  abstract = {{D}etermining the nutritional composition of a pasture is necessary to evaluate its quality, aiming to meet the requirements of feeding animals and guarantee good performance. {T}he quality of the forage biomass produced depends directly on the fertility and type of soil, environmental conditions, and management. {I}n this scenario, the aim was to evaluate the chemical composition, in vitro digestibility of dry matter, and macro- and micronutrient contents of {B}rachiaria brizantha cv. {M}arandu cultivated in soils developed from basalt and sandstone in the state of {P}arana. {A} total of 120 forage samples were collected in a soil developed from basalt and 116 in soil developed from sandstone. {F}orage harvesting occurred in autumn and spring for basalt soil (season effect), and in spring (soil effect) for sandstone soil. {S}oil samples (0-20 cm) were collected in the spring season, at the same forage collection sites, to obtain a greater sample representativity regarding climate-soil-plant relationships. {F}orage samples were separated in leaf blade and stem + sheath, and analyses of dry matter ({DM}), mineral matter ({MM}), crude protein ({CP}), neutral detergent fiber ({NDF}), acid detergent fiber ({ADF}), lignin, cellulose, hemicellulose, in vitro dry matter digestibility ({IVDMD}), total digestible nutrients ({TDN}), nitrogen, and macro- and micronutrient contents were performed. {I}n soil samples, the contents of {P}, {K}, {C}a, {M}g, {M}n, and {Z}n were analyzed. {T}here were season and soil-type effects on the chemical composition of the cultivar studied. {T}he highest levels of protein, {NDF}, {ADF}, lignin, and cellulose were obtained in autumn. {I}n samples from soil developed from basalt, higher levels of hemicellulose, {IVDMD}, and {TDN} were obtained in the spring. {K}, {P}, {M}n, and {Z}n presented levels within the range recommended for the studied forage, but the values of {C}a and {M}g in autumn and {N} in the three studied periods remained below the level considered adequate. {S}oil nutrient contents were influenced ({P} < 0.05) by the soil source material, and the highest levels of {K}, {C}a, {M}g, {M}n, and {Z}n were observed in soil developed from basalt. {F}orage cultivated in spring in the soil area developed from basalt, was nutritionally superior in relation to forage cultivated in the soil developed from sandstone.},
