Abstract

Introduction: Oligosaccharins are poly and oligosaccharides from plant, microbial and animal origin with biological activity in plants as growth and development promotion and anti-stress protection. However, they can be, also, obtained starting from agricultural by-products and polluting fish wastes present in commercial raw materials.
Methods: In this work, national formulations of oligogalacturonides (from citric pectin), chitosans (from crustacean exoskeletons) and lipochitinoligosaccharides (excreted to the culture medium by Rhizobia).
Results: Increased growth and yield in important crops such as, horticultural (tomato, pepper, cucumber), tubers as potato, and grains as beans. They also enhance plant behavior to afford biotic stress, caused by fungal pathogens (Phytophthora nicotianae) and abiotic stress such as drought, salinity, and heavy metal and they allow reducing chemical fertilization in bean.
Conclusion: Those results achieved, supported the development and registration of three new biostimulants that were introduced and extended among Cuban producers.
