Sweet sorghum (Sorghum bicolor (L.) Moench) is a crop that is cultivated worldwide for its sugar rich stalks, grain, biofuel production and forage. In Botswana it is produced on a small scale level for subsistence as well as economic purposes. Even though the crop is well adapted to the conditions in the country, its production is faced with some challenges that affect its economic value. These include a reduced internode length and diameter as well as low sucrose levels in the stem juice. In order to deal with challenges there is a need to come up with ways to increase both internode length and sucrose levels in stem juice so as to increase the economic value of the crop. Recently, the use of phytohormones to improve crop quality and yield has received much attention. Phytohormones such as gibberellins play an important role in many aspects of plant growth and development. Gibberellins are known to increase stem elongation by promoting cell division and cell expansion. Different concentrations (50  mg  L^-1, 75  mg , L^-1100  mg  L^-1  ) of gibberellins (GA3) will be sprayed on the foliage of sweet sorghum at 14day intervals for a period of 120 days after sowing, thereafter the height, internode length and diameter  will be measured once a week. The stem juice will be analysed for total sugar content at harvesting.
