1. North Region of Kyonggi Province
This experiment was carried out in a split plot design with three replications. The main plots consisted of four different methods such as rye and triticale monocultures and mixed sowing combination with legume(hairy vetch), respectively.
The subplots were consisted of four different applying of cattle manure(0, 50, 100 and 150 kg N/ha).
The dry matter yield and stock carrying capacity(Kcp) of rye+hairy vetch and triticale+hairy vetch mixtures showed a significantly higher values than those of rye and triticale monoculture at the level of 100-150 kg N/ha. An Adequate application level of cattle manure was estimated at the level of 100-150 N/ha and mixture of hairy vetch, it may increase the dry matter production, feed value and stock carrying capacity. K-system balance defined as the difference between nutrient input and nutrient output at the field level based on stock carrying capacity per unit area. Thus, K-system balance, account for the N that is imported in fertilizers(chemical and organic fertilizer), feeds(roughages and concentrates) and also include input of atmospheric deposition N, and exported in livestock products such as gain and excreta from system at field level. Overall nitrogen balance and overall nitrogen efficiency were 12.38 kg N/ha(N-surplus) and 0.96, respectively, in external nitrogen budgets of rye+hairy vetch mixtures. The N surplus as calculated from nitrogen balance is assumed to be a useful indicator of total N losses and its concerning the environmental sustainability of that system.
Nitrogen utilization of internal cycling, crop uptake a nitrogen from the soil was 36.69%, crop nitrogen supplied to livestock feeding was 57.36%, for gain from total input nitrogen was 33.5%, and excreta nitrogen from total nitrogen of livestock production(gain and excretion) was 39.3%, and livestock excreta transfer to a manure was 23.6%, respectively. The ratio of K/Ca+Mg showed an exceed values of potential grass tetany in all forage crops and application levels of cattle manure.
2. Gangwon province
This experiment was carried out in a split plot design with three replications. The main plots consisted of four different methods such as rye and triticale monocultures and mixed sowing combination with legume(hairy vetch), respectively.
The subplots were consisted of four different applying of cattle manure(0, 50, 100 and 150 kg N/ha).
The higher dry matter yield were obtained at the level of 50-150 kg N/ha in rye monoculture, 100-150 kg N/ha in triticale monoculture and rye+hairy vetch mixtures, and 150 kg N/ha in triticale+hairy vetch mixtures than those of other application of cattle manure, respectively. The highest dry matter yield and stock carrying capacity(Kcp) of triticale+hairy vetch mixtures showed a 4.36 ton/ha and 2.57 head/ha at the level of 150 kg N/ha, respectively. Triticale+hairy vetch mixtures is an adaptable seed combination for high quality roughage production in this regions.
Overall nitrogen balance and overall nitrogen efficiency were –. 3.05 kg N/ha(N-deficient) and 1.01 in external nitrogen budgets of triticale+hairy vetch mixtures. Nitrogen utilization of internal cycling, crop uptake a nitrogen from the soil was 35.92%, crop nitrogen supplied to livestock feeding was 58.69%, for gain from total input nitrogen was 35.4%, and excreta nitrogen from total nitrogen of livestock production(gain and excretion) was 39.4%, and livestock excreta transfer to a manure was 23.6%, respectively. The content of minerals and the ratio of K/Ca+Mg showed a low values in all forage crops and application level of cattle manure.
3. North Region of Kyongsang Province
This study was conducted to estimate Hanwoo carrying capacity when rye and triticale as winter forage crops was grown on mixed-sowing of legume forage and applying of cattle manure on the productivity and feed value of rye and triticale during the period of 2012∼2013. The experiment was conducted in a split plot design with three replications. The main plots consisted of three different culture methods such as rye, triticale and mixed sowing combination with hairy vetch or forage pea. The subplots were consisted of four different applying of cattle manure (0, 50, 100 and 150kg N/ha). For rye, annual mean dry matter (DM) yield was significantly (P< 0.05) higher for fertilizer application treatments (9.09∼11.09 ton/ha) than for no fertilizer treatment (8.45 ton/ha), and crude protein (CP) yield was significantly (P< 0.05) higher for forage pea-mixed sowing treatments (0.68 ton/ha) than single-sowing of rye treatments (0.51 ton/ha). Mean CP, total digestible nutrients (TDN) and relative feed value (RFV) contents of legumes-mixed sowing treatments was significantly (P< 0.05) higher than single-sowing of rye treatments.
In case of 450 kg Hanwoo heifers fed diets included 70% forage rye, it is estimated that cattle slurry application (mixed sowing with legumes) plots can rear average 2.9∼3.8 heads/ha a year. For triticale, The amount of DM were increased proportionately corresponded to the applying level of cattle manure, and found significantly (p< 0.05) high at the level of 100 and 150 kg/ha groups. With feed value of forage, The Crude protein (CP) contents was tended to be higher in the mixed-sowing of legume than the single-sowing of triticale. Also the carrying capacity in the single-sowing of triticale was lower than that in the mixed-sowing of legume. Overall, The applying the cattle manure at the level of 100~150 kg/ha and the mix-sowing of legume may increase the productivity per unit area and feed value including CP for improving carrying capacity of organic Hanwoo.
4. Identify the optimal mix of seeding, mix ratio and growing method.
A study was conducted in the central northern area that has a smaller production of winter forage crop compared to the southern areas, in order to identify the optimal mix of seeding, mix ratio and growing method. The study results show that among the mixed seeding of rye and crimson clover, the mix of rye (8)+crimson clover (2) had the largest dry weight of 761kg/10a, which was more than either single seeding of rye or crimson clover. Although there were no quantity differences between different mix ratios, there were differences in quantity between sowing types with sowing in narrow strips producing more than broadcasting seeding. The protein contained in the seeds were highest for triticale(7)+ crimson clover (3) at 9.0%.
In the mix seeding of wheat and crimson clover, the yield of dry weight was highest at 1,353kg/10a for wheat(8)+ crimson clover (2), and overall the yield from mixed seeding was higher than from single seeding of either wheat or crimson clover. No difference in yield was found for different mix ratios. But when different sowing types were compared, broadcasting seeding produced more than sowing in narrow strips. The protein contained in the seeds were highest for wheat(7)+
crimson clover (2) at 10.1%.
