Effect of nano titanium and organic fertilizer on broccoli growth, production, and biochemical profiles

Broccoli is considered a highly valuable vegetable due to its significant enrichment with health-promoting biochemicals. A greenhouse experiment was conducted to evaluate the responses of broccoli plants to different concentrations of titanium dioxide nanoparticles (TiO2NPs) applied via foliar spray and organic fertilizer (OF) applied to the soil. The results revealed that 40 mg/L TiO2NPs had the greatest effect on leaf dry matter (16.38%), total polyphenolic content (39.77 μg GAE/g FM), nitrogen (1.93%), and phosphorus content (0.35%) compared to the control and other treatments. OF applied at 30 L/ha improved the chlorophyll content (1.99 μg/g FM). Furthermore, vegetative and root growth, fruit characteristics, and potassium content were significantly influenced by the interaction of 20 mg/L TiO2NPs with 15 L/ha OF. The combination of 20 mg/L TiO2NPs with 30 L/ha OF resulted in the most significant increase in root diameter (8.77 mm), chlorophyll b (0.40 μg/g FM), carotenoid (0.50 μg/g FM), and total flavonoid content (4.56 μg QE/g FM) compared to control plants and single effect of TiO2NPs and OF. The combination of 40 mg/L TiO2NPs with 15 L/ha OF increased the number of roots (21.84), and 40 mg/L TiO2NPs with 30 L/ha OF significantly increased total soluble solids (7.85°Brix) and DPPH free radical scavenging activity (5.12 μg/g FM). This study established that TiO2NPs were more effective for enhancing broccoli plant growth when applied in combination with OF and can be recommended for use in sustainable agriculture, particularly at the interaction of 20 mg/L TiO2NPs with 15 and 30 L/ha OF.

The samples were dried, powdered, and analyzed in the laboratory. Nitrogen content was determined using the Kjeldahl method, which involved digestion, neutralization, distillation, and titration processes. The concentrations of phosphorus, potassium, calcium, and magnesium were analyzed using UV-Visible spectrophotometry. Appropriate standards were prepared for calibration, and the macronutrient concentrations were calculated based on established protocols. Results: The dry foliage of Sophora mollis demonstrated macronutrient concentrations of 3.9% nitrogen, 0.6% phosphorus, 4.2% potassium, 2.4% calcium, and 0.8% magnesium. These values closely aligned with the sufficient ranges required for plant growth. The results highlighted the nutrient-rich profile of Sophora mollis, indicating its potential as a sustainable organic fertilizer. Conclusion: The study concluded that the dry foliage of Sophora mollis is a promising source of essential macronutrients and can serve as an effective organic fertilizer. Its use in sustainable agricultural practices can improve soil fertility and support crop productivity, particularly in tropical and subtropical regions.

Effects of microbial organic fertilizer on glycoalkaloid content and yield of Solanum procumbens Lour.

Solanum procumbens Lour. is a traditional medicinal plant known for its rich glycoalkaloid content. This research aimed to determine the suitable types and application rates of microbial organic fertilizers to enhance yield and glycoalkaloid content in Solanum procumbens Lour. A two-factor experiment was conducted using a Split-Plot Design (SPD) with three replications. The main plots included four types of microbial organic fertilizers (HD301, HD302, Komix-BL2, and HCMK7), while the sub-plots involved three application rates (2, 4, and 6 tonnes/ha per crop). Various parameters were measured, including fresh and dry biomass per plant, fresh and dry yield per ha, glycoalkaloid content, and glycoalkaloid yield across two cropping cycles. The results indicated that applying HCMK7 at a rate of 6 tonnes/ha per crop produced the highest outcomes: in the initial crop, a fresh weight of 255.2 g and dry weight of 111.1 g per plant, fresh yield of 15.77 tonnes/ha, dry yield of 6.99 tonnes/ha, glycoalkaloid content of 0.70%, and glycoalkaloid yield of 48.97 kg/ha. In the ratoon crop, the same application rate yielded a fresh weight of 282.5 g and dry weight of 134.6 g/plant, fresh yield of 17.62 tonnes/ha, dry yield of 9.21 tonnes/ha, glycoalkaloid content of 0.76%, and glycoalkaloid yield of 70.39 kg/ha. The highest average glycoalkaloid content (0.73%) and total glycoalkaloid yield (119.36 kg/ha) across both crops were also recorded at this application rate.

