With a Design of Complete Random Blocks (D.B.C.A), with five treatments and four repetitions, the treatments under study were: T0 (control) T1 (10 tons of compost), T2 (20 tons of compost), T3 (10 tons of beef) and T4 (20 tons of beef): obtaining the following results That, for the plant height variable, no significant statistical difference was found (p > 0.05) between the five doses of organic fertilizers, where treatment T2 (40 tons of compost/ ha) obtained 1.69 meters. With T2 (40 tons of compost/ha), higher yields in green matter and dry matter (kg/m2) of 2.89 kg/m2 and 0.61 kg/m2 were achieved. With T2 (40 tons of compost/ha), a plant coverage...
