Effects of Mixture of Different Maturity Groups on Dry Matter Yield and Nutritive Value of Oat and Rape in the Fall

This study was conducted to investigate the effects of mixture of different maturity groups on dry matter yield and nutritive value of oat(var. Foothill and Swan) and rape(var. Akela, Ramon and Ember) in the Fall at the Experimental field of Woosuk University, Wanju, in 1998. The results obtained are summarized as follows: 1. Plant height of Foothill was very slightly higher than that of Swan in oat, but there was no significant difference. Also, although there was no significant difference, there was high in plant height of Ember and Akela with Foothill, and Ramon with Swan. 2. Dry matter(DM) yield of Swan was very slightly higher than that of Foothill in oat, but there was no significant difference. Although there was no significant difference, dry matter yield of Akela was the higher in both oats. 3. Acid detergent fiber and neutral detergent fiber content of Swan were very slightly higher than that of Foothill in oat. And it was slightly higher in Akela or Ramon with Foothill, and it was greatly higher in Ember with Swan. 4. In vitro dry matter digestibility(IVDMD) content of Foothill was very slightly higher than that of Swan in oat. And it was slightly higher in Ember with Foothill, and it was slightly higher in Akela with Swan. Also, in vitro digestible dry matter(IVDDM) of Foothill was very slightly higher than that of Swan in oat. And it was slightly higher in Akela with Foothill and Swan. 5. Crude protein(CP) content and crude protein(CP) yield of Foothill were very slightly higher than that of Swan in oat. And it was slightly higher in Akela with Foothill and Swan. The results demonstrated that although there was not significant difference, the mixture of var, Foothill of oat and var, Akela of rape in the Fall was very good for nutritive value and DM yield.
