NUNEZ-VAZQUEZ, Miriam de la C. et al. New biostimulant and its influence on the production of common beans. cultrop [online]. 2020, vol.41, n.4  Epub 01-Dic-2020. ISSN 1819-4087.

The use of biostimulants has increased in agriculture in the last years, as an important agroecological practice. Spirulina and vinasse have properties that promote the crop growth and development as well as improve their nutritional quality. The objective of the present paper was to determine the effect of a biostimulant, composed of an aqueous suspension of Spirulina jelly and vinasse, applied alone or in combination with other biostimulants, in the bean grain production. For this, two experiments were performed, using 'Inqueño' cultivar. In the first, two foliar sprays were made with two doses equivalent to 3.5 and 7 L ha-1 of the new biostimulant and in the second, two sprays were also made. The first with the new biostimulant (2.5 L ha-1) and the second one was carried out with the new biostimulant at the same dose or with Quitomax® or with the combination of both. The application of the new biostimulant, composed by Spirulina and vinasse in combination with Quitomax® improved the grain and pod production in bean plants biofertilized with Azofert® and it may be an alternative for increasing the crop production.
