Abstract

Guinea grass plant (Panicum maximum) is a perennial plant that stays in the soil for 8 to 10 years and belongs to the Poaceae family. Guinea grass is a typical fodder crop highly productive, especially with climate change conditions. At Cairo's "Sadat" Research Farm, which is connected to the Faculty of Agriculture at Al-Azhar University, a study was carried out, to evaluate the use of A. pinnata (AE) and vermicompost extracts (VE) as biostimulants on the guinea grass plant (Panicum maximum). The experiment consisted of eight treatments (T1, AE 10% - T2, VE 10% - T3, AE 20% - T4, VE 20% - T5, AE and VE 10% - T6, AE and VE 20% - T7, without any fertilizers and T8, chemical fertilizers. In comparison to other concentrations of the biostimulants used, the results indicated that the use of biostimulants from A. binate and vermicompost extracts at a concentration of 20% of each together gave the highest values in the fresh and dry forage yield as well as the highest values in the percentage of protein during the two seasons.