Response to chemical and organic fertilization in date palm (Phoenix dactylifera L.) Mejhoul variety in Northwestern Mexico

This research was conducted to determine the effect of chemical, organic, and combined fertilization on the fruit yield of the Mejhoul date palm variety in Northwestern of Mexico. The variables measured were polar diameter, equatorial diameter of the fruit, roundness index, number of clusters, number of leaves per palm, number of leaves per cluster, fruits with separated skin, dried fruits and commercial yield. The design used was complete randomized blocks with five replicates, where each palm tree was the experimental unit. The results indicate that chemical fertilization 262N-138P2O5-540K2O alone or in combination with compost application (three or six tons per hectare) increases polar and equatorial diameter, promoting the oval growth of dates. Fruits with separated skin continue to occur regardless of the origin of the fertilizers. The number of fruits increases with chemical fertilization, but the total yield of dates remains consistent across the treatments evaluated. In conclusion, date palms respond favorably to the combination of chemical and organic fertilization, but date yields did not increase.

Fish Waste Compost - A Fertilizer for Organic Agriculture

Fish markets produce a large amount of fish waste such as fish head, gut, intestine, fines, bones and scales that are generally dumped in the river or land-filling areas causing great intuitive pollution to the environment. Such impulsively growing contamination can be mitigated and checked though waste management in the form of organic composting. This study investigates the potential of fish waste compost as a sustainable organic fertilizer by converting fish waste, including gut, head, skin, bones, and fins, into compost using sawdust, banana and jaggery as supplementary materials. The matured compost was then analyzed for nutrient content and maturity through physical, sensory, biological, and chemical tests. Results showed that the compost, reduced to 70% of its original volume, had significant nutrient content with a C:N ratio of 28.6:1, a pH of 6.80, and an electrical conductivity of 1.45 dS/m. Biological tests demonstrated high germination rates, indicating non-phytotoxicity. Fish waste containing 10.56, 2.12, 0.82 and 0.10 percents of C, N, P and K respectively can be converted into an effective organic fertilizer which can enhance soil fertility. This approach not only addresses waste management but also offers a viable solution for recycling fish waste into valuable agricultural resources.

Increasing the Growth and Production of Alfalfa by Supplementation with Various Types of Organic Fertilizers and Arbuscular Mycorrhizal Fungi

This study aimed to evaluate the effects of various organic fertilizers and arbuscular mycorrhizal fungi (AMF) on the growth and production of alfalfa plants in the tropics. This study used a completely randomized design (CRD) factorial pattern consisting of two factors with ten replications. Factor A included the types of organic fertilizer, including chicken manure, cow manure, goat manure, and vermicompost. Factor B was the dose of AMF, which included 0 g and 10 g. The results revealed an interaction effect (p<0,01) between the type of organic fertilizer and AMF factors on AMF colonization in alfalfa roots and leaf chlorophyll. The single factor of the type of organic fertilizer had a very significant effect (p<0,01) on increasing the pH, plant height, number of branches, number of leaves, root fresh weight, shoot fresh weight, and shoot dry weight of the media. Moreover, the single factor AMF had no significant effect (p>0,05) on the observed parameters. In conclusion, the application of various types of organic fertilizers with 20% media volume effectively increased the growth and production of alfalfa plants, and the type of organic fertilizer, cow manure, was the best treatment. The application of organic fertilizers alone or in combination with 10 g of AMF did not significantly affect the growth and production of alfalfa plants

Analysis Of The Effect Of Organic Fertiliser Use On Plant And Soil Quality

Modern agriculture faces a major challenge in maintaining high productivity while preserving the environment. In recent decades, the use of synthetic chemical fertilisers has become a common practice worldwide to increase crop yields (Sari, 2023). This research aims at analysing the effect of organic fertiliser use on plant and soil quality. This research uses a quantitative method with a field experimental approach. This approach was chosen because it allows researchers to directly measure the effect of organic fertiliser use on soil quality and plants under environmental conditions. From the results in table 3 regarding the effect of granular and bulk organic fertilisers on plant growth, it shows that the NPK treatment alone produces the highest plant height (33.6 cm) with a production of 17.7 t/ha. In Table 4 regarding the effect of fertiliser treatment on dry weight and stem varieties, the combination of NPK with NPK + 2 t POG organic fertiliser gave a dry weight of grain of 19.5 kg and a dry weight of straw of 21.5 kg. From the results shown in Table 3, it can be seen that the use of bulk (PO bulk) and granular (POG) organic fertiliser has a positive effect on plant growth compared to the control. In Table 4, the combination of NPK with 2 tonnes of straw or granulated organic fertiliser (POG) resulted in an increase in grain dry weight, especially in the NPK + 2 t POG treatment, which reached 19.5 kg dry weight. From the results of this study, it is clear that the use of organic fertilisers significantly improves soil fertility and crop yields, especially when combined with chemical fertilisers such as NPK. Organic fertilisers not only improve soil physical and biological properties, but also increase the effectiveness of chemical fertilisers.

