Effect of Biological Biostimulator on Green bean Root Biomass

The world population continues to grow, there is an urgent need to intensify efforts and innovate to sustainably increase agricultural production. Legumes such as green beans are an excellent source of vegetable protein. In Morocco, the cultivated area of green beans increased from 6,000 hectares in 2017 to 8,000 hectares in 2020, while agricultural production reached more than 200,000 tonnes. This is due to the integration of new agricultural strategies and the use of new monitoring programs. The use of biostimulants as organic fertilizers is proposed to improve crop quality and yield while ensuring greater sustainability of green bean cropping systems. To this end, we proposed to study the efficacy of a biological rooting biostimulant. The results indicate an average increase of 57.32% in root weight from the 90-day growth control and a 59.19% improvement in root length from the 90-day control. This biostimulant shows a very original efficacy in the development of the root system of the green bean plant
