This study was carried out to determine the effect of silage on
fermentation quality. The silage was produced by forage yield of mixed planting of
corn and soybeans which was planted as a second crop in Mardin ecological
conditions. The field experiment was carried out in a Randomized Complete
Experiment Design with three replications at 7 different planting ratios [corn (C),
70% corn + 30% soybean (70C30S), 60% corn + 40% soybean (60C40S), 50%
corn + 50% soybean (50C50S), 40% corn +% 60 soybean (40C60S), 30% corn +
70% soybean (30C70S) and soybean (S)]. The single (pure) and mixed yield
obtained from each plot were left to fermentation in glass jars for 90 days in four
repetitions. According to the results of the study, the highest fresh biomass obtained
was 71 071 and 68 333 kg ha-1 respectively from 60C40S and 70C30S mixtures,
and the highest crude protein yield was obtained from 60C40S, 70C30S, 30C70S
and 50C50S mixtures planting ratios. As the soybean ratio in the mixture increased,
the CP ratio, silage pH and butyric acid (BA) concentration increased. While the
lactic acid (LA) concentration of corn silage was the highest value with 2.67% in
dry matter (DM), this value has been determined as 1.04% in soybean silage. To
conclude, in regions having ecological conditions of Mardin province, it is
recommended to mix planting with 30% or 40% ratio of soybean plant with corn
plant to increase the protein value of corn silage and improve the fermentation of
soybean.
