Abstract

Husk through composting techniques. However, information about the characteristics of soybean husk still needed to be studied more deeply. This caused coagulation of primary metabolites which had a very important biological functions as an energy source, fuel and intermediates for planting, the formation of RNA and DNA structural work (ribonucleic acid and deoxyribonucleic acid), this could be used to help explore the profile carried out in soybean husk degradation. Detection of carbohydrate compounds in this study used Gas Chromatography–Mass Spectroscopy (GC–MS) because it was a powerful tool in characterizing compost. The purpose of this study was to detect carbohydrate compounds in compost made from soybean husk and cow manure. Thus, further information obtained could be used as recommendations in handling soybean husk, especially as organic fertilizer through composting techniques.The study was conducted using a Randomized Complete Block Design (RCBD) with 5 composting arrangements with five replications. Related to payments were: C1: soybean husk (100 %), C2: cow manure (100 %), C3: soybean husk: cow manure (50 %: 50 %), C4: soybean husk: cow manure (75 %: 25 %) and C5: soybean husk: cow manure (25 %: 75 %). Data were analyzed using GC–MS and Least Significant Difference (LSD). Based on analysis using GC–\MS on compost, six sugar compounds were detected. While the treatment that showed the highest area of the curve was C5 (25 % soybean husk: 75 % cow manure), this result was directly proportional to the Least Significant Difference (LSD).

Abstract

Strawberry production in Indonesia has been on the rise in various regions, including Aceh, Riau, Jambi, DKI Jakarta, West Java, Central Java, East Java, and others. According to the Central Bureau of Statistics (2021), production fluctuated from 573.00 tons in 2019 to 559.00 tons in 2020, rebounding to 838.00 tons in 2021. Factors influencing production include land availability, proper fertilization methods, and planting media. Adequate fertilization, considering both dosage and frequency, plays a crucial role. The study, conducted at Balitjestro GreenHouse in Batu City, East Java, focused on the interaction between lime and fertilizer on strawberry plant growth and yield. Synthetic fertilizers, particularly phosphate fertilizers, are essential for plant growth. The research utilized a completely randomized design with two factors: CaCl2 lime (S) and phosphoric acid fertilizer (R), resulting in two treatment combinations (4x4). Each treatment, repeated three times, yielded 48 experimental units, with one plant per unit. Results indicated that the addition of CaCl2 lime and phosphoric acid fertilizer had a minimal impact on strawberry plant growth and production. Specific combinations, such as calcium chloride and phosphoric acid fertilizer with KCL 7.2 grams and urea 12.5 grams, did not significantly affect vegetative growth parameters like plant height and leaf count. However, these combinations did influence strawberry plant production. The study underscores the need for careful nutrient management to optimize strawberry production in Indonesia.

Abstract

The study aimed to determine the effectiveness of organic and inorganic fertilization and to obtain the right dose of organic and inorganic fertilizers for the growth and production of seed cotton plants. The research was designed using a Randomized Group Design with 8 treatments repeated 5 times. The treatments were inorganic fertilizer Balittas package dose (100 kg N + 37.5 kg P2O5 + 37.5 kg K2O), Balittas package dose treatment with the addition of cottonseed cake bokashi, Balittas package dose with the addition of cow manure, Balittas package dose with the addition of cottonseed cake bokashi and cow manure and treatment with a dose of ½ Balittas package with the addition of organic fertilizers mentioned above, and treatment only with the use of organic fertilizers. The results showed that the treatment of organic and inorganic fertilizers was very effective in increasing the growth and production of cotton plants. The fertilization dose of Balittas package (100 kg N + 37.5 kg P2O5 + 37.5 kg K2O) + cottonseed cake bokashi + cow pukan gave better growth and production compared to other treatments, but the fertilization treatment of ½ dose of Balittas package (50 kg N + 18.75 kg P2O5 + 18.75 kg K2O) + cottonseed cake bokashi tended to be more efficient.

