Abstract

Rice is an important commodity in Indonesia because rice is the main source of carbohydrates for the Indonesian. Rice production in Indonesia relies on lowland rice, but the productivity of lowland rice is decreasing. One of the efforts to increase rice national production is utilizing upland rice plants. The problem with upland rice is its low productivity. Nitrogen-fixing biological fertilizers can be used to increase the productivity of upland rice plants. The effect of different doses of nitrogen fertilizer and nitrogen fixing bacteria with different carrier materials on the growth and yield of upland rice in Inceptisols Jatinangor was studied. Randomized block design with two factors: the recommended dose of urea fertilizer (100% and 50%) and the nitrogen-fixing bacteria factor with different carriers (compost, rice bran, and Azolla powder) were applied as an experimental design. The experimental results showed that the interaction of nitrogen fertilizer dose and nitrogen-fixing bacteria with different carriers had no significant effect on plant height, number of panicles, root shoot ratio, and weight of 1000 grains of upland rice plants. Application of nitrogen-fixing bacteria with compost, bran, and Azolla powder as carriers was able to increase the average weight of the filled grain higher than the control.

Abstract

The use of N2-fixing bacteria and growth hormone-producing rhizobacteria delivers nitrogen, enhances nutrients absorption by plants, and reduces the usage of inorganic fertilizers. Implementing biofertilizer in the hydroponic system as a means to reduce application of synthetic nutrient is recently in interest due to economic, food safety, and sustainability factors. This study determines the effects of biofertilizer dose on tomato yields in the hydroponics system. A randomized block design was utilized that consisted of seven treatments, namely 100% inorganic fertilizer and 0% biofertilizer (control), and various doses of inorganic nutrient combined with 25%, 50%, 75%, and 100% biofertilizer. The result illustrated that the application of biofertilizer augmented the population of endophytic bacteria, Azotobacter sp., Azospirillum sp., phosphate solubilizing bacteria, and nitrogen content. The distinct combination of biofertilizer did not alter the phosphorus and potassium content compared to control samples however resulted in superior tomato grade. The 50% inorganic fertilizer and 100% biofertilizer combination amplified the weight of the fruit by 36% compared to the control. This finding indicates that the application of biofertilizers in the hydroponic system for tomato plants is not only beneficial in minimizing the dosage of inorganic fertilizers but also enhancing the fruit quality.

Abstract

The status of nutrients N, P, and soil organic content in corn cultivation is an important thing that needs to be pursued to improve soil quality. One such effort is through mycorrhizal inoculation and the application of appropriate compost. The aim of this study was to evaluate the effectiveness of arbuscular mycorrhizal fungi (FMA-1) and compost types on soil chemical properties (C/N, C/P), degree of root infection, and corn pruning weight (Zea mays) on Inceptisols. The experiment used three replications of a factorial randomized block design (RBD). The first factor of FMA inoculation: FMA 0 gpot-1, FMA-1 20 g/pot; Mycofer 20 g/pot, and mix (FMA-1 10 g/pot + FMA mycofer 10 g/pot), and the second factor is compost application: 0 g/pot; 75 gpot-1 rabbit hutch compost; 75 g/pot market waste compost and rabbit cage compost 37.5 g/pot + market waste compost 37.5 g/pot). The results showed that there was no interaction between AMF inoculation and the application of compost which affected soil chemical properties, degree of root infection, and dry weight of corn plants. However, independently AMF affects the degree of root infection, and compost affects the dry weight of corn plants. A dose of 20 g/pot FMA and mixed FMA inoculation (FMA and Mycofer) significantly increased the degree of root infection compared to the control treatment. The application of all types of compost showed a significant increase in corn plant dry weight compared to the control. Doses of 75 g/pot of market waste compost tended to increase plant dry weight higher than other treatments with an addition of 32.07 g each plant.

Abstract

Strawberries in tropical West Java are cultivated intensively in potted soil but the substrate condition received less attention. The objective of this descriptive research was to evaluate the chemical and macronutrient profile in potted-soils for strawberry cultivation, and to determine beneficial microbes’ population in root-free bulk soil and rhizosphere of potted-strawberry.  The soil samples collected from 12-months and one-month-old potted strawberry; both contained Inceptisols soil order with 10 t/ha and 25 t/ha manure respectively. The proximate analysis was performed using Association of Official Analytical Chemists Method. The microbial enumeration was performed by Serial Dilution Plate Method in specific medium. The results showed that potted soils were not saline, but slightly acid, low in organic carbon and high in cation exchange capacity. The soil reactions were suitable for strawberry but the electrical conductivity was too low for strawberry growth. The potted soils have low to very low carbon to nitrogen ratio, but high in total nitrogen and very high in potential P2O5 and K2O. The population of phosphate-solubilizing bacteria, nitrogen-fixing Azotobacter, total bacteria and total fungi in old potted soil were low; but its counts were increased in manure-treated potted soil. The ratios of bulk soil to rhizosphere microbial count were only 1.0-1.25. The study verified that the doses of organic matter should be increased, while decreasing the chemical fertilizer level.

