Análisis nutricionales y produccion de biomasa de 2 pastos híbridos mulato ii (brachiaria híbrido ciat 36087) y mavuno (brachiaria brizanta x ruziziensis)

Abstract

The present work was carried out at the Faculty of Agricultural Sciences (FCA) of the Technical University of Machala in the Province of El Oro. Where today the pasture is one of the least expensive food for a farmer, a new alternative was sought for the planting of Mavuno and Mulato II hybrid pastures, where the objective of this work was to evaluate the nutritional parameters with which each grass provides, biomass production and recovery time using 2 types of fertilization, the separation of the 2 species of pastures was then carried out. it was subdivided into 2 treatments, where a dose of 5kg of potassium nitrate was applied for treatments 1 of Mavuno and Mulato II, and for treatments 2 a mixture of 5kg of potassium nitrate + 5kg of crushed coal and where a design and sampling completely upward. After 120 days after planting, the first sampling was taken, where with a wooden frame 1 meter long by one meter wide, it was randomly thrown 10 times in different parts of the treatments, this frame was launched to cut all the grass in space, taking the samples; 40 in total, weighed individually to determine the amount of grass produced in one meter, and weights of 580 g were obtained up to 1560 g of grass produced, then an amount of 250 grams of each treatment was taken to send to the laboratory , 3 samples of each treatment 12 were labeled in total for laboratory analysis. In the procedures for obtaining nutritional parameters, the amount of protein, fiber and ash produced was determined. After all the data was taken, everything was organized in Excel spreadsheets and then taken to the spss statistical analysis program. where for the variables, protein, fiber, ash, fats, dry matter and the biomass produced, an anova of a factor was carried out yielding values greater than 0.005, and there was no interaction between the study factors species and combination of treatments, for what which does not exist significance speaking statistically, but seeing from the numerical point of view if changes were observed. Among the values that were obtained in the different variables is: protein for the Mavuno species we obtained 18.97 T1 and 18.87 T2 while 19.03% T1 mulatto II and 18.90 T2 mulatto II, in the biomass variable we obtained T2 Mulato 2. 9.45 t / ha, T1 Mulato 2. 9.27 t / ha, T1 Mavuno 8.67 t / ha, t2 Mavuno 8.50 t / ha, for the fiber variable we had percentages of 44.94% in Mavuno T1 44.51 in Mavuno T2, 36.89 in Mulato 2 T1, 32.69 in Mulato 2 T2. Coming to the conclusion that the 2 species of grasses are important. And that the fertilizer does not influence the production of any of the species so that any of these pastures can be taken into account for feeding cattle.
