Abstract

The productivity of potatoes in Indonesia is relatively low and unstable caused by unsuitable enviromental and soil conditions and bad cultivation system. This research was conducted to study the effect of NPK fertilizer dosages and soil order to soluble K, K Uptake, and yield of seed potatoes (Solanum tuberosum L.). The experiment design used a factorial randomized block design with two factors and three replication. The first factor was NPK fertilizer dosages with five levels (0, 25, 50, 75, 100% recomendation dosages) and the second factor was soil orders with two levels (Andisols and Inceptisols). The results of experiment showed that the interaction effect between NPK fertilizer dosages and soil orders had significantly effect to soluble K and K Uptake. There were independent effect of NPK dosages to diameter of potatoes tuber and independent effect of soils order to yield of seed potatoes. Andisols with 25% NPK and Inceptisols with 50% NPK were the best combination treatment to increase soluble K while treatment Inceptisols with 25% NPK was the best combination treatment to increase K Uptake. Dosages of 25% NPK was the best treatment to increase diameter of potatoes tuber while Inceptisols was the best treatment to increase yield of seed potatoes.Keywords : NPK Fertilizer Dosages, Andisols, Inceptisols, Potassium, Potatoes

Abstract

Sand-mining can damage to physical, chemical and biological soil properties. Land reclamation is one of method that can be use to solved that problem. Adding soil ameliorant and revegatation are known can improve soil productivity. The objective of this study was to determine the effect of soil ameliorant, which is organic fertilizer and biofertilizer in improving soil organic-C and root infection of dragon fruit (Hylocereus costaricencis L.) by AMF on soil originated from Sand Mining, Sumedang, Indonesia. Greenhouse experiment was conducted at Faculty of Agriculture, Universitas Padjadjaran from December until June 2013. The experiment used was Factorial Randomized Block Design consist of two factors and three replications. The first factor was biofertilizer which consist of: without biofertilizer, AMF and AMF + MHB (Mychorriza Helper Bacteria). The second factor was organic fertilizer that consist of: without organic fertilizer, chicken manure, goat manure, cow manure, rabbit manure, cocopeat and Organic Granule Fertilizer (each 5 kg / pot). Results of experiment showed that there was interaction effect between organic fertilizer and biofertilizer in improving soil organic-C. There was no interaction effect between organic fertilizer and biofertilizer to root infection.

Abstract

Hydroponics is one of the urban farming techniques that can be used to improve crop yield. Nowadays, the supply of all nutriens in hydroponics, particulary phosphate only derived from inorganic fertilizers. Application of arbuscular mycorhiza fungi (AMF) as bioagent may help plants to fill its nutrient need, especially phosphate. This study aimed to find out the best concentration of phosphate fertilizer to be applied to the hydroponic Ebb-flow system model. The stage was to test several vegetable plants with various concentrations of phosphorus (0, 20, 40, 80 ppm) on the Ebb-flow hydroponic system. Vegetables used were romaine lettuce, red lettuce, and kale. Interaction was found between vegetables and the variety of phosphate concentrations and the root colonization by AMF, and phosphate uptake. The AMF applications on the hydroponic Ebb-Flow system model reduced phosphate fertilizer need by 40 ppm (50%), on red lettuce 0 ppm (100%), and on kale 20 ppm (25%). Besides lowered phosphate doses, such applications also increased the plant yield.

Abstract

Low soil fertility was a major factor limiting national black soybean productivity. Black soybean, a functional food crop rich in isoflavones, requires effective fertilization to enhance growth.Environmentally friendly alternatives such as vermicompost and biofertilizers offer sustainableoptions. This study aimed to evaluate the effects of vermicompost and biofertilizers on rootcolonization by arbuscular mycorrhizal fungi (AMF), phosphorus (P) uptake, and black soybeangrowth, and to identify the most effective treatment. The experiment was conducted from December2024 to February 2025 in a plastic house at Bale Tatanen, Faculty of Agriculture, UniversitasPadjadjaran, Jatinangor, West Java. A Randomized Group Design with 12 treatment combinations andthree replications was used. Treatments consisted of 5 and 10 tonnes ha⁻¹ of vermicompost combinedwith either AMF or nitrogen-fixing bacteria (NFB), which were appllied to the planting holes. Datawere analyzed using ANOVA and the Scott-Knott test at a 5% significance level. Observed parametersincluded AMF root colonization, P uptake, plant height, number of leaves, chlorophyll index, leaf area,and dry weights of roots and shoots. The results showed that vermicompost and biofertilizersincreased AMF colonization, P uptake, plant height, leaf number, chlorophyll index, and shoot dryweight. The application of 5 tonnes ha⁻¹ vermicompost combined with AMF was the most effectivetreatment. This study provided useful recommendations for vermicompost and biofertilizerapplication to support soil fertility improvement and black soybean growth on marginal lands.