Abstract

The environment is one important factor that must be considered in supporting sweet potato productivity. Environmental factors can be biotic and abiotic, including the availability of nutrients and microbes in the soil. This study aims to identify the nutrient content of the soil in wetland and upland, identify the total invertase microorganisms in wetland and dupland, and identify the relationship between soil nutrients and microorganisms during the growth of Cilembu sweet potato in dry and wetland agroecosystems. This research was conducted on upland and wetland in Cilembu Village, Sumedang Regency. The experimental design used was a single randomized block design (RBD) with six treatments and three replications:  A; Rancing, wetland, B; Biang wetland, C; Mencrang wetland, D; Rancing, uplands, E; Biang, uplands, F; Mencrang, upland. Parameters observed included pH, C-organic, total-N, available-P, exchangeable K, exchangeable Na, exchangeable Ca and exchangeable Mg, CEC, and total invertase-producing bacteria. The results showed that in wetland nutrient content such as N, P, exchangeable Ca,  Mg, Na, CEC, C-organic and pH tended to be more available. K content and abundance of invertase bacteria are more available in upland. The availability of invertase bacteria has a close relationship with the K content. The information generated in this study can be used as a basis for determining an effective location to produce good quality.

Abstract

Inceptisols have problem in phosphate availability. Soil P content is very low available to plants because it is bound by soil colloids. One of the efforts to increase the P nutrient in the soil in a sustainable way by using P-Solubilizers that can dissolve phosphate in the soil so that it is available for plants. The purpose of experiment was to determine the effect of the combination dose of kaolin based P-Solubilizer and P fertilizer for improving P availability, P uptake, phosphatase, and maize yield on Inceptisols. The kaolin-based P-Solubilizer was used a consortium of phosphate solubilizing microbes (PSM) consisting of Bacillus subtilis, Burkholderia cepacea, Pseudomonas mallei, and Trichoderma asperellum. This experiment was conducted in the experimental field of the Laboratory of Soil Chemistry and Plant Nutrition, Faculty of Agriculture, Universitas Padjadjaran, Jatinangor, from July to December 2021. The experiment used a randomized block design (RDB) method with nine treatments and three replications, with details of 0 P-Solubilizer + 0 P-fertilizer; 100% P-fertilizer; 100% P-solubilizer; and combination 50%, 75 %, 100%, and 150% P-solubilizer with 50%, 75%, and 100% P-fertilizer. P-solubilizer 100% recommended dose 50 kg ha-1 and P-fertilizer recommended dose 100 kg ha-1. The results showed that the dose of 100% P-Solubilizer (50 kg ha-1) + 75% P (75 kg ha-1) showed the best results in increased P-availability (346,93%), P-uptake (312,5%), Phosphate activity (33,5%), and maize yields (48,09%) compared to without application of P-solubilizer and P-fertilizer. This consortium isolate could be developed as a P-Solubilizer with the ability to increase the efficiency of P up to 25%.

Abstract

Lead pollution in rice fields in Rancaekek is attributed to the inadequate processing of waste from the textile industry. This phenomenon engenders a decline in soil fertility, thereby posing a threat to both food quality and agricultural sustainability. Employing N Bio-Organomineral fertilizer stands as one of the measures aimed at ameliorating the quality of rice fields afflicted by heavy metal contamination, particularly lead (Pb). This study seeks to elucidate the impact of N Bio-Organomineral fertilizer on various soil parameters, namely pH, NO3 - , soil organic carbon (C-organic), soil Pb solubility, and plant Pb uptake. The research was conducted in Linggar Village, Rancaekek, spanning from December 2019 to April 2020. Utilizing a Randomized Block Design as the experimental setup consisted of eight treatments with four replications, including: a control (0), urea at 250 kg/ha, and varying doses of the fertilizer at 250, 500, 750, 1000, 1250, and 1500 kg/ha. N Bio-Organomineral fertilizer represents a modified form of nitrogen fertilizer comprising urea, zeolite, activated charcoal, and compost enriched with Bacillus subtilis, formulated in a ratio of 60:20:10:10, respectively. The findings indicate that the application of N Bio-Organomineral fertilizer leads to an augmentation in soil NO3 - and C-organic content, while concurrently mitigating the uptake of Pb by plants. Among the treatments, the application of 500 kg/ha of N Bio-Organomineral fertilizer emerges as the most efficacious in enhancing soil NO3 - and C-organic content, as well as diminishing Pb accumulation in plants
