添加標簽 | 總結: | The Nitrogen Fertilization allows the development and different processes, structures, and activators of all enzymes of the plant, being the most nutritious element for the increase of the forage production. In this sense, the objective of the work was to evaluate the ideal of dose nitrogen, on the agronomic behavior and bromatological quality in T. diversifolia. The treatments that are being evaluated are: nitrogen doses (0, 16, 37 and 59 g plant-1 ), with four repetitions, an equalization cut was made and were harvested in a period of 60 days of duration, during the dry season. A completely random design (DCA) was used. The variables were submitted to the analysis of variance and the TUKEY test (P<0.05) to establish the significant differences. Plant height (AP), leaf weight (PH), stem weight (PT), leaf/stem ratio (RHT), TAC growth rate), biomass and production per hectare were evaluated. In addition, the bromatological composition was performed where dry matter, organic matter, crude protein, neutral detergent fiber and acid detergent fiber were evaluated. The AP (T3) 59 g plant-1 was superior to the height of 1.84 cm, however, the PH, PT, RHT, TAC, biomass, and Prod, had similar behavior. MS had a greater increase in T3 with 59 g plant-1 (14.25%), likewise, the highest contributions of PB are evidenced in the T1 treatments:23.83; Q2: 26.25 and T3:26.66%. In however, the MO, FDN and FDA, were equivalent. It is concluded that as it is added in an interval of 16g of nitrogen increasing the values of vegetative development. In addition, it does not influence fibrous fractions (FDN and FDA) in their bromatological composition. Keywords: dosage, nitrogen, agronomic behavior, bromatological composition. |
