Introduction: The Okra (Abelmoschus esculentus) is an essential vegetable crop widely cultivated for its nutritional, medicinal, and economic benefits. It is a rich source of vitamins, minerals, fiber, and antioxidants, making it a staple in many diets across Nigeria and beyond. In Kebbi State, okra farming plays a significant role in food security and income generation for smallholder farmers. However, achieving optimal growth and yield remains a challenge due to soil fertility depletion and inadequate fertilization practices. Fertilization is a crucial factor in crop production, influencing plant growth, development, and yield quality. Farmers commonly use both organic and inorganic fertilizers to enhance soil fertility and improve crop performance. Organic fertilizers, such as compost and animal manure, improve soil structure, water retention, and microbial activity, contributing to long-term soil health. In contrast, inorganic fertilizers, particularly nitrogen-phosphorus-potassium (NPK) formulations, provide readily available nutrients that promote rapid plant growth and high yields. Despite their benefits, excessive or improper use of inorganic fertilizers can lead to soil degradation and environmental concerns. This study aims to compare the effects of organic and inorganic fertilization techniques on okra growth and yield in Kebbi State. By evaluating key agronomic parameters such as plant height, leaf count, flowering rate, and pod yield, this research seeks to identify the most effective and sustainable fertilization method for optimizing okra production. The findings will provide valuable insights for farmers, agricultural extension workers, and policymakers in promoting sustainable and profitable okra farming practices. METHODOLOGY Study Area This study was conducted in Kebbi State, Nigeria, a region known for its predominantly agrarian economy. Kebbi State is characterized by a tropical climate with distinct wet and dry seasons, making it suitable for okra cultivation. The study site was selected based on its accessibility, history of okra farming, and soil characteristics. The soil type in the study area is sandy- loam, which is common in the region and supports the growth of various crops, including okra. The average annual temperature ranges between 26°C and 39°C, with an annual rainfall of approximately 800-1,000 mm, American Journal Of Agriculture And Horticulture Innovations 2 https://theusajournals.com/index.php/ajahi American Journal Of Agriculture And Horticulture Innovations (ISSN: 2771-2559) which provides adequate moisture for plant growth. Experimental Design A field experiment was established using a randomized complete block design (RCBD) with three replications to minimize variability and ensure reliable results. The study consisted of three treatment groups: (1) organic fertilization, (2) inorganic fertilization, and (3) a control group with no fertilization. Each treatment was applied to a designated plot, with each plot measuring 3m x 3m. A buffer zone of 1 meter was maintained between plots to prevent nutrient crossover between treatments. The experiment was conducted during the rainy season to take advantage of natural precipitation, reducing the need for artificial irrigation. Soil Preparation and Fertilizer Application The experimental plots were cleared, plowed, and harrowed to improve soil aeration and create a suitable seedbed for planting. Soil samples were collected before planting to analyze nutrient content, pH level, and organic matter composition. The organic fertilizer used in the study was well-decomposed poultry manure, applied at a rate of 10 tons per hectare, as recommended for vegetable crops. The inorganic fertilizer used was NPK 15-15-15, applied at a rate of 200 kg per hectare. The organic fertilizer was incorporated into the soil two weeks before planting to allow for decomposition, while the inorganic fertilizer was applied in two split doses—the first at planting and the second four weeks later, ensuring efficient nutrient uptake by the plants. Okra Variety and Planting Procedure The okra variety used in the study was Clemson Spineless, a widely cultivated variety known for its high yield and adaptability to different environmental conditions. Seeds were sourced from a certified agricultural supplier to ensure quality and uniformity. The seeds were sown directly into the field at a depth of 2 cm, with a spacing of 60 cm between rows and 30 cm between plants. Each plot contained 25 plants, ensuring adequate replication for statistical analysis. Thinning was performed two weeks after germination to maintain a uniform plant population. Agronomic Data Collection To assess the effects of different fertilization methods on okra growth and yield, various agronomic parameters were recorded at different growth stages. Data collection was conducted at weekly intervals, beginning two weeks after planting. The key parameters measured included: Plant Height: Measured from the base to the tip of the tallest leaf using a measuring tape. Number of Leaves per Plant: Counted manually to assess vegetative growth. Flowering Rate: Recorded as the number of flowers per plant to determine reproductive development. Pod Yield: Harvested pods were counted, weighed, and recorded to evaluate overall productivity. Statistical Analysis Data collected from the experiment were subjected to statistical analysis using Analysis of Variance (ANOVA) to determine significant differences among treatments. Mean comparisons were conducted using the Least Significant Difference (LSD) test at a 5% significance level (p<0.05). Statistical software such as SPSS or R was used for data processing and analysis. Graphs and tables were used to present the results clearly and concisely. Environmental and Management Considerations The experiment was conducted under natural field conditions, with minimal external interventions apart from the application of fertilizers. Weeds were controlled manually to prevent competition for nutrients, and pests were managed using organic methods to minimize external chemical influence. The study also considered environmental sustainability by assessing soil health before and after the experiment to determine the long-term effects of organic and inorganic fertilization on soil quality. Ethical Considerations The study adhered to ethical guidelines for agricultural research, ensuring that no harmful chemicals were used beyond recommended agricultural practices. Local farmers were engaged and informed about the purpose of the study, with knowledge-sharing sessions conducted to enhance awareness of sustainable fertilization practices. The findings of the study were shared with relevant agricultural extension officers to support local farmers in optimizing okra production. RESULTS The results of the study showed significant differences in okra growth and yield among the treatment groups. The plants treated with inorganic fertilizer exhibited the highest plant height, leaf count, and early flowering rate compared to those treated with organic fertilizer and the control group. However, organic fertilizer treatment resulted in improved soil structure and long- term fertility benefits. The control group had the lowest growth performance, indicating the importance of fertilization in optimizing okra production. Pod yield was significantly higher in inorganic fertilization plots, followed closely by organic fertilization, while the control plots recorded the lowest yield.

However, the long-term benefits of organic fertilization, such as improved soil health and sustainability, cannot be overlooked. While inorganic fertilizers provided quick nutrient availability, their excessive use could lead to soil degradation over time. The study suggests that a combination of both organic and inorganic fertilization may be the most effective strategy for maximizing okra production while maintaining soil fertility in Kebbi State. CONCLUSION This study demonstrated that fertilization plays a critical role in optimizing okra production in Kebbi State. Inorganic fertilizers resulted in higher yield and faster growth, whereas organic fertilizers contributed to long-term soil health and sustainability. Based on these findings, it is recommended that farmers adopt an integrated fertilization approach, combining both organic and inorganic methods, to enhance crop productivity while preserving soil quality. Further research is suggested to explore the long-term effects of different fertilization techniques on soil properties and yield stability in subsequent farming seasons.
