Abstract

Podzolic red-yellow soil has the potential for the development of plantation crops. Efforts to improve thefertility of Podzolic red-yellow soil include the application of both inorganic and organic fertilizers.Rubber plants are one of the important plantation crops in Indonesia. Rubber seedling is a crucial stagethat significantly determines latex production. Excessive use of inorganic fertilizers can have a negativeimpact on the environment, especially water pollution, thus it needs to be substituted with organicfertilizers. The aim of this research is to find the lowest dose of Azolla pinnata compost that providesgrowth equivalent to a dose of NPK 20 grams/polybag. This study used a completely randomized design(CRD) non-factorial with 6 treatments consisting of control: NPK 20 g/polybag, P1: Azolla pinnatacompost 100 g/polybag, P2: Azolla pinnata compost 200 g/polybag, P3: Azolla pinnata compost 300g/polybag, P4: Azolla pinnata compost 400 g/polybag, P5: Azolla pinnata compost 500 g/polybag. Eachtreatment was repeated four times. The observed parameters are seedling height, stem diameter, leaf chlorophyll, and seedling dry weight. The obtained data were analyzed using variance analysis, and ifthere was a significant effect, a difference test was conducted using LSD (Least Significant Difference) ata 5% level. The research results showed that the treatment of 200 grams/polybag was the lowest dose thatprovided growth equal to NPK 20 grams/polybag in the parameters of plant height, stem diameter,number of umbrellas, and dry weight of rubber seedlings. The use of Azolla pinnata compost startingfrom 200 grams/polybag can already replace NPK 20 grams for rubber seedling cultivation, especially inPMK soil.

Abstract

The productivity of rubber plants in Indonesia is relatively low, so efforts to increase productivity need to be made, one of which is by improving cultivation technology, the limitation of nutrients in the soil of former gold mines is overcome by providing vegetable waste compost. Vegetable waste compost has a C-organic content of 28.89%, N 1.57%, P 1.39%, K 0.69%. This study aims to determine the effect of vegetable waste compost on the growth of rubber seedlings on the soil of former gold mining land. The research was conducted at the Sukaharja Experiment Garden, Gg. Pandan, from April to July 2024. The study used a non-factorial Complete Random Design (RAL) consisting of 5 groups and 5 replicates, there were 25 experimental units, each experiment consisted of 3 samples so that the total number of samples was 75 samples. The parameters observed were the height of the seedlings, the diameter of the stems, the number of umbrellas, and the dry weight of the seedlings. The data is statistically analyzed with Analysis of Variance (ANOVA), if obtained has a real effect, then the Duncan Multi Range Test (DMRT) is continued at the level of 5%. The results of the fingerprint showed that the treatment of vegetable waste composting had a real influence on the variables of seedling height, stem diameter, number of umbrellas, and root volume. The results of the DMRT test at 5% level show that treatment with a dose of vegetable waste compost of 640 g/polybag is able to provide good growth for the growth of rubber seedlings.

Abstract

The use of inorganic fertilizers in cocoa nurseries has a negative impact on environmental sustainability, so it is necessary to optimize organic fertilizers that are proven to be environmentally friendly and can be used sustainably. Therefore, an alternative is needed to substitute organic fertilizers, namely the use of Azolla pinnata compost. Azolla pinnata compost has the potential to substitute the use of inorganic fertilizers N, P, and K because the nutrient content is already available in Azolla pinnata compost. This study aims to determine the minimum dose of Azolla pinnata compost that provides the same growth as inorganic fertilizer (NPK) in enhancing the growth of cocoa seedlings in PMK soil. This study used a non-factorial Completely Randomized Design (CRD) consisting of 5 treatment levels with 4 replications. So that 20 experimental units  were obtained. Each treatment consisted of 3 plant samples so that 60 plants were obtained. The treatments consisted of K0: NPK fertilizer 24 g polybag-1, K1: Azolla pinnata compost 100 g polybag-1, K2: Azolla pinnata compost 150 g polybag-1, K3: Azolla pinnata compost 200 g polybag-1, K4: Azolla pinnata compost 250 g polybag-1. The data obtained from the research results were analyzed statistically using Analysis of Variance (ANOVA). If the treatment had a significant effect, it was continued with the Least Significant Difference (LSD) test at the 5% level using the DSAASTAT application. The results of the analysis of variance showed that the treatment of inorganic fertilizer (NPK) and Azolla pinnata compost had a significant effect on the variables of plant height, stem diameter and leaf chlorophyll. The results of the 5% LSD test showed that treatment with a dose of Azolla pinnata compost of 200 g polybag-1could provide the same growth as the administration of inorganic fertilizer (NPK) with a dose of 24 g polybag-1in cocoa seedlings in PMK soil.