The experiment was laid down in RBD which consisted 9 treatment combinations viz; T1-Control (100%) (125:100:50), T2-100% N through FYM (25t/ha), T3-100% N through vermicompost (5t/ha), T4-100% N through poultry manure (5t/ha), T5-100% N through neem cake (2t/ha), T6-50% NPK + 50% N through FYM, T7-50% NPK + 50% N through vermicompost, T8-50% NPK + 50% N through poultry manure, T9-50% NPK + 50% N through neem cake and treatments were replicated three times. The treatment (T7) significantly affected various vegetative growth, yield and quality parameters. Results further indicated that the highest (3.27) benefit: cost ratio was observed in treatment (T7). Whereas, the lowest benefit: cost ratio (1.51) was recorded under control.

The effect of dosage of vermicompost and biourine plus on growth and yield of organic shallot (Allium ascalonicum L.)

Shallot is a common horticultural crop, providing a number of benefits. Effect of organic manure and liquid organic fertilizer and their interaction on growth and yield of shallot was studied. The purpose of this study was to determine the effectiveness increase organic shallot yield with dose fertilizer vermicompost and biourine plus. A two factor experiment with three replications, arranged in factorial randomized block design, was carried out. First factor was dose of vermicompost i.e without vermicompost, vermicompost 10 t/ha, vermicompost 15 t/ha. Second factor was dose of biourine Plus i.e without biourine plus, biourine plus 1500 l/ha, biourine plus 2000 l/ha. Observed variables were height plants, numbers of leaves, number of tubers, fresh weight of tuber, and dry tuber weight. Data were analysed by F test followed by LSD at 5%. It was concluded that the vermicompost and biourine plus dose treatment produced a significant impact on plant height and number of shallot leaves but had no effect on shallot yields. Vermicompost 15 t/ha is able to increase the harvest weight of shallots (fresh weight) by 14% and increase the dry weight of tubers by 17.45%.

Simulation of soil phosphorus dynamics and crop yield for organic and mineral fertilization treatments at two long-term field sites

The efficacy of phosphorus (P) based fertilizers is frequently compromised by soil dynamics that render much of the applied P unavailable for crops. This study aimed to: (i) validate a new P model's prediction of plant-available P; (ii) analyze the effects of organic versus mineral fertilization on P availability and crop yield; and (iii) examine temporal changes in P pools under various fertilization regimes. Data were collected from two long-term field trials, Dikopshof and Bad Lauchstädt, in Germany, using organic (FYM), mineral (MIN), a combination of organic and mineral (MIX) fertilizers, and unfertilized treatments. The AgroC model, incorporating a new P module, accurately predicted P dynamics in cropped plots. At both sites, MIX presented the highest yield, P removal, total P and available soil P. After 120 years of repeated P fertilization, simulations at Dikopshof revealed a positive P balance in MIN (11.1 % with observed 13 %) and in MIX (15 % with observed 15 %), but negative in FYM (−4.9 % with observed −5 %). However, at Bad Lauchstädt, the P balance was negative in all treatments except in MIN (+1.04 %), indicating P depletion. Among crops, cereals showed the most variated yields, with P-use efficiency ranging from 50 % to 99 %, while sugar beet presented the highest P-use efficiency (up to 122 %). The lowest P application rates exhibited, FYM treatment, the highest P-use efficiency for all crops. Model pools were successfully linked to field-measured soil P fractions using CAL and DGT methods, providing initial predictions of various soil P fractions across different fertilization strategies.

