Effect of Treatment with Grounded Bay Leaf on the Physiological Quality of Bean Seeds Stored at Room Temperature

Quality seeds are important inputs for agriculture and form the basis of a healthy and productive crop. The practice of seed storage by family farming often takes place in environmental conditions of uncontrolled temperature and humidity and under potential risk of attack by insects and pathogens. In this scenario, the use of plants with insecticidal and fungicidal active principles has acquired great importance in order to maintain sanitary and physiological quality. The objective of this work was to evaluate the effect of bean seed treatment with bay leaf on the physiological and sanitary quality of seeds stored at room temperature. The seeds were treated with concentrations of 1%, 2.5% and 5% w/w (measured in g/kg) and stored at room temperature in multiwall paper bags for a period of 24 months. The results indicate a decrease in germination after 24 months of storage for all treatments studied. The treatment of Manteigão bean at 1% powdered laurel showed better germination maintenance for 24 months and less leaching of potassium, calcium and magnesium ions, showing that this variety is more resistant than Amarelinho bean to storage at room temperature under the conditions of the study.
