Exploring Synergistic Effects of Cowdung and Vermicompost on Radish (Raphanus sativus L.) Morphology and Yield

The integration of organic amendments in crop cultivation is gaining attention for its potential to improve soil health and boost radish yield in Bangladesh.The experiment was conducted at Noakhali Science & Technology University to evaluate the impact of organic manures on the growth and yield of radish.Using a randomized complete block design, the experiment included four treatments: T (no organic manure), 0 T (cowdung at 30 tha ), T (vermicompost at 30 tha ), and T (combination of cowdung and vermicompost at 15 tha each).Both cowdung andvermicompost significantly enhance radish cultivation compared to the control condition.Growth parameters, including plant height, leaf length, leaf breadth, and leaf number, showed the highest values in treatment T .Yield-contributing parameters, such as root length, root 3 diameter, root weight, and gross yield were also highest in treatment T with a gross yield of 17.73 t/ha.Conversely, the lowest values for both 3 growth and yield parameters, including a gross yield of 6.11 t ha , were observed in the control treatment (T ).The findings indicate that the -1 0 application of both cowdung and vermicompost significantly enhances radish growth and yield, with the combined treatment (T ) showing 3 superior performance compared to other treatments.
