Edukasi Kesehatan Tanah pada Kelompok Tani melalui Pembuatan Plant Growth Promoting Rhizobacteria (PGPR)

Currently, inorganic fertilizers are still farmers' choice because they are considered more practical and quickly affect plant growth. However, using inorganic fertilizers in the long term will undoubtedly affect the health and quality of the soil. On the other hand, farmers are generally used to using inorganic inputs, causing dependence on chemical products, further increasing the decline in soil quality. A healthy level of soil quality needs to be maintained so that agricultural products can always be maintained and safe for human consumption. This community service activity aims to provide soil health education and farmers' knowledge of Plant Growth Promoting Rhizobacteria (PGPR) as a solution for maintaining soil quality and reducing the use of inorganic fertilizers. The activity results show that farmers are strongly motivated to maintain the quality and health of their soil. The PGPR product is still considered a new product that has never been implemented by the Mulyo farmer group in Gumukmas Village. Farmer group members have high enthusiasm for the PGPR products they make. The PGPR products made are expected to be able to increase production and reduce the effects of the use of inorganic fertilizers. Periodic assistance and application evaluation in the field needs to be carried out so that farmers understand the proper application technique.

ABSTRACT Spinach plant production has decreased every year and the use of inorganic fertilizers is still often used by farmers. The right innovation of Brazilian spinach cultivation technique is by using biological fertilizers. This study used a non-factorial completely randomized design (CRD) with 5 treatment levels repeated 4 times, namely C0: 0 mg/plant (Control), C1: 20 mg/plant, C2: 40 mg/plant, C3: 60 mg /plant, and C4: 80 mg/plant so that there are 20 experimental treatment units. The variables used in this study were plant height, number of leaves, number of branches, leaf area, chlorophyll content, canopy area, and plant fresh weight. The data obtained were analyzed for variance (ANOVA) and further tested with Duncan's Multiple Range Test (DMRT) with a confidence level of 95%. The results showed that there was a significant effect of the application of biological fertilizers on the growth and yield of Brazilian spinach (Althernanthera sisso), namely height plants that produce the highest average value of 24.23 cm, the variable number of branches with the highest value is 6.25 branches, the variable leaf area with the highest value is 131.88 cm2, and the variable number of leaves that gives a very significant different effect with the highest value ie 11.25 strands. The correct dosage of biological fertilizers is found in the Agrice Plus fertilizer treatment with a dose of 80 mg/plant for all observed variables. Keywords:, Brazilian Spinach, Biofertilizer

Application of Various Biofertilizers on Vegetative Growth in Oil Palm Seedling

Continuous application of inorganic fertilizers has negative effects on the environment such as plants and soil. One of the efforts to reduce the use of inorganic fertilizers is the use of microbes as biological agents. This study aims to examine the effect of biofertilizer applications from brands A, B, C, and D on vegetative growth in oil palm seedling. This research was held at Bogor Agricultural Development Polytechnic. The study was arranged in a completely randomized design (CRD) followed by Duncan's test. The treatments consisted of 4 brands of biofertilizer with 3 doses (10, 20, and 30 mL/L water) and 8 replicates. The results showed that brand A had a significant effect on dry weight at a dose of 20 mL/L water with a dry weight value of 10.43 gram/plant. The highest root length significantly was the application of brand C at a dose of 20 mL/L of water, which was 39.06 cm/plant. However, the highest root volume significantly was fertilizer brand A with a dose of 10 mL/L of water, which was 12 cm3/plant.

Fertilizer Optimization through Machine Learning-driven Models: An Empirical Investigation on Smart Farming of Amaranth

Amaranth is a highly nutritious leafy vegetable cum pseudo-cereal crop known for its adaptability to various climatic conditions, making it a promising crop for addressing the food security and nutritional needs of a growing population. To enhance its quality and boost yields, farmers mainly depend on synthetic fertilizers. However, the excessive use of inorganic fertilizers to maximize crop yields poses significant ecological risks. This study aimed to investigate the impact of excessive inorganic fertilizer on the growth, yield, and physiological attributes of Amaranthus with the aid of advanced machine learning paradigm. An experimental pot trial was conducted using different NPK fertilizer dosage regimes, and agronomic parameters such as moisture level, crop yield, plant height, leaf length, leaf width etc. were measured and analyzed using statistical methods. The results demonstrated that the application of excessive inorganic fertilizer initially promoted plant growth but surpassed optimal levels resulting in negative effects, including stunted growth and reduced vigor. By identifying the Amaranthus's productivity and adaptability in different chemically treated soil conditions and automatically phenotyping its traits using image-based machine learning models, this study aims to determine the overuse of synthetic fertilizers. A comparative evaluation of different learning algorithms was carried out and the experimental result proves that SVM classifier could be a more appropriate learning algorithm for the proposed system with 80% accuracy. These findings highlight the importance of adopting sustainable fertilizer practices for the cultivation of Amaranthus and emphasize the need for ecological balance in crop production systems.

