Abstract

Abstract The morphoagronomic characteristics along with production yield, bromatological composition and the apparent in vitro digestibility of four cutting ages in Tithonia diversifolia during the dry season were evaluated. The best morphoagronomic characteristics (plant heights, leaf/stem ratio #, leaf weight per plant, stem weight per plant, leaf weight, stem weight, absolute growth rate, biomass per plant and production) were found at 75 days of cutting (1.71 m; 13.24 #; 99.00 g/MS; 217.92 g/MS; 0.61 g MS; 15.94 g MS; 7.46 g MS/day; 316.92 g MS/plant and 5.62 t DM/ha, respectively) and the best leaf/ stem ratio was found at 30 days of cutting g (1.65 g/MS). The best digestibilities for neutral detergent fiber and acid detergent fiber were found at 30 and 75 days of cutting (62.15 and 61.90; 61.18 and 59.70%, respectively). Previo al establecimiento se realizó un análisis de suelo teniendo como resultado un suelo Andisol cuyas características son pH 5.50%; materia orgánica (MO) 20.00%; nitrógeno (N) 26.00%; fosforo (P) 5.00 ppm; potasio (K) 0.27 meq 100/ml; calcio (Ca) 8 meq 100/ ml; magnesio (Mg) 1.40 meq 100/ml, con los siguientes componentes de textura: arena, arcilla y limo de 30.00 37.00 y 33.00%, respectivamente (INIAP, 2019).
