Abstract

Cayenne pepper (Capsicum frustescens L.) is one of the commodities in Indonesia. The agricultural sector still relies on organic fertilizers to increase the productivity of Cayenne pepper plants. Excessive use of inorganic fertilizers will disrupt the balance of the amount of nutrients in the soil which results in plant metabolism. This study aims to determine the effect of liquid organic fertilizer from vegetable waste on the growth of cayenne pepper plants a completely randomized design (RAL) with 6 levels of treatment (0 ml, 20 ml, 40 ml, 60 ml, 70 ml and 80 ml), was used plants each with 4 repetitions and 4 fertilization times. The plant growth variables observed in this study includ plant height, number of leaves and wet weight. The data obtained were analyzed using one way Anova and further test using Duncan Multiple Range Test (DMRT) at a test level of 0.05. The results showed that the liquid organic fertilizer treatment of vegetable waste had a significant effect on the growth of cayenne pepper plants. Concentration of 80 ml of liquid organic fertilizer gave the best effect on plant height, number of leaves and wet weight among the concentrasi applied.

Abstract

Continuous fertilization with inorganic fertilizers causes the soil to become hard and the balance of nutrients in the soil becomes disrupted so that the soil is unable to provide sufficient nutrients to support normal plant growth. This study aims to determine the effect of compost made from water hyacinth, NPK fertilizer, and their combinations on the growth of cayenne pepper plants, and to determine the best dosage of fertilizer on the growth response of cayenne pepper plants. This study used a completely randomized design (CRD) which consisted of 2 factors. Type of fertilizer and dose of fertilizer with each 4 levels of fertilization and 3 repetitions. The results of data analysis using the ANOVA test showed that the application of water hyacinth-based compost fertilizer; NPK fertilizer; and the combination can increase plant height, number of leaves, leaf area, fresh weight and dry weight on cayenne pepper plants. The DMRT test at the 5% level showed that the best treatment for plant height, wet weight and dry weight was a dose of 400 gr compost and 0 gr NPK, while the best treatment for leaf count was a dose of 200 gr compost and 0.4 gr NPK and the best treatment for Leaf area is a dose of 0 gr compost and 0.4 gr NPK.

Abstract

Tofu dregs have a fairly high protein content because not all of the protein content is decomposed during the production of tofu. Tofu dregs are not put to good use, in fact many people actually dispose of waste which causes environmental pollution. The aim of the study was to determine the effect of NPK fertilizer and tofu dregs organic fertilizer, as well as the combination of these fertilizers on the growth of ground water spinach (Ipomea reptans Poir). The type of research is an experimental 4x4 factorial with a completely randomized design. The first factor was NPK fertilizer which consisted of 4 levels (0, 0.4, 0.8 and 1.2 g/100 ml of water). The second factor was tofu dregs organic fertilizer (0, 50, 100, 150 g/3 kg soil) which consisted of 16 treatment combinations. Test the research hypothesis using TWO WAY ANOVA. The results showed that the application of NPK fertilizer and organic tofu dregs had an effect on fresh weight, plant height, dry weight, and number of leaves. However, it has no effect on leaf area. Application of organic tofu dregs fertilizer at a dose of 150 g/3 kg of soil, and NPK fertilizer 0.4 and 0.8 g/100 ml of water resulted in the best growth of kale plants at the age of 30 days.

Abstract

Fertilizer is very important factor in achieving high productivity, especially in providing essential nutrients. The application of inorganic fertilizers without adding organic fertilizers potentially reduces soil fertility and damages soil structure. This study aimed to determine the effect of burned rice husks, NPK fertilizer application, on the growth of Chinensis bok choy (Brassica rapa L. Subsp. Chinensis). The study employed a completely randomized design (CRD) consisting of 2 factors, with 5 treatment levels. The burned rice husks treatments comprised (0 gr, 90 gr, 110 gr, 130 gr, and 150 gr), while the NPK fertilizer treatments comprised (0 gr, 0.4 gr, 0.6 gr, 0.8 gr, 1.0 gr / 100 ml water). Data were analyzed using an ANOVA test. The results showed that the NPK fertilizer factor significantly influenced all parameters, including plant height, leaf number, wet weight, and dry weight. The burned rice husks factor and the interaction between burned rice husks and NPK fertilizer had no significant effect on all parameters, namely plant height, leaf number, wet weight, and dry weight of the Chinensis bok choy. The optimal treatment for the interaction of burned rice husks and NPK fertilizer "Mutiara 16" was with the N4S4 treatment (combination of NPK Mutiara 1.0 gr/100 ml water and burned rice husks 150 gr) for plant height, leaf number, wet weight, and dry weight parameters, while the optimal treatment for chlorophyll concentration content was with the N3S2 treatment (combination of NPK Mutiara 0.8 gr/100 ml water and burned rice husks 110 gr).