Effect of fertilization on the accumulation and health risk for heavy metals in native Andean potatoes in the highlands of Perú

Soil infertility is a global problem, amendments such as organic fertilizers and mineral fertilizers are used to improve crop yields. However, these fertilizers contain heavy metals as well as essential mineral elements. The objective of the study was to determine the effect of organic and inorganic fertilizer on the accumulation and health risk of heavy metals in tubers. The plants were cultivated at an altitude of 3970 m using four treatments (poultry manure, alpaca manure, island guano and inorganic fertilizer) and a control group. Soil contamination levels and the degree of metal accumulation in the tubers were also determined. As a result, it was found that the use of inorganic fertilizer and poultry manure increased the values of Cu and Zn in soils, exceeding the recommended standards. The accumulation of heavy metals in potato tubers did not exceed the maximum recommended limits with the exception of Pb, which exceeded the limit allowed by the FAO/WHO (0.1 mg kg−1). Poultry manure contributed to the highest accumulation of Zn, Cu and Pb in tubers with 11.62±1.30, 3.48±0.20 and 0.12 ±0.02 mg kg-1 respectively. The transfer of metals from the soil to the tubers was less than 1. Individual and total non-carcinogenic risk values were less than 1, indicating a safe level of consumption for children and adults. The cancer risk was found to be within an acceptable range. However, poultry manure and inorganic fertilizer treatments had the highest total cancer risk values in both age groups, suggesting a long-term carcinogenic risk.

Effect of Intercropping with Cowpea and Maize with Organic Manure Application on the Physiological Parameters

Intercropping involves cultivating two or more crops simultaneously in the same field, optimizing the use of land, water, light, and nutrients for higher yields compared to sole cropping. Organic manures, such as farmyard manure, poultry manure, oilseed cake, vermicompost, and bio-slurry, play a vital role in enhancing soil health by providing essential nutrients and supporting microbial populations. In contrast, excessive use of inorganic fertilizers can lead to environmental degradation. Present study explores the synergistic effects of intercropping and organic manure application on the physiological parameters of maize (Zea mays) and cowpea (Vigna unguiculata). Agricultural practices like intercropping optimize resource utilization and enhance overall productivity, especially in regions with limited water resources like Mizoram, India. These practices exhibit positive responds when combined with organic manure on soil health and yield attributes on crops. The experiment was laid out in randomized block design (RBD) with ten treatments replicated thrice. The result indicate that plants treated with Maize + Cowpea (2:1) + 50% of RDN (Recommended doses of Nitrogen) through Farm Yard Manure + 50% of RDN through Poultry Manure + Lime (200 kg ha-1), resulted in significantly maximum physiological parameters of the crops.

Field trial was designed on Randomized Block Design with three replications and ten treatments. Seedling were raised in polybag and 45 days old seedling were transplanted to the main field. Manure and fertilizer were applied as per treatment in ten equal split doses at 30,60 and 90days intervals. The treatment T9 (RDF) FYM+ Panchgavya (90ml/l) registered significantly maximum vegetative growth, chlorophyll content and survivality %. On the basis of our experimental findings, it can be concluded that the best result was found in treatment T9 (RDF) FYM+ Panchgavya (90ml/l) in term of vegetative growth parameters viz., plant height (cm), Number of leaves per plant, stem diameter (mm), leaf area (cm2) and root to shoot ratio, leaf area index (LAI), chlorophyll content and survivality % of papaya (Carica papaya L.) cv. Red lady.

Moving towards a mechanistic understanding of biostimulant impacts on soil properties and processes: a semi-systematic review

Biostimulants are gaining prominence in scientific research, with the potential to enhance plant productivity through benefits to crop yield/quality and tolerance to environmental stresses. Through possible improvements to nutrient use efficiency, they may also lessen the adverse environmental impacts of conventional inorganic fertilizer use in agriculture. The application of biostimulants is currently uncommon as a farming practice, with uncertain effectiveness in delivering these potential benefits. Current research focuses on biostimulant effects on plant physiological changes. There is little scientific evidence on the impact of biostimulants on soil properties (biological, physical, or chemical) or soil functions. This knowledge gap should be addressed considering the vital role of soil processes in the bioavailability of nutrients, as reflected in crop productivity. This review evaluates laboratory and field experimental work on the effectiveness of common, non-microbial biostimulants, with a focus on their modes of action within the soil matrix. Of 2,097 initial articles returned through the search strings, 10 were within the scope of this review. A common soil biostimulant mechanism emerges from this literature. This relates to the supply of nutrients provided by the biostimulants, which stimulate native soil microbiology in mineralizing organic material in the soil, thus producing more bioavailable nutrients for plant uptake. Additionally, some articles link biostimulant effects to soil physical and chemical changes, which in turn impact soil biology (and vice versa). However, there is inconsistent evidence to provide full support for these explanatory mechanisms. This review highlights the need for further research into the effect of biostimulants on the native soil microbiology and associated soil properties, to provide greater clarity on biostimulants’ modes of action and greater mechanistic insights into how they can be used to improve crop production.

