Yield reduction of soybean due to soybean mosaic virus transmitted by Aphis glycines
The experiment was conducted at Maros Experiment Farm from July to November 1989, to measure yield reduction of soybean caused by soybean mosaic virus (SMV), at different ages of inoculation, i.e. 10, 20, 30, 40, 50 and 60 days after sowing, using virullferous insect (Aphis glycines). A randomized c...

Summary: | The experiment was conducted at Maros Experiment Farm from July to November 1989, to measure yield reduction of soybean caused by soybean mosaic virus (SMV), at different ages of inoculation, i.e. 10, 20, 30, 40, 50 and 60 days after sowing, using virullferous insect (Aphis glycines). A randomized completed block design was used with three replications, plot size 4,0 m x 5,0 m and plant spacing was 40 cm x 20 cm, 2 plants/hill. Results of the experiment showed that there was correlation between age of inoculation and yield reduction, varied from 3.4-52.6 percent. Generally, yield reduction decreased with increase of plant age at the time of infection, the highest at 10 days after sowing (54.2 percent) and the lowest at 60 days after sowing (3.4 percent). Diseased plant as well as population of A. glycines were higher at the early stages of inoculation than attention to disease management must be made and should be applied at early stage of growth to minimize yield reduction. |