Two-successive greenhouse experiments were conducted at the protected cultivation department in Zakho Technical Institute, Dohuk Polytechnic University, Kurdistan region of Iraq during the seasons of 2021-2022 and 2021-2022 to inspect the growth and yield response of broccoli cultivar (Agassirz) to foliar application of humic acid and seaweed extract at concentration of 0, 2, and 4 ml.L-1 for the both and using of organic fertilizer (animal manure) at three levels 0, 5, and 10 ton.ha-1. The treatments were organized in a randomized complete block design (RCBD) with three replicates. The obtained data revealed that the foliar application of humic acid and seaweed extract at concentration of 4 ml.L-1 and organic manure of 10 ton.donum-1 resulted in significant increase in vegetative traits of plant height (cm), number of leaves.plant-1, and number of head per plant and yield attributes of head weight (g), head dry matter (%), and yield (kg.m2), Whereas the humic and seaweed at concentration (2) ml.L-1 and organic manure applied at 10) ton.donum-1 importantly affected the fresh weight of vegetative growth. The topmost ever values were produced from the triple treatment; humic acid at (4) ml.L-1 ) + seaweed at (4) ml.L-1 + organic fertilizer at (10) ton.donum-1 in comparison with control and other doses.

Evaluation of Organic Waste Long-Term Effects on Cellulose, Hemicellulose and Lignin Content in Energy Grass Species Grown in East-Central Poland

Biomass can be used for electricity generation, especially in developing countries, but also in developed ones, where the utilization of renewable energy sources is being integrated into a sustainable economy. There are considerable differences in the scale of biomass use and in the technology of its processing. One of the most important sources of biofuel is the biomass of grass. This research aimed to determine the long-term effects of organic fertilizers on cellulose, hemicellulose, and lignin content in the biomass of three grass species: giant miscanthus (Miscanthus × giganteus), prairie cordgrass (Spartina pectinata), and switchgrass (Panicum virgatum L.) in the first three years of growth. The experiment was established in four replications on microplots of 2 m2 in April 2018. Before planting grass rhizomes, municipal sewage sludge (SS) and spent mushroom substrate (SMS) were introduced into the soil in various combinations. Biomass is harvested in December every year. The content of structural polysaccharides in the grass species statistically significantly varied in response to organic waste. Compared to other fertilizer combinations, SS application increased the content of cellulose in the biomass of Miscanthus giganteus (43.66% of DM) and Spartina pectinata (37.69% of DM) and hemicellulose in Spartina pectinata (27.80% of DM) and Panicum virgatum (23.64% of DM). Of the three species of grass, the chemical composition of Miscanthus giganteus cell walls was the most favorable for biofuel production, with the most cellulose and hemicellulose and the least lignin compared to other grass species. The content of lignin in the biomass of Miscanthus × giganteus and Spartina pectinata was the greatest on the plot with SMS and amounted to 7.79% of DM and 12.32% of DM, respectively. In the case of Panicum virgatum, the average content of lignin was similar across all fertilized plots, with 15.42% DM.

The combined application of organic and inorganic fertilizers improved the quality of colored wheat by physicochemical properties and rheological characteristics of starch

Excessive use of nitrogen fertilizer can degrade the quality of wheat grain, while appropriate use of organic fertilizer can enhance starch quality. To clarify the effects of chemical fertilizer and organic fertilizer on wheat quality. We measured indicators such as amylose content, starch granules, starch structure, gelatinization characteristics, and rheological properties of wheat under different proportions of combined application of organic fertilizer and chemical fertilizer, revealing the effects of combined application of organic fertilizer and chemical fertilizer on the physicochemical properties and structure of starch. The results showed that compared with single application of chemical fertilizer (T1), organic fertilizer instead of 30 % fertilizer (T2) significantly increased amylose content (10.13 %), starch solubility (35.54 %, 90 °C), swelling power (7.40 %, 90 °C) and wheat yield (18.78 %), but decreased relative crystallinity (37.40 %) and order degree of starch, resulted in a decrease in gelatinization temperature (3.27 %). Meanwhile, rheological analysis also proved that the starch under T2 showed strong elasticity and hardness. This research highlights the importance of organic fertilizer for grain quality and propose that replacing 30 % of chemical fertilizer with organic fertilizer could significantly enhance the starch structure of colored wheat, providing theoretical support for the improvement of wheat quality.

Microbial decomposer for crop residue management in rice-wheat cropping system.

