Studies on Hill Pasture Improvement by Hoof Cultivation I. Effect of sowing time on establishment, survival and dry matter yield of pasture species
제경법에 의한 산지초지개량에 관한 연구 I. 초지조성시가 목초의 정착과 잔존 및 건물수량에 미치는 영향
Abstract
In order to find out the effect of sowing time on establishment, survival and yield of pasture species when hoof and tooth cultivation was applied, this experiment was conducted from 1982 to 1984 at the comfound of Alpine Experiment Station. The results obtained are as follows: 1. Grasses establishment of 15 April, 15 May, 1 August and 30 August plots was 11.1%, 9.8%, 12.4% and 3.1%, resulting in 10% establishment in all plots except 30 August. The establishment of legumes in spring sowing was about 30%, showing significant difference (P < 0.05) than that of autumn sowing. 2. Botanical composition of sown pasture in all plots 2 years after sowing ranged from 66% to 80%. There was no significant difference between treatment in terms of DM Production 3 years after sowing although there was the difference in establishment and survival of sown pasture at the beginning of grassland establishment. It indicates that appropriate fertilization and grazing management after sowing play an important role in grassland improvement when hoof and tooth cultivation is applied. 3. The utilization of forages in plot 2 years after seeding was from 45 to 53%.
