- Abstract
Tanzania grass (Panicum maximum) is a forage that has stood out in the last years for feeding animals worldwide. Therefore, the evaluation of its growth and production under saline stress is an important factor to enhance the cultivation of this fodder in semi-arid regions. To evaluate the performance of this grass under salt stress, a completely randomized experimental design was established in a factorial scheme (5x2) with four replications, totaling 40 experimental units. Treatments consisted of application of water with five salinity levels (0.5, 1.5, 2.5, 3.5 and 4.5 dS m-1) to the plants via sprinkling and dripping. The components: height (ALT), fresh phytomass (FMF) and dry matter (FMS) of the aerial parts of the plants were evaluated, which were obtained in four successive cuts. High salinity irrigation water reduces FMF and grass FMS, but it is possible to obtain significant results of production with a maximum ECa of 2.8 dS m-1, and maximum reductions of 20% in dry biomass production. When brackish water is used, plants irrigated via drip irrigation presented more significant production results against plants irrigated by spraying.
