Abstract

This work had as objective the effect evaluation of different irrigation levels and nitrogen fertilization on the crude protein content (%PB) of the forage grass Panicum maximum Jacq. cv. Tanzânia. The experiment was carried out at Embrapa Meio-Norte Experimental Area in Parnaíba, Piauí State, Brazil. 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. During the evaluation period, five cuts were taken. The nitrogen fertilization and the irrigation sheet effects were linear and significant. The results showed an increment on grass %PB with the increase in the N and L levels. However, no interaction was observed between these variables.
