Description
The present experiment was carried out to obtain some informations about the energy flow and distribution through the soiling plants, every three fractions, and silage made from the fibrous residue (FR) of Italian ryegrass. The early maturing "Minamiwase" and late maturing "Hitachiaoba" were sown 5 Oct. 1983. The experiments were conducted under three times of first cutting (A; 29 Mar., B; 12 Apr., C; 25 Apr.) following regrowth frequencies of 3, 2, and 2, respectively. Dry matter production of both varieties at first cutting was increased accompanying with the growth progressed including spring flush of crop. The percentage of top dry weight of regrowth cutting was lower than that of first cutting, especially on early maturing variety "Minamiwase". The different physiological characteristics were expressed between two varieties by seasonal deviation of environmental factors and were emphasized in chemical and energy storage of crop plant. The calorific value per one gram of dry weight was different among three fractions. Though the value of leaf protein concentrate (LPC) and brown juice (BJ) fluctuated with time, it was kept constant value on fibrous residue (FR) all cutting times through. The efficiency of solar energy storage in each fraction, especially in FR, was the highest at the second cutting and on "Minamiwase", and then it was declined. Energy losses of fractionation process from top and of ensiling process from FR were recognized within 3 and 5 percent, respectively. These results suggest that a practice for this purpose is advisable, using early maturing variety with spring flush and cutting a few frequencies, in warm region of Japan.
