Abstract

Rhizoctonia solani Khun, is one of the fungi that causes important diseases in rice plants which can reduce rice production with a severity level of 6-52%. The aim of this research is to analyze the effectiveness of fungicide active ingredients in suppressing the development of R. solani disease. The research was carried out in March-July 2022. The method used was a Completely Randomized Design (CRD), in vitro testing was carried out with 10 treatments and 10 replications and in vivo testing was carried out in 9 treatments with 3 replications. Active fungicide treatments used: T1: Propinab 70%, T2: Trifloxystrobin 25% + Tebuconazole 50%, T3: Difenoconazole 250 g/l, T4: Azoxystrobin 200 g + Difenoconazole 125 g, T5: Difenoconazole 250 g, T6: Azoxystrobin 200 g + Difenoconazole 125 g/l, T7: Azoxystrobin 250 g/l + Difenoconazole 150 g/l, T8: Propiconazole 125% + Tricyclazole 400%, T9: Piraclostrobin 133 g/l + Epoxiconazole 50 g/l and T0= control without treatment. The parameters observed were calculating the mycelium diameter at 2 days after application (HSA) up to 14, calculating the percentage of attacks at 7 HSA1, 7 HSA2 and 14 HSA3. The results of the efficacy test showed that several fungicide active ingredients in controlling rice sheath blight (R. solani) in rice showed significant differences between treatments of fungicide active ingredients on the development of the pathogen. T2 active ingredient treatment: Trifloxystrobin 25% + Tebuconazole 50% provides the best efficacy test results in vitro and in vivo.

Abstract

The presence of weeds is a significant factor that contributes to the decline in maize yield. To reduce yield loss, appropriate weed control methods must be applied. The first step in determining these methods is to identify weed dominance and diversity. This study aims to identify the dominance and diversity of weeds in three corn planting systems: conventional, jajar legowo 1:2, and 1:3 spacing. The research was conducted at the Teaching Farm Polinela Organic Farm in Lampung Province from November to December 2023. Vegetation analysis was performed using a 0.5 m2 quadrant randomly placed on 10 plots of land. The dominance value of weeds was determined using the Summed Dominance Ratio (SDR) value, while the diversity of weeds was measured using the Shanon-Wiener index value (H'). The study found that the conventional field had 9 weed species, the 1:2 legowo field had 8 weed species, and the 1:3 legowo field had 5 weed species. Ageratum conyzoides was the dominant broadleaf weed species in both the conventional corn field and jajar legowo 1:2, while Asystasia gangetica dominated the jajar legowo 1:3 corn field. The weed diversity index analysis results for the three corn planting systems fall into the medium category. Specifically, the results are 2.12 for conventional corn fields, 1.94 for 1:2 jajar legowo corn fields, and 1.3 for 1:3 jajar legowo corn fields.

Abstract

Efforts to maintain rice production in the future face many challenges, including the availability of increasingly narrow land, attacks by plant pest organisms, and declining land fertility due to improper cultivation systems. More than 70% of rice fields are in a disturbed ecological status due to cultivation technology that could be more environmentally friendly, which can interfere with the sustainability of rice self-sufficiency. An environmentally friendly rice cultivation system needs to be developed. This study aims to measure the agronomic and physiological responses of 3 rice genotypes in sustainable cultivation systems. The experiment used a Group Random Design on 3 rice genotypes (black, red, and white) in both conventional and sustainable cultivation systems. The research was carried out in the experimental garden of Polinela Organic Farm, Lampung State Polytechnic, from September 2020 to September 2021. The results showed that the plant, leaf greenery, number of tillers, number of panicles, grain weight per panicle, and biomass weight were not significantly different between conventional and sustainable cultivation. At the same time, the harvest and production indices per hectare were significantly different. The physiological responses to the photosynthesis and transpiration rates differed markedly in conventional and continuous cultivation. In contrast, the conductance of stomata did not differ significantly in both cultivation systems. The red rice genotype is the best, and it has a broader adaptation to conventional and sustainable cultivation systems.

