The genotype 12-218 was identified as the most stable genotype for both traits and the genotype 12-231HO was identified as the most unstable genotype for ADF and genotypes 31P41 for NDF (Figure 2g and h). The genotypes TUONO and 12-218 were identified as the most stable genotypes, the genotype BATEM EFE was identified as the most unstable genotype and the genotype BURAK had the least values (Figure 2e). While the genotype DIAN was placed right over the ideal genotype line, the genotypes DKC 6589, DKC 7211 and DKC 6590 were identified as the most stable and the genotype 31P41 was identified as the most unstable genotype (Figure 2d).

Corn silage is an important feed for intensive ruminant production. Combining corn with legumes for silage is a feasible strategy to improve crude protein (CP) concentration in corn silage. This study was conducted to determine silage nutritive quality and fermentation profiles of corn grown in mixture with soybean at different crop combination ratio. In this experiment, corn-soybean combinations of 75:25, 50:50 and 25:75 in addition to monocrops of corn and soybean were evaluated. The crop combination ratio had significant effects on nutritive quality and fermentation characteristics of silage. Silage quality in terms of CP (75:25 ratio 12.23%, 50:50 ratio 12.88% and 25:75 ratio 13.65%) was improved by intercropping compared with corn sole crop (9.91% CP). Increase ratio of soybean resulted in an increase in lactic acid and pH of the mixed silage. Sole soybean gave significantly higher lactic acid (3.57%) and pH of silage (4.33) compared to all other treatments but dry matter concentration was significantly higher in corn monocrop silage (34.34%) than other treatments. The propionic acid and butyric acid content of soybean monocrop and intercrops silage were in all cases higher than sole corn silage. [ABSTRACT FROM AUTHOR]
