On the recovery and nutritive yield of crimson clover (Trifolium incarnatum L.)

Abstract

1. Studies of the recovery and nutritive yield of crimson clover (Trifolium incarnatum L.) and serradella had been made in 1951. Five varieties of crimson clover and serradella (Se) were used: Auburn (Ab), Autanga (At), Dixie (Di), Mississippi (Mi), Talladega (Ta). The three systems of cutting emplbyed were : C₁, cut every 35 days or 3 times per year C₂, cut every 49 days or 2 times per year C₃, cut at every full bloom stage or 2 times per year 2. Recovery after cutting (green yield) : Mi produced more significant green yield than the other five varieties in C₁, C₃, and Mi, Ta in C₂. However, there were no significant differences in yields between Mi and Ta. 3. Recovery after cutting (oven-dry yield) : Mi produced more significant oven-dry yield than the other five varieties in C₁, C₃ and Mi, Ta, Di and Se in C₂. However, there were no significant differences in yield between Mi, Ta, Di and Se. 4. Recovery after cutting (crude-protein yield) : Mi produced more significant crude protein yield than the other five varieties in C₁, C₃ and Mi, Ta in C₂. However, there were no significant differences in yield between Mi and Ta. 5, On the differences of yield between three cutting treatments, the following results were obtained.C₂ C₃ green yield oven-dry yield green yield oven-dry yield C₁C₂sig. sig. sig. not sig. not sig. not sig.6.
