Evaluación de la frecuencia de corte sobre los rendimientos y valor nutritivo de la biomasa de morera (Morus alba)

The objective was to evaluate the biomass produced at different cutting frequencies and its impact on the yields and nutritional value of mulberry (Morus alba) as an alternative supplement in the feeding of grazing animals. A completely randomized block design (DBCA) was used in 16 plots with 24 mulberry plants each and four cutting frequencies: (T1) 30 days, (T2) 60 days, (T3) 90 days and (T4) 120 days. A quantitative approach with observation and measurement methods was used to analyze biomass production and its nutritional composition, including dry matter, organic matter, ash, crude protein, crude fiber, crude fats, non-nitrogenous extract and gross energy. The data were subjected to tests of normality and homoscedasticity, followed by an analysis of variance, showing significant differences between treatments (<0.0001). The longer cutting intervals produced greater biomass, reaching a maximum of 83.17 g/plot in T4 of 120 days, but with lower nutritional quality. Although dry matter (25.14 ± 0.59%) and crude fiber (23.95 ± 0.24%) increased in T4, crude protein decreased (10.82 ± 0.49%). Treatments T2 of 60 days (4130.51 ± 55.3 Kcal/kg/DM) and T3 of 90 days (4123.4 ±29.59 Kcal/kg/DM) reflected more stable values compared to T4 of 120 days (4114.43 ±20.9 Kcal/kg/DM). In conclusion, the cutting frequency of the mulberry tree affects both the biomass yield and its nutritional quality, with cuts lasting 60 to 90 days being the most appropriate to balance quantity and nutritional value.
