Tobacco growth - Lab Report ExampleThe reflect recommends growth of Burley tobacco in artificial dirty word. Research questions The study sought to investigate the chase interrogation questions. Does the soil type affect germination of plants? Does the soil type affect the growth of plants? Hypotheses In bless to answer the investigate questions, the research explored the following come outs of hypotheses, Ha1 A= P= O there is no world-shaking diametric on the effect of type of soil on germination of tobacco. (Where A, P, and O are the take to be part of germinated seeds for artificial, plain, and organic soils respectively) Ho1 Any of the A, P, or O is different there is a significant loss in the soils effects on the ability of tobacco to germinate. Ha2 A= P= O There is no significant difference on the effects of type of soil on the tobaccos grow. (Where A, P, and O are the mean length of the plants for artificial, plain, and organic soils respectively) Ho2 Any of the A, P, or O is different there is significant differences in the soils effects on the ability of tobacco grow. Materials and methods Materials The following materials were used in the experiments Burley tobacco seeds, 15 small growers pots, labeling stickers, three different types of soil (artificial, plain and organic), rest spray, tweezers, spatula, water, and zip-ock-bags. Design The research applied a complete randomized design in its experimental set up. The design involves separate blocks for experiments and from each one block has the same number of treatment. The design was selected for its advantages that would facilitate exploration of the research questions and the research hypotheses. One of its advantages is its level of precision that also eliminates error because of existence of control. It also offers more cultivation as compared to other designs because treatments across all blocks can be paired during analysis. The design is also dewy-eyed to implement and is flex ible. It is however suitable for blocks with relatively small sizes (Montgometry and Runger, 2010). Research procedure The research growth mired acquisition of 15 small growers pots that were labeled with the groups identification number. The pots were form for three treatments and each treatment had five replicates that were achieved in five different pots and were each labeled. Each of the pots was alter to 1 inch below the top with the appropriate soil. Using a light spray from the hose, the soil was saturated, evenly, so that it settled. One more inch of soil was then added to the saturated soil from the top and watered. The process was repeated until the potting mix no longer settled. Tweezers was then used to disperse 10 tobacco seeds into a small beaker before the 10 seeds were evenly and randomly distributed across the surface of each pot. Care was interpreted to get exactly 10 seeds into each pot. Each pot was then slowly dipped into a pan of water until saturation was achieved. Watering from the bottom technique was used, throughout the study, to achieve this. The pots were then certain in their own labeled Zip-Lock bag and placed, randomly, under grow lights as directed. Once a week, we went trim as a group to count how many plants had germinated and watered our plants. We placed a toothpick next to each sprout to mark its location for analytics purposes in case germinated seeds dried up. At the end of the study, we determined the percentage germination and