Improving marketable yield and phytochemical characteristics of N-fertilized tomato fruits with soil organic amendments through Azolla

ABSTRACT There is a growing demand for organic vegetable products. Increasing the marketable yield and quality of tomatoes through the use of optimal organic and inorganic fertilizers is a critical agronomic measure for crop productivity and soil health. However, little is known about the effects of Azolla on tomato productivity, fruit quality and soil organic changes. The aim of this study was to compare the effects of organic and inorganic fertilization on marketable yield and quality characteristics of tomato fruits. A pot experiment was conducted with four concentrations of Azolla and nitrogen in a completely randomized design. The results showed that Azolla has the potential to replace nitrogen and has a significant impact on fruit quality. The interactions of Azolla and nitrogen on the number of clusters per plant, the number of flowers per cluster, the proportion of fruit set, the number of fruits per cluster and the marketable fruit yield were significant. It can be concluded that the combination of Azolla and inorganic nitrogen fertilizer linearly increased the marketable yield and quality of tomato fruits.

The present investigation was undertaken to validate the integrated use of inorganic fertilizers and biofertilizers inoculated in organic manures on the physiological attributes and of pearl millet in the School of Agricultural Science, Karunya Institute of Technology and Sciences, Coimbatore, India. The experiment was laid out in Randomized Block Design (RBD) with three replications, during the rabi season of 2023-24. Results outlined that the integrated nutrient management practice of applying Azospirillum & PSB enriched vermicompost @ 6 t ha-1 + 100% Recommended dose of N, P2O5 & K2O has significantly increased the physiological attributes (leaf area index, crop growth rate, chlorophyll index), and yield (grain yield and stover yield) of pearl millet. This was statistically on par with the treatment Azospirillum & PSB enriched FYM @12.5 t ha-1 + 100% RDF dose of N, P2O5 & K2O.

Optimizing agricultural management in China for soil greenhouse gas emissions and yield balance: A regional heterogeneity perspective

Balancing soil greenhouse gas emissions (SGE) with crop production is crucial for sustainable agriculture in China. Optimizing field management practices regionally can effectively promote carbon reduction and food security, given the varying SGE responses across agroecological regions. This study employed meta-analysis and machine learning techniques to assess SGE responses to nine different farming practices in seven distinct agroecological regions. It aimed to identify optimal management strategies for balancing SGE and crop production within each region. Findings underscore substantial spatial heterogeneity in the effects of management practices on SGE, with the combined use of organic and inorganic fertilizers (MOF-MF) demonstrating the most pronounced variability (standard deviation, SD = 1.80), where MOF resulted in SGE 610% of that with MF in the Southern China (SC) region, yet only 54% in Northwestern China (NWC). Conversely, straw incorporation exhibited the most minor variability (SD = 0.27), influencing SGE by 35%–62%. Additionally, the study reveals that soil and climatic conditions significantly modulate SGE responses. In scenarios characterized by humid and warm climates with soil pH ranging from 5.5 to 8.5 or initial SOC ≤10, the environmental impact on SGE was marginal. However, in highly acidic or alkaline soils or with initial SOC >10, SGE responses varied markedly with management practices in arid and cold conditions. The study further proposes agricultural management strategies to achieve the lowest SGE while maximizing crop yield. It recommends specific methods for fertilizer applications, straw management, irrigation, and tillage practices meticulously tailored to the unique conditions of each agroecological region. This research offers essential insights for agricultural stakeholders regarding cultivation strategies and delivers theoretical guidance for enhancing agricultural management and land-use planning throughout China's heterogeneous landscapes.

Short-Term Response of Soil Organic Carbon Indices to Different Farming Strategies and Crop Rotation Systems in a Semiarid Warm Region

