This study was carried out to identify the limitable and adaptable sowing time or transplanting dates and select proper double cropping system in the major upland crops soybean, corn, wheat, potato, sweetpotato and miscellaneous crop which was the foxtail, sorghum, millet, adzuki bean at Suwon, Iksa
This study was carried out to identify the limitable and adaptable sowing time or transplanting dates and select proper double cropping system in the major upland crops soybean, corn, wheat, potato, sweetpotato and miscellaneous crop which was the foxtail, sorghum, millet, adzuki bean at Suwon, Iksan, Milryang, Gangneung, Pyungchang, Muan in Korea for three years.
As a result of study in soybean, the number of seed per plant was the highest at planting 29 June and the lowest at planting 1 August and more in the autumn types than in the summer types and more in 2012 than in 2013. It was observed that one hundred seed weight was reduced rapidly planting at 1 August and heavier in the summer types than in the autumn types and heavier in 2013 than in 2012. Seed yield was the highest at planting 29 June and the lowest at planting 1 August and more in the autumn types than in the summer types and more in 2012 than 2013. As a result of income analyses in double cropping systems based on soybean, corn-soybean cropping system is higher income than that of buckwheat-soybean cropping systems in both paddy and upland field. Income was 3.8 times high in upland and 3.6 times high in paddy field compared to soybean single cropping in Suwon. When three of soybean cultivar is grown in Miryang, southern region of Korea, 30% yield decline than maximum yield occurs in mid-late July planting. To protect the crop from frost damage, the late-maturity cultivar has to be sown before July 20th. The highest economic income was achieved in double cropping with onion than potato or wheat in Miryang.
In the corn, when Yanganok and Singwangok were planted around the middle of June, physiological maturity were about September 30. From this reason, winter crop such as barley and wheat can be planted after harvesting grains of maize. TDN and grain yield of Yanganok and Gwangpyeongok at four different plant date were same or slightly increased and increased at middle of June in paddy and upland field. Yield of potato (first crop, sumi) in upland field were higher than paddy field. Ear property of Yanganok sown at June 19 and July 3 were similar in both paddy and upland field. Fresh weight yield (aerial part, kg/10a) of Yanganok sown at June 19 were 500~700kg/10a higher than those of sown at July 3. From income analyses, Chubaek- Ilmichal and Chubaek-Yanganok cropping systems were best combination in upland field. Chubaek-Ilmichal and Chubaek-Yanganok cropping systems were best combination in paddy field.
Growth period of buckwheat cultivar ‘Yangjul’ is about 56~60 days in autumn, and yield is higher than that of ‘Daisan’ cultivar in Central Region of Korea. For stable production of buckwheat in the middle region, the sowing time limitation of ‘Yangjul’ and ‘Daisan’ is 25 August and 15 August in autumn period, respectively. Through study of sowing time limitation of millet we established the optimal cropping system according to climate change.
Growth period of ‘Hwanggumchal’ cultivar is about 96~108 days, and yield is higher than that of ‘Samdame’ cultivar in Central Region of Korea. For stable production of millet in the middle region, the sowing time limitation of ‘Hwanggum’ and ‘Samdame’ is 27 June in respectively. Through study of sowing time limitation of sorghum we established the optimal cropping system according to climate change. Growth period of ‘Hwanggum’ cultivar is about 110~112 days, and yield is higher than that of ‘Donganme’ cultivar in Central Region of Korea. For stable production of sorghum in the middle region, the sowing time limitation of ‘Hwanggumcha’ and ‘Donganme’ is 27 June in respectively.
Adzuki Bean got higher yield potential as the later sowing in the doble cropping system in Yeongnam area. Chungjupat was earlier in heading & maturing date and the length of stem was longer, the no of grain was much as the earlier sowing but the weight of a hundred grain was lighter. The adaptable sowing time of Chungjupat was between 5th July and 15th July in covered vinyl cultivation method or not. Hongen, was at 5th July in covered vinyl cultivation method and between 5th July and 15th July in without cover cultivation method The highest economic income garlic via sorghum, and than garlic via foxtail, and than garlic via millet, and Rye via miscellaneous in southern double cropping system.
In potato, the average response to planting date was remarkably similar across Gangneung-si and Jinbu-myeon and there seems to be no advantage for early planting dates with ‘Superior’ and ‘Haryoung’, but there was a similar penalty for planting after the critical date in late April(Gangneung-si) and mid May(Jinbu-myeon). In the Gangneung area, increase of mean soil temperature induced reduction of emergence dates and temperature is proper to leaf development until the end of June. This is a key factor in increasing yield of tuber, even if the sowing time was delayed. On the other hand the proper sowing time of soybean was mid-June to July 10th. Thus, potato cultivar ‘Superior’ in order to introduce the soybeans should be sown at the end of March. In the Jinbu area, regardless of planting time high yields were able to be harvested. Growth duration of radish is 50~60 days, and so radish is proper crop to be introduced into potato crops. If there was no reduction in quantity. Thus, Thus, potato cultivar ‘Superior’ in order to introduce the soybeans should be sown at the early of May.
In sweet potato, vein weight of ‘Yulmi’, ‘Singeonmi’ and ‘Dahomi’ varieties was the highest in plots transplanted on 21. May, 5. June, 23. Apr., respectively. The optimal time for transplanting ‘Yulmi’, ‘Singeonmi’ and ‘Dahomi’ was 21 May, while limit time for transplanting three varieties was 5 July, 15 July, and 25 July, respectively.
