  • In series of pasture improvement studies with herbicides on nonarable hilly area, the effects of different cutting intervals (10, 20, 30 and 40 days) after glyphosate (2.9 kg/ha active ingredient) application on establishment and development of surface-sown orchardgrass(Dactylis glomerata L.) and ladino clover (Trifolium repens L.) was measured during 1983-1984. The cutting intervals of the existing shrubs after glyphosate application had no differential effect on establishment, seedling vigor, dry matter yield of surface-sown pasture species and botanical composition of improved pasture. Results showed that good control of the existing shrubs for surface-sown pasture species can be achieved by cutting the shrubs from 10 to 40 days after glyphosate application.

  • This experiment was performed in order to investigate the effect of the early grazing management on the forage yield and sward composition of oversown pasture. Two levels of the grazing intensity were treated when the grasses were 15cm, 25cm, and 35cm high. It was observed that the treatment C (light grazing intensity at the 25cm grass height) increased the dry matter yield and the botanical composition of the introduced grasses and legumes. From these facts it is suggested that the early grazing management contribute to the high forage yield and good sward composition of the oversown mountainous pasture and can take the place of cutting or other methods economically.

  • An experiment was carried out ot determine the effects of seeding rates and seedbed preparations on the establishment and yield of surface-sown pasture species. Establishment of orchardgrass was significantly increased by the lowest seeding rate of 20 kg/ha as compared to 30 and 40 kg/ha, but no differences were found between the seeding rates of ladino clover. Both raking and burning significantly improved the establishment of pasture species in comparison with non-treatment. There was a significant difference between the raking and burning for the establishment of orchardgrass, but no significant difference was found between the two treatments for that of ladino clover. Increasing seeding rate of pasture species did not enhance the yield of surface-sown pasture, but both the raking and non-treatment significantly increased the yield of pasture species. The results suggest that both the raking and burning can improve the establishment but increasing seeding rate over 20 kg/ha and burning may not increase the yield.

  • Effects of seed coating on establishment, early growth and herbage production were investigated in Pot, Soil box and Field experiments. Seed was coated with 60% Lime, 20% Phosphate and 20% Peatmoss(W/W), also finely sprayed 13% Arabic gum and 2% Methyl cellulose(W/V). Coating were generally 1:20, seed: coat(W/W). 1. In the general growth of the growing stages and different oversown species at 80 days, seed coated was promoted than none in early growth. (Table 2 and 3) 2. Stand counts at 60 days after oversown, seed coated was higher 15% than none, especially, there was advantage due to coating on the medium and large size seeds such as Orchardgrass, Perennial ryegrass and Kentucky bluegrass, but did not assist establishment of the large (Tall fescue) and small (Ladino clover) size seed. 3. Variation of sward composition was not quite different between two treatments, but seed coated was slightly increased the Percentage of sown grasses with advance of cutting time. 4. Total dry metter yield per unit area with seed coated was higher 17% than none in establishment year. 5. Variations in the chemical composition of the herbage and soil were influenced by coating materials in the coating regime (Table 8). 6. From these facts, seed coated also appeared that adequate seedling stands, early growth and herbage production could be obtained with higher than conventional overseeding method under a poor conditions.

  • This experiment was carried out during 1983-1984 to determine an effective method for the introduction of pasture species on nonarable hill country without cultivation. In this experiment, 1.8 and 2.8kg a.i. $ha^{-1}$ rates of glyphosate and a 0.7kg a.i.$ha^{-1}$ rate of paraquat were applied, and also 30, 45 and 60 days intervals between spraying and sowing were used. Establishment of orchardgrass (Dactylis glomerata) was not affected by the application of herbicides, but that of ladino clover (Trifolium repens) was significantly affected by glyphosate and paraquat. It was found that glyphosate and paraquat have no apparent soil residual activity or pre-emergence effect when sprayed 30 to 60 days before sowing. Dry matter yield of pasture species on the herbicide treatments was significantly higher than that on the unsprayed treatments. The highest yield was obtained from the 1.8kg a.i.$ha^{-1}$ rate of glyphosate 45 days before sowing. Botanical analysis at the final cut showed that the shrubs and native grass of original site were reduced to 5% by glyphosate application, but those on the unsprayed control were still 51%. Crude protein content and in vitro dry matter digestibility of herbage on the herbicide treatments were higher than those on the unsprayed treatments. Results indicated that glyphosate was more effective to control resident shrubs and grass than paraquat, and good establishment and higher yield of surface-sown pasture species can be obtained by spraying 1.8 to 2.8kg a.i.$ha^{-1}$ of glyphosate, 30 to 45 days before sowing.