Crop residue management is vital in the rice-wheat cropping system, influencing soil health and crop productivity. This study examined the effects of organic and inorganic fertilizers and microbial decomposers on rice growth and yield. We evaluated seven treatments: 100% recommended dose fertilizer (RDF); 50% residue + 50% RDF; 50% residue + 50% RDF + Pusa decomposer; 50% residue + 50% green manuring (GM)/green leaf manuring (GLM); 50% residue + 50% GM/GLM + Pusa decomposer; residue @ 2.5 tons per acre + Pusa decomposer; residue @ 2.5 tons per acre + no Pusa decomposer; and absolute control. Results indicate that integrating organic and inorganic fertilizers with microbial decomposers positively affects rice growth and yield parameters. While adding microbial decomposer to RDF did not consistently enhance rice yield, it improved soil enzymatic properties. This suggests that the effectiveness of microbial decomposers may vary based on specific soil and crop conditions. Therefore, microbial decomposers present a promising approach to boost soil health and fertility. Further research is needed to optimize conditions for their use and systematically assess their impact on crop yields.

Effects of Organic Fertilizer Replacing Some Nitrogen Fertilizers on the Structure and Diversity of Inter-Root Soil Fungal Communities in Potato

The aim of this study was to investigate the effects of organic fertilizer replacing part of the nitrogen fertilizers on the structure and diversity of the inter-root soil fungal communities of potatoes. By carrying out a field trial in Gaoquan Village, Tuanjie Town, Dingxi City, Gansu Province, the main potato-producing area in China, the optimal proportion of organic fertilizer to replace nitrogen fertilizer was determined to provide a scientific basis for the rational use of organic fertilizer to improve the structure and function of soil fungal communities. The experiment was laid out with six treatments: CK (no nitrogen fertilizer, phosphate and potash fertilizer applied), CF (nitrogen fertilizer alone, control), T1 (25% replacement of nitrogen fertilizer), T2 (50% replacement of nitrogen fertilizer), T3 (75% replacement of nitrogen fertilizer), and T4 (100% replacement of nitrogen fertilizer). A systematic study of the inter-root soil fungal community structure, diversity, and soil physicochemical properties during potato harvesting was conducted using high-throughput sequencing technology. The results show that the organic fertilizer replacing part of the nitrogen fertilizer significantly increased the content of alkaline dissolved nitrogen, quick-acting potassium, quick-acting phosphorus, and organic matter in the inter-root soil of the potatoes, and significantly reduced the pH value of the soil. There was a trend of decreasing soil fungal abundance and a significant decrease in the Alpha diversity of the soil fungi. The treatment groups in the soil had as their core fungi Acomycota, Mortierellomycota, Basidiomycota, and others. The organic fertilizers replacing the nitrogen fertilizers significantly altered the structural composition of the inter-root soil fungal community of the potatoes, and increased the differential fungi in the soil. The number of functionally diverse and complex fungi in the soil gradually increased, and the function of the fungal community gradually changed from Singularity to diversification and complexity. A redundancy analysis showed that the soil pH was the main environmental factor affecting the inter-root soil fungal communities of potatoes under organic fertilizer replacing N fertilizer.

Effect of Organic Fertilization Based on Cattle Dung in Village Cultivation of Sugar Cane (Saccharum officinarum L.) in Immature Phase in Northern Ivory Coast

This study aimed to determine the dose of organic fertilizer adapted to the agroecological conditions of the Ferkéssédougou zone during the immature or vegetative phase with a view to improving agricultural productivity in rainfed sugar cane cultivation. The trial was conducted using a Fisher block experimental design with three (3) repetitions and six (6) treatments including the control treatment. The observations mainly focused on growth parameters. Health monitoring was also carried out to detect the presence of diseases. Regarding growth parameters, no statically significant effect of fertilizers was observed between treatments. However, the fertilizers used had a positive impact in terms of gain compared to the control. Thus, three (3) groups of fertilizers stood out. Group 1 was composed of mineral manure at the normal dose (350 kg/ha of NPK), organic manure at the normal dose (20t/ha), double dose of compost (40 t/ha) and the organo-mineral mixture, namely the normal dose of compost (20t/ha) + half dose of mineral fertilizer (175 kg/ha of NPK). These treatments promoted good emergence, good elongation of the plants with large diameters and a large number of internodes. Group 2, composed only of half a dose of compost (10 t/ha), allowed us to have a large number of stems. For group 3, corresponding to the control treatment, no growth parameter was correlated. No symptoms of major illnesses were observed during the observations. The M1400/86 variety used is resistant to termite attack.
