Enhancing sugar beet’s early growth and establishment by using protein-based biostimulants

Jolayemi, Okanlawon Lekan


Sugar beet is the only crop after sugar cane that produces sugar for human consumption and industrial usage. Sugar beet is adaptable to temperate climates between latitudes 30 and 60oN. This crop has been around for more than 2 centuries and several efforts have been made to improve its quality (in terms of sugar content) and vigour (seed germination, emergence and seedling establishment). Until now, sugar beet germination capacity has not been fully explored, a problem that has been linked with the presence of germination-inhibitors present on the pericarp. Sugar beet seeds require sophisticated seed enhancement techniques in order to improve their germination capacity, early growth and establishment. Some of the processes involved with sugar beet seed enhancement techniques include polishing, priming, pelleting and coating among others. Seed pelleting involves the addition of some substances to sugar beet seeds in order improve its shape and size for precision planting. Most of these additives are inorganic chemicals, which are dangerous to our environment. To reduce the effects of these inorganic additives on the environment, this paper considers the use of bio-based products (protein-based biostimulants) in seed enhancement techniques. The aim of this paper is to explore the available information on sugar beet seed enhancement techniques, biostimulants, and their impact on germination, emergence, early growth and establishment.
