Abstract
Tomato (Solanum lycopersicum L.) production requires sustainable fertilization practices to improve productivity while reducing dependence on synthetic fertilizers. This study evaluated the effects of different BioDeposit Elixir organic fertilizer application rates on the agronomic and economic performance of two tomato varieties under field conditions in Côte d’Ivoire. A field experiment was conducted during the 2024-2025 cropping season using a randomized complete block design with a factorial arrangement of two varieties (Petomech+ and Cobra 26 F1) and five application rates (0, 12, 15, 20, and 25 mL per 10 m²), with three replications. Morphological, phenological, yield, fruit quality, postharvest, and economic traits were evaluated. Data were analyzed using two-way analysis of variance followed by the Newman–Keuls multiple range test at P < 0.05. BioDeposit Elixir significantly affected most traits. Significant variety × BioDeposit Elixir dose interactions were observed for stem collar diameter, plant height, flowering time, fruit diameter, fruit fresh weight, gross yield, and shelf life. The 25 mL rate generally produced the highest values. Cobra 26 F1 showed superior performance for several traits, including plant height, fruit diameter, gross yield, and shelf life. The number of leaves, number of flowers, fruit appearance, harvest timing, and blossom-end rot incidence were mainly affected by the variety and/or BioDeposit Elixir dose without significant interaction. The 25 mL rate also resulted in the highest net economic value under both selling price scenarios (700 and 900 XOF kg⁻¹). Overall, BioDeposit Elixir improved several agronomic, postharvest, and economic traits, with responses depending on the trait and variety. The 25 mL rate provided the best overall performance under the experimental conditions.
The increasing demand for sustainable tomato production has intensified the search for environmentally friendly nutrient management strategies that can improve crop productivity while maintaining soil health. This study evaluated the effects of different rates and combinations of vermicast and vermitea on the growth, yield, fruit quality, postharvest performance, and profitability of tomato (Solanum lycopersicum L.) under the agroecological conditions of Ilocos Sur, Philippines. The experiment was conducted using a Randomized Complete Block Design (RCBD) with six treatments and three replications. Growth parameters, flowering characteristics, yield components, fruit quality, postharvest attributes, and economic returns were analyzed using Analysis of Variance (ANOVA). Results revealed that vermicast and vermitea significantly influenced all measured parameters (P ≤ 0.01). The combined application of 80 g vermicast + 1000 ml vermitea per 16 L water (T3) consistently produced the best overall performance, recording the highest final plant height (86.37 cm), height increment (75.43 cm), number of leaves (86.00), flowers (53.00), fruits per plant (41.00), average fruit weight (98.27 g), total fruit yield (4.02 kg plant⁻¹), marketable yield (21.43 t ha⁻¹), and market quality (97.56%). The same treatment also extended shelf life, minimized fruit cracking, and generated the highest gross income (₱642,000.00 ha⁻¹), net income (₱447,596.24 ha⁻¹), return on investment (230.24%), and benefit-cost ratio (3.30). Meanwhile, vermitea applied alone enhanced stem diameter, fruit firmness, fruit size, and accelerated flowering. Overall, integrating vermicast and vermitea proved to be an effective and economically viable organic nutrient management strategy for improving tomato growth, fruit quality, yield, and profitability. The study demonstrates the potential of vermicompost-based amendments as sustainable alternatives to synthetic fertilizers for enhancing tomato production under local farming conditions.

The increasing demand for sustainable and environmentally friendly agricultural practices has stimulated interest in the use of organic bio-fertilizers as alternatives to synthetic fertilizers. This study evaluated the effects of banana peel and eggshell liquid bio-fertilizers on the growth and yield of onion (Allium cepa L.) and fluted pumpkin (Telfairiaoccidentalis). The experiment was conducted at Gombe State University Botanical Garden using a Completely Randomized Design (CRD) with three replicates. Banana peel and eggshell liquid bio-fertilizers were applied at 25, 50, 75, and 100 mL, alongside an NPK fertilizer treatment and an untreated control. Growth parameters, chlorophyll content, biomass, yield, and nutrient composition were evaluated, and the data were analyzed using analysis of variance (ANOVA). Most measured growth and yield parameters showed no statistically significant differences among treatments (P > 0.05), although some bio-fertilizer treatments produced numerically comparable responses to the NPK fertilizer under the conditions of this study. The findings indicate that banana peel and eggshell liquid bio-fertilizers may serve as promising organic nutrient sources for vegetable production. However, given the largely non-significant treatment effects and the controlled sack-culture conditions of the experiment, further field-based studies with larger sample sizes and diverse environmental conditions are required before recommending their widespread agricultural use.

