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

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-ยน. 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.

Abstract

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.

Abstract

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.
