The research work was carried out at the National Amazon University of Peru in the Faculty of Agronomy in a livestock project on the Zungarococha farm called "INCREASING DOSES OF BAYFOLAN SOIL AZUL IN THE RESPROUP OF Morus nigra “MORERA” AND ITS INFLUENCE ON FORAGE YIELD IN ZUNGAROCOCHA, PERU – 2022". The evaluations were carried out 45 days after sowing in plots of 3 m x 1.2 m (3.6 m2) and an experimental area of 170 m2. With a design of complete blocks at random (D.B.C.A), with five treatments and four repetitions, the treatments under study were: T0 (0 kilos of Bayfolan/ha), T1 (50 kilos of Bayfolan/ha), T2 (100 kilos of Bayfolan nitrogen/ha ) and T3 (150 kilos of Bayfolan/ha), obtaining the following results: With the T3 treatment (150 kilos of Bayfolan/ha) it was possible to increase the averages of green matter (kg/m2), dry matter (kg/m2) , yield of stems (kg/m2), yield of le...