Abstract

The objectives of this study were to determine whether the application of kasgot organic fertilizer can increase the growth and yield of edamame, determine whether the effectiveness of kasgot organic fertilizer is better than non-kasgot organic fertilizer, and determine the best combination of kasgot organic fertilizer and non-kasgot organic fertilizer in increasing the growth and yield of soybeans. The treatments used: no organic fertilizer (control) (P0), non kasgot solid organic fertilizer (P1), non kasgot liquid organic fertilizer (P2), kasgot solid organic fertilizer (P3), kasgot liquid organic fertilizer (P4), non kasgot solid and liquid organic fertilizer (P5), kasgot solid and liquid organic fertilizer (P6), and non kasgot organic fertilizer and kasgot organic fertilizer (P7). The research findings indicate that the application of organic fertilizer enhances the growth and yield of soybeans compared to the control. Specifically, the combination of solid kasgot organic fertilizer (5 t ha-1) with liquid kasgot (50 ml L-1 water) produced the best plant growth and number of pods plant-1. It was also reported that the variables of number of branches, plant height, and plant wet weight significantly positively correlate with the number of pods plant-1.

Abstract

Organic farming practices have shown a potential to improve rice yields, aside from the popular conventional ones. This study aimed to comparatively analyze the morpho-physiological characteristics of rice plants grown under organic and inorganic farming. This research was conducted at the Polinela Organic Farm experimental station (5°21'10"S 105°13'43"E, 114 m sea above level), from February to April 2023 using a completely randomized design. The results showed that rice grown organically exhibited a notably higher chlorophyll index and actual water use efficiency compared to those grown inorganically. Conversely, inorganic farming resulted in a greater number of tillers than organic farming. However, there were no significant differences between the two systems regarding CO2 efficiency and plant height. An interesting fact is the improved water use efficiency by organic farming helps rice plants to achieve similar growth performance while requiring less water.

Abstract

Aquaponic is a plant cultivation technique that is widely used by farmers and today’s communities due to its efficiency and ability to increase the agricultural productivity. The aquaponic cultivation in general still uses simple systems, such as manually feeding the fish by spreading the feed at predetermined times, monitoring water pH using a pH meter and monitoring water height or level through measurements, requiring farmers to spend time and special labor to care for and maintain plants and fish. Therefore, a solution is needed in the form of a system that can monitor and control plants and fish conditions automatically and continuously for 24 hours. The system should have the ability to control and monitor feeding activities, water pH, water and environmental temperature, water level and environmental humidity. The system in question is the internet of things (IoT) system that can be used as a tool for automatic control and monitoring through an application. The IoT system consists of several sensors that are connected to a microcontroller which can measure water pH, temperature, water level and environmental humidity. The data obtained by the sensor will be sent to a server via Wi-Fi protocol and stored in a database. The system is equipped with a web application that can be accessed through a computer device. The application provides a visual display of data: time, water pH, temperature, water level and environmental humidity, making it easier for farmers to monitor aquaponic conditions from a distance without having to come to the land. Through the implementation of IoT in aquaponic cultivation, farmers can increase efficiency and agricultural productivity by reducing the time, labor and costs required for control and monitoring.

