Effect of the application of different water depths and nitrogen and potassium doses on quality of Tanzania grass

Abstract

ABSTRACT:The objective of this study was to evaluate the effects of the application of different water depths and nitrogen and potassium doses in the quality of Tanzania grass, in the southern of the state of Tocantins. The experiment was conducted on strips of traditional sprinklers, and used, as treatments, a mixture of fertilizer combinations of N and K 2 O always in the ratio of 1 N:0.8 K 2 O. This study determined throughout the experiment: plant height (PH), the crude protein (CP) and neutral detergent fiber (NDF The lowest level of neutral detergent fiber was 60.7% with the application of the smallest dose of fertilizer and highest water depth. It was concluded in this study that there was an increase in plant height by increasing the fertilizer dose and water depth. The crude protein content increased 5.4% in the dry season, by increasing the fertilizer dose and water depth. In the dry season, there was an increase of NDF content by 4.5% by increasing the application of fertilizer and water depth.
