Germination is defined as a plant emerging from a seed after a period of dormancy.1 A research question is formed; ‘Does different soil depths have an effect on germination speed of the Lens culinaris seeds?’ An experiment is designed to investigate. Lens culinaris seeds are used, because the volume and shape of the seed being convenient. The volume and mass of Lens culinaris seeds are small, and the shape is round. These features are the perfect fit for the experiment, because the depth of the seeds will be changed and it is important to reduce the errors while planting the seeds. There are also lots of types of Lens culinaris seeds for example, Indian brown, French Green, Red Chief lentil…2 In the experiment, Indian brown lentil seed types are used, this type of seed can be found in every grocery store. 35 seeds were planted in 35 cups with different depths each 5 trial. They were all tried to be kept in same conditions and each of them was watered 10 ml day by day. The day and time were recorded when the seeds planted and the time when seeds germinated, and by this process, the time taken for the germination is calculated. The germination process of the seeds in all of the trials was controlled per 2 hours between the hours 08:00 and 23:00 pm. After the experiment, the results confirmed the alternative hypothesis. ANOVA One Way statistical analysis is made to compare the data in the experiment. The p-value found in this analysis was 1.57 x 10-5, which is smaller than the alpha value(0.05). Therefore, the Lens culinaris seeds planted near the surface emerged from the soil quicker than the other seeds.