Abstract

The increasing demand for tomatoes has prompted concerns about the potential decrease in tomato supply, as reflected in rising market prices. To address this issue, efforts should be directed towards enhancing the productivity of tomato plants. This study focuses on identifying the interactive effects of fertilizer type and tomato variety on tomato plant development.Utilizing a Completely Randomized Design (CRD) with two factors, the first factor involves three types of fertilizers (Goat Manure, NPK, and Liquid Organic), while the second factor includes four tomato varieties (Permata, Donna, Serfo F1, and Tinatoon F1). Various parameters, such as plant height, number of leaves, number of branches, stem diameter, number of fruits, and fruit weight, were monitored.The study's results highlight a significant interaction between fertilizer types and tomato varieties, with the NPK fertilizer treatment and the Tinatoon F1 variety demonstrating optimal height among the tomato plants. Notably, NPK fertilizer exhibited a positive influence on tomato plant development, particularly in plant height at weeks 7, 10, and 13, as well as in the number of leaves, number of branches, fruit weight, and stem diameter. In contrast, the type of tomato plant did not significantly impact tomato growth, except for the Tinatoon Variety, which consistently outperformed others in terms of branches, leaves, stem diameter, and fruit weight during the observation period at weeks 7, 10, and 13. These findings underscore the importance of fertilizer selection, specifically favoring NPK, in optimizing tomato plant productivity.

Abstract

Rice (Oryza sativa L.) is one of the most important food commodities for human nutritional needs. The amount of rice consumption per capita per week in 2017 was 1,571 (BPS, 2018). Population growth over time has resulted in increased demand for rice in Indonesia. Therefore, the demand for rice by the Indonesian people is very high. The problem is that the demand for local rice in Indonesia is still low, so one way to meet the demand for rice in Indonesia is through imports. Utilization of water and land resources is one of the common challenges faced in realizing national food security (Fita et al., 2013). Low productivity of rice plants is generally caused by biological, physical, and chemical soil problems. One of the efforts to increase the productivity of rice plants is by utilizing biological resources such as biofertilizers.The objectives of this study were to determine the appropriate dose of biofertilizer that will affect the growth of rice plants, determine the combination of biofertilizer and application interval that affects the growth of rice plants, and determine the effect of biofertilizer application on 2 varieties of rice plants (Ciherang and IR 64). The design used in this study was a factorial complete randomized block design (RKLT) to determine the interaction and effect of each factor. Then DMRT (Duncan's test) was conducted to determine the best treatment. Based on the results of the study, it was found that the interaction between biofertilizer treatment and rice varieties had significant effects on almost all observed variables except stem diameter at 70 HST, number of clumps at 42 HST, number of productive tillers, and weight of planted seeds. The combination of biofertilizer treatment and rice variety had inconsistent effects on growth parameters and rice yield.

Abstract

The study investigates the nutritional composition of soybeans, emphasizing their richness in calcium, iron, zinc, phosphorus, magnesium, thiamine, riboflavin, niacin, and folic acid. Soybeans are highlighted as a significant source of essential amino acids, proteins, and vegetable oils, with dried soybeans comprising 34% protein, 19% oil, 34% carbohydrates (including 17% dietary fiber), and 5% minerals. The environmental conditions crucial for soybean cultivation are discussed, underscoring the need for a balance between air temperature and humidity influenced by rainfall. Optimal conditions, characterized by high air temperatures and low humidity, are essential for quality soybean production. Despite increasing domestic demand, Indonesia imports soybeans to meet its needs. To address this issue, the study proposes a solution involving the application of rhizobacteria to enhance soybean productivity. The research aims to assess the impact of various bacterial isolates on the productivity of Dega1 and Anjasmara soybean varieties, exploring potential interactions between rhizobacterial isolates and soybean varieties. Employing a factorial RAK Split Plot experimental design with two factors (variety and treatment) and three repetitions, the study reveals that rhizobacteria-treated soybean plants exhibit increased productivity, with more leaves and greater height compared to the control. The abundance of leaves contributes to additional branches and flowers, ultimately enhancing pod development on soybean plants.

