best light spectrum color on the growth and yield of sunflower microgreens, (2) to obtain the best soaking time for sunflower microgreen growth and yields, (3) to obtain the best interaction of light spectrum treatments and soaking time seed. The research method was arranged using a split plot experimental design in a randomized block design with 3 repetitions. The main plot are the light spectrum and the sub plots are the soaking time of the seeds. Variables observed: germination time, germination percentage, germination rate, microgreen height, sample weight per plot. The results showed that the white light spectrum produced the best germination percentage and germination rate, while the blue light spectrum produced the best microgreen height. Seed soaking time of 12 hours produced the best percentage of germination, germination rate, and weight per plot, while soaking time of 24 hours produced the best germination time and microgreen height. Blue light spectrum and 24 hours soaking time produced the best interaction on microgreen height, and weight per plot. White light spectrum and 12-hour soaking produced the best interaction on germination percentage.

Abstract

Curly red chilies are one of the horticultural products that have the potential to be developed because they have high economic value, however the production of curly red chilies in Lampung Province has continued to decline in the last 4 years. One way to increase production value is to increase soil fertility by increasing fertilization. Fertilization is carried out to replace nutrients lost due to rainwater by using fertilizer containing the elements N, P and K, one of which is KNO3 and KH2PO4 fertilizer. The aim of this research is to find out which combination of KNO3 and KH2PO4 is better and to find out whether the single application of KNO3 and KH2PO4 is good for the growth and yield of curly red chili plants. The research used a factorial randomized block design consisting of 2 factors. The first factor is the concentration of KNO3 fertilizer, with 3 levels, namely 3; 4; 5g/l. The second factor is the concentration of KH2PO4 Fertilizer, with 3 levels of 3,5; 4,5; 5,5g/l. Each treatment was repeated 3 times, so there were 9 treatment combinations and 27 experimental units. The variables observed were plant height, stem diameter, number of shoots, fruit weight per plant, number of fruit per plant and root length. Potassium nitrate (KNO3) fertilizer treatment with a concentration of 5 g/l and potassium dihydrophosphate (KH2PO4) 5,5 g/l had a significant effect on plant growth in plant height. Providing potassium nitrate (KNO3) fertilizer with a concentration of 4 g/l and potassium dihydrophosphate (KH2PO4) 5,5 g/l had a significant effect on plant growth including the number of branches and stem diameter. Providing potassium nitrate (KNO3) fertilizer with a concentration of 4 g/l and potassium dihydrophosphate (KH2PO4) 4,5 g/l had a significant effect on plant yields including the number of fruit/plants and the weight of the fruit/plant.

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.
