Abstract: The objective of this study was to evaluate the effect of nitrogen fertilization on tamani-grass managed under cut. The experiment was carried out in the city of Fortaleza-CE, in the year 2017, in a randomized complete block design. The treatments consisted of increasing doses of 0; 100; 300; 600 and 1,200 kg N ha-1, being the experimental unit plot of 2.5 x 5 m, cultivated with tamani-grass. Leaf elongation rate and stem elongation rate behaved in a linear positive manner, with increments estimated to be 0.00141 and 0.00008643 cm tiller-1 to day-1, making 2.20380 and 3.8958 for the doses of 0 and 1200 kg N ha-1 respectively. The total senescence rate was not significant for the nitrogen doses, presenting 0.38 ± 0.18. The leaf life span responded in a linear negative fashion, with reductions estimated to be 0.00723 days. Nitrogen allowed for higher growth and forage biomass of the tamani-grass, handled under cut, without any increase of senescent material. |

Nanoencapsulation is a process suitable for use in reducing degradation of instable components. In this study, chitosan and trimethyl chitosan with tripolyphosphate were used to nanoencapsulate vitamins C, B9, and B12. Analysis of the particle size showed that for a fix proportion of the polymer tripolyphosphate, the system showed a wide variation in size with the amount of added vitamins: e.g., for vitamin B9, the particle size varied from 150±5 nm to 809±150 nm. The zeta potential confirmed that trimethyl chitosan nanoparticles generally had a lower net positive charge (20 mV) than chitosan nanoparticles (40 mV). The encapsulation efficiency was found to be dependent on nanoparticle structure and vitamin solubility, with vitamin B9 the most efficiently encapsulated (approximately 40%). UV-Visible spectroscopy indicated different release profiles for vitamins C, B9, and B12 in a neutral PBS solution with release rates of 36%, 52%, and 16% after 2, 24, and 4 h, respectively. In conclusion the liberation was found to be slower in acidic media. |