The excessive dependence on synthetic fertilizers in crop production has raised concerns regarding soil degradation, environmental sustainability, and long-term agricultural productivity. Vermicompost represents a promising organic nutrient source; however, its effectiveness in improving crop performance may vary depending on application rate and crop genotype. This study evaluated vermicompost as a sustainable biofertilizer for improving growth and yield of cowpea (Vigna unguiculata L.). A factorial experiment was conducted to evaluate the effects of vermicompost application levels and cowpea genotype on growth and yield performance. Four cowpea varieties were tested under four vermicompost-to-soil ratios of 25:75, 50:50, 75:25, and 100:0 together with chemical fertilizer and untreated control treatments. Growth and yield parameters were analyzed using analysis of variance in Minitab 15. Vermicompost significantly enhanced vegetative growth and reproductive performance compared with the control and chemical fertilizer treatments (p < 0.05). Improvements were evident across all vermicompost levels, with 25–75% applications already producing substantial gains in growth and yield attributes. Maximum values were generally observed at the 100% level, including plant height (50.94 ± 3.00 cm; Bombay), leaf number (39.00 ± 1.22; MI 35), branch number (14.20 ± 1.48; MI 35), nodes per main stem (20.00 ± 2.45; MI 35), and leaf area index (79.26 ± 14.97 cm²; Bombay). Yield-related traits also responded positively to vermicompost, as indicated by earlier flowering (35 ± 0.83 days; Waruni and Dawala), earlier maturity (47.40 ± 1.14 days; Waruni), longer pods (16.24 ± 0.68 cm; ANKCP 2), higher seed number per pod (11.00 ± 1.58; ANKCP 2), greater pod number per plant (4.40 ± 1.14; Waruni), and increased seed size (0.72 ± 0.08 mm; Bombay). Vermicompost showed beneficial effects under the tested pot conditions; however, further field validation is necessary to assess its effectiveness and suitability as a partial or complete alternative to conventional fertilizers.

A field experiment was conducted during Kharif 2022 and 2023 at Dr. BRC Agricultural Research Station (ARS), Mandor, Rajasthan, to evaluate the effect of biofertilisers and growth-promoting microorganisms on growth, yield, and profitability of mungbean (Vigna radiata (L.) Wilczek, var. GM-4) under the mungbean–wheat cropping system. The experiment was laid out in a Randomised Block Design with ten treatments and three replications. Treatments consisted of different combinations of the recommended dose of fertilisers and seed inoculation, soil application, or combined seed and soil application of Rhizobium and phosphate-solubilising bacteria (PSB). The results indicated that growth parameters, yield attributes, grain yield, biological yield, and economic returns were significantly influenced by the treatments. The greatest numerical plant heights at 30 DAS (46.8 cm) and 45 DAS (55.9 cm) were recorded under T₁₀, while T₅ recorded comparable values of 45.8 and 55.3 cm, respectively. The highest numbers of pods per plant (39.6) and seeds per pod (13.5), dry matter production (3.50 t ha⁻¹), and test weight (48.1 g) were observed under T₅, whereas the highest numerical chlorophyll content (4.00 mg g⁻¹) was recorded under T₁₀. The highest grain yield (pooled: 1458 kg ha⁻¹) and net return (₹98,855 ha⁻¹) were recorded with 100% RDF (T₅), whereas 75% RDF combined with seed and soil application of Rhizobium + PSB (T₁₀) produced a pooled grain yield of 1400 kg ha⁻¹ and a B:C ratio of 4.41, remaining statistically at par with T₅. Thus, integrated use of biofertilisers with 75% RDF can reduce fertiliser requirement without significant yield loss and improve profitability.

Chemical fertilisers can support crop production but may create environmental and accessibility concerns, prompting interest in locally available organic inputs. This study evaluated the effects of powdered material and aqueous extracts of Chromolaena odorata on the agromorphological performance and yield of Clemson spineless and Hiré okra varieties in Taabo, southern Côte d’Ivoire. The experiment comprised three completely randomised blocks with three replicates and fourteen treatments. Powdered material was applied at 5, 15, and 25 g, while aqueous extracts were applied at 5, 15, and 25 g/L. Treatments were applied four times at two-week intervals before, at, and after sowing. Germination, survival, leaf area, plant height, collar diameter, number of leaves, number of fruits per plant, and fruit weight were assessed. Germination ranged from 83.33% to 100%, while survival ranged from 97.50% to 100%. Extract application generally improved growth and yield relative to the controls. The 25 g/L aqueous treatment produced the highest leaf area in Clemson spineless (225.94 cm²) and the highest collar diameter (0.87 cm), mean fruit number (6.29), and mean fruit weight (28.58 g) in Hiré. Across extract forms, the aqueous treatments generally produced stronger responses than the powdered material, except for the number of leaves, for which the two forms were statistically similar. Under the conditions of the study, Chromolaena odorata aqueous extract, particularly at 25 g/L, showed potential as a locally available organic input for okra production.

Oil palm (Elaeis guineensis Jacq.) is one of the most efficient agricultural systems for vegetable oil production; however, its productivity depends critically on the quality of nursery seedlings, where fertilization plays a determining role in structural development and in the economic efficiency of the system. The objective of this study was to evaluate the agronomic and economic performance of different fertilization strategies by comparing compound fertilizers (T1: 10-30-10; T2: YaraMila; T3: Urealina) against simple fertilizers (T4), using an experimental approach and cost-benefit analysis. A randomized complete block design was used, and growth indicators were evaluated, including plant height, leaf dimensions, stem diameter, and number of leaves. The results showed significant differences at p ≤ 0.05 according to Tukey's test, with compound treatments showing greater structural development; T1 stood out with the highest values for all variables evaluated, whereas T4 showed the lowest performance. From the economic perspective, T1 recorded the lowest cost and the highest cost-benefit ratio (2.19), followed by T2 and T3 with marginal differences, while T4 showed substantially lower efficiency (1.35), attributed to increased operating costs. The results demonstrate that balanced fertilization simultaneously optimizes seedling growth and system profitability, consolidating it as a key strategy for efficient production in oil palm nurseries.
