This research aims to get the best AB-mix nutritional formulation for growth and production curly red chili plants; to get the best concentration of foliar fertilizer for growth and production of curly red chili plants; to find out interactions between the use of AB-mix nutritional formulation and foliar fertilizer on growth and curly red chili plants. This research uses a split plot consists of 2 factors with 3 replications. The first factor is the AB mix (F) nutritional formulation with 4 levels treatments namely F1 (P 75, K 402, Ca 150, Mg 60, 90 ppm), F2 (P 105, K 432, Ca 180, Mg 90, S 120 ppm), F3 (P 135, K 462, Ca 210, Mg 120, S 150 ppm) and F4 (P 165, K 492, Ca 240, Mg 150, S 180 ppm). The second factor is foliar fertilizer (D) with 3 levels, namely 3, 5 and 7 g.l-¹. The best AB-mix formulation is found in F4 on all observation parameters. The best concentration foliar fertilizer is D3 on the number of main branches, fruit weight planting and number of fruit. There is AB-mix nutritional formulation and Provit maxi Foliar Fertilizer did not produce any significant interactionsreal in all observation parameters.

In vitro culture method can be used to obtain superior chrysanthemum seedlings. The objective of this research is to determine the origin of the cuttings and the best type of planting media for the growth of chrysanthemum seedlings at acclimatization stage. Data collection for this research was carried out in March-May 2024 at Lampung State Polytechnic Ornamental Plant Net House. This research used a Randomized Block Design (RAK) with two factors, namely origin of cuttings seedlings and type of planting medium with 6 treatment combinations which were repeated 4 times. The first factor are origin of the cutting seedlings (P1) top of the plant, and (P2) middle part of the plant. Meanwhile, the second factor are type of planting medium (M1) husk charcoal, (M2) goat pen compost, and (M3) cocopeat. The results of this research show that the use of shoot cuttings with cocopeat and charcoal husk planting media showed better results in all parameters.

Cauliflower is a vegetable with high economic value. However cauliflower production was decrease caused by crop failure resulting, pest and deseasse attack. Decrease of Cauliflower production related to soil fertility. One of attempts to overcome this problem is combining NPK fertilizer and setting of plant spacing to increase cauliflower production in Indonesia. The aims of this research is Firts: Determine the most effective dose of NPK fertilizer for growth and yield cauliflower, Seccond: Finding the optimal plant spacing to support growth and yield of cauliflower, and Third: indentifying best combinations of NPK fertilizer dosage and plant spacing to increasing growth and yield of cauliflower production. This research used a factorial Randomized Group Design (RAK) by two factors: NPK fertilizer dose (0 g/plot, 5 g/plot, 10 g/plot dan 15 g/plot), plant spacing (40 x 45 cm, 50 x 45 cm, and 60 x45 cm). Results of this research show that aplication doses of NPK fertilizer provides best results at an NPK fertilizer dose of 10 g/plot. Application of plant spacing did not show significant differences throughout observed of all parameters. Additionally, no interactions from combination of NPK fertilizer dosage and plant spacing cauliflower.

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.

Efektivitas Pemberian Konsentrasi Pupuk Daun Growmore (32-10-10) dan Jenis Media Tanam Terhadap Pertumbuhan Tanaman Anggrek Dendrobium Airey Peach x Dendrobium discolor

Orchids are the largest type of flower in the Orchidaceae family of ornamental plants, and this ornamental plant has high economic value. The problem in cultivating orchids is that orchid plants tend to grow slowly. The aim of this research was to determine the most effective concentration of Growmore leaf fertilizer (32-10-10); the best type of planting medium for orchid growth; and to find out the best combination of Growmore foliar fertilizer (32-10-10) with the type of planting medium. This research was carried out using a factorial randomized block design (RBD) with 2 factors and repeated 3 times. The first factor is concentration of Growmore leaf fertilizer (32-10-10) with concentrations of 1 g.l^-1 (P1), 2 g.l^-1 (P2), 3 g.l^-1 (P3), and 4 g.l^-1 (P4). The second factor is the type of planting medium consisting of a mixture of wood charcoal and cocopeat (M1), ferns with wood charcoal (M2), and ferns with cocopeat (M3). The results of study showed that the effectiveness of giving Growmore leaf fertilizer (32-10-10) at concentrations of 2 g.l^-1, 3 g.l^-1, and 4 g.l^-1 it showed better results on the observed variables of plant height, increase in number of leaves, and longest leaf length compared to 1 g.l^-1. The use of fern + wood charcoal planting media showed better results in the longest root length observation variable. There is no best combination between Growmore foliar fertilizer (32-10-10) and the type of planting media for the growth of Dendrobium Airey Peach x Dendrobium discolor orchids.

In increasing kailan productivity, organic mulch can be used through the application of sawdust mulch and fertilization through fertilizer applications. This study aims to determine the concentration of LOB and the thickness of sawdust mulch and the best combination of LOB concentration and sawdust mulch thickness on the growth and yield of kale plants. This study was conducted in May until July 2024, on the Lampung State Polytechnic land, using a Randomized Block Design (RBD) with two treatment factors, namely: The first factor is the concentration of organic fertilizer LOB consisting of 4 levels, namely 0 ml.1^-1 (P0), 15 ml.1^-1(P1), 20 ml.1^-1(P2), 25 ml.1^-1(P3). The second factor is the thickness of sawdust mulch consisting of 3 levels, namely 2 cm mulch thickness (M1), 3 cm mulch thickness (M2), 4 cm mulch thickness (M3). The data obtained were analyzed using analysis of variance. The results showed that the combination of two factors did not show a significant effect on all observation parameters. The sawdust mulch thickness treatment showed a significant effect on plant height but did not have a significant effect on the other parameters.
