Abstract

This study aims to explore the root growth patterns of cucumber (Cucumis sativus L.) cultivated in a polybag system, and examine the implications for nutrient absorption efficiency and plant survival. The method used was a systematic literature review, with narrative analysis of recent studies in the last five years. Data were analyzed to identify the relationship between root architecture, growing medium, and nutrient absorption efficiency. The results showed that the polybag system, with its limited root growing space, promoted adaptation of root growth patterns, including an increase in lateral root density and a reduction in primary root length. Coconut fiber- and vermiculite-based growing media were shown to increase nutrient absorption capacity by up to 30%, while inoculation of rhizosphere microorganisms, such as mycorrhiza, increased phosphorus use efficiency by up to 25%. In addition, optimal root zone temperature plays an important role in supporting root metabolic activities. The conclusion of this study confirms that optimizing root growth patterns through growing media, temperature management, and utilization of microorganisms can significantly increase the productivity of cucumber plants. These findings provide a basis for developing more efficient and sustainable cultivation strategies in modern horticultural systems.

Abstract

This study examines the effectiveness of organic fertilizers in improving the quality and yield of cucumber (Cucumis sativus L.) plants through a comprehensive literature study. A systematic review was conducted on recent scientific publications that discuss various types of organic fertilizers, including chicken manure, bokashi, organic liquid fertilizer, and eco-enzyme. The research method used a literature study approach by analyzing articles from 2020-2024, focusing on the effectiveness of organic fertilizers in increasing the growth and productivity of cucumber plants.The results showed that organic fertilizers do not merely provide nutrients, but transform as agents of soil ecosystem regeneration. Each type of organic fertilizer has a unique mechanism in influencing plant growth, including increased microbiological activity, optimization of soil structure, and stimulation of the root system. Variations in plant responses depend on genotype, fertilizer composition and environmental conditions. The research resulted in practical recommendations for sustainable organic fertilization strategies, emphasizing the importance of a precision and holistic approach in cucumber crop nutrient management. The findings make a significant contribution in the development of sustainable agriculture.

Abstract

The use of liquid organic fertilizer (POC) is an innovative solution to increase crop productivity in drylands that face challenges in soil fertility and water availability. This study aims to evaluate the effect of various types of POC, including moringa, kirinyu, rabbit urine, fermented fruit waste, and local microorganism-based (MOL) POC, on plant growth and yield. The method used was literature review and analysis of literature from various journals, theses, theses, and dissertations, which were analyzed descriptively and quantitatively. The results showed that all types of POC increased plant productivity with an average increase of 20-40% compared to the control, with rabbit urine recording the highest increase of 40%. The effectiveness of POC comes from the content of nutrients, bioactive compounds, and microorganisms that improve soil structure, increase water retention, and spur nutrient absorption. The discussion underscored the importance of utilizing local resources to reduce environmental pollution and improve agricultural sustainability. In conclusion, POC proved to be an effective alternative to increase crop yields in drylands while supporting sustainable agriculture. Recommendations for further research include further exploration of local organic materials and application of POC on a field scale.

Abstract

This research aims to explore the role of soil microorganisms in improving soil fertility and agricultural productivity to support sustainable agriculture. Using the literature review method, various scientific literatures were analyzed to identify the potential, challenges, and optimization strategies of microorganism technology. Microorganisms such as Nitrobacter, Streptomyces sp. and Trichoderma sp. play significant roles in nitrogen cycling, organic matter decomposition and plant pathogen control. In addition to naturally improving soil nutrition, these microorganisms also support agricultural efficiency by reducing dependence on synthetic chemical fertilizers and pesticides. However, the adoption of this technology faces obstacles, such as farmers' lack of knowledge and limited access to quality products. Therefore, strategic steps are needed in the form of training programs, extension, and policy development to support the implementation of microorganism-based technologies. In the context of climate change, microorganisms also contribute to greenhouse gas mitigation and increase crop tolerance to abiotic stress. The results of this study emphasize the importance of microorganisms as a sustainable solution to the challenges of modern agriculture, as well as the need for collaboration between various parties to increase the capacity of farmers in implementing this technology.

Abstract

Agricultural waste treatment is an organism that offers innovative solutions to reduce the negative environmental impact of waste while increasing agricultural productivity. By using microorganisms such as bacteria, fungi, and actinomycetes, wastes such as straw, manure, and coffee grounds can be effectively treated. This biological process accelerates the decomposition of organic matter into more benign substances and nutrients, such as nitrogen, phosphorus and potassium, which are essential for plant growth. In addition to improving soil fertility, the use of organic fertilizers also reduces dependence on chemical fertilizers, greenhouse gas emissions, and sustainable agriculture. The aim of this study was to investigate the role of microbiology in agricultural waste transformation by examining its mechanisms, potentials, and challenges. The results of this study show that microorganism-based technologies contribute to more environmentally friendly practices and reinforce fundamental economic principles. Processing agricultural waste into organic fertilizer is a strategic step in realizing sector sustainability.

Abstract

Microorganisms are highly beneficial in sustainable agriculture as they are key components of the soil ecosystem and participate in various processes that enhance soil fertility, improve crop quality, and reduce reliance on synthetic chemicals. This study employs a meta-analysis or literature review method to examine previous research on the role of microorganisms in agriculture, specifically on how microorganisms play a critical role in sustainable farming. Most available studies rely on qualitative data or case studies, limiting the ability to conduct more in-depth quantitative analysis. The results indicate that waste processing into organic compost fertilizer is crucial. Applying organic farming methods improves crop quality while maintaining ecosystem balance.

Abstract

The use of fertilizer in plant cultivation is basically carried out to meet the availability of nutrients for plants in order to obtain optimal results. However, excessive use of fertilizer can actually have a negative impact on the ecosystem, such as environmental pollution and decreasing soil quality. The use of biofertilizer as a substitute for biological fertilizer is an alternative that can be used to reduce dependence on chemical fertilizers. Biofertilizer is a biological fertilizer containing various live microorganisms which is used to increase plant productivity by improving the quality of soil fertility. One of the microbes that acts as a biofertilizer is the Bacillus sp. The purpose of this article is to find out how Bacillus sp. functions as a biological fertilizer that can increase soil fertility and increase crop productivity. Bacillus is a genus of bacteria that can be used as a biofertilizer because of its more varied antagonistic mechanisms and ability to produce endospores. The method used in this article is a meta-analysis or literature review method in several journals published online which are integrated with Google Scholar.
