Abstract

The objective of this work was evaluate the effect of different irrigation levels and nitrogen fertilization on the crude protein content (%PB) of Tifton 85 (Cynodon spp). The irrigation depths were applied as a function of Class “A” pan evaporation fractions (ECA) (0.2, 0.6 and 1.0). The nutrient levels used were 100, 200 and 300 kg/ha of N (urea) broadcast applied. The increase of the irrigation sheets didn’t present significant effect on the %PB of the grass, but the effect of the nitrogen fertilization was lineal and significant, occurring an increment of %PB with the increase in the N level. The irrigation depths corresponding to 0.2 ECA and level of fertilization of 300 kg/ha of N presented the best combination, in function of the %PB efficiency production and the possibility of economy of water, on experiment conditions.
