This research was carried out to determine some minerals, crude ash, and crude fat contents of second crop forage pea + cereals mixtures, which were sown after wheat harvest in Central Anatolia ecological conditions. The field experiments were conducted in the 2018-2019 years. Mixed cropping was carried out using forage pea at different densities (80, 100, 120 plants m-2), and 25-50 % of the suggested densities of oat, silage maize, and Sudangrass. Results revealed that phosphorus (P) and magnesium (Mg) contents are increasing, but the crude fat content is in a decreasing trend depending on precipitation. Plant densities of forage pea did not cause any significant variation but cereal species caused significant differences in the examined characteristics. Phosphorus content was higher in pea + silage maize mixtures. Especially 25 % oat and pea mixtures had higher Calcium (Ca) content (10163,0 mg kg-1) but increasing densities of cereals decreased Ca content in mixtures. The highest Mg content was 3692,1 mg kg-1 and it was recorded at 50 % silage maize + pea mixed cropping. Crude fat contents of forage pea and warm-season cereals (silage maize, Sudangrass) mixtures remained between 1,6 – 1,8 % but it was higher than 2 % at oat mixtures. The increasing ratio of the warm season cereals caused higher crude ash content in the mixtures and the highest value was determined as 11,68 % in 50 % silage maize and forage pea mixture. Forage pea and 50 % silage maize mixed cropping should be suggested for the high-quality second crop forage production in the region by considering the examined characteristics.
