This paper describes an experiment with factorial design and two levels of treatment, used in testing fertilizer applications for tobacco seed beds. The fertilizers employed were : Chilean nitrate, superphosphate, potassium chloride, and cotton seed meal. Tobacco plants were grown in ten liter clay pots containing a steam sterilized soil composed of equal parts* of thoroughly mixed sub-soil and surface washed sand. Each of the sixteen treatments tested was applied to six pots and these were divided into three replications of two pote each. Measurements of height and weight of the plants were taken about two months after the seed germinated. An analysis of the data obtained is presented and shows that under the conditions of the test, all fertilizer applications which contained phosphate had a significant influence on plant growth. The NPK treatment was found to be the most advantageous. It was further determined that nitrogen and potash had a significant effect on plant growth in a group of eight treatments analyzed.