Several indices can be used to assess the impact of short-term conservation agriculture strategies on improving soil organic carbon (SOC). To find out how the SOC pools and the carbon lability influence the carbon management index (CMI) in response to different agricultural practices in a warm semiarid region, the carbon lability index (LI) and the carbon pool index (CPI) were measured under the interactive effect of different fertilizer applications and crop residue management (hereafter referred to as “farming strategies”) in combination with four crop rotation systems in Ahvaz, Khuzestan, Iran, over four growing seasons from 2018 to 2020. The farming strategies were as follows: (1) using the standard rate of inorganic fertilizer used in the region and removing crop residues from the soil (SIF_no-CR); (2) applying the standard rate of organic fertilizers used in the region and returning 30% of crop residues to the soil (SOF_30% CR); and (3) integrating the use of inorganic and organic fertilizers and returning 15% of crop residues to the soil (IOF_15% CR). The crop rotation systems were fallow-wheat (F-W), corn-wheat (C-W), sesame-wheat (S-W), and mung bean-wheat (B-W). No statistically significant difference was observed between the different farming strategies and rotation systems with respect to LI after two years of the experiment. The highest (1.26) and lowest (1.06) CPIs were observed for SOF_30% CR and SIF_no-CR, respectively. The magnitude of the CMI values followed the order SOF_30% CR (121) > IOF_15% CR (107) ≥ SIF_no-CR (106). B-W and F-W had the highest and lowest CPI with values of 1.29 and 1.01, respectively. No statistically significant difference was found for the different crop rotation systems. Given the low impact of the common farming practices in the region, e.g., SIF_no-CR and F-W, on CPI and CMI at 24 months, our results showed that farming strategies with manure application and crop residue management and summer wheat-based rotation systems appear to be more appropriate farming strategies to improve CMI in arable land.

Digital technology in maize nutrient management research in northern Nigeria amid COVID-19 pandemic

The COVID-19 pandemic has been a life threatening and spreads wildly with physical human contact. Physical distancing is recommended by health experts to prevent the spread; thus, agronomic research has to be designed in conformity to this preventive standard during the pandemic. Consequently, this study was designed to evaluate the reliability of using digital tools in nutrient management research amid the COVID-19 pandemic in northern Nigeria. Fifty extension agents (EAs) were selected across 15 LGAs of Kaduna and Kano states. The EAs were trained on how to generate fertilizer recommendation using an android mobile phone-based nutrient expert (NE), to measure farmers’ field sizes using UTM Area measure mobile phone app, and open data kit to record, submit and aggregate data during the exercise. Each EA covered 50 farms, where two nutrient management practices—one determined by the farmers: farmer fertilizer practice (FFP), and the other generated using the NE were evaluated. Results show that around 90% of the farmers have an average field size of 1.13 ha. All selected farmers used improved maize varieties for planting, among which 21% been able to use the exact recommended or lower seed rate. Use of inorganic fertilizer was 33% higher than the average recommended NE rate, while average yield of the NE fields was 48% higher than for the FFP. The results of this study indicate that yield can be improved with site-specific nutrient management (SSNM) extension approach. The SSNM using digital tools as the NE seem promising and befits to agronomic research in northern Nigeria amid the COVID-19 pandemic.

This study aims to evaluate how green manure applied with Chromolaena odorata and Gliricidia sepium leaves, along with NPK compound fertilizer (phonska), affects the growth and yield of sweet corn (Zea mays saccharata L.). Conducted in Telaga Kodok, Central Maluku, from September to November 2022, the experiment utilized factorial design with varying doses of green manure (0, 10, and 20 tons per hectare) and phonska fertilizer (0%, 50%, and 100% of the recommended dose). Observed parameters included plant height, leaf count, leaf area, leaf area index, cob length, cob weight with husk, cob weight without husk, and cob diameter. The results of the ANOVA analysis indicate that both factors and their interaction significantly influence sweet corn's growth and yield parameters. It is recommended to apply 20 tons of green manure per hectare and 100% phonska dose to achieve optimal results, considering parameters such as plant height, leaf count, leaf area, cob length, cob weight with and without husk, and cob diameter. By enhancing sweet corn productivity, supporting food security, and promoting sustainable agricultural sector growth, this research significantly contributes to optimizing the use of organic and inorganic fertilizers.

A Review on the Impact of Soil Acidification on Plant Nutrient Availability, Crop Productivity, and Management Options in the Ethiopian Highlands

Soil acidity is a type of soil deterioration that has a negative impact on Ethiopia's overall and Western Oromia's specific sustainable agricultural production. Currently, soil acidity in highland portions of Western Oromia, including Gimbi, Nedjo, and surrounding areas, is a major problem that can impede agricultural productivity. Reviewing the mechanisms of soil acidification, which can affect soil nutrient availability and agricultural production, as well as management choices, were done in this context for this review topic. The main causes of acid soils are leaching of exchangeable basic cations and topsoil erosion caused by high temperatures and heavy rains, which promote the loss of organic matter the most. In most of Ethiopia's highland regions, the removal of agricultural waste and ongoing use of inorganic fertilizers that produce acidity are major factors in the development of soil acidity. Al and Mn toxicity are caused by acid soil, which also reduces nutrient availability. Furthermore, agricultural yield decreases due to acidity in the soil. The management options for acid soils include crop types resistant to Al toxicity, liming, and the use of organic materials as integrated forms of soil fertility control. Therefore, lime and organic fertilizers should be employed as crucial agricultural techniques for small-holder farmers in acidic soil locations in order to decrease the effects of soil acidity.
