“…The high chemical composition (ash content, crude protein content, cellulose content, lipid content and nitrogen‐free extract) was produced by nitrogen of 80–120 kg in the tasseling period for sudangrass, fodder sorghum and their hybrid (Glamoclija et al, 2011). The crude protein content tended to increase with a delay in harvesting time, while acid detergent fiber and neutral detergent fiber content tended to decrease (Choi & Song, 2011). Hence, we focused on the selection of optimum seeding and harvesting dates based on yield for SSH.…”

In general, determining suitable seeding and harvesting times is important in achieving high yields of forage crops in terms of both physiology and ecology. To determine the optimum point, the response surface methodology (RSM) is well known in agricultural science. This study aimed to establish optimum seeding and harvesting dates and to verify the variation of dry matter yield (DMY) for sorghum–sudangrass hybrid (SSH), by determining what we called the “optimum moving RSM” proposed to optimize the RSM in the metadata. The SSH metadata consist of individual experiments (n = 856) that were performed to check the optimum seeding and harvesting dates using classic RSM. However, the SSH metadata failed to produce a single effective equation to determine the optimum seeding and harvesting dates due to the different characteristics of the experimental design. Therefore, the optimum moving RSM was introduced. As a result, we found that the optimum seeding and harvesting dates were clear, based on a single quadratic function. The maximum DMY at the optimum seeding and harvesting dates (the 4th of May and 23rd of September, respectively) was 25,404.50 and 23,697.01 kg/ha, respectively. SSH yield decreases rapidly from 10 days after the optimum date, and seeding and harvesting should be performed within 5 days to ensure a stable yield. Furthermore, the optimum moving RSM is expected to be useful to establish the optimum point in the metadata.

The in vitro experiment was conducted to ensure the supplemental level of spent Flammulina velutipes mushroom substrates (SMS) as an energy source in manufacturing of whole crop sorghum silage. Sorghum harvested at heading stage was ensiled with spent mushroom substrates of 20% (S-20), 40% (S-40) and 60% (S-60) as fresh matter basis for 6 week. The experiment was conducted by 3, 6, 9, 12, 24, 48 hrs of incubation time with 3 replications. The silages were evaluated fermentation characteristics and dry matter digestibility (DMD) in vitro. The pH of in vitro solution was inclined to decrease with elapsing the incubation time, and that of the S-20 was significantly (P<0.05) lower than the other treatment at 48 hr of incubation. Gas production was greater (P<0.05) in the S-20 than the other treatments at 6 and 12 hrs of incubation. The microbial growth in vitro was inclined to decrease following 24 hr of incubation, and thereafter sustained the similar levels. In vitro dry matter digestibility (IVDMD) was lowered by increasing the supplemental level of spent mushroom substrate, and was a low level in the S-60 throughout whole incubation time. Although the IVDMD for S-40 was steadily increased from 9 hr of incubation and reached to similar level with the S-20 at 48 hour of incubation, however SMS for whole crop sorghum silage fermentation might as well add about 20 to 30% in fresh matter basis when considering DMD.
