Application of Biological Fertilizer with Different Application Time Intervals on the Development of Seedling Down Disease and Growth of Mustard (Brasica rapa) in Nurseries

Seedling fall disease caused by the fungus Rhizoctonia solani is one of the limiting factors in the cultivation of mustard plants. This pathogen can attack plants in the nursery as well as after the plants in the field. The aim of this study was to determine the effect of using biological fertilizers Azoto-Trico and consortium of phosphate solubilizing bacteria isolates with different application time intervals on the development of seedling fall disease and the growth of mustard in the nursery. The study used Azoto-Tricho and consortium of phosphate solubilizing bacteria isolates biological fertilizers with application intervals of two days, four days and six days. The results showed that the application of biological fertilizers Azoto-Tricho and KIBPF with different application time intervals had an effect on controlling seedling fall disease and increasing plant height and plant fresh weight. The application of Azoto-Tricho biofertilizer and consortium of phosphate solubilizing bacteria isolates if applied at intervals of two days or four days or six days had the same ability to control seedling fall disease and increase plant height and fresh weight of mustard plants in nurseries
