How does the application method and frequency of fertilizers impact okra yield and quality?
Best insight from top research papers
The application method and frequency of fertilizers significantly impact okra yield and quality. Different studies have shown that fertilizer types, doses, and combinations influence various aspects of okra growth and productivity. For instance, the use of Effective Microorganisms (EM) and Bokashi has been found to enhance the growth and yield performance of okra, with Bokashi alone delivering the highest mean value of products. Nitrogen (N) fertilization has shown a direct relationship with photosynthesis, vegetative growth, and productivity of okra plants, emphasizing the importance of nitrogen in okra development. Additionally, the integrated use of organic manures and NPK fertilizers has been shown to significantly increase the growth and total yield attributes of okra, highlighting the positive impact of organic inputs on okra quality and yield.

How does the timing and frequency of fertilizer application impact the yield and quality of crop production?5 answersThe timing and frequency of fertilizer application can impact the yield and quality of crop production. In a study on corn and soybean systems in the Midwestern USA, it was found that different nitrogen (N) fertilizer timings did not significantly affect crop yield, but split-applied urea had a small positive impact on water quality. Another study on off-season tomato production found that specific timing of fertilizer application, with NPK fertilizer applied at 7-day intervals, resulted in higher fruit yield and improved quality characteristics such as weight, density, and protein content. In wheat production, the timing of N fertilizer application was found to influence grain yield and protein content, with the highest yield observed when fertilizer was applied in spring. Additionally, a study on corn performance in subtropical environments showed that the timing of potassium (K) fertilizer application did not affect corn performance, but early application resulted in higher K-fertilizer use by the crop. Long-term fertilization was found to improve crop yield, soil fertility, and soil nutrient content, with organic and organic-nitrogen fertilizers having the most significant effects.
How does the use of organic fertilizers affect the growth and yield of okra plants?4 answersThe use of organic fertilizers, such as FYM, vermicompost, and biochar, has been found to have a positive effect on the growth and yield of okra plants. Application of organic manures, either alone or in combination with inorganic fertilizers, significantly increased plant height, number of branches, number of leaves, number of fruits, and total fruit yield of okra. The combination of organic and inorganic fertilizers was shown to be the most effective in promoting okra production. Additionally, the use of slow-release fertilizer-manure blocks containing organic manures and fertilizers improved the growth and yield of okra, with treatments showing significant increases in fruit yield per plant, fruit length, fruit girth, and number of seeds per fruit. Overall, the incorporation of organic fertilizers in okra cultivation can enhance plant growth, yield, and nutrient content, making it a sustainable approach for okra production.
Effect of nitrogen on Okra growth?4 answersNitrogen has a significant effect on the growth of okra. The application of nitrogen fertilizer at different doses resulted in improved growth parameters such as plant height, number of branches per plant, and fruit length. The optimal dose of nitrogen varied across studies, with recommendations ranging from 90 kg N/hato 140 kg N/ha. Additionally, the use of organic nitrogen from compost was found to be more efficient for green okra compared to inorganic nitrogen fertilizer. Increasing nitrogen doses also led to increased nitrogen uptake, pods yield, and nitrogen use efficiency in both green and red okra. Overall, the application of nitrogen fertilizer, at the appropriate dose, is crucial for promoting the growth and yield of okra.
What is the recommended rate of NPK application for okra?3 answersThe recommended rate of NPK application for okra varies across the studies. Ibrahim et al. found that the combination of 150 kg/ha and 200 kg/ha NPK fertilizer produced the highest yield of okra. Ngegba et al. reported that the treatments with NPK rates of 90 kg/ha, 120 kg/ha, and 150 kg/ha resulted in taller plant heights compared to the treatment with no NPK fertilizer. Muhammad et al. concluded that the application of 800 kg NPK (15:15:15) ha-1 or a combination of 400 kg of NPK (15:15:15) ha-1 and 3.3 t of poultry manure ha-1 led to increased plant height, number of leaves, number of pods per plant, mean pod weight, mean pod length, and fruit yield per hectare. Rahman et al. found that the highest seed yield and good quality of okra seed were obtained from the application of 2 kg B and 4 kg Zn/ha in combination with the recommended dose of NPK fertilizers. Nwaoguala et al. did not provide specific recommendations for NPK application rate.
What are the details of data collection methods on growth and yield of okra?5 answersData collection methods on growth and yield of okra varied across the different studies. In one study, the growth and seed traits of sixteen okra lines were collected during wet and dry seasons using a General Linear Model (GLM), principal component analysis (PCA), and cluster analysis. Another study used an IoT system to collect information on humidity, soil moisture, and temperature, which was then displayed on a user interface (UI) and passed on to farmers' mobile devices. A third study examined the effect of methods of fertilizer application on growth and yield of okra, collecting data on plant height, number of leaves, stem diameter, and fruit weight. In a fourth study, data on growth parameters and yield attributes of okra were collected using a Randomized Complete Block Design (RCBD) and analyzed for the response to different mulching materials and rates of application. Finally, a fifth study collected data on the effects of nitrogen fertilizer rate on the growth and yield of okra, measuring plant height, area of leaves produced, and crop yield.
How to obtain recommended rate of NPK for okra using NPK 15:15:15?3 answersTo obtain the recommended rate of NPK for okra using NPK 15:15:15, several studies provide insights. One study found that the highest net income and benefit: cost ratio were observed with NPK @ 125-62-62 kg ha-1, while higher rates did not prove economical. Another study suggested that the optimum NPK 20-10-10 level for okra lies between 300-450 kg NPK 20-10-10/ha, and rates above 450 kg NPK 20-10-10/ha were not economical. Additionally, an experiment showed that the highest seed yield of okra was obtained with Azospirillum + recommended dose of NPK. Although the specific recommended rate of NPK 15:15:15 for okra was not mentioned in the abstracts, these findings can guide farmers in determining the appropriate NPK rates for okra cultivation.