Abstract

Organic farming has been advocated as a more environmentally sound and ecologically balanced alternative to the dominant agricultural model. This study compared the decomposition of plant biomass in organically and non-organically managed soil properties. The treatments consisted of   non-organic land (A) and organic land (B). Non-organic land used chemical fertilizers as the main fertilizer, and organic fertilizers were not always given. In organic land, all fertilizers given were organic fertilizers, and organic pesticides have been carried out over the last five years. The area of ??each land studied was approximately 1,000 m2 divided into five points diagonally. Observations were made on soil pH, organic C, total N, and P Bray, as well as the amount and weight of soil macrofauna. The decomposition rate of the dried Edamame soybean biomass in the soil was estimated using the litterbag method. A litterbag measuring 30 x 20 cm with a pore size of 2-3 mm was used for this study. Seventy grams of plant biomass were put into the litterbag and buried in the soil to a depth of 10-20 cm. Analysis of C and N contents in plant biomass was carried out before and after incubation in the soil. The results showed that soil chemical properties are better, and soil macrofauna is more abundant in organic than non-organic land. Soil fertility in organic land was characterized by a larger decomposition rate constant (k) and a faster decrease in C/N ratios. The decomposition rate constant (k) in organic soil was 0.171, and that in non-organic soil was 0.105.

Abstract

Composting organic waste is significantly gaining attention as a sustainable and environmentally friendly material. This is because the use of microorganisms or microbial consortia in the composting process can enhance the quality of compost. Therefore, this study aimed to examine the impact of microbial consortia on cow manure composting efficiency and nutrient content. The experiment was conducted at the Polinela Organic Farm, Department of Food Crop Cultivation. A randomized block design was used with multiple treatments combining fresh cow manure and microbial inoculants, including catalyst, Bacillus, and Trichoderma. The parameters evaluated were the effects of water content, pH, temperature fluctuations, and macronutrient levels on composting, including nitrogen, phosphorus, and potassium. The results showed that microbial consortia significantly improved composting parameters such as moisture retention and temperature as a function of higher doses?of the inoculum. The highest total nitrogen (3.6%) and potassium (1.67%) content were obtained from Trichoderma treatment,?while the highest phosphorus (0.47%) content was obtained from Bacillus treatment. This?implied that microbial consortia could improve the quality and availability of composted nutrients in addition to the effectiveness of agricultural waste management and soil fertility practices. However, more research should be conducted?to determine the optimal microbial mixtures for various conditions of composting and the quality of the best compost produced.

Abstract

Optimal rice production is very important to meet national food needs amid a decline in harvest area and production yields. This study aims to analyze the influence of rice planting methods and genotype on the growth and yield of rice plants (Oryza sativa L.). The research was conducted on the Lampung State Polytechnic Experimental Land using a factorial Group Random Design (RAK) with two factors: the planting method (legowo row 2:1, planting distance 25x25 cm, and transplanter 2:1) and rice genotype (PTP 01, Inpari 24, Jeliteng, and Pandan Wangi) each method was repeated 3 times. The results of the study show that the interaction of planting methods and rice genotype has a significant effect on the growth and yield of rice plants. The combination of the 2:1 transplanter planting method and the Inpari 24 genotype gave the best results in terms of plant height (101.33 cm), number of saplings (29.33), number of productive saplings (25.00), and yield per hectare (12.48 tons/ha). The 2:1 transplanter planting method and the Inpari 24 genotype can be recommended as the best combination in increasing rice productivity.

Abstract

Soil fertility is a key factor in agricultural success; however, poor soil quality often hindersproductivity. One solution is the use of soil amendments to improve soil's physical, chemical,and biological properties. This study aims to analyze research trends on soil amendments inIndonesia based on agricultural journals from 2015 to 2024. Data were collected throughGoogle Scholar, with a total of 24 articles analyzed based on publication count, research design,indicator plants, treatments, and data analysis methods used. The analysis results indicatefluctuations in research trends, with the highest number of publications in 2021 and 2022. The Factorial Randomized Block Design was the most commonly used method, while the mostfrequently studied indicator plants were soybean, rice, and maize. The most common treatmentinvolved combining soil amendments with organic and inorganic fertilizers. The dominant dataanalysis method was ANOVA, followed by post hoc tests such as LSD and Tukey HSD todetermine significant differences between treatment groups. This study recommends furtherresearch on the effectiveness of soil amendments in supporting sustainable agriculture andexploring their use across various plant species and environmental conditions.