Abstract

The study conducted at the Integrated Laboratory of the Faculty of Agriculture and Animal Husbandry, University of Muhammadiyah Malang, aimed to formulate granule and liquid biofertilizers for corn cultivation on dry land in Indonesia, covering 144.47 million hectares. Corn is a crucial agricultural commodity in the country, aligning with the Sustainable Food Self-Sufficiency Policy program. Fertilizers, especially biological ones with plant growth-promoting rhizobacteria (PGPR), play a pivotal role in enhancing both the quality and quantity of corn production. The research utilized a Nested Split Plot Design, considering varying levels of drought stress (100%, 70%, and 40% of field capacity) and bacterial density (control, 10^9, 10^8, and 10^7). Results indicated no significant interaction between granular and liquid fertilizer densities across different field capacities. While the PGPR consortium in both fertilizer types showed limited effectiveness in boosting maize growth and yield, the highest average performance was observed at a density of 10^7. Additionally, certain stress levels did not contribute to increased maize growth and yield, except for the 100% field capacity treatment. It was noted that extreme temperatures, reaching up to 54°C in the plastic house, might have hindered the expected interaction. Plant growth tends to decrease drastically below 15°C or above 40°C, as these temperatures activate physical and chemical processes in plants. The study underscores the importance of considering environmental factors in optimizing biofertilizer effectiveness for sustainable corn cultivation on Indonesian dry land.

Abstract

Banana production in Indonesia has decreased due to the lack of availability of healthy seeds. The purpose of this study was to determine the effect of BAP on the multiplication of two banana varieties (Kepok Manurun and Kepok Unti Sayang) by in vitro culture. This study used a completely randomized design (CDR) in a factorial manner with 2 factors. The first factor was the banana variety (Kepok Manurun and Kepok Unti Sayang), the second factor was the concentration of BAP ZPT (0, 1, 2, 3) with 4 replications where each replication consisted of 4 samples, each bottle was planted with 1 plantlet for a total of 128 bottles. The results showed that the concentration of BAP did not effect the multiplication of two kepok banana varieties in vitro. The BAP concentration of 2 ml/l produced the highest number of shoots of 1,91 shoots, the concentration of BAP of 1 ml/l produced the highest number of leaves of 1,52 leaf, while the concentration of BAP 0 ml/l or without BAP result in the highest plant height of 1,05 cm. While the highest number of roots was found in the BAP treatment of 1 ml/l, the number of root tips, the highest root length was found in the BAP treatment 0 ml/l, while the concentration of BAP 2 ml/l produced the highest number of tillers of 1,39 tillers, and the concentration BAP 1 ml/l resulted in a stem diameter of 3,98 cm.

Abstract

The study conducted in Cikajang District, Garut Regency from February 20 to June 15, 2023, aimed to assess the impact of different compositions of organic mulch, derived from water hyacinth and banana stems, combined with a blend of chicken and cow manure on lettuce growth and yield. Employing ANOVA analysis at a 5% significance level, with a DMRT follow-up test, the research involved seven treatments and two controls. The treatments included organic mulch without manure mixture (M1), and organic mulch with 5% (M2), 10% (M3), 15% (M4), 20% (M5), 25% (M6), and 30% (M7) cow and chicken manure. Positive control was Black Silver Plastic Mulch, and negative control was without mulch. The study revealed significant effects of organic mulch treatments on plant height, leaf count, and crop diameter during the initial vegetative growth stage. Specifically, treatment M5, comprising organic mulch from water hyacinth with a 20% mixture of cow and chicken manure, demonstrated a notable increase in net head weight per plot at harvest. This suggests the potential of this particular mulch composition for enhancing lettuce yield. The findings emphasize the practical application of organic mulch, particularly M5, as a beneficial strategy in lettuce cultivation, promoting growth and ultimately increasing harvest yield.