  • This study was conducted to investigate the effects of existing vegetation on seedling establishment and herbage production of oversown grasses in the Pinus rigida forest. The dominant existing vegetations were Miscanthus sinensis, Festuca ovina, and Lycopodium serratum. In establishment year, seedling stands and herbage production were not affected in Miscanthus sinensis and Festuca ovina, while in Lycopodium serratum it was affected relatively seriously. The pattern of sown species response to the existing vegetations was trend to toward simplified two or three species as Dactylis glomerata, Lolium perenne, and Trifolium repens to advancing the time. Among sown species, Dactylis glomerata was a major dominant species in all existing vegetation area. The content of sown pasture grasses in the sward increased markedly, while the existing vegetations before seeding seriously decreased to advancing the cutting time. The above results shown that the improvement of forest pasture with a surface seeding was better in Miscanthus sinensis and Festuca ovina, but in Lycopodium serratum was found very difficult to improvement of pasture without surface treatment, also establishment method must favor the low herbage production potential.

  • This study was conducted to investigate the effect of some kinds of tree litters covered the soil surface on the germination, establishment, sward composition, and herbage production of the grasses sown by the oversowing method. The litters were leaves of Pinus rigida Miller, Quercus variabilis Blume, Larix leptolepis Gord, and Alnus hirsuta Rupr. The results obtained were as follows; 1. In the Petri dish, germination was affected by grass species and kinds of litters, especially the percolate from Pinus litter seriously suppressed the early germination of small size seeds such as ladino clover and timothy. 2. In the pot, establishment was slightly suppressed in ladino and timothy by the percolate from Pinus litter, while in others it was decreased relatively. 3. Among the 6 species investigated, the small size seeds of ladino clover and timothy and the large size seeds of red clover, they could be early put into the litter spaces and established well. 4. In Larix litter, the establishment percentage of all species were decreased seriously owing to low moisture retention capacity. 5. Grass height and root length were different in kinds of litters and species. 6. The percentages of establishment on each surface treatments of burning, treading, raking, and the control under Quercus tree were 36, 46, 37, and 31%, respectively. 7. The sward percentage of oversown grasses and legumes was 57.8% in burning, 70.9% in treading, 59.6% in raking, and 54.0% in the control. 8. Treading treatment was most effective to destroy existing vegetation and improve soil-seed contact when oversowing and showed the best result. 9. Yield of dry matter per unit area in treading treatment was higher (p<0.05) than those of the other treatments. The above experimental results suggest the importance of direct oversowing on the litters in the mountainous land and forest land.

  • An experiment was conducted to evaluate the effects of seed coating on germination and early growth of tall fescue (Festuca arundinacea Schr.), orchardgrass (Dactylis glomerata L.), and alfalfa (Medicago sativa L.) over sown on unploughed hilly and forested areas. Establishment and early growth of coated tall fescue and orchardgrass on unploughed hilly area were not significantly influenced by seed coating. Establishment and early growth of coated alfalfa on unploughed hilly area were higher than non-coated and showed 4.7% and 4.0 g/m2, respectively. Establishment of coated tall fescue (11.8%) on forested area were higher than noncoated (0.3%), but ealy growth of tall fescue was not significantly influences by seed coating. Establishment of over sown orchardgrass on forested area was not significantly affected by seed coating, but early growth of coated seed (18.7%) was better than that of non-coated (0.3%). Establishment of coated alfalfa on forested area were higher than those of non-coated. Results of this study indicate that the establishment and early growth of over sown tall fescue, orchardgrass, and alfalfa could be improved by seed coating.
