Potassium fertilization in radish plants: Production and quality of tuberous roots

Abstract

The application of mineral fertilizers provides advantages, especially in short-cycle crops such as radish. This is because it contains high concentrations of nutrients that make plants available faster, in addition to being easy to handle compared to organic fertilizers applied to the soil. The objective of this study was to evaluate the agronomic performance of radish under the effect of the application of different doses of potassium fertilizer in the region of Bom Jesus-PI. The experiment was conducted in the field in an experimental area of the Federal University of Piauí, at the Campus Professora Cinobelina Elvas, located in the municipality of Bom Jesus-PI. The treatments consisted of six doses of K using potassium chloride as a source of the nutrient. The experimental design was randomized blocks consisting of six treatments (K doses) with four replications. The results obtained with the application of potassium fertilizer suggest that the radish crop responds positively and differently to increasing doses of potassium. The different rates of topdressing potassium fertilization influence the productive attributes of radish plants and the P, K and M.O. contents of the soil. The increase in K doses applied in topdressing promotes higher plant yields when compared to the non-application of this nutrient. Under the conditions in which the experiment was carried out, it is recommended to provide 400 kg ha^-1 of K2O for radish cultivation.
