Effect of Different Organic Manures and Organic NPK on Growth and Yield of Radish (Raphanus sativus L.)

Abstract

This research investigates the influence of different organic manures and an organic NPK mixture on the growth and yield of radish (Raphanus sativus L.). Radishes are known for their nutritional benefits and are widely consumed across the globe. However, the use of synthetic fertilizers has led to concerns regarding soil health and environmental sustainability. This study was conducted to explore organic alternatives and develop sustainable cultivation practices. The experiment was designed using a randomized complete block design (RCBD) with seven treatments, including a control, and five replications. The treatments include compost, paddy compost, bonemeal, neem cake, vermicompost, and rice husk charcoal, combined with an organic NPK mixture made from dry tea dust, eggshell dust, and banana peels. Data were collected on various growth parameters, including plant height, leaf size, and root length, as well as yield parameters such as total biomass and fresh root weight. The results demonstrated that rice husk charcoal (T6) led to the highest yield and plant growth, whereas neem cake (T4) exhibited the lowest results. The research findings emphasize the potential of organic manures, particularly rice husk charcoal, combined with organic NPK, to enhance radish cultivation, offering insights into eco-friendly farming practices. Future studies are recommended to investigate the long-term effects on soil health and expand to other crops.
